Definitely if you have a cancer dx you should go very low carb. And maximize the functioning of the immune system.
Sadly I know people with cancer and I don’t have the courage to suggest such things. Their doctors don’t even touch on these subjects. My closest friends of course, but distant relatives or kids school people, I just don’t want to put people who probably already disagree on the defensive, when they need support and love.
I think attitude and the kinds of thoughts one allows oneself to dwell upon are huge factors in health and disease. But people are often more resistant to considering new ways of thinking than they are to entertaining new ideas about nutrition or changing the things that they eat.
It seems that we will fight to the death to hold on to our ‘attitudes’, even though changing a point of view - an old resentment, a proclivity toward fear or worry, etc. - would lift so much stress from us...
Are you familiar with the cachexia of cancer. Do you have any notion of the weight loss that occurs in cancer patients? The high metabolic rate of many cancers sucks up most of the nutrients while starving the healthy cells.
