Vitamin And Mineral Requirements In Human Nutrition Second Edition
Introduction
Vitamins and minerals are essential nutrients that our body requires for proper functioning. These nutrients are not produced by the body, so they must be obtained through the food we eat or supplements we take. The second edition of “Vitamin and Mineral Requirements in Human Nutrition” is an authoritative source of information for healthcare professionals, nutritionists, and dietitians.
What are Vitamins?
Vitamins are organic compounds that are required in small amounts to maintain good health. There are 13 essential vitamins that our body requires. These vitamins are divided into two categories: fat-soluble vitamins and water-soluble vitamins. Fat-soluble vitamins are stored in the liver and fatty tissues, while water-soluble vitamins are not stored in the body and are eliminated through urine.
What are Minerals?
Minerals are inorganic substances that are required in small amounts for proper body functioning. There are two types of minerals: macrominerals and trace minerals. Macrominerals are required in larger amounts, while trace minerals are required in smaller amounts.
Why are Vitamins and Minerals Important?
Vitamins and minerals play a vital role in maintaining good health. They are required for proper growth and development, maintaining healthy skin and eyes, producing energy, and strengthening the immune system. A deficiency in any of these nutrients can lead to various health problems.
