Human nutrition
The protein requirement for each individual differs, as do opinions about whether and to what extent physically active people require more protein. The 2005 Recommended Dietary Allowances (RDA), aimed at the general healthy adult population, provide for an intake of 0.8 grams of protein per kilogram of body weight. A review panel stating that "no additional dietary protein is suggested for healthy adults undertaking resistance or endurance exercise."
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.
