Now it seems that the notion that fat substitutes will keep fat off our bodies is a big fat lie. That, at least, is the suggestion of a study by Purdue University researchers that found that when rats consumed a fat substitute, signals that could help control food intake were disrupted, and the rats gained weight. The study gave laboratory rats crushed potato chips as a supplement to their diet, and divided the rats into two groups that were given either a low-fat chow diet or a high-fat chow diet. Wait, it gets more complicated: These groups were each split into two smaller groups. One group on each diet was fed a mixture of high-fat chips and the fat-substitute chips, containing olestra, which is a synthetic fat with no calories, while the other group received only regular high-fat chips. After four weeks, rats on the high-fat chow diet gained more weight and developed more fatty tissue when they were given fat-substitute chips compared to the animals that ate only regular high-fat chips. The researchers also found that when the rats that had previously consumed both fat substitute and high-fat chips were moved from a low-fat standard chow diet to a high-fat chow diet, they gained more weight.

    No, not marijuana. The researchers at the University of Washington were looking at drugs like Benadryl, anti-depressants like Sinequan, anti-histamines like Chlor-Trimeton, and antimuscarinics for bladder control like Ditropan.  A university news release reports that the scientists, who tracked nearly 3,500 Group Health seniors participating in a long-running joint Group Health-UW study funded by the National Institute on Aging, found that such drugs, with anticholinergic effects, significantly increased risk for developing dementia, including Alzheimer’s disease, in people who took them for longer […]

    Research Suggests That Exercise Cuts Breast Cancer Risk

    Can exercise really help to ward off breast cancer? Researchers at the University of New Mexico in Albuquerque think so. The Wall Street Journal, reports that scientists at the school have been studying the cancer fighting effects of irisin, a hormone that is released from muscles after vigorous exercise. When the researchers tested genetically engineered irisin on aggressive breast-cancer cells and on nonmalignant breast cells, they found that irisin treatment reduced the number of malignant cells by 34 percent compared with untreated cells, […]

    The Beet Juice Conundrum: Does It Boost Blood Flow?

    For years, athletes have been drinking beet juice before working out to increase blood flow to muscles and boost performance. Now comes a study from researchers at Penn State suggesting that the beet juice strategy was all for naught. A Penn State news release reports that while beetroot juice is in fact rich in nitrates, it did not enhance muscle blood flow or vascular dilation during exercise. The good news, although not necessarily for athletes, is that the researchers found that […]

    Yes, it’s yet another study on the health risks of too much sitting, which is now described, in some circles, as the new smoking. This study, a meta-analysis of others, comes from scientists at Toronto’s University Health Network (UHN) and Institute for Clinical Evaluative Sciences, and like others, identifies a definite relationship between the amount of time a person sits everyday and heart disease, cancer, diabetes, and death. Wait, there’s more unsurprising news.  Science Daily reports that study found that the […]

    If sitting is the new smoking, is standing the healthful alternative? The Boston Globe reports that many experts think it is.

Wait, there’s more, such as a Canadian study involving 17,000 people that found that those who reported the most time […]

HealthDay reports that scientists at the institute put 29 people in casts that completely immobilized their hand and wrist for four weeks. Fourteen of those people were told to routinely perform an imagery exercise, imagining that they were intensely contracting their wrist for five seconds with five seconds of rest. Wait, there’s more: As they performed this imagery exercise, they were […]

    Some wives’ tales turn out to be true. Maybe. A Yale University news release reports that researchers at the school are convinced that the common cold virus can reproduce itself more efficiently in the cooler temperature found inside the nose than at core body temperature, suggesting that there is truth to the popular notion that people are more likely to catch a cold in cool-weather conditions. The researchers examined cells taken from the airways of mice, and compared the immune response to […]
