Many vegetables have both soluble and insoluble dietary fiber, various sources of dietary fiber can inhibit the activity of pancreatic enzymes, reducing the digestive enzymes to the digestibility of protein, fat and carbohydrates in food.

At the same time, soluble dietary fiber, with strong water holding capacity, can form a viscous solution in the gastrointestinal tract, increasing the viscosity of the chowder, reducing the speed of gastric emptying, reducing the contact between digestive enzymes and chowder, and affecting the digestion and absorption of nutrients in the intestinal tract, which is equivalent to eating more and absorbing less. This is a feature that many people dream of in the process of losing weight.

The water-holding property of food fiber can make the intestinal coeliac viscosity increase, slowing down the transit of monosaccharides and neutral amino acids in the small intestine, which can improve glucose tolerance, and have a positive effect on weight loss for obese patients with high blood sugar and high blood fat in combination.

It should be reminded that vegetables, although nutritious, is not the more you eat the better. Dietary fiber in vegetables can affect the absorption of calcium, iron, zinc and other nutrients.
