High Intake..

A high intake of animal protein, particularly from red and processed meats, is linked to an increased risk of cancer. This is because animal protein can promote the production of growth hormones like IGF-1, which can stimulate both healthy and cancerous cells.

 The effect is more pronounced in middle age, while a moderate intake may be beneficial for older adults, notes Scientific American. 

Growth hormones: Animal protein intake can increase levels of insulin-like growth factor-1 (IGF-1), a hormone that promotes cell growth and can stimulate tumors.

• Specific proteins: A diet high in protein during middle age is linked to a four-fold increase in cancer mortality risk, similar to the risk of smoking, according to Scientific American.
•  High intake of red and processed meats is associated with a higher risk of colorectal cancer. Dairy protein intake may also increase the risk of prostate cancer, notes NIH.   
• Age matters: The risk from high animal protein intake appears to be most significant during middle age. For those over 65, a moderate protein intake may be beneficial for preventing frailty.
• Total intake is key: Maintaining a balance is crucial. The goal is to have adequate, but not excessive, protein intake from all sources.
• Plant protein is beneficial: Plant-based protein is generally linked to better health outcomes and lower mortality risk.
•  Other factors, such as genetics and the overall composition of the diet, play a significant role in cancer risk.    Just a thought.
