Before you throw any leftovers away, heed new research that suggests the choice could hit you right in your pocketbook. It turns out that almost one-third of food in American households goes to waste, costing each household thousands of dollars a year, researchers report. “Our findings are consistent with previous studies, which have shown that 30% to 40% of the total food supply in the United States goes uneaten — and that means that resources used to produce the uneaten food, including land, energy, water and labor, are wasted as well,” said study author Edward Jaenicke. He’s a professor of agricultural economics in Penn State’s College of Agricultural Sciences. Jaenicke and his team analyzed data from 4,000 households that participated in a U.S. Department of Agriculture survey and found that, on average, about one-third of the food they obtained was wasted. Nationwide, the cost of wasted food could total $240 billion a year. Divided by the nearly 128.6 million households in the United States, that works out to about $1,866 for the average household. “Based on our estimation, the average American household wastes 31.9% of the food it acquires,” Jaenicke said in a university news release. “More than two-thirds of households in our study have food-waste estimates of between 20% and 50%. However, even the least wasteful household wastes 8.7% of the food it acquires.”… read on >

Whether you’re stopping at a casual fast-food place or sitting down to eat in a full-service restaurant, eating out is an easy way to fill up when you’re hungry. But those meals may not deliver much nutritional value, a new study suggests. The researchers found that 70% of fast-food meals consumed in the United States were of poor nutritional value. For full-service restaurants, around half of the meals were of poor nutritional value. Less than 0.1% of the restaurant meals analyzed during the entire study period — 2003 to 2016 — were considered to be of ideal nutritional quality. “On any given day, nearly one-third of American adults eat at a full-service restaurant, and nearly half at a fast-food restaurant. The nutritional quality of most of these meals is poor and almost none are ideal, and this is true for both quick-serve and full-service restaurants,” said senior study author Dariush Mozaffarian. He’s dean of the Friedman School of Nutrition Science and Policy at Tufts University in Boston. “Today, more American adults are sick than are healthy, and much of this is due to diet-related illness. Looking for healthier restaurant options should be a priority for all Americans,” he added. Over the past 30 years, American meals have largely shifted away from meals prepared at home to restaurant meals, the study authors said. Today, the typical… read on >

Want to know how to avoid blood clots and varicose veins? One physician offers some tips on how to keep your blood vessels healthy. Arteries and veins are collectively known as the vascular system. Arteries transport oxygen and nutrient-rich blood throughout the body, while veins carry de-oxygenated, waste-filled blood back to the heart to be renewed, explained Dr. Chelsea Dorsey, a vascular surgeon from University of Chicago Medicine. Problems can occur in both arteries and veins. It’s estimated that 12%-20% of people older than 60 have peripheral arterial disease (PAD), and more than 40% of women have venous insufficiency, the underlying condition that leads to varicose and spider veins. Blood clots in veins can occur at any age, and people at risk include those who are sick, injured or unable to walk for a period of time, and women who take birth control pills. Varicose veins are more common among younger people, and women are twice as likely as men to be affected, Dorsey noted. Problems in arteries — such as atherosclerosis (narrowing or hardening of the arteries) — tend to increase with age. The health of your arteries and veins is influenced by both genetics and lifestyle. For example, the most common risk factors for varicose veins and venous insufficiency include a family history of these conditions, spending long periods of time on your… read on >

“Food insecurity” — not having enough money to afford sufficient food — increases the risk of premature death, new research suggests. For the study, researchers analyzed data from more than 510,000 adults in Canada between 2005 and 2017. Over the study period, nearly 25,500 people died prematurely. The average life expectancy in Canada between 2008 and 2014 was 82, so deaths at or before that age were considered premature. The study found that, compared with adults who had access to enough food, those with food insecurity were 10% to 37% more likely to die early from any cause other than cancer. Rates of premature death from infectious-parasitic diseases, unintentional injuries and suicides were more than twice as high among those with severe food insecurity compared with others, according to the report. Fei Men, a postdoctoral fellow at the University of Toronto, led the study, which was published Jan. 20 in the CMAJ (Canadian Medical Association Journal). Among the adults who died prematurely, those with severe food insecurity died an average of nine years younger than those who were food secure (59.5 years old versus 68.9 years old), the findings showed. “The significant correlations of all levels of food insecurity with potentially avoidable deaths imply that food-insecure adults benefit less from public health efforts to prevent and treat diseases and injuries than their food-secure counterparts,” the… read on >

(HealthDay News) — Regular nut consumption can lower the risk of heart disease by up to 14 percent, says the American College of Cardiology. Nuts contain heart-healthy fats, protein, vitamins and minerals. The group reminds people that a complete heart-healthy diet should include fruits, vegetables, beans, whole grains, low-fat dairy, fish and nuts. But as one ounce of nuts can contain as many as 200 calories, be mindful of your portion size, the group says.

