THE GREAT DEBATE

October 15, 2022 Ravi Ramkissoon 0

”THE GREAT DEBATE”
Politics is not as controversial, as getting nutritionists to agree on vitamin supplementation. Remember, a multivitamin cannot replace a healthful well-balanced diet. The purpose of a multivitamin is to fill nutritional gaps .It provides only a hint of the vast array of healthful nutrients and chemicals naturally found in food. It cannot offer fiber, flavor or enjoyment of foods.

The key is an optimal diet. However, multivitamins can play an important role when nutritional needs are not met through diet. When this is the case, an expensive brand name is not necessary. Even standard store brands will deliver results. Look for one that contains the Recommended Daily Allowance amounts and one that bears a reputable seal of approval.
Eating a balanced diet may be difficult. We struggle with processed grains, hydrogenation, bleached flour, unfit growing conditions and canning, and freezing which reduce the vitamin and mineral content of food. Boiling food drains away much vitamins and minerals from food also.
If this were not enough we have to contend with environmental antagonists which affect our ability to absorb and utilize nutrients and increase the need for specific ones. Smoking, dieting, stress, pollution, medication, surgery, age and exercise are just a few.

Stay away from single vitamin mega doses as vitamins and minerals work synergistically, which means that they work with each other.

Dr. Deanna Minich in the following article titled : Vitamin and Mineral Interactions: The Complex Relationship of Essential Nutrients, published October 19th, 2018, shows why complete multi vitamins and minerals are the way to go when supplementing and the synergistic qualities of these micro nutrients.

Vitamin and Mineral Interactions: The Complex Relationship of Essential Nutrients

The essential vitamins and minerals share a delicate dance in the body. For many body processes to function optimally, you must have the right balance of the nutrients. Many nutrients work synergistically, so a deficiency in one might appear as or exacerbate a deficiency in another and vice versa.

Other nutrients are antagonists, so care must be taken when supplementing with one so it does not negatively impact the absorption, uptake, or metabolism of the other. For some nutrient pairs, the balance is delicate, with the pairs in certain situations enhancing the work of the other, and in other situations, they antagonize one another.

The following is a brief overview of the relationships and interactions between the essential nutrients. As you will see, some vitamins and minerals have a relationship with several other essential nutrients, while some have few if any known synergistic or antagonistic interactions.
