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.
These are referred to as metamorphic proteins. [5] Finally other proteins appear not to adopt any stable conformation and are referred to as intrinsically disordered. [6] Proteins frequently contain two or more domains, each have a different fold separated by intrinsically disordered regions. These are referred to as multi-domain proteins.
As foods vary by brands and stores, the figures should only be considered estimates, with more exact figures often included on product labels. For precise details about vitamins and mineral contents, the USDA source can be used. [1] To use the tables, click on "show" or "hide" at the far right for each food category.
Tuna. This fatty fish serves up more than heart-healthy omega-3 fatty acids. A 3-ounce serving of raw tuna has 20 grams of protein, and one can of cooked tuna has a whopping 33 grams of protein.
Various foods. This is a categorically organized list of foods.Food is any substance consumed to provide nutritional support for the body. [1] It is produced either by plants, animals, or fungi, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, and minerals.
Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g). [2] Water makes up a large proportion of the total mass ingested as part of a normal diet but it does not provide any nutritional value.
Display of various foods. Food is any substance consumed by an organism for nutritional support. Food is usually of plant, animal, or fungal origin and contains essential nutrients such as carbohydrates, fats, proteins, vitamins, or minerals.
The total nitrogen content of organic matter is mainly formed by the amino groups in proteins. The Total Kjeldahl Nitrogen is a measure of nitrogen widely used in the analysis of (waste) water, soil, food, feed and organic matter in general. As the name suggests, the Kjeldahl method is applied. More sensitive methods are available.
