“Cancer metabolism” or stress metabolism typically involves an excess of the adaptive hormones, resulting from an imbalance of the demands made on the organism and the resources available to the organism. Excessive stimulation depletes glucose and produces lactic acid, and causes cortisol to increase, causing a shift to the consumption of fat and protein rather [...]
Broda Barnes, more than 60 years ago, summed up the major effects of hypothyroidism on health very neatly when he pointed out that if hypothyroid people don’t die young from infectious diseases, such as tuberculosis, they die a little later from cancer or heart disease. -Ray Peat, PhD A low metabolism affects ALL bodily systems.

“Much of the current concern about the dangers of fructose is focussed on the cornstarch- derived high fructose corn syrup, HFCS. Many studies assume that its composition is nearly all fructose and glucose. However, Wahjudi, et al. (2010) analyzed samples of it before and after hydrolyzing it in acid, to break down other carbohydrates present [...]
Pathol Biol (Paris). 1979 Dec;27(10):615-26. [Biological and pharmacological effects of carrageenan (author's transl)]. [Article in French] Roch-Arveiller M, Giroud JP. Carrageenan is sulfated polysaccharide which has been extensively used as emulsifier and thickening agent in the food industry, for its ability to induce acute inflammation in pharmacology and for its selectively toxic effect for macrophages [...]
For example, the flavonoids, naringenin, quercetin and kaempherol (kaempherol is an antioxidant, a phytoestrogen, and a mutagen) modify the metabolism of estradiol, causing increased bioavailability of both estrone and estradiol. (W. Schubert, et al., “Inhibition of 17-beta-estradiol metabolism by grapefruit juice in ovariectomized women,” Maturitas (Ireland) 30(2-3), 155-163, 1994.) -Ray Peat, PhD Maturitas. 1994 Dec;20(2-3):155-63.

“Estrogen is often said to achieve some of its “wonderful” effects by increasing the effects of serotonin…Many experiments have shown that estrogen is very important for aggressive behavior in animals, and estrogen promotes serotonin’s actions. Some research shows that increased serotonin is associated with certain types of increased aggressiveness, and antiserotonin agents decrease aggresiveness (Ieni, [...]
