Snips about SNPs: Omega-3’s from plants

Omega-3 fatty acids are good for you in several ways, but one big thing we gain from omega 3’s is DHA and EPA for brain health. These two fatty acids have links to lower heart disease and better brains.

The body can convert plant-based omega 3’s from flaxseed and chia seeds into DHA and EPA. But for some people, this conversion process is extremely limited. Instead, they may need to get DHA and EPA directly through fish or algal oil.

  • T/T: low FADS1 enzyme activity; decreased risk of coronary artery disease due to lower arachidonic acid; benefits more from EPA/DHA intake for lower triglycerides[ref][ref][ref][ref]
  • C/T: lower FADS1 enzyme activity, decreased risk of coronary artery disease, may benefit more from EPA/DHA intake for lowering high triglycerides
  • C/C: typical FADS1 activity

*SNP stands for Single Nucleotide Polymorphism, which is when one of the nucleotide bases (the A, C, G, or Ts) is replaced by a different nucleotide base in a gene.
