do all foods require digestion?why or why not?

Answer 1

Sugar does not need digestion. But for example proteins do. It is broken into aminoacids first and those aminoacids are used in protein synthesis. There are millions of different proteins, human body may not need the protein it is having, but there are only 20-something aminoacids, we use almost all of them.
When it comes to vitamins and minerals, they are not digested they are absorbed in the intestines.
I hope this helped.

Answer 2

No...some food that we take in our body doesn't get digested by our system. An example of this are some seeds or small bones or any small items(like buttons or something). When you these in they just pass through the body but end up in our feces the same way it came in exept its dirty now! Edible food need to be digested to break it down into simpler substances that our body can absorb. It is broken down into simpler forms because some cells can only absorb it in the simplest form.

Answer 3

It is commonly believed that the human stomach should be able to digest any number of different foods at the same time. However, digestion is governed by physiological chemistry. It is not what we eat that is crucial to our health, but what we digest and assimilate.

Digestive enzymes
Digestive enzymes are secreted in very specific amounts and at very specific times. Different food types require different digestive secretions. Carbohydrate foods require carbohydrate-splitting enzymes, whereas protein foods require protein splitting enzymes, etc. It is the knowledge of the digestive process that has led many health practitioners to promote efficient food combing, the rules of which are briefly explained below:

1. Carbohydrate foods and acid foods should not be eaten at the same meal. Do not eat bread, rice or potatoes with lemons, limes, oranges, grapefruits, pineapples, tomatoes or other sour fruits. This is because the enzyme, ptyalin, acts only in an alkaline medium; it is destroyed even by a mild acid! Fruit acids not only prevent carbohydrate digestion, but they also produce a fermentation. Oxalic acid, for example, diluted to one part in 10,000 completely arrests the action of ptyalin. And, there is enough acetic acid in one teaspoon of wine vinegar to completely halt salivary digestion. Dr Percy Howe of Harvard Medical School states:

"Many people who cannot eat oranges at a meal derive great benefit from eating them fifteen to thirty minutes before the meal". Herbert Sheldon, author of 'The science and fine art of food and nutrition' reports: " I have put hundreds of patients , who have told me that they could not eat oranges or grapefruit, upon a diet of these fruits and they found that they could take them. Such people are in the habit of taking these foods with a breakfast of cereal, with cream and sugar, egg on toast, stewed prunes and coffee, or some similar meal."

Tomatoes should also never be combined with starchy food as the combination of the various acids in the tomato, which are intensified on cooking, are very much opposed to the alkaline digestion of starches. They may be eaten with leafy vegetables and fat foods.

Answer 4

foods are made of nutrients mainly carbohydrates, proteins,fats and vitamins.
nutrients can only be absorbed by the small intestine if they are in their simplest form AND are water soluble.
The simplest form of proteins is amino acids, carbohydrate is glucose and fats is glycerol and fatty acids.
So foods are digested to break them in their simplest form so they can be absorbed in the small intestine

Answer 5

to get energy the food has to be digested and broken into energy giving acid

Answer 6

according to me expect water every thing needs digestion !!!!!!!!!! so digest this
