Summary

Dietary guidelines recommend increased carbohydrate intake, particularly from whole grains. Current consumption falls short, necessitating a significant increase in whole grain servings for Americans to meet recommendations.

Critical reviews in food science and nutrition·2014

Area of Science:

  • Nutrition Science
  • Dietary Recommendations

Background:

  • Current dietary guidelines recommend 55% of calories from carbohydrates, emphasizing complex carbohydrates.
  • There is confusion regarding the composition of complex carbohydrate foods and their health benefits.
  • Existing grain product intake is insufficient, with less than one whole-grain serving per day for adults.

Purpose of the Study:

  • To highlight the discrepancy between recommended and actual carbohydrate and whole-grain consumption.
  • To emphasize the need for increased intake of grain products, especially whole grains.

Main Methods:

  • Analysis of current dietary guidelines from the U.S. and Canada.
  • Evaluation of current adult grain product consumption patterns.
  • Comparison of recommended versus actual intake of total and whole grains.

Main Results:

  • Adults consume 4-5 servings of grain products, far below the recommended 5-12 servings.
  • Less than one serving of whole grains is consumed daily, despite recommendations for half of grain intake to be whole grain.
  • Significant increase needed in whole-grain (4-5 fold) and total grain (2 fold) consumption.

Conclusions:

  • Current dietary intake of grain products, particularly whole grains, is inadequate to meet established guidelines.
  • Increased consumption of whole grains is crucial for individuals to align with U.S. and Canadian dietary recommendations.