The Harvard-associated lab that created the “CoolSculpting” process of reducing fat says it’s on the trail of the next advance in nonsurgical slimming. CoolSculpting freezes fat cells by applying an ice-cold gel pad to the skin, causing cells to die off and either be flushed away or absorbed by the body, said lead researcher Dr. Lilit Garibyan, an investigator at the Wellman Center for Photomedicine at Massachusetts General Hospital in Boston. Now her lab is trying to make that process even more effective by injecting an icy liquid slurry directly into fat deposits. In tests with pigs, the injectable slurry containing 20% to 40% ice caused fat deposits to melt away over several weeks, researchers reported recently in the journal Plastic and Reconstructive Surgery. The procedure is headed to human clinical trials next, and researchers hope to have it approved and on the market in a few years, Garibyan said. The U.S. Food and Drug Administration approved CoolSculpting in 2008. Garibyan said it remains the only noninvasive technology the FDA has cleared to reduce and reshape fat deposits in the body. The process works using a principle that you observe every time you open your refrigerator — fats freeze at a lower temperature than water, she said. Butter turns to liquid at warmer temperatures, but solidifies in the fridge, Garibyan said. Water remains liquid at… read on >

(HealthDay News) — With the right amount and variety of foods to meet your nutritional needs, a vegetarian diet can be healthy, says the U.S. Department of Agriculture. The USDA provides healthy eating advice for vegetarians: Think about protein. Incorporate beans, nuts or soy products into your diet. Add calcium. Aside from dairy products, there are many other calcium-fortified foods. Get enough vitamin B12. If you do not eat any animal products, consider a B12 supplement. Check current dietary guidelines to ensure you’re getting the nutrients you need.

If you want to slow down the aging process, it might not hurt to replace whole milk with skim, new research suggests. The study of over 5,800 U.S. adults found that those who regularly indulged in higher-fat milk had shorter telomeres in their cells — a sign of accelerated “biological aging.” The findings do not prove that milk fat, per se, hastens aging, stressed researcher Larry Tucker, a professor of exercise sciences at Brigham Young University in Provo, Utah. But the study does lend support to what U.S. dietary guidelines suggest for adults: If you’re going to drink cow’s milk, opt for low-fat or skim, Tucker said. Telomeres are bits of DNA that sit at the tips of your chromosomes — like the plastic caps at the ends of a shoelace. In essence, they help keep the chromosomes from fraying and sticking together. As people age, their telomeres gradually get shorter, and research has linked shorter telomere length to a higher risk of developing and dying from infections, cancer and heart disease. “A variety of lifestyle factors are also related to telomere length,” Tucker said. Obese people, for example, tend to have shorter telomeres than lean people, as do smokers versus nonsmokers. And people who eat lots of fiber, vegetables and fruit typically have longer telomeres than those who shun those foods. So for the… read on >

(HealthDay News) — It is important to remember that apple cider vinegar is not a magic cure-all. But it does have some health benefits, says the University of Chicago Medicine. The school says the product may: Help control blood sugar. Decrease levels of salmonella in food. Moderately boost the ability to lose weight. But the school says apple cider vinegar won’t: Control high blood pressure. Prevent or cure cancer.

If you need yet another health reason to get enough sleep, here’s one that may wake you up: Science shows that a loss of sleep can make you eat more. And that doesn’t mean healthful salads and green veggies. Studies have shown that total sleep deprivation can trigger a reward system in the brain in response to food stimuli. But until recently researchers didn’t know if there was a similar relationship between everyday sleep loss and the brain’s reaction to food. Researchers looked at volunteers who entered a nine-day study period with a built-up sleep debt. Under ideal sleep conditions, scientists were able to show two things: That even small amounts of sleep loss can put the “brain at risk for hyperactivation to food triggers in everyday life, which could be a risk factor for obesity and lifestyle diseases.” These include metabolic disorder, the first step toward diabetes. Yet on the flip side getting the right amount of sleep appears to reduce this hypersensitivity to food stimuli. The study was published in the journal Sleep. Another study, published in the Journal of Applied Psychology, added work stress to the mix. Researchers found that when people came home after a hard day at work, they were more likely to eat their feelings if they were also sleep-deprived. Simply put, if you don’t get enough sleep, unhealthy… read on >
