Handheld pepper mills with black (left) and mixed (right) peppercorns. Pepper gets its spicy heat mostly from piperine derived from both the outer fruit and the seed. Black pepper contains between 4.6 and 9.7% piperine by mass, and white pepper slightly more than that. [52]
Myristicin is a naturally occurring compound (a benzodioxole) found in common herbs and spices, such as nutmeg. [1] [2] It is an insecticide, and has been shown to enhance the effectiveness of other insecticides.
It is a potent irritant for mammals, including humans, and produces a sensation of burning in any tissue with which it comes into contact. Capsaicin and several related amides (capsaicinoids) are produced as secondary metabolites by chili peppers, likely as deterrents against certain mammals and fungi. [ 9 ]
Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and good health. [1] Poor nutrition is a chronic problem often linked to poverty, food security , or a poor understanding of nutritional requirements. [ 2 ]
Piperine (often as "black pepper extract") is often included possibly to improve absorption of other ingredients, and for its supposed ability to improve muscle recovery. [ 46 ] [ 47 ] B vitamins are another common ingredient, most commonly vitamin B 3 and vitamin B 12 in various forms, but also often thiamine (sometimes as sulbutiamine ), [ 48 ...
The debate regarding sterol vs. stanol safety is centered on their differing intestinal absorption and resulting plasma concentrations. Phytostanols have a lower estimated intestinal absorption rate (0.02 - 0.3%) than phytosterols (0.4 - 5%) and consequently blood phytostanol concentration is generally lower than phytosterol concentration.

One review indicates approximately 25% of adolescents, adults, and people over 65, do not meet the Recommended Dietary Allowance for copper. [17] Another source states less common: a federal survey of food consumption determined that for women and men over the age of 19, average consumption from foods and beverages was 1.11 and 1.54 mg/day ...
Because phytic acid also can affect the absorption of iron, "dephytinization should be considered as a major strategy to improve iron nutrition during the weaning period". [38] Dephytinization by exogenous phytase to phytate-containing food is an approach being investigated to improve nutritional health in populations that are vulnerable to ...
