The foods we eat may have a direct impact on our cognitive acuity in our later years. This is the key finding of an Iowa State University research study spotlighted in an article published in the November 2020 issue of the Journal of Alzheimer’s Disease.
The study was spearheaded by principal investigator, Auriel Willette, an assistant professor in Food Science and Human Nutrition, and Brandon Klinedinst, a Neuroscience PhD candidate working in the Food Science and Human Nutrition department at Iowa State. The study is a first-of-its-kind large scale analysis that connects specific foods to later-in-life cognitive acuity.
When I was a reporter on the Chicago Mercantile Exchange, one of the markets I covered was the Shell Egg Futures market. In that capacity I spoke with egg industry people regularly and found myself eating eggs regularly. Being posted on the exchange floor, it was often handy for me to bring a couple of hard boiled eggs to have for lunch as I couldn’t really leave the Exchange during trading hours. I confess to being a big fan of the incredible edible egg.
Eggs and dairy products are excellent protein sources. Eggs were off the menu for many years for people with elevated cholesterol levels because of their high cholesterol content. However, the latest research has determined that dietary cholesterol (cholesterol from food) doesn’t actually raise blood cholesterol levels for most people, although the saturated fat found in most high-cholesterol foods might. Other research has shown that egg consumption is not significantly associated with a higher risk of coronary artery disease or type 2 diabetes.Continue reading →
Cheese Consumption hits All-Time High; Americans Still Consuming Too Much Beef & Soda Despite Declines, according to the Center for Science in the Public Interest (CSPI)
I’m sure it comes as no surprise to regular readers that the CSPI gives a barely passing grade to the quantity and quality of food we are consuming.
Americans are eating too much of everything, and it’s not just how much, but what we eat, that needs work, according to a report card on the changing American diet published today in Nutrition Action Healthletter.The average American consumes about 2,500 calories per day, according to the U.S. Department of Agriculture estimates. That’s up from about 2,000 calories a day in the 1970s. (my emphasis)
(Ed. note: CSPI is hosting a quiz about America’s Changing Diet. Take it now, if you like, since spoilers follow.)
But how much protein one should eat has long been a controversial topic — muddled by the popularity of protein-heavy diets such as Paleo and Atkins. Before this study, researchers had never shown a definitive correlation between high-protein consumption and mortality risk.
That chicken wing you’re eating could be as deadly as a cigarette. In a new study that tracked a large sample of adults for nearly two decades, researchers have found that eating a diet rich in animal proteins during middle age makes you four times more likely to die of cancer than someone with a low-protein diet — a mortality risk factor comparable to smoking.
“There’s a misconception that because we all eat, understanding nutrition is simple. But the question is not whether a certain diet allows you to do well for three days, but can it help you survive to be 100?” said corresponding author Valter Longo, Edna M. Jones Professor of Biogerontology at the USC Davis School of Gerontology and director of the USC Longevity Institute.
Not only is excessive protein consumption linked to a dramatic rise in cancer mortality, but middle-aged people who eat lots of proteins…
