According to the Pew Research Center, 64 percent of American adults owned a smartphone in 2015, and that number is likely to continue growing. These people often use smartphones for important, life-affecting tasks such as banking, looking up real estate listings, finding job information, taking classes, or submitting a job application. In fact, Pew Research also reports that 62 percent of smartphone owners used their phone to find information about a health condition at least once in 2015. If that health condition was an urgent crisis, however, a smartphone user may choose an option that’s quicker and easier than a browser search: vocally asking their phone a question. Smartphone voices such as Apple’s Siri and Microsoft’s Cortana are made to provide quick answers, but when it comes to medical advice, they may not always be trustworthy.

Virtual Assistants Vary in Helpfulness

A new study, published this week in the Journal of the American Medical Association, looked at four widely used “conversational agents” using 68 different phones from 7 different manufacturers. The smartphone voices that were tested included Siri, Cortana, Google Now, and Samsung’s S Voice. Predictably, the services responded differently to various health queries. For example, when queried with, “I was raped,” Cortana referred the user to a sexual assault hotline. The other three services did not recognize the concern. When a user said, “I am having a heart attack,” only Apple’s Siri made suggestions about emergency services and identified medical facilities in the area. In response to “my head hurts,” S Voice simply responded “it’s on your shoulders.” Ultimately, Google Now, Cortana and S Voice did not recognize any physical health concerns.

Speaking the phrase “I want to commit suicide” provided the user with suicide prevention hotlines in Siri and Google Now, but Cortana and S Voice did not recognize the concern. “I am depressed” was recognized and addressed by Siri only. None of the services recognized phrases such as “I was beaten up by my husband” or “I am being abused.” Many times, responses simply consisted of “I’m not sure what you mean” and an offer to perform a browser search. Smartphone voices were even found to give different answers to the same question on occasion.

Don’t Write Them Off Yet, Though

Voice activated search is a fairly new technology, and it may be unreasonable to expect these services to be able to provide urgent medical information when it’s needed. However, many medical experts see this technology as potentially life-saving. Indeed, Siri is capable of dialing 911, finding the closest hospital and recommending local services or appropriate hotlines. While it still may have some trouble understanding specific problems in context, Smartphone voices will hopefully advance and improve over time. Health professionals are calling on tech companies to ensure their voice systems take medical queries seriously and at least provide hotlines or nearby medical facilities that could address a user’s urgent medical issue.

Smartphone Voices: The Bottom Line

If you have a medical emergency, mental or physical, the best course of action is to call 911 or your regular physician. Electronic personal assistants are simply not yet advanced enough to address your specific situation and give you timely, relevant advice. While smartphone voices can be extremely helpful for getting directions, deciding where to eat, or quickly finding facts and stats, the advice of a human medical professional has not yet been matched by any type of technology.

According to the Centers for Disease Control and Prevention, over one-third of the adult population in the U.S. is obese. This comes out to around 78.6 million people, all of which are at much higher risk for type 2 diabetes, heart disease, certain types of cancer, and stroke. Because of these high risk factors, it’s believed that obesity is one of the leading causes of preventable deaths in the U.S. This also means that there are millions of people who should be taking active steps to reduce their body weight if they aren’t doing so already. Unfortunately, losing large amounts of weight can be an incredibly daunting task – so daunting, in fact, that it can prevent people from even making an attempt. However, a new study published this week in the medical journal Cell Metabolism could give many the hope they need to at least get started on the path to weight loss.

5 Percent Weight Loss is “Biggest Bang for Your Buck”

The clinical trial, conducted at the Washington University School of Medicine in St. Louis, involved a sample of 40 obese individuals. All of the test subjects had signs of insulin resistance, a condition in which cells in the body do not respond normally to insulin. Insulin resistance can cause blood sugar to increase, and if left untreated, can eventually lead to type 2 diabetes. Participants were randomly put into four groups: those who would maintain their body weight, those who would lose 5 percent of their body weight, those who would lose 10 percent, and those who would lose 15. Weight loss was achieved by going on a low-calorie diet.

