Tweets Show Americans Eating Healthier in Pandemic

Tweets Show Americans Eating Healthier in PandemicMONDAY, Aug. 1, 2022 (HealthDay News) -- Whether it's fact or brag, tweets suggest people ate healthier during COVID lockdowns and restaurant closures, a new study finds. Tweets about healthy foods rose 20% between May 2020 and January 2021, while those about fast food and alcohol dropped 9% and 11%, respectively, researchers found."Our findings provide insight into the impact of public health interventions on food and alcohol consumption during the pandemic, and reinforce the idea that when it comes to influencing health behaviors, one’s built environment matters," said lead author Mark Hernandez, a researcher at MIT Lincoln Laboratory in Boston.The switch from fast food to salad or an apple was just one of the dietary changes that people claimed to make during the pandemic's first...

Diets Heavy in `Ultra-Processed` Foods Could Harm the BrainTHURSDAY, July 28, 2022 (HealthDay News) -- Eating lots of ultra-processed foods may dramatically increase your risk for dementia, according to a new study by researchers in China.Ultra-processed foods are high in sugar, fat and salt, but low in protein and fiber. Sodas, salty and sugary snacks and desserts, ice cream, sausage, deep-fried chicken, flavored yogurt, ketchup, mayonnaise, packaged bread and flavored cereals are all examples.Replacing these foods with healthier alternatives may lower the odds for dementia by 19%, the study found."These results mean that it is important to inform consumers about these associations, implement actions targeting product reformulation, and communicate to limit the proportion of ultra-processed foods in the diet and [instead] promote the...

Vitamin D Supplements Won`t Help Your Bones, Large Study FindsTHURSDAY, July 28, 2022 (HealthDay News) -- Seniors who take vitamin D supplements to improve their bone health and ward off fractures are just wasting their time and money, a major new study has found.These supplements did nothing to reduce their average risk of bone fractures, researchers found in a randomized trial testing vitamin D against a placebo."In generally healthy adults, these results do not support the use of vitamin D supplements to reduce fracture risk," said lead researcher Dr. Meryl LeBoff, chief of the Calcium and Bone Section at Brigham and Women's Hospital in Boston. "We found that supplemental vitamin D did not reduce fractures in U.S. participants."In the study, published July 28 in the New England Journal of Medicine, more than 25,000 older adults were randomly...

Eat These Foods, Your Kidneys Will Thank YouTHURSDAY, July 28, 2022 (HealthDay News) -- Eating a rainbow of fruits and vegetables is common advice, but many Americans eat few of these nutrient powerhouses, according to a new study.This includes adults with chronic kidney disease (CKD) who are less likely to eat fruits and veggies than similar people without the disease, said researchers from the University of Virginia (UVA) School of Medicine, in Charlottesville.“Consuming more fruits and vegetables is strongly linked to health in many different diseases,” said Dr. Julia Scialla, a kidney specialist at UVA Health. “We worry about overall health effects when we see patients with CKD consuming low levels of fruits and vegetables. We have to be careful not to unnecessarily discourage healthy fruit and vegetable intake when...

Prehistoric People Drank Animal Milk, Despite Lactose Intolerance

Prehistoric People Drank Animal Milk, Despite Lactose IntoleranceWEDNESDAY, July 27, 2022 (HealthDay News) -- Researchers have long suspected that humans evolved to tolerate dairy products in order to reap their health benefits. Now a new study refutes that idea.Around one-third of the world's population possesses a gut enzyme that allows them to digest lactose, a sugar in milk. Those lucky individuals -- mostly of European heritage -- can feast on dairy products without suffering digestive woes.Exactly why those people exist, however, has never been clear.Nearly all babies can readily digest milk thanks to an enzyme called lactase. But for prehistoric humans, that enzyme would naturally wane and shut down by adulthood -- what scientists term lactase non-persistence.That was, at least, until several thousand years ago, when a gene variant emerged...
