Dietary supplement
According to US & Canadian Dietary Reference Intake guidelines, the protein Recommended Dietary Allowance (RDA) for adults is based on 0.8 grams protein per kilogram body weight. The recommendation is for sedentary and lightly active people. Scientific reviews can conclude that a high protein diet, when combined with exercise, will increase muscle mass and strength, or conclude the opposite. The International Olympic Committee recommends protein intake targets for both strength and endurance athletes at about 1.2-1.8 g/kg body mass per day. One review proposed a maximum daily protein intake of approximately 25% of energy requirements, i.e., approximately 2.0 to 2.5 g/kg.
Ochratoxin A
EFSA established in 2006 the "tolerable weekly intake" (TWI) of ochratoxin A (on advice of the Scientific Panel on Contaminants in the Food Chain) at 120 ng/kg., equivalent to a tolerable daily intake (TDI) of 14 ng/kg. Other organizations have established even lower limits for intake of ochratoxin A, based on the consumption habits of the population. For USA, the FDA considers a TDI of 5 ng/kg. In the US, mean body weight for men is 86 kg, and for women 74 kg. Hence, the TDI for men is 430 ng and for women is 370 ng. In the joined table "weight in kg" is the weight eaten per day of each of the listed foodstuffs. Diet 1, with small quantities of ginger, nutmeg, and paprika, a good serving of dry raisins, a reasonable amount of coffee, cereals, wine, pulses, and salami, amounts to a safe diet (as for ochratoxin, at least), with 286 ng per day. However, it would be easy to go into excessive levels (Diet 1+), just by eating 200 g of pig kidney and 200 g of peanuts, which would lead to a total of nearly 462 ng of ochratoxin. This shows how delicate a safe diet can be.