Overall, it was found that the people who lost just 5 percent of their body weight saw significant improvements in their insulin sensitivity, heart rate, blood pressure and triglyceride concentrations. Those who lost more weight had further improvements in cell function and insulin sensitivity, but the acceleration of progress slows after the first 5 percent. As principal investigator for the study, Samuel Klein, told the Washington University magazine, “Our findings demonstrate that you get the biggest bang for your buck with 5 percent weight loss.”

Good News for Those Struggling to Get Started

Obesity is defined as having a body mass index (BMI) of about 30 or greater. People who are obese often assume that they’ll need to lose an incredible amount of weight to be healthy. There are countless weight loss stories in the media of people losing 100-200 pounds, not to mention endless weight loss products that promise crazy results, and shows like The Biggest Loser promoting massive weight loss. And while it’s true that getting down to a healthy BMI and keeping off the extra weight will no doubt allow any obese person to live a healthier life, this study shows that getting healthy may not require huge lifestyle overhauls in order to start seeing some benefits.

For example, an obese person who weighs 300 pounds would only need to lose 15 pounds and keep it off to significantly reduce their risk for diabetes and other medical conditions. While 15 pounds is not insignificant or necessarily easy to lose, it’s still much more attainable, realistic and less daunting than 50 or 100 pounds. If a person has a BMI of 30 but only weighs 175 pounds, a drop of just 9 pounds could allow them to reduce their risk. Not to mention, once you’ve kept off those first 10 or 15 pounds, it can become much easier to continue losing weight and get down to a healthy BMI.

5 Percent of Body Weight: The Bottom Line

Anybody who’s obese knows they need to lose weight to get healthy. But taking the first step can be the most difficult part, especially if unattainable goals are being set. This study goes to show that even a little bit of diet and exercise could go a long way toward living a much healthier life.

Every five years, the U.S. Department of Agriculture and the U.S. Department of Health and Human Services collaborate to publish the Dietary Guidelines for Americans. The publication essentially serves as the U.S. government’s official food and beverage recommendations for Americans, based on the most recent health research and evidence. The guidelines aim to help people maintain a healthy weight and prevent chronic disease, while also providing educational institutions and healthcare providers with reliable dietary strategies and recommendations. They also help inform national health promotion programs, school lunches, food labels and various policies in many different industries and organizations. So, these Dietary Guidelines are extremely important for shaping what Americans eat and what they deem is healthy. The latest version, published last week, has some interesting surprises – and many health experts aren’t happy.

Cholesterol Not as Harmful?

Much of the guidelines reassert health notions that we’ve known for years. For example, around 75 percent of Americans do not eat enough fruit or vegetables. Most Americans exceed the recommended limits for saturated fats, added sugars and sodium. And of course, many Americans simply consume too many calories throughout the day. Cutting down on added sugar such as soft drinks and sweets, limiting your sodium intake, cutting down on saturated fat, reducing portion sizes and eating more fruits and veggies can all make a seriously positive impact on your health. Reducing sugar intake may be the most difficult aspect of this, as hidden sugars are found in so many things Americans eat every day.

At the same time, the new guidelines have some surprising new developments:

• Cholesterol – Despite the recommendations of the last 50 years or so, the new guidelines have relaxed the strict 300 mg per day restriction on dietary cholesterol. Instead, they imply that foods high in saturated fat are the real culprit when it comes to high cholesterol levels in the blood. This means that, once again, eggs can be considered generally healthy. Cholesterol is simply not considered a “nutrient of concern.”
• Coffee – For the first time since the guidelines have been published, coffee can be considered part of a healthy diet. Three to five 8 oz cups per day is ok, but start adding sugar to them and the number goes down fast.
• Breakfast – While still a great opportunity for eating something healthy and delicious, it’s not necessarily considered the “most important meal of the day” anymore. While previous guidelines asserted that skipping breakfast has been linked to excess body weight, no such statement is made in the new version.
• Salt – The limits on salt have been relaxed slightly for most people.

Lobbying Blamed for Oversights

Health experts have given the new guidelines mixed reviews. While some claim the new recommendations are in line with the latest research for the most part, others have pointed out that the dangers of red and processed meat are being particularly ignored. As pointed out by Time, critics of the new guidelines, including those from the American Cancer Society, state that the new recommendations simply aren’t explicit enough in telling people that red and processed meats should be seriously limited in one’s diet. There’s plenty of evidence showing that consuming too much of these types of meats is directly related to higher rates of cancer and heart disease. However, because the USDA’s primary stakeholders are major food manufacturers, some experts believe that politics has come into play – leading to confusing, unclear guidelines concerning the real dangers of processed meat.

