https://nutritionfacts.org is a website I find useful. Mostly short videos to make research studies accessible to the public. Run by an MD.
here’s part of his commentary on cancer and nutrition:
“Cancer is the 2nd leading cause of death in the United States, and diet may be the leading cause of cancer. The balance of evidence suggests that a whole food, plant-based diet may help prevent, treat, slow, and even reverse cancer progression. It’s never too late to start eating healthier, as cancer risk may drop after starting a plant-based diet at any age.
“Plant-based diets may be effective because they lower methionine intake, inhibit angiogenesis, intercept carcinogens and increase fiber and antioxidants. Populations eating diets centered on whole plant foods have lower rates of cancer. Eating lots of fruits and vegetables—at least nine daily servings—may boost detoxifying enzymes, lower inflammation, lower cholesterol and make for healthier bowel movements, ridding the body of excess estrogen and cholesterol.
“Research studies have focused on many specific foods associated with anti-cancer properties. These include many kinds of fruits, legumes, spices, teas and coffees, vegetables and nuts.
“Consumption of animal products, on the other hand, appears to increase the risk of cancer. Research has shown an association between increased risk of cancer and the consumption of certain foods like cooked meats, dairy, eggs, smoked fish and poultry.
“What’s behind this increased cancer risk? It may be the inflammatory Neu5Gc molecule found in meat. Certain tumors thrive in an inflammatory setting. The insulin-like growth factor (IGF-1) may also been linked to cancer. Heme iron found in the blood and muscle tissue of animal foods may also increase risk of cancer, as may the chemical pollutants in meat, which can lead to premature puberty, putting children at higher risk for cancer later in life.

I disagree that there is no room for animal proteins and fats in our diet. All studies have used commercial feedlot meat and dairy. We are built to eat animals but healthy ones. However, one or two servings of animal protein is plenty in a day. Eggs from pastured chickens living a real chicken life are like perfect food. The entire egg, eaten together.
But yes, our main calories should come from plants. Our bacteria biome is essential and we must feed those babies when we eat. They are as important as we are, cell wise, to our health. One easy way: bake a tray full of potatoes. Chop and pan cook them sliced to eat with your meals, or slice for potato salads. Cooked and cooled white potatoes (go for organic and eat the skin too) have a lot of resistant starch, which our best gut bugs thrive on.
