(Natural News) This observational study was conducted by European researchers to describe the current micronutrient intakes of Dutch elderly and to identify the contribution of nutrient-dense foods, fortified foods, and dietary supplements to the intake of micronutrients that are often inadequately consumed in Dutch elderly. Their findings were published in the journal Nutrition Research.

  • As people age, they require a more nutrient-dense diet to meet their nutritional needs.
  • The use of nutrient-dense foods, fortified foods, and dietary supplements can be important.
  • To determine if the micronutrient intake of Dutch elderly is adequate, the researchers analyzed data from 245 Dutch volunteers aged 65 to 80 who were involved in the NU-AGE study.
  • The researchers assessed the volunteers’ dietary intake by means of 7-day food records, and their use of dietary supplement was recorded with an additional questionnaire.
  • The researchers obtained information on fortified foods from the Dutch Food Composition Table 2011.
  • They evaluated the nutrient density of foods using the Nutrient Rich Food 9.3 score.
  • Based on conventional foods intake, the researchers gathered the following data:
    • 99 percent were deficient in vitamin D
    • 41 percent were deficient in selenium
    • 54 percent were deficient in vitamin B6
  • When consumption of fortified foods was taken into account:
    • 98 percent were deficient in vitamin D
    • 41 percent were deficient in selenium
    • 27 percent were deficient in vitamin B6
  • When vitamin and mineral supplements were taken into account:
    • 87 percent were deficient in vitamin D
    • 36 percent were deficient in selenium
    • 20 percent were deficient in vitamin B6
  • Conventional foods were the main source of vitamin D, vitamin B6, and selenium intake, followed by vitamin and mineral supplements and fortified foods.
  • Foods with the highest nutrient density contributed most to total vitamin B6 intake only.
  • The nutrient intake of Dutch elderly, particularly vitamin D, is inadequate, and their intakes of vitamin B6 and selenium are concerning.

Based on these findings, the researchers concluded that a combination of natural food sources, fortified foods, and dietary supplements is needed to optimize the nutrient intakes of Dutch elderly.
