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.
The dietary guidelines recommend getting between 25 and 38 grams of fiber a day and .8 grams of protein per kilogram of body weight a day. (That would mean a woman weighing 140 pounds who lives a ...
A 1995 research team's recommendation for children is that intake should equal age in years plus 5 g/day (e.g., a 4-year-old should consume 9 g/day). [94] [95] The NAM's current recommendation for children is 19 g/day for age 1–3 years and 25 g/day for age 4–8 years. [2] No guidelines have yet been established for the elderly or very ill.
Drinking 1- 2 L of water every day can prevent some uncomfortable symptoms by making the stool soft and bulky. The risk of intestinal obstruction from insoluble fiber in susceptible individuals, [26] fluid imbalance leading to dehydration and mineral deficiencies may increase if more than 50 g of fibre is ingested per day. For this reason ...

In this calculation, the CO 2 and O 2 must be given in the same units, and in quantities proportional to the number of molecules. Acceptable inputs would be either moles, or else volumes of gas at standard temperature and pressure. Many metabolized substances are compounds containing only the elements carbon, hydrogen, and oxygen.
Some organisms have instead anaerobic respiration, which extracts energy from food by reactions that do not require oxygen. The energy contents of a given mass of food is usually expressed in the metric (SI) unit of energy, the joule (J), and its multiple the kilojoule (kJ); or in the traditional unit of heat energy, the calorie (cal).
