Defining Powerhouse Fruits and Vegetables: A Nutrient Density Approach
Investigations aimed at detecting, identifying, and understanding the structure of marine natural products have led to the discovery of 20, new substances, including those characterized by an extremely high physiological activity. For more information see Tools or farmdoc. The measure of genetic diversity is 2pq which also is the frequency of heterozygosity in Hardy-Weinstein equilibrium. It is also important to achieve micronutrient diversity, not just a high level of a few isolated micronutrients. Krylova 1 , T.

Dr. Fuhrman’s Aggregate Nutrient Density Index (ANDI)

Aggregate Stability

Of 47 foods studied, all but 6 raspberry, tangerine, cranberry, garlic, onion, and blueberry satisfied the powerhouse criterion Table 2. Nutrient density scores ranged from The proposed classification scheme is offered in response to the call to better define PFV and may aid in strengthening the powerhouse message to the public. Messages might specify PFV to help consumers know what they are and choose them as part of their overall fruit and vegetable intake.

As numeric descriptors of the amount of beneficial nutrients PFV contain relative to the energy they provide, the scores can serve as a platform for educating people on the concept of nutrient density.

Expressing the nutrient desirability of foods in terms of the energy they provide may help focus consumers on their daily energy needs and getting the most nutrients from their foods. The rankings provide clarity on the nutrient quality of the different foods and may aid in the selection of more nutrient-dense items within the powerhouse group.

Foods within particular groups were studied; thus, other nutrient-dense items may have been overlooked. Because it was not possible to include phytochemical data in the calculation of nutrient density scores, the scores do not reflect all of the constituents that may confer health benefits. Warranting study is the utility of approaches defining PFV based on the presence regardless of amount of nutrients and phytochemicals.

Although nutrient density differences by powerhouse group were examined, a true validation of the classification scheme is needed. Future studies might identify healthful diets and examine correlations with PFV or look for correlations between intake of PFV and health outcomes 3. This study is an important step toward defining PFV and quantifying nutrient density differences among them.

On the basis of the qualifying nutrients, 41 PFV were identified. The included foods may aid in improving consumer understanding of PFV and the beneficial nutrients they provide. When a range of values was reported, the lowest value in the range was used as the weighting factor. The opinions expressed by authors contributing to this journal do not necessarily reflect the opinions of the U.
