Vitamins and minerals are both essential for a healthy body. However, they differ in their chemical composition, biological function and nutritional requirements.
Contents: Minerals vs Vitamins
edit Differences in Chemical composition
Vitamins are organic compounds while minerals are inorganic. Minerals have a much simpler chemical composition compared to vitamins. While vitamins are obtained from plants and animals, the body gets minerals from soil and water.
edit Types of Vitamins and Minerals
Vitamins can be water soluble or fat-soluble. While water-soluble vitamins are not stored in the body and have to be taken with water, fat-soluble vitamins get dissolved in the body’s fat cells and are also stored in the body.
Minerals are divided into macro minerals and trace minerals. Trace minerals are needed by the body in small quantities while macro minerals are needed in large amounts.
edit Nutritional Requirements
While all vitamins (A, B, C, D, E and K) are needed for the body, all minerals are not needed. Some of the necessary minerals are calcium, magnesium, zinc, iodine, sodium, copper, chromium, iron, sulphur, manganese, potassium and phosphorus.
Vitamins are easily destroyed while cooking due to heat or chemical agents. Therefore extra attention is needed while preparing food or storing it. Minerals on the other hand are not vulnerable to heat chemical reactions or sunlight. While vitamins are destructible, minerals are indestructible.
edit Biological Role
Vitamins release energy from the food, develop red blood cells, help in blood clotting and help in maintaining healthy skin, eye, and hair. On the other hand, minerals help in bone and tooth formation, blood coagulation, muscle contraction and also in keeping acid-alkaline balance in blood.
edit Health Benefits and Risks
The scientific evidence for popular health supplements is well-documented here.
Study after study has shown that taking multivitamins does not help improve health. In fact, several studies have shown that vitamin pills may actually increase the risk of certain diseases like cancer. The Atlantic published an excerpt from a book titled Do You Believe in Magic?: The Sense and Nonsense of Alternative Medicine that outlines several such studies.
On October 10, 2011, researchers from the University of Minnesota evaluated 39,000 older women and found that those who took supplemental multivitamins, magnesium, zinc, copper, and iron died at rates higher than those who didn't. They concluded, "Based on existing evidence, we see little justification for the general and widespread use of dietary supplements."
Two days later, on October 12, researchers from the Cleveland Clinic published the results of a study of 36,000 men who took vitamin E, selenium, both, or neither. They found that those receiving vitamin E had a 17 percent greater risk of prostate cancer.
In 2008, a review of all existing studies involving more than 230,000 people who did or did not receive supplemental antioxidants found that vitamins increased the risk of cancer and heart disease.
In 2007, researchers from the National Cancer Institute examined 11,000 men who did or didn't take multivitamins. Those who took multivitamins were twice as likely to die from advanced prostate cancer.
In 2005, researchers from Johns Hopkins School of Medicine evaluated nineteen studies involving more than 136,000 people and found an increased risk of death associated with supplemental vitamin E.
