Difference Between Fat Soluble and Water Soluble Vitamins

what is the difference between fat-soluble and water-solubleA vitamin is an organic molecule that the body needs to grow and develop. It is a micronutrient, mainly obtained through food because it cannot be synthesized in the organism.

Many vitamins are also classified as water- and fat-soluble vitamins. Read on to learn the difference between the two.

What are Fat-Soluble Vitamins?

As the name suggests, fat-soluble vitamins are vitamins that are fat-soluble. The fatty tissue in the human body absorbs these vitamins, which are then retained through the blood.

Fat-soluble vitamins are found in large quantities in egg yolks, fatty fish, dairy products, beef, etc. Excess fat-soluble vitamins are stored in adipose tissue or liver, which are then absorbed by the body.

What are Water-Soluble Vitamins?

Water soluble vitamins are the opposite of fat soluble vitamins and these vitamins are water soluble. Folate, niacin, thiamin, pantothenic acid, vitamins B6 and B12, riboflavin and vitamin C fall under water-soluble vitamins.

Unlike fat-soluble vitamins, they are not stored in the body, so the human body needs a continuous supply of water-soluble vitamins, because excess useless water-soluble vitamins are excreted in the urine.

Water-soluble vitamins are found mostly in fruits, grains and vegetables, Ate. and these vitamins are vulnerable to heat, so they can also be destroyed by the heat of cooking during cooking.

The human body requires many water- and fat-soluble vitamins for proper metabolism. Since fat-soluble vitamins are stored in the human body, they do not need to be regularly consumed, however, water-soluble vitamins are not stored in the body, so they must be taken regularly and excessive consumption of these vitamins can lead to many serious heart diseases.

however, water-soluble vitamins are less toxic than fat-soluble vitamins. So, it’s important to eat a healthy diet with plenty of these nutrients.
