This interview contains a lot of delightfully non-dogmatic advice on eating. Some examples:
Should I eat whole-grain bread?
There’s a big difference between white bread and whole-grain bread, and you certainly don’t need to eat bread to have an optimal diet. But an optimal diet leaves room for good bread — whole grain especially — and we think good bread is one of life’s great pleasures. Eat it for that reason.
What kinds of foods do you think will help support weight loss?
Wholesome, whole, unprocessed plant foods in particular. And, any food you eat while riding in the Tour de France.
