The assimilation amount of human body is between10% and 20% (that is, it can only absorb 10%~20%), and normal people need 1000~2000Kj of energy every day.
If only calculated by energy, at least 500g per day can meet the minimum requirements (assuming assimilation of 20%, you only need 1000Kj, which is not the case).
1 mol protein can generate about 39Kj of energy, and protein is the substance that constitutes the human body.
Fat provides more energy and is the energy storage material of human body.
Carbohydrates are mostly sugars, which are the main energy-supplying substances.
But these are already included.
It is worth noting that it is definitely no problem to eat only biscuits in the short term, but it will not work in the long term.
Protein is divided into plant protein and animal protein.
Some people can synthesize protein, and some people can't synthesize protein, so they must rely on external protein.
Usually cookies can't provide all the protein, and there will be problems in body function.
There are also some trace elements, although few, which are necessary for human body, such as iron, zinc, copper, manganese, chromium, selenium, molybdenum, cobalt and fluorine, which biscuits cannot provide.
In short, short-term emergency can be done, and there must be problems in the long run!
