Recommended Daily Intake

What is RDA?

RDA is the short form of Recommended Dietary Allowance. It is the amount of minimal nutrition a person need for a day to keep the body healthy. It is actually established in early 1900s to prevent deficiencies like pellagra, scurvy and rickets. RDA can be reached by healthy diet as recommended by our doctors. But it was in early 1900 and as we discussed previously the food they consumed compared to the current one differs in its nutritional value. And the diet is not enough for the current situation and so is the level of RDA needed for the day.

We need optimal level of nutrient to ward off the evil forces of degenerative diseases. As we all know through our trusted TV ads how many of each food items that we need to consume even to reach the level of nutrients provided by the supplements that are available in the supermarket shelf. So do the math to find out how much has to be consumed if we need to reach the optimal level of nutrient. That is practically impossible.

As Dr Ray Strand states:

“When you look at a wonderful wood fireplace it usually burns just fine. However, occasionally a spark or hot cinder shoots and burns a little hole in your carpet. Over the months and years, you will have a damaged carpet in front of your fireplace. Look at the fireplace as the furnace of your cell and the hot cinders as free radicals. Your carpet is your body. Whatever part of your body wears out first is the type of disease you will develop. Antioxidants are like the fine wire mesh or glass doors you place in front of your fireplace. The sparks are still going to fly; however, your carpet—your body—is protected. This is the key”

RDA’s versus Optimal Levels

One of the reasons most physicians do not recommend supplements for their patients, even though studies show that nearly 70% of physicians are taking them themselves, is because they have been taught that all we need are the Recommended Dietary Allowance (RDA) of micronutrients.   If you consume a healthy diet, it is certainly possible to get this level of nutrients.    However, you must understand the origin of RDA’s. These RDA’s  were developed in the late 1930’s and early 1940’s to establish the minimal amount of micronutrients required to prevent acute deficiency diseases like pellagra, scurvy, and rickets.

When I began studying about the possible health benefits of taking nutritional supplements, I was concerned about chronic degenerative diseases like heart disease, cancer, stroke, diabetes, Alzheimer’s dementia, and macular degeneration. What I quickly learned was that RDA’s have absolutely nothing to do with chronic degenerative diseases. For example, the RDA of vitamin E is 30 IU; however, you don’t begin to see a health benefit until you supplement with at least 100 IU of vitamin E. This health benefit increases as you increase the amount of vitamin E supplemented. Most researchers in nutritional medicine now believe that the optimal level of vitamin E is 400 IU.
