Summarizing: we each are developing minuscule cancer cells most of the time. However, they don't grow large enough to cause ill health due to lack of blood supply. When they do grow larger it's because their blood supply has been enhanced through a process known as angiogenesis. Most of the time, angiogenesis is a normal process for restoring uterine lining and helping heal wounds, but at times certain cancers can stimulateit.
Foods have been identified that can turn off the process, thus starving the cancer cells. Most of the fruits and vegetables I've been eating on my Budwig protocol fall into that category. For instance, red grapes and strawberries are highly anti-angiogenic, so are tomatoes, various teas. The list is long.
Also, related to my overweight status is the fact that fat supports the angiogenesis process and vice-versa. By feeding mice anti-angiogenic preparations, science has demonstrated that weight loss can be triggered by curtailing angiogenesis and weight gain can be stimulated by withdrawing the anti-angiogenic intervention.
So by including anti-angiogenic foods in one's diet, weight loss can be supported while cancer risk can be reduced.
