Double-Arm Blood Pressure Checks Detect Hidden Disease

The next time you’re in for a regular medical check-up, it may be an excellent idea to request a blood pressure check in both arms instead of just one.

A recent peripheral arterial disease screening study conducted by researchers at the University of Exeter in the U.K. indicates that doing so may help to detect an otherwise-silent condition known as peripheral artery disease (PAD).

Peripheral arterial disease is defined as a condition where plaque builds up in the arteries that carry blood to the head, organs, and limbs. Peripheral arterial disease typically affects the arteries in the legs, however, it also can affect the arteries that carry blood from the heart to the kidneys, stomach, head, and arms as well.

Individuals who suffer from peripheral arterial disease commonly display symptoms that include painful cramping in the hip, thigh or calf muscles after performing an activity, such as walking or climbing stairs, numbness or weakness in the legs, coldness in the lower legs or feet, especially when one leg is compared to the other, and a change in the color and tone of the skin of the leg that is affected when compared to the other, to name a few.

Losing Weight? Watch Calories, not Carbs or Fat, Study Says

Over the years, countless fad weight loss diets of all kinds have touted the weight loss benefits and effectiveness of restricting all carbohydrates while consuming a diet high that is only high in protein, or restricting fat and allowing carbohydrates, or cutting out all sugar while allowing anything else.

However, a newly published clinical study is indicating that the real (and only) variable related to safely and effectively losing weight is counting the total number of calories consumed, regardless of their source. In other words, the study concluded that a 1,500-calorie-per-day diet will result in roughly the same amount of weight loss whether those 1,500 calories were derived from protein, carbohydrates or fat. (Caveat: consuming too much fat will still raise your risk of certain diseases, including heart disease.)

Undergoing Surgery? Avoid Tryptophan, Study Says

A new study that was conducted by the Harvard School of Public Health is indicating that if you’re about to go under the knife, foods to avoid before surgery include any with tryptophan, the amino acid that was once believed to cause tiredness after eating a large portion of turkey.

In the study, mice that abstained from consuming any form of tryptophan for one to two weeks prior to surgery experienced better survival odds and less kidney damage than mice that consumed their regular diets.

According to Dr. James R. Mitchell, a professor of complex diseases and genetics and one of the lead researchers behind the study, the findings could have a big impact on pre-surgical protocol and procedures.

However, it is not yet known whether the results, which have so far only been achieved in mice, will translate directly to humans. Mitchell said that the ultimate goal of the research is to determine the most optimal diet for those about to endure the physical and mental stress of surgery.

New USDA Mandates to Require Healthier School Lunches

With the obesity epidemic showing no signs of slowing down, one of the hottest topics in the news as of late has been healthier school lunches throughout the United States.

Individuals ranging from television chef Jamie Oliver to First Lady Michelle Obama have sharply criticized school lunch programs for their tendency to serve meals that are packed with highly processed foods, fat, sugar and sodium while lacking in a variety of important vitamins and minerals.

New school lunch standards adopted by the U.S. Department of Agriculture (USDA) will begin to address and change all of that, as schools will be required to follow a stricter set of guidelines dictating the portions and types of foods served to America’s children and teens.

6 Tips for Safe Exercise During Winter

With winter fully upon us and many of the areas of the country experiencing record snow storms, it can be all too tempting to stay inside where it’s warm and cozy rather than exercising outdoors during the cold winter months.

However, if you have regularly exercised throughout the year and are well on your way to achieving your personal health and fitness goals, the last thing that you want to do is discontinue your workout routine through the winter months. Although setting up a personal gym at your home or becoming a member at a fitness center are great ways to stay in good shape during the colder months, many fitness seekers actually prefer the fresh air and exhilaration that comes with exercising outdoors during the winter, performing exercises like jogging, cycling, cross country skiing, and snowshoeing.
