People Whose Exercise Is “Fun” Are Less Likely To Snack Heavily Later

People who think of their exercise activities as fun rather than a workout are less likely to chow down on calorie-packed snacks and desserts, two U.S. studies have found. In both studies, participants walked around a lake. In the first, some were told it was an exercise walk, others that it was just a scenic walk. At the subsequent lunch, those who thought they’d been exercising ate 35 percent more chocolate pudding than those on the scenic walk. The second study had the same result: those who thought they were exercising ate 124 percent more calories worth of M&Ms than the scenic – “fun” – walkers.

Cocoa-Rich Dark Chocolate Makes Walking Easier For PAD Patients

Reduced blood flow to leg arteries – called peripheral artery disease or PAD – can make it painful for people to walk. A new clinical study in Italy suggests that eating dark chocolate might provide some relief from the pain, cramping and fatigue associated with PAD. Twenty patients aged 60 to 78 walked on a treadmill in the morning and later after eating 40 grams of dark and milk chocolate on separate days. Participants increased their ability to walk unassisted after eating dark chocolate (85 percent cocoa content and rich in polyphenols), compared to eating milk chocolate. The authors suggested that the polyphenols in the dark chocolate reduced oxidative stress and improved blood flow in the leg arteries.

Orange Honeydews, Cantaloupes Are Packed With Healthful Beta-Carotenes

Researchers at the USDA say that orange honeydew and cantaloupe melons are both rich in beta-carotene, the precursor compound of vitamin A, which is involved in immune function, vision, reproduction, and cellular communication. People in many parts of the world are deficient in vitamin A and lack access to supplements. The researchers said the beta-carotene found in orange-fleshed honeydews and cantaloupes provides a solution to vitamin A deficiency , because it is as readily bioavailable as the beta-carotene found in carrots.

Almonds Reduce Risk Of Heart Disease

A daily serving of almonds in the diet boosts the level of antioxidants and reduces the risk of heart disease, according to British scientists. The study tested the impact of an almond-rich diet on both healthy middle-aged and young men, and on younger men who were both overweight and hypertensive. Researchers found that at the end of the study those who had eaten an almond-enriched diet – 50 grams a day – had higher levels of alpha-tocopherol in their bloodstream, improved blood flow and lower blood pressure, potentially reducing their risk of heart disease.

Link Between Vitamin D Deficiency And High Blood Pressure Found

Australian scientists using “Mendelian randomization” techniques to analyze data from 146,500 people of European ancestry have found that vitamin D deficiency seems to actually actually cause high blood pressure. The finding adds weight to the hypothesis that many cases of hypertension can be alleviated simply through vitamin D supplementation. The researchers said randomized controlled clinical trials are needed to confirm the causality link and the potential clinical benefits of vitamin D supplementation. So far, results of clinical trials have been inconclusive.

Whole Grain Foods, Refined Grain Foods – Kids Will Eat Either Without A Problem

A new U.S. study finds that, despite parents’ beliefs, kids will eat whole grain foods if they are offered. For the General Mills-funded study, 83 middle school students ate either whole- or refined-grain foods for six weeks in 2010. Foods given to the kids included pasta, rice, bread and other foods to eat at home. They were given whole- and refined-grain snack foods to eat at school. Though the kids liked the whole grain snacks served at school the best, they were generally indifferent to whether the other foods they ate were made from whole grains or refined grains. Starting this fall, federal dietary guidelines require schools to offer only whole-grain rich products.

Drugs, Surgery Work Better For Some People Determined To Lose Weight

Research presented at a recent scientific meeting shows that diet and exercise simply don’t work for all people who want to lose weight. In fact, obese and overweight Americans were most satisfied with weight loss surgery (gastric bypass or laparoscopic gastric banding) and prescription weight loss medications when it came to shedding pounds. The U.S. study analyzed data from more than 39,000 respondents to a national health survey from 2012. Thirty-nine percent of obese respondents in the surgery/medication group said they were extremely or very satisfied with their weight loss method, compared to only 20.2 percent of those that used “self-modification”. One disturbing fact: 58 percent of obese respondents were not doing anything at all to lose weight.

Diet Is The Key Factor In Severity Of Arthritis

A U.S. study in mice found that a diet rich in omega 3 fatty acids helped heal injured arthritic knee joints. In humans, arthritis that results from injury accounts for 10 to 15 percent of all cases. For the study, mice were fed one of three high-fat diets: saturated fat, omega 6 fatty acids or omega 6 fatty acids plus omega 3s. Those that ate saturated fat or omega 6 fatty acid diets experienced significant worsening of their arthritis. But mice that ate a small supplement of omega 3 fatty acids had healthier joints. The researchers said the severity of the arthritis was associated with diet, not with the weight of the animals, indicating that just being fat does not induce or worsen arthritis.

Swiss Study Confirms The Value Of A Healthy Lifestyle

An analysis of data from a Swiss survey of 16,721 people aged 16 to 90 from 1977 to 1993 found that healthful behaviors increase life expectancy considerably. Eating fruit, avoiding tobacco, limiting alcohol consumption, and exercising regularly all played a part in extending life expectancy. Of all the factors, smoking seems to be the most harmful, the researchers said. Smokers have a 57 percent higher risk of dying prematurely. An unhealthy diet, not enough physical activity, and alcohol abuse each raised the risk of death by about 15 percent. When all four factors are combined, the risk of early death increases by a factor of 2.5.

Extreme Obesity Significantly Shortens Lifespan

U.S. researchers who analyzed data from 20 large studies demonstrated that very obese people – body mass index (BMI) of 40 or higher – were more likely to die young from cancer and a wide array of other diseases and conditions. Six percent of Americans are now classified as extremely obese, i.e., more than 100 pounds over normal weight. In the study, which examined data from 9,500 extremely obese people, the risk of dying overall, and from most major health causes – heart disease, stroke, diabetes, kidney and liver diseases – rose continuously with increasing BMI. People whose BMI was in the highest range – 55 to 60 – tended to lose nearly 14 years of their lifespan.

“Energy Balance”: The New Mantra For Dealing With Obesity?

Scientists in the U.S. are now touting the idea that diet plus exercise – or “energy balance” – is the proper way to deal with the obesity problem, and should be encouraged by public health policies. In a recent scientific paper, nutrition and exercise professionals – who currently work “in silos” but need to work together – were encouraged to bone up on the principles of energy balance so that their coaching and teaching include all sides of the energy balance message. The paper provided a list of recommendations for tackling the obesity problem at the school and government levels, incorporating the principles of energy balance in curricula and public policies.

Losing Weight Improves Sleep, Mood Patterns

A two-year U.S. clinical study involving 400 men and women confirms that being overweight or obese contributes to poor sleep, and losing weight reverses the situation. The study showed that when obese adults lose even a small percentage of their body weight they show significant improvement in their sleep. People who shed five percent of their pounds by month six of the study reported that they gained an average of 21.6 minutes of sleep a night, compared with only 1.2 minutes for those who lost less than five percent. Those who lost more than five percent of initial weight reported even greater improvements in sleep quality and mood, i.e., symptoms of depression.
