Another advantage of avoiding sodas is that you will avoid the caffeine that is in many of them. Caffeine is a weak diuretic that causes calcium loss via the kidneys.

I think we have to do everything that's useful. We're doctors. Our job is to tell the truth. And it doesn't have to be embellished in any way.

I don't approve of the use of animals for any purpose that involves touching them - caging them.

If a dog happens to catch a rabbit or another animal, it can very easily remove the hide. If a cat catches a squirrel, they have no trouble with that. But if a person does that, they will work all day and all night to get the skin off of an animal, because they don't have long canine teeth anymore.

While it's certainly true that many people think that dairy doesn't have a cost to the animal, it's because they never went to a dairy farm.

In China, because China is gaining wealth, rice consumption is way down. Rice is a poor person's food, and they're eating less of it. To wait in line at a fast food chain is cool. And they haven't historically had weight problems. So they don't have this culture of, "I need to lose weight."

Dogs have a sense of smell much greater than ours and they're much faster than we are. We have fairly dull senses, fairly slow locomotion. In our Olympic trials, we celebrate speeds that would be an embarrassment to a bird or a dog or another animal.
