Quinoa is high in Protein and Stimulates Protein Synthesis from WODMASTERS

I’m not sure where Quinoa falls on the dietary good-evil spectrum these days.  Many value it for its high protein and mineral content.  It can be a staple food for the health-minded vegetarian.  On the other side of the spectrum, Quinoa has been on the do-not-eat list for followers of the Paleo diet because advocates consider it to be a grain.  Paleo dieters have also been concerned that Quinoa contains saponins. Some have proposed that saponins may damage the intestines.  However saponins are beneficial anti-oxidants and some are health-protective.  For a more general discussion of Quinoa and why it should be an excellent addition to the paleo diet click here.

Quinoa is high in protein, flavonoids and phytoecdysteroids

Analysis of quinoa extract shows that quinoa contains:

  • 20% protein
  • 11% oil
  • 2.6% flavonoid glycosides
  • 1% phytoecdysteroids (this is very high compared to other plants)

Protein, as we all know, is important for building strength and muscle mass.  Protein is also important in preserving muscle mass and functionality in older people.  Protein intake may be important to long-term health.  Its not just an issue for athletes and body-builders. Flavonoid glycosides are health protective anti-oxidants.   Quinoa contains high amounts of phytoecdysteroids.   These are thought to be part of a plants phytoecdysteroids.  However, they may be good for people.  There are many different phytoecdysteroids. The dominant phytoecdysteroid in quinoa is 20HE.

Beneficial effects of phytoecdysteroids

There have been a number of studies showing different positive effects of phytoecdysteroids or of qunoia extract.

  • Quinoa extract lowered blood glucose in obese, hyperglycemic mice
  • Phytoecdysteroids increased protein synthesis in animals with and without exercise
  • 20HE (the predominant phytoecdysteroid in quinoa) has anabolic-like properties that promote protein synthesis
  • 20HE Increased muscle fiber size
  • Phytoecdysteroids Inhibited tumor growth
  • Quinoa extract increased metabolic rate and may be an anti-obesogen

How phytoecdysteroids work is not completely understood.  They do not seem to act in the same way as anabolic steroids.  So far, phytoecdysteroids show very low toxicity in mammals but limited (if any) testing has been done in humans.
