An interesting paper published last month in the Journal of Nutrition has found that eating dark green leafy vegetables led to an increased response to omega 3 fatty acid supplementation in Americans of African ancestry.
The participants in the 6 week trial were given five 5g capsules daily of either concentrated fish oil or a corn/soybean placebo.
The low response group, i.e., those that did not react to the supplementation of the fish oil also tended to eat less vegetables, especially dark green vegetables.
The researchers suggest more work should be done “to determine if dietary dark-green vegetables or nutrients contained in these foods can enhance the efficacy of ω-3 fatty acid supplements”.
