Question

As compared to the original DRIs from the 1940s, the current DRIs now consider levels associated with chronic disease risk reduction, no longer include recommendations for those vitamins for whom deficiency diseases are no longer a problem, include recommendations for three macronutrients and eight micronutrients, and are only expressed as average daily minimums rather than the more generous values in the original?

1) now consider levels associated with chronic disease risk reduction
2) No longer include recommendations for those vitamins for whom deficiency diseases are no longer a problem
3) Include recommendations for three macronutrients and eight micronutrients
4) now are only expressed as average daily minimums rather than the more generous values in the original

Answer 1

The current DRIs have several key differences compared to the original DRIs from the 1940s, including the consideration of levels associated with chronic disease risk reduction, the exclusion of recommendations for vitamins no longer associated with deficiency diseases, the inclusion of recommendations for three macronutrients and eight micronutrients, and the expression of recommendations as average daily minimums.

Step-by-step explanation:

The question is asking about the changes in the current Dietary Reference Intakes (DRIs) compared to the original DRIs from the 1940s.

1) Now consider levels associated with chronic disease risk reduction:

The current DRIs take into account the levels of nutrients that have been linked to reducing the risk of chronic diseases like heart disease and cancer. This is an important addition to the original DRIs, as it recognizes the role of nutrition in preventing long-term health issues.

2) No longer include recommendations for those vitamins for whom deficiency diseases are no longer a problem:

The current DRIs no longer provide specific recommendations for vitamins that are no longer associated with deficiency diseases. This is because these deficiencies are no longer a major concern due to improved nutrition and access to a variety of foods.

3) Include recommendations for three macronutrients and eight micronutrients:

The current DRIs provide recommendations for three macronutrients (carbohydrates, proteins, and fats) and eight micronutrients (vitamins and minerals) necessary for maintaining health and preventing deficiencies. These recommendations help individuals meet their nutritional needs and support overall well-being.

4) Now are only expressed as average daily minimums rather than the more generous values in the original:

The current DRIs express nutrient recommendations as average daily minimums, which means they provide guidance on the minimum amounts needed to prevent deficiencies. In contrast, the original DRIs had more generous values, which were not solely focused on preventing deficiencies.