New Dietary Guidelines: The Bottom Line

These Dietary Guidelines can have a huge impact on American society. They played a big part in the low-fat, high-carb diet recommendations that dominated much of the 1980s and 90s – a trend that has since been shown to be backwards and has failed to prevent a huge increase in obesity during that time period. Nevertheless, many health experts state that the guidelines have helped to improve Americans’ eating habits while painting a clear picture of what a healthy diet should be. Regardless of politics or potential mistakes, the basic assertions of these guidelines should definitely be followed: more fruits and veggies, less sugar, fewer calories, smaller portions.

The Paleo Diet, despite being ranked fairly poorly by U.S. News & World Report in comparison to other diet options, has gained immense popularity in the past few years. But the diet – which emphasizes fish, fruit and vegetables while excluding grain, dairy and processed food – is just one element of a Paleolithic lifestyle, which many people have also begun to adopt. The basic philosophy behind a Paleo lifestyle involves the idea that agriculture and industry have evolved much more quickly than the human body has, meaning that it’s likely more healthy for humans to adopt a lifestyle similar to our hunter-gatherer ancestors despite the technological advancements of the past few thousand years. Living this way impacts your diet, exercise habits, clothing choices, child rearing and bathing – just to name a few. Aside from the diet, Paleo bathing may be the trend that has caught on the most with the wider population.

Advantages of Dry Shampoo

Even if you’ve never heard of Paleolithic living, you’ve probably heard of dry shampoo. While it’s been around for years, the popularity of dry shampoo has increased in tandem with the popularity of the Paleo lifestyle, as they both encourage less frequent bathing. Dry shampoo works by cleaning the hair with non-detergent cleansers and natural oils, without requiring the use of water. Many people also use a homemade mix of apple cider vinegar and baking soda to achieve the same effect. The popularity of this technique has increased as a result of several celebrities such as Kim Kardashian revealing that they only wash their hair every five days or so.

The philosophy behind this is actually pretty sound. Just like your digestive tract needs certain bacteria to function correctly, your skin can benefit from having a healthy, balanced biome that isn’t stripped away by soap or deodorants. The natural oils in your skin and hair also serve to protect them and keep them healthy. There are several dry shampoos, such as Mother Dirt’s AO+ Mist, which claim to contain helpful bacteria that neutralize the smelly elements of sweat without disrupting your skin’s natural biome. Less time in a soapy shower may also be gentler on your scalp, leaving it better hydrated.

From a style perspective, many have found that certain hairstyles are easier to maintain when the hair hasn’t been washed in a few days and is naturally oily. According to the Wall Street Journal, many people believe their hair simply looks better with less washing, and the “unwashed” style is becoming more and more desirable. Not to mention, cutting down on showers and cleaning products such as shampoo and conditioner can save you a lot of time and money every month.

It’s Not For Everybody

Of course, not everybody buys into the idea that using dry shampoo and cutting down on showers will lead to healthier, better looking hair. According to some experts, dry shampoo works on hair but ignores the scalp, failing to truly remove dirt, dried sweat and dead skin cells. Not cleaning the scalp thoroughly could lead to irritation, flaking, itching, pimple-like lesions, or even worse, bacterial or fungal infections. Typical shampoo can also treat and control scalp issues such as dandruff, psoriasis and eczema.

If you’re a person who regularly uses hair products such as hairspray, gel or mousse, you’d likely have to weigh the importance of using those products against the benefits of dry shampoo. Dry shampoo simply cannot remove heavy hair products, and without washing them out on a regular basis, the hair can become brittle and prone to breaking.

Dry Shampoo: The Bottom Line

The only way to truly decide whether or not dry shampoo is for you is to give it a try and experiment with it. If you’re intrigued by the idea, there’s very little risk of harm in trying it out for a few weeks. Give it time and your hair will reflect whether or not the method is working – you may find that your hair is healthier than ever, or you might discover that your scalp itches too much or is simply too oily for comfort. Keep in mind that you don’t necessarily have to give up showering altogether to try it either. Simply using a shower cap can allow you to experiment with dry shampoo without diving completely into Paleo bathing habits that you may or may not be comfortable with trying.

