Nearsightedness is a growing problem worldwide. While genes and developmental factors play a role in whether a child becomes nearsighted, research suggests that spending time outdoors can lower a child's risk of developing this condition.

A 2022 study found a 31% reduction in Americans' use of prescription sleep aids from 2013 to 2018. The drop-off was even sharper among people 80 and older, who were 86% less likely to use FDA-approved sleep drugs by the end of the study period.

A 2022 study found that women ages 35 to 69 who ate vegetarian diets were significantly more likely to break a hip than peers who ate fish or meat. Vegetarians need to be sure they get adequate amounts of dietary protein, calcium, vitamin D, and other micronutrients to maintain bone health.

Fermented foods and drinks such as kimchi, kombucha, and tempeh are increasingly popular, adding to mainstays such as yogurt, sauerkraut, and beer. Heat and bright lights during manufacturing can destroy some beneficial probiotics. Fermented products can ease digestion, dampen inflammation, boost nutrient absorption, and battle harmful bacteria. People should look for product labels that say "live and active cultures" and avoid shelf-stable versions, which don't contain probiotics.

Over-the-counter supplements touted to support prostate health are popular, and supposedly help prevent and manage symptoms of an enlarged prostate (benign prostate hyperplasia). Some of the ingredients are said to protect against prostate cancer or slow its growth. While research has explored supplements' role in prostate health and some had positive results, the findings are far from conclusive. A better dietary option for prostate health is to follow a plant-based diet like the Mediterranean or DASH diet.
