Almost half of all Americans take a vitamin supplement, and yet many large-scale, placebo-controlled clinical trials of various supplements have found little or no benefit. A new study led by investigators from Brigham and Women's Hospital suggests an intriguing reason for this: genetic variation may be influencing these effects, increasing risk in some individuals while decreasing risk for others.

Increased levels of antibiotic-resistant bacteria in the environment may have different causes. It could be a consequence of on-site selection from antibiotic residues in the environment, hence promoting the evolution of new forms of resistance.
Most public health guidelines including the Dietary Guidelines for Americans do not allow fat portions in excess. However, nutritionists and dieticians have now agreed that not all fats in the diet are bad and many of them could be allowed.
At present, there is ample evidence to show that not all forms of fats are bad for the heart and some are indeed good for the heart. Some of the fats may help to reduce triglycerides in the blood.
Restrictive diets are hard to stick with, especially when you must eliminate most of your favorite foods. Research has also found that cutting out a particular food can cause cravings and may lead to overindulgence—and weight regain—when you allow yourself to enjoy it again.
Bacon and black coffee for breakfast, or oatmeal and bananas? If you are planning to try to lose weight in 2019, you are sure to find a fierce debate online and among friends and family about how best to do it. It seems like everyone has an opinion, and new fads emerge every year.
Europeans have found the secret to making some of the world's costliest medicines much more affordable, as much as 80% cheaper than in the U.S. Governments in Europe have compelled drugmakers to bend on prices and have thrown open the market for so-called biosimilars, which are cheaper copies of biologic drugs made from living organisms.
Prehospitalization factors, rather than factors linked with an index hospital stay, drove increased risk for readmission among adults aged 65 years and older, according to results from a large study in Denmark.
The effect of vitamin D supplementation on postural muscles of the trunk is of particular interest because low 25-hydroxyvitamin D [25 (OH) D] levels are associated with decreased postural balance and increased risk of falls.
Understanding the role of vitamin D supplementation plays in trunk muscle function of older adults is necessary, as this is a potentially modifiable factor to improve postural muscle function and decrease the risk of falling of older adults.
Genetics contribute to variability in individual response to weight-loss interventions. The objective of this study was to determine the efficacy of a commercially available exercise and weight-loss program and whether alignment of diet to genotype related to lipid metabolism promotes greater success.
Legacy prescribing of certain drugs, such as antidepressants and proton pump inhibitors (PPIs), is common, according to a study published in the November/December issue of the Annals of Family Medicine.