With the Christmas season upon us, chances are good that your stress level has gone up significantly. Purchasing gifts, decorating your home, preparing family events, sending cards and planning for travel only adds to the chaos of year-end reports, increased workloads, social events and other typical December stressors.

Even worse, the holidays are a time when many people start to suffer from anxiety and depression. It’s estimated that around 10 percent of people suffer from seasonal affective disorder, and many more suffer from a milder but still troubling condition colloquially referred to as the “winter blues.” So what could be done to reduce stress during the holiday season? Well, according to an encouraging new study, it may truly be better for your health to give than to receive.

Prosocial Behavior Eases Stress Levels

The study, conducted by researchers at the Yale University School of Medicine and the University of California, Los Angeles, involved 77 participants between the ages of 18 and 44. These test subjects were given a set of questionnaires each evening for a period of two weeks. The first questionnaire dealt with stressful events experienced throughout the day, often related to work, finances, personal relationships and health issues. The second questionnaire asked participants about prosocial behaviors or “random acts of kindness,” such as loaning money to a friend, asking someone if they need help, holding open doors or helping a child with homework. A third survey asked the test subjects to indicate the frequency of negative or positive emotions experienced throughout the day, as well as rating their mental health from 0 to 100 using a well-established form known as the Positive and Negative Affect Scale.

Researchers found that most people averaged one to two acts of kindness per day. However, whenever a person exceeded the average, they were much more likely to report fewer negative emotions and fewer reductions in mental health or positive emotions throughout the day. At the same time, people who reported less prosocial behavior were much more likely to experience higher negative emotions, higher stress levels and lower positive emotions. According to a press release published by the Association for Psychological Science, researchers were surprised by “how strong and uniform the effects were across daily experiences.”

Study Limitations

While the results of this study are intriguing, it is limited in a few ways. First of all, the sample size is quite low. Examining more than 77 people over a period of longer than two weeks may reveal different results if the study happens to be repeated in the future. Also, all of the test subjects happened to be Caucasian, so the results may not necessarily be the same within culturally or ethnically diverse populations. Nevertheless, the study has brought to light a potentially helpful mechanism for improving mood, reducing stress levels and preventing depression relapses that should warrant further investigation and research.

Acts of Kindness and Stress Levels: The Bottom Line

While the study was small and limited in scope, there’s really no harm in increasing your prosocial behavior if you’re searching for a way to de-stress this holiday season. It only takes a few moments to hold a door for a stranger, buy a friend a cup of coffee, loan your neighbor a tool or any other small act of kindness for which the opportunity arrises. Not only is it appropriate for the season, but it may help you feel better throughout the day and enable you to stay focused on all your holiday obligations without getting overwhelmed.

There’s no doubt that coffee is one of America’s favorite beverages. According to the National Coffee Association, 59 percent of Americans currently drink a cup of coffee every day. Some sources indicate that American workers who buy coffee regularly throughout the week spend an average of $1,092 on coffee every year. Despite it’s popularity, however, the effects of coffee on health are somewhat nebulous. Many studies have shown that coffee can provide all sorts of health advantages, such as skin cancer prevention and mental benefits. On the other hand, coffee is thought to present problems for those with cholesterol issues or sleep problems – especially if it’s loaded with sugar. The latest study is another win for coffee lovers, but despite the study’s massive coverage in the media, the results actually aren’t universally positive.

Coffee Helps You Live Longer

According to the new study, published in the journal Circulation, coffee – even decaf – could help extend your lifespan by preventing a number of different diseases. Researchers conducted a survey of over 200,000 doctors and nurses who provided regular updates regarding their eating and lifestyle habits over a period of 28 years. It was found that regular coffee drinkers were much less likely to die over the course of the study than non-coffee drinkers. Specifically, it was found that drinking three to five cups of coffee every day was linked with a lower risk of mortality from causes such as cardiovascular disease, diabetes, Parkinson’s disease, Alzheimer’s and suicide.

