N-3 FATTY ACIDS:

  • Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA)
  • Long chain n-3 fatty acids (EPA and DHA) important for development and maintenance of the brain, eyes, cell membranes, pregnancy and cardiovascular diseases.α-linolenic acid (ALA) is converted to EPA and DHA in the body. Men should get 1.6 grams/day and women should get 1.1 grams/day of ALA.
  • α-linolenic acid (ALA) is converted to EPA and DHA in the body. Men should get 1.6 grams/day and women should get 1.1 grams/day of ALA.The best plant sources of ALA are: flax seeds, chia seeds, camelina seeds, canola seeds, hemp seeds, walnuts and their oils
  • The best plant sources of ALA are: flax seeds, chia seeds, camelina seeds, canola seeds, hemp seeds, walnuts and their oilsNote: high intakes of linoleic acid (vegetable oils, safflower oils) may reduce the conversion of ALA to EPA and DHA.

IRON:

  • Vegetarians generally consume as much or slightly more iron than omnivores.
  • Iron stores of vegetarians are less than nonvegetarians.-Elevated iron stores (high ferritin levels) independently associated with risk of metabolic syndrome.
  • Elevated iron stores (high ferritin levels) independently associated with risk of metabolic syndrome.-Absorption of non-heme iron from plant foods depends on the body’s need and regulated partially by the body’s iron stores.

  1. Thank you dr Sean!! You make nutrition ever so easy to understand. There is so much more we want to know i.e. what exactly is a plant based diet? How does one stick to something past a 21 day challenge? Can we have a quick tip at the end of every video with a small cool change we can make today?
    Thanks!!!
