Nutrients in foods such as grapefruit, coffee, carrots and tuna can help keep skin healthy in winter, registered dietitian Kerri-Ann Jennings writes. Vegetables with vitamin C, such as broccoli, may reduce dryness and wrinkles; beverages with the flavonoid epicatechin may improve skin texture; and edamame's isoflavones can help protect against sun damage.
Cross-country skiing is a great aerobic winter workout because it increases endurance and uses muscles in the upper and lower body, says Jeremy Fransen, clinical assistant professor of kinesiology and nutrition at the University of Illinois at Chicago. Using snowshoes also is a good workout, and running can still be part of a winter routine as long as runners are dressed appropriately and pick safe venues.
Researchers say women who eat a half cup of rice a day, the U.S. average, are ingesting arsenic equivalent to drinking 4¼ cups of water daily with maximum allowable arsenic levels. The Environmental Protection Agency, which sets arsenic limits for water at 10 parts per billion, should consider arsenic regulations for rice, the researchers say.
Nutrition advice can seem contradictory, especially when study data disagree, but dietitian Jennifer Sygo writes that it is important to remember that science is evolving and it can be difficult to determine how a single nutrient affects health. She writes that data from one study is related only to that specific research and may not apply across populations.
