It is great. I have never read a book that so clearly explains conditions such as cancer and heart disease. Even dementia is dealt with in a way that anyone can understand. Cholesterol, you might be surprised to hear, is not a bad chemical. It is something that our body needs to function properly.
Cholesterol becomes a problem only when it is oxidized.
The French for example, have very high levels of cholesterol, but because it is not oxidized, it is less of a problem to them than it is to Americans. This is because the French, on the whole, take more natural antioxidants in their diet, than do Americans. One of the things that this author points out is that allergies, such as, hayfever, were uncommon before the Industrial Revolution, and were absolutely unknown in Greek and Roman times. This suggests that our propensity to suffer from allergies relates to the effect that industrial pollution has had on our immune system. The other interesting thing is that areas of greatest pollution also have the greatest incidence of childhood asthma.