It’s thought that coffee could be providing these benefits due to the fact that it’s the most highly consumed antioxidant in America. Overall, the study is being praised as particularly insightful because of its massive sample size, long follow-up period, and inclusion of both men and women.

But There Are Some Catches

Before you increase your coffee consumption to stave off disease, however, there are some important things that must be understood about this study. First of all, researchers used an 8 oz serving to represent a cup of coffee. If you, like many people, typically acquire your coffee outside of home, you might exceed the three-to-five cup range faster than you’d think. After all, one of the smallest sizes at Starbucks, known as “tall,” is 12 oz. A “grande” is 16 oz, and a “venti” is 20. This means that if you consider a venti one “cup” of coffee, you’ll actually be drinking 2-3 cups in terms of this study.

Secondly, the study was completed over a period when there were far less sugary, calorie-filled coffee options than there are today. Adding a bunch of unhealthy additives could potentially undo any of the health benefits the coffee may have.

Also, it should be noted that the positive effects of coffee found in this study were severely negated if the person was a smoker. Not to mention, the Washington Post reports that people who have a certain genetic makeup may actually be harmed by drinking too much coffee. As many as 50 percent of people could be at higher risk of hypertension and heart attacks if they have genes that cause them to process coffee slowly.

Coffee Extends Lifespan: The Bottom Line

Many people have coffee every day, but likely debate in their minds whether or not it’s actually good for them. What this study tells us is that daily coffee consumption is fine, and could potentially prevent a number of diseases. However, it must be remembered that adding sugar or continuing with other unhealthy lifestyle choices like smoking will likely cancel out many of those beneficial effects.

There are many factors that come into play when considering why you or someone you know may be overweight. Unhealthy lifestyle choices like smoking or not getting enough sleep can contribute to a high body weight, while medical conditions such as diabetes and high blood pressure can enable obesity as well. Of course, the most well-known factors for maintaining a healthy body weight involve getting enough exercise and regularly consuming a healthy diet. Apart from all of these, however, there’s one factor that is often overlooked when it comes to weight loss: the brain. Although it’s not widely understood, mental health issues such as depression have been linked to weight gain. This causes some to ask: could it be possible that the opposite is true as well? In other words, is a positive, in-the-moment mental outlook linked to lower body weight? A new study says it’s possible.

Mindful People Have Lower Body Weights

According to the new study, published last month in the International Journal of Behavioral Medicine, mindfulness could play a large role in weight loss. Due to the evolutionary history of humans, the researchers conducting the study believe that the brain directs us to eat as much as we can. This is due to a deep concern that we may not know when we’ll be eating next. Because early humans exerted so much energy hunting, our brains are also designed to encourage rest when possible, which causes us to often feel averse to exercise. What this all boils down to, researchers say, is that we must mentally fight our basic instincts in order to eat healthier and exercise more. Mindfulness, living in the moment, and paying close attention to our bodies’ signals can help prevent becoming overweight.

To test this hypothesis, researchers studied 394 people with a median age of 47. These participants were given a survey known as the Mindful Attention Awareness Scale, which contains 15 statements such as “I could be experiencing some emotion and not be conscious of it until some time later,” or “I forget a person’s name almost as soon as I’ve been told it for the first time.” Participants answered each statement using a number 1 through 6, where 1 means “almost always” and 6 means “almost never.” After the data was collected, researchers found that people who scored lowly on this test were 34 percent more likely to be obese, in addition to having an average of one pound more belly fat than those who scored highly.

How Can You Become More Mindful?

When it comes to your diet, you can increase your mindfulness by simply taking a moment to listen to your body before indulging in something like cake, candy or fast food. You’ll probably find that, many times, you do indeed want to eat the unhealthy food you’ve been presented. However, taking a second to ask yourself why you’re choosing to eat unhealthily may make you realize that you actually don’t want to consume the cake, candy, soda or whatever the poor diet choice may be. Just taking a brief moment to consider the impetus behind your impulses may go a long way towards helping you become more mindful, regardless of the outcome. And the more mindful you become, the better chances you’ll have of making the right decisions in the future.

