Eat your veggies. Aim for a rainbow of colors every day.
Chew your food. Try 20 times per bite.
But skip the milk, cheese and meat. And while you’re at it, take it easy on the salt, sugar and oil.
That’s just a sample of the advice Phil Eherenman gives students in his seven-week Food for Life cooking and nutrition classes, sponsored by the Physicians Committee for Responsible Medicine, or PCRM, a nonprofit organization started by Neal Barnard, a medical doctor, author and clinical researcher, in 1985.
