Tufts University's Modified MyPyramid for Older Adults emphasizes nutrient-dense food choices and the importance of fluid balance. It also provides guidance about forms of foods that could best meet the unique needs of older adults and about the importance of regular physical activity. "Adults over the age of 70 have unique dietary needs, " says first author Alice H. Lichtenstein, DSc, director of the Cardiovascular Nutrition Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts (USDA HNRCA).

The produce section may be a bit bare this time of year, but that doesn't give anyone a free pass to skimp on fruits and vegetables. Dr. Jo Ann Carson, professor of clinical nutrition at UT Southwestern Medical Center, said the solution lies in choosing as much fresh seasonal produce as possible, then augmenting it with a mixture of frozen and canned offerings. Frozen fruit and vegetables often contain nearly as many nutrients as fresh produce because it has been picked, frozen and packaged at the peak of its season, she said. Dr. Carson also said that some canned vegetables, including pumpkin, provide more vitamins per serving than their fresh counterparts.

"If climate change and population growth progress at their current pace, in roughly 50 years farming as we know it will no longer exist, " which means that the "majority of people could soon be without enough food or water, " Dickson Despommier, a professor of public health at Columbia University, warns in a New York Times opinion piece. "But there is a solution that is surprisingly within reach: Move most farming into cities, and grow crops in tall, specially constructed buildings. It's called vertical farming, " he writes.
