Can you realistically get all the nutrients you need from food?

It’s not an issue of food quantity but rather food quality. Even a low-calorie diet can deliver all the vitamins and minerals you need with one exception—vitamin D. So plan to take a vitamin D supplement. Getting the rest of your nutrients through diet requires some planning and some knowledge about food.

Is it possible to get all daily nutrients?

The answer is a qualified yes – we can do without them, as long as you eat a well-balanced diet rich in fruits and vegetables. In the past, doctors often suggested a standard multivitamin with minerals each day. They don’t cost much, and earlier studies had shown some benefits.

How is RDA determined?

The RDA is set at the EAR plus twice the standard deviation (SD) if known (RDA = EAR + 2 SD); if data about variability in requirements are insufficient to calculate an SD, a coefficient of variation for the EAR of 10 percent is ordinarily assumed (RDA = 1.2 x EAR).

What is the only way to get all the nutrients we need?

Eating a healthy, balanced diet is the best way to get all the nutrients the body needs.

WHO recommended RDA?

The recommended dietary allowance (RDA) is 0.5mg per 1000kcal….Dietary Reference Intakes.

Category	Age	RDA (μg day−1)

Children	4–6 years	200
	7–14 years	300
Adults	15+years	400

What is RDA in food?

Recommended Dietary Allowance (RDA): average daily level of intake sufficient to meet the nutrient requirements of nearly all (97\%-98\%) healthy people.

Is the RDA accurate?

The risk, but not the certainty, of inadequacy increases as intakes fall further and further below the RDA. However, the RDA is an overly generous criterion for evaluating nutrient adequacy. By definition, the RDA exceeds the actual requirements of all but about 2–3\% of the population.
