Nutrition and Cancer – Cancer 10 – Intensive Dietary Management (IDM)
27.12.2017So, here’s what we are left with.
- Diet plays a large role in cancer
- Cancer is not caused by too much dietary fat
- Cancer is not caused by lack of dietary fibre
- Cancer is not caused by vitamin deficiency
- Cancer is tightly related to obesity
While it may sound trivial, these 5 bits of knowledge took, literally, hundreds of millions of dollars of research money, spread over 25 years to discover. The 5th fact is only gaining recognition within the last few years.
Recently, the CDC released a report “Trends in Incidence of Cancers Associated with Overweight and Obesity – United States, 2005-2014” highlighting the fact that at least 13 cancers are associated, and these accounted for an astounding 40% of all cancers diagnosed in 2014. It comprised 55% of cancers in women, and 24% in men. Worse, the incidence of these obesity associated cancers was increasing rapidly. Adult weight gain of only 5kg (11 pounds) increased the risk of breast cancer by 11%.
What this all means is that cancer is not necessarily a specific vitamin or macronutrient disease (carbs vs protein vs fat). More generally, cancer is concerned with the overall metabolism. Cancer is a metabolic disease at heart. The two most commonly mutated genes in human cancers, p53 and PTEN are now recognized to be intimately related to signals in cell metabolism.
