If you want to prevent chronic disease, eat more plant foods and fewer animal or processed foods. The issue is that higher rates of chronic disease cannot be solely attributed to higher life expectancy. There are other reasons, such as changing eating habits in different countries, leading to higher disease rates. For instance, when China switched from a traditional diet of vegetables to processed and animal foods, people were more likely to suffer from heart disease, diabetes, and cancer. A similar trend was seen in other countries.

Deadly diseases prevalent in developed countries are 80% influenced by lifestyle and diet and only 10-20% by genetics. The positive side is that your longevity and good health depend on you. Just four habits can help you stay healthy for a long time: don't smoke, maintain a healthy weight, get at least thirty minutes of physical activity, and eat right by consuming more fresh produce and less meat. These factors have been proven to reduce the risk of chronic disease by 78%.

According to Western medicine, doctors are not paid to give advice on a patient's diet. Instead, they get paid for prescribing medications and performing fat-removal procedures. Studies have shown that a doctor takes an average of 10 seconds to talk to a patient about nutrition, while medical universities offer only 21 hours of training in this area.

Pharmaceutical companies are making billions of dollars. They are hiring more doctors to prescribe or actively promote their products. Marketers perpetuate the myth that the doctor has a cure for any disease. However, the problem with modern medicine is that while it is effective at treating existing diseases, it is ineffective at preventing them.
