DIABETES DIAGNOSIS BEFORE 50 TIED TO DEMENTIA RISK A study published in PLOS One found that compared to adults diagnosed with diabetes at age 70 or older, those diagnosed with diabetes before age 50 were 1.9 times as likely to develop dementia, while those diagnosed between 50 and 69 were about 1.7 times as likely to develop dementia. The increased risk was especially pronounced among obese adults. “Our study highlights
the importance of one’s age at diabetes diagnosis and suggests that specifically targeting obesity — whether through diet and exercise or perhaps medication — may play a role in staving off dementia in younger adults with diabetes,” said Bei Wu, Ph.D.
SITTING TOO LONG CAN HARM HEALTH, EVEN IN ACTIVE PEOPLE A study published in JACC found that more than 10-and- a-half hours of sedentary behavior each day significantly increases the risk of heart failure and cardiovascular death, even among people who meet the recommended amount of exercise. “The findings of this study don’t surprise me at all,” cardiologist Chauncey Crandall, M.D., told Newsmax. “I see this all the time, even in people who
consider themselves active. The fact is that we basically live in a sedentary society. People no longer work on the farm, or have a little garden, and if they work, it’s at a desk job. So even if they go to the gym for an hour, when they come home, they are likely to sit around watching TV. This creates a problem with endurance, they gain weight, and they develop heart disease,” said Crandall, author of the popular newsletter Heart & Health Alert. “The bottom line is that we were made to move, and sitting for long stretches of time goes against that.”
DEMENTIA STATISTICS 1 in 9
The number of Americans 65 and older who have Alzheimer’s disease, the most common form of dementia
which can result in loss of central vision.
COVID-19 CAN DAMAGE VISION Researchers from UCLA infected mice with the SARS- CoV-2 virus and found that significant amounts of it were found in the eyes. The toxic proteins caused retinal pigment epithelium cells to change shape and become more sensitive to oxidative stress. The changes also lowered the ability of retinal epithelial cells to maintain the blood-retina barrier and caused widespread inflammation in the retina — both major risk factors for age- related macular degeneration,
FRUCTOSE PROMOTES TUMOR GROWTH The high-fructose corn syrup used in beverages and ultra-processed foods promotes tumor growth in animal models of melanoma, breast cancer, and cervical cancer, according to researchers from Washington University in St. Louis. Animals with tumors that were given a diet rich in fructose experienced tumor growth without changing body weight, fasting glucose, or fasting insulin levels. “We were surprised to see that it had a

rather dramatic impact,” said Gary Patti, Ph.D. “In some cases, the growth rate of the tumors accelerated by twofold or even higher.”
CANCER RISK DECLINES IN OLDER AGE Age is considered the most important risk factor for developing cancer because of genetic mutations that build up in cells over the years. But researchers at Memorial Sloan
Kettering Cancer Center
found that advanced age can be protective against cancer. For instance, lung cancer is usually diagnosed around age 70, but once you get to 80 or 85, rates start to drop. “Aging cells lose their capacity of renewal and therefore for the runaway growth that happens in cancer,” said Xueqian Zhuang, Ph.D.