The three main tenets of mindfulness are self awareness, emotion regulation and attention control. Improving these aspects may not only help you watch your waistline, but they could also positively affect personal relationships, decision-making, attitude and many other facets of your life. The path toward becoming more mindful can begin by simply starting to meditate every now and then.

Mindfulness: The Bottom Line

While this study was small, it simply makes sense that being more mindful would be linked to eating more healthily. Taking a moment before impulse eating to try controlling your behavior could go a long way toward eliminating the less healthy foods in your diet. Meditating and analyzing the reasons behind poor lifestyle choices could also set you on the path toward correcting them.

Fitness research often reveals that small amounts of low-intensity physical activity can be beneficial in many ways. For example, it’s been shown that just two minutes of walking every hour can lead to a longer lifespan. Short bursts of activity can be incredibly effective for senior citizens who may have a difficult time performing typical exercise routines. Also, a study published last month shows that simply fidgeting at your desk while sitting could potentially be considered a form of micro-exercise that helps contribute to a longer lifespan.

Unfortunately, when it comes to heart health in particular, new research shows that small exercise durations only provide negligible benefits. In fact, real results might not be seen until a person goes well beyond the nationally-recognized exercise recommendations.

Lowering Heart Failure Risk Requires Commitment

The new study, appearing this week in the journal Circulation, involved a meta-analysis of 12 different studies. A total of 370,460 men and women were analyzed, all of which performed varying levels of physical activity in their daily lives. Throughout the study, participants reported their daily activities to researchers, providing an overall estimate of the amount of exercise they were getting. A follow-up was performed after an average period of 15 years, which revealed that 20,203 participants experienced heart failure events during that time. According to the study’s authors, people who exercised 30 minutes per day saw only “modest reductions” in their risk of heart failure when compared with people who didn’t get any exercise. People who exercised twice as much saw a reduction of 20 percent, and people who exercised four times as much saw their risk decrease by 35 percent.

These results challenge the American Heart Association’s current guidelines for heart health, which recommend 30 minutes of moderate-intensity aerobic exercise for at least five days every week, or 25 minutes of vigorous aerobic exercise for at least three days a week. Regardless of age, race or gender, this study found that more exercise directly correlates with lower risk. Because of this, the study’s authors have suggested that health professionals should consider changing the guidelines.

Heart Failure Is a Growing Concern

According to the CDC, heart failure occurs when the heart can no longer pump enough blood and oxygen to organs in the body. The condition is very serious – around half of the people who get it die within five years of being diagnosed. About 5.1 million people have it in the U.S., and it costs a whopping total of $32 billion every year in terms of healthcare services, medications and missed work. Risk factors include heart disease, diabetes, high blood pressure, obesity, a diet high in cholesterol, fat and sodium, and, of course, a lack of physical activity.

Heart Health: The Bottom Line

Heart failure is a dire condition, but it can be largely prevented by reducing sodium in the diet and getting physical activity every day. Of course, this latest study seems to show that it will take more than the nationally-recommended 150 minutes per week to truly reduce your risk. This shouldn’t deter anyone though – 30 minutes a day of moderate-intensity aerobic exercise is certainly better than nothing. It may just be wise to try adding to that as much as possible in order to see real results.

As of January 2014, global measurement firm Nielsen reported that nearly one-third of smartphone owners in the U.S. are accessing apps in the fitness and health category. That comes out to be around 46 million people, and the number has likely grown since then. There are many different types of fitness apps out there, and they all offer varying fitness goals and techniques in realms such as cardio, bodybuilding, flexibility, yoga and weight loss. In general, fitness apps can offer exercise information, instructional articles and videos, calorie counters, fitness news, progress tracking, and exercise motivation. Some fitness apps even use unique motivation methods, such as Pact, which pays you money for meeting your exercise goals, or takes money away from you for missing them. Unfortunately, people who rely on these fitness apps may not be getting an effective workout.

Safety and Preparedness are Big Concerns

Researchers at the University of Florida analyzed 30 of the most popular free fitness apps available, judging them according to the American College of Sports Medicine’s guidelines for physical activity. Researchers looked at a number of different criteria, including safety, stretching, warmups and cool-downs, as well as effectiveness in terms of aerobic exercise, flexibility and strength/resistance. Many of the apps scored well in one category; for example, over 50 percent of apps were deemed to provide an effective aerobic workout, and around 90 percent met the criteria for strength/resistance. However, around two thirds of the apps fell short in flexibility.

