The nutrients that do not need to be digested they have to be smaller than the cells of the small intestine. Some of these are sugars and amino acids.

Because the human body cannot absorb nutrients from foods, without breaking them down into smaller parts.
What molecule can diffuse from the digestive tract into the human blood stream without first being digested?
Water, oxygen, and carbon dioxide can enter or leave a cell by diffusion without being digested.
What would happen if there was no villi in humans body?
The villi vastly increase the effective surface area of the small intestine, allowing nutrients to be rapidly absorbed. Without them, the process would take longer, perhaps prohibitively longer. If the reduction in surface meant slower motion of the food, it might become necessary to eat more frequently to provide the same nutrients, and this would also mean more food bulk within the intestines at any given time. This can already be observed in individuals who have lost part of their digestive systems to injury or disease, and have to adjust their type of food intake (predigested) or limit their activities because insufficient calories are absorbed in the jejunum.
Do minerals need to be digested?
When we take food inside the body ,many mechanism starts.The process is known as food absorption.Most of the food is absorbed through Passive absorption without the expenditure of energy.But mineral and vitamin get absorbed through carrier mediated transport .In carrier mediated transport in the cell membrane in having limited no. of carriers which attaches itself to the vitamins and transport it to other side of the cell membrane i.e.blood
What is the function of villi?
The villi are folds within the lumen of small intestine walls. The whole purpose of villi is to increase the amount of surface area to be able to absorb more nutrients. Without villi, food would pass too easily through the digestive system causing you to defecate (poop) more. And you wouldn't get as much nutrition our of the food that you do eat so you'd have to eat more as well.

What nutrients can be absorbed in your body without undergoing digestion?
Well I don't know about nutrients but drugs that are present in smoke are absorbed without digestion while the THC in mull cookies have to be digested before there are any effects on the human body. This leads me to make the assumption that in order to absorb nutrients from your meals without having to digest it you should smoke your meals from either a bong or a rolled up joint. In order to get the most efficient amount of nutrients from the meal id suggest you should try using a bong.

Does glucose need to be digested before it is absorbed?
Glucose is a monosaccharide, so it does not need to be broken down any further. It can be absorbed without any changes.
Can triglycerides be absorbed without being digested?
No . A molecule of triglyceride is composed of a molecule of glycerol in ... Triglyceridescannot be efficiently absorbed, and are enzymatically digested by pancreatic lipase into a 2-monoglyceride and 2 Free fatty acids. All of which can be absorbed. Other lipase's hydrolyse a triglyceride into glycerol and 3 fatty acids.

Can dietary fiber be absorbed in the small intestine?
No, your body cannot digest fiber. Fiber is a special type of carbohydrate that passes through the human digestive system virtually unchanged, without being broken down into nutrients.
Does water absorb into the body without needing to be digested?
