A new study shows that a modest 4 milligrams of extra zinc a day in the diet can have a profound, positive impact on cellular health that helps fight infections and diseases. This amount of zinc is equivalent to what biofortified crops like zinc rice and zinc wheat can add to the diet of vulnerable, nutrient deficient populations.
Starting a regular program at the gym is a common New Year’s resolution, but it’s one that most people are unable to stick with for very long. Now a study done in mice is providing clues about one of the reasons why it may be hard for so many people to stick with an exercise program. The investigators found that in obese mice, physical inactivity results from altered dopamine receptors rather than excess body weight.
Your microbiota may not be on your side as you try improving your diet this New Year’s. In a new study, researchers explore why mice that switch from an unrestricted American diet to a healthy, calorie-restricted, plant-based diet don’t have an immediate response to their new program. They found that certain human gut bacteria need to be lost for a diet plan to be successful.
Flies with a history of eating a high sugar diet live shorter lives, even after their diet improves. This is because the unhealthy diet drives long-term reprogramming of gene expression, according to a team of researchers.
Researchers put forth the notion of overfat, a condition of having sufficient excess body fat to impair health. After review of current data and scientific studies they argue how, in addition to most of those who are overweight and obese, others falling into the overfat category include normal-weight people with characteristic risk factors for chronic and metabolic disease. This is the first effort to globally quantify those who are overfat versus overweight or obese.
An expert panel has issued clinical guidelines to aid health care providers in early introduction of peanut-containing foods to infants to prevent the development of peanut allergy.
A new comprehensive review examines the potential health benefits of resistant starch, a form of starch that is not digested in the small intestine and is therefore considered a type of dietary fiber. Some forms of resistant starch occur naturally in foods such as bananas, potatoes, grains, and legumes, and some are produced or modified commercially and incorporated into food products.
Older people who followed a Mediterranean diet retained more brain volume over a three-year period than those who did not follow the diet as closely, new research shows. But contrary to earlier studies, eating more fish and less meat was not related to changes in the brain.
Participants in the Why WAIT (Weight Achievement and Intensive Management) program lost substantial amounts of weight, and even those who maintained relatively little loss of weight after five years demonstrated reduced risks of cardiovascular disease.
Scientists have shown in mice that excess pounds can simply be melted away by converting unwanted white fat cells into energy-consuming brown slimming cells. In a recent study, the university researchers show why the inflammatory responses that often occur in overweight people block this kind of fat cell conversion.