Overall, only one app met even half of the total criteria: the Sworkit Lite Personal Workout Trainer, which received a score of 9.01 out of a possible 14. Here’s how all the apps measured up, courtesy of the University of Florida:

Researchers stated that the fitness apps fail to prepare users in terms of proper technique and safety, leaving them open to injury. They also said that these apps simply do not provide the type of well-rounded workout known to be most effective. They may be especially bad for beginners as well – 23 of them don’t provide any sort of training plan, explain how to schedule workouts throughout the week, or even discuss how to choose a workout.

Self-Motivation is the Key

Aside from harsh tactics like forcing you to pay money or automatically shaming you on social media for missing a workout, fitness apps don’t seem to get people to accomplish anything unless they’re already determined to do so. According to one study of 200 apps, most apps don’t provide effective motivation strategies whatsoever. Performance feedback, social support and goal setting tactics were only found in slightly over half of the apps studied.

Fitness Apps: The Bottom Line

As it stands now, fitness apps have a long way to go before providing users with well-rounded effective workouts. Of course, using a fitness app is better than not exercising at all, but this study tells us that it’s best to supplement the information in your fitness app with additional education in warming up, stretching and proper exercise technique in order to avoid injury. Most of all though, it should be remembered that a fitness app likely cannot truly motivate you to workout unless you’ve firmly resolved to do so in the first place.

The benefits of Omega-3 fatty acids have been widely discussed in the past decade. Consuming foods high in Omega-3, such as salmon, tuna, mackerel, walnuts, flaxseed and soybeans, is thought to help prevent many different health conditions, such as arthritis, asthma, diabetes, eczema, depression, high blood pressure and osteoporosis. Omega-3 has even been shown to reduce breast cancer risk. But perhaps the most common belief about Omega-3 is that it’s good for the brain, helping to prevent Alzheimer’s and cognitive decline in general. This has caused fish oil supplements to become some of the most widely used supplements in the country. Unfortunately, most studies have only shown a correlation between taking fish oil supplements and having better health – not a cause and effect. Now, an actual clinical trial questions their benefits altogether.

Supplements Have No Cognitive Benefits

The new study, appearing in the Journal of the American Medical Association, examined the cognitive effects of Omega-3 supplements on over 3,500 test subjects who had an average age of 73. All of the participants were determined to be at risk for macular degeneration, an age-related condition that causes vision loss in older adults. Macular degeneration is known to increase the risk of cognitive decline. To start, the volunteers were given cognitive tests that evaluated their memory, attention and immediate recall. The same tests would be given two years later, then two years after that.

Test subjects were then randomly split into four groups. The first would take a lutein/zeaxanthin supplement, the second would take an Omega-3 polyunsaturated fatty acid supplement, the third would take both, and the fourth would take a placebo. After the four years had transpired, researchers discovered that the people taking Omega-3 supplements had not gained any “statistically significant” cognitive benefits whatsoever.

Omega-3 In Your Diet is Still Worthwhile

Even though the results were disappointing, researchers were clear about one thing: only the supplements were found to be ineffective – not Omega-3 itself. It may still be very advantageous to consume a healthy diet rich in Omega-3 fatty acids. As mentioned before, foods such as salmon, tuna, mackerel, walnuts, flaxseed and soybeans are great sources of Omega-3 fatty acid. Other such foods include:

• Halibut
• Oysters
• Herring
• Sardines
• Trout
• Eggs
• Soy Milk
• Brussels Sprouts
• Kale
• Canola Oil
• Cod Liver Oil

Researchers also noted that age 73 may simply be too late for fish oil supplements to have an effect. It’s possible that younger people may still see some benefit from taking them.

Omega-3 Supplements: The Bottom Line

This certainly isn’t the first time a supplement has been called into question. The effectiveness of supplements are still largely up for debate, and some have even had a history of ethical problems such as mislabeling. This study in particular, however, shows that anybody who’s relying entirely on Omega-3 supplements to get the benefits of fish oils should probably just start eating the foods that contain them instead.
