Below is a list organised by food group and given in measurements of grams of protein per 100 grams of food portion. The reduction of water content has the greatest effect of increasing protein as a proportion of the overall mass of the food in question. Not all protein is equally digestible.
Included for each food is its weight in grams, its calories, and (also in grams,) the amount of protein, carbohydrates, dietary fiber, fat, and saturated fat. [1] As foods vary by brands and stores, the figures should only be considered estimates, with more exact figures often included on product labels.
Chicken Breast. 4 ounces cooked boneless skinless chicken breast: 33 grams of protein
[36] [37] When looking at meat only, ruminants consume an average of 2.8 kg of human edible feed per kg of meat produced, while monogastrics need 3.2 kg. [36] [37] Finally, when accounting for the protein content of the feed, ruminant need an average of 0.6 kg of edible plant protein to produce 1 kg of animal protein while monogastric need 2 kg.
[citation needed] 100 grams (3.5 oz) of raw chicken breast contains 2 grams (0.071 oz) of fat and 22 grams (0.78 oz) of protein, compared to 9 grams (0.32 oz) of fat and 20 grams (0.71 oz) of protein for the same portion of raw beef flank steak.
The nutrient or mineral content of foods, animal feeds or plant tissues are often expressed on a dry matter basis, i.e. as a proportion of the total dry matter in the material. For example, a 138-gram apple contains 84% water (116 g water and 22 g dry matter per apple). [5]
The foodstuffs listed for comparison show the essential amino acid content per unit of the total protein of the food, 100g of spinach, for example, only contains 2.9g of protein (6% Daily Value), and of that protein 1.36% is tryptophan.

Dehydrated meat stock, in the form of tablets, was known in the 17th century to English food writer Anne Blencowe, who died in 1718, [1] and elsewhere as early as 1735. [2] Various French cooks in the early 19th century (Lefesse, Massué, and Martin) tried to patent bouillon cubes and tablets, but were turned down for lack of originality. [ 3 ]
