10 reasons why seniors need more vitamin D has the following

  1. Senior skin produces 3X less Vitamin D for the same sun intensity
  2. Seniors have fewer vitamin D receptors as they age
  3. Seniors are indoors more than than when they were younger
    • not as agile, weaker muscles; frail, no longer enjoy hot temperatures
    • (if outside, stay in the shade), however, seniors might start outdoor activities like gardening, biking, etc.
  4. Seniors wear more clothing outdoors than when younger
    • Seniors also are told to fear skin cancer/wrinkles
  5. Seniors often take various drugs which reduce vitamin D
  6. Seniors often have one or more diseases which consume vitamin D
  7. Seniors generally put on weight at they age - and a heavier body requires more vitamin D
  8. Seniors often (40%) have fatty livers – which do not process vitamin D as well
  9. Reduced stomach acid ==>less Magnesium needed to utilize vitamin D
    (would not show up on vitamin D test)
  10. Seniors with poorly functioning kidneys do not process vitamin D as well
    (would not show up on vitamin D test) 2009 full text online  Also PDF 2009
  11. Vitamin D is not as bioavailable in senior digestive systems (Stomach acid or intestines?)

Items in both categories Seniors and Omega-3 are listed here:

several indexes are used to measure the quality of nutrition in advanced ages. None of them were designed to evaluate nutrition to avoid disabilities in elderly population.

to retrieve from literature "nutrients and intakes" showing to be involved in aging, and propose a new index, considering this information, to evaluate the quality of nutrition for preventing diseases related to aging.

a bibliographic review was performed, retrieving information on nutrients associated with aging. All these nutrients were incorporated into a new Healthy Aging Diet Index (HADI). Next, a cross-sectional study was carried out with two convenience samples of elderly, collecting the nutritional and dietary data, calculating different validated indexes and comparing them with HADI to validate the results.

forty-eight manuscripts were retrieved for full-text analysis. Associations were found between

cardiovascular diseases

  • macronutrients,
  • dietary fibre,
  • sodium and
  • vitamin D


  • fatty acids


  • fatty acids
  • fibre and
  • simple sugars;


  • calcium
  • vitamin D


  • proteins,
  • calcium
  • vitamin D

cognitive impairment

  • fatty acids
  • folates.

Sample 2, associated with rural areas, obtained lower indexes' scores. The behavior of HADI is similar to the other indexes (6.24/14 and 6.10/14 in samples 1 and 2, respectively).

the presented collection of nutrients adds useful evidence for the design of diets that allow healthy aging. The new index proposed is a tool of specific nutritional measurement in studies aimed to prevent diseases related to aging.
