How Not to Die: Discover the Foods Scientifically Proven to Prevent and Reverse Disease

Eggs (along with soda) have also been associated with asthma attacks in children, along with respiratory symptoms, such as wheezing, shortness of breath, and exercise-induced coughing.51 Removing eggs and dairy from the diet has been shown to improve asthmatic children’s lung function in as few as eight weeks.52

The fumes produced by frying bacon contain a class of carcinogens called nitrosamines.31 Although all meat may release potentially carcinogenic fumes, processed meat like bacon may be the worst: A UC-Davis study found that bacon fumes cause about four times more DNA mutations than the fumes from beef patties fried at similar temperatures.32

On the other hand, a twin pair of studies from Columbia and Harvard Universities found that consumption of cured meat—like bacon, bologna, ham, hot dogs, sausage, and salami—may increase the risk of COPD.38,39 It’s thought to be due to the nitrite preservatives in meat, which may mimic the lung-damaging properties of the nitrite by-products of ciga

There’s an enzyme in the roots of bristlecone pines that appears to peak a few thousand years into their life span, and it actually rebuilds telomeres.68 Scientists named it telomerase. Once they knew what to look for, researchers discovered the enzyme was present in human cells too.

Some people have expressed concern that boosting telomerase activity could theoretically increase cancer risk, since tumors have been known to hijack the telomerase enzyme and use it to ensure their own immortality.75 But as we’ll see in chapter 13, Dr. Ornish and his colleagues have used the same diet and lifestyle changes to halt and apparently r

Carcinogen-Blocking Effects of Turmeric The Indian spice turmeric, which gives curry powder its characteristic golden color, may also help prevent some of the DNA damage caused by smoking.

In general, the dividing line between health-promoting and disease-promoting foods may be less plant- versus animal-sourced foods and more whole plant foods versus most everything else.

as the fumes from pan-fried fish have been found to contain high levels of PAHs capable of damaging the DNA of human lung cells.29 Given the excess cancer risk, the researchers concluded that it wouldn’t be safe to live near the exhaust of a Chinese restaurant for more than a day or two a month.30

Cancer risk may also depend on what’s being fried. A study of women in China found that smokers who stir-fried meat every day had nearly three times the odds of lung cancer compared to smokers who stir-fried foods other than meat on a daily basis.25 This is thought to be because of a group of carcinogens called heterocyclic amines that are formed w
