Include one glass of milk and one whole egg in your everyday diet. The yolk of the egg should not be thrown away as it is highly nutritious. It is full of fat-soluble vitamins, minerals, protein, and fat. If you eat an egg, you may avoid eating any other meat protein source for the day. Milk will augment your bone health. Cheese is also rich in nutrition and won’t make you bloated unless you eat more than what you burn.
Another study this month, from Mayo Clinic, found that exercise in older people who were formerly sedentary had at least as strong an impact as in it did in young people—at least in the kinds of genes that were expressed. The study also found that these changes were much more robust in response to interval training than to weight lifting or moderate exercise. Which may mean that for some things, the type of exercise we chose matters.
“Being active as we age can play a role in cognitive function, and reduce the risk of disease such as dementia and Alzheimer's,” says Amanda Paluch, a postdoctoral researcher at the Northwestern University Feinberg School of Medicine. “Research has explored several mechanisms, finding that exercise can increase synaptic plasticity and strength of nerve impulses in the brain, and have a positive effect on the hippocampus.”
The skin also serves as a release point for heat. (See “Why Does My Face Turn Red When I Exercise?” for more on that.) When you exercise, your muscles generate a lot of heat, which you have to give up to the environment so your body temperature doesn’t get too high, Hackney says. The heat in the muscle transfers to the blood, which shuttles it to the skin; it can then escape into the atmosphere.
