Red grapes, blueberries may enhance immune function Science Daily
- “Both of these compounds (resveratrol and pterostilbene), which are called stilbenoids, worked in synergy with vitamin D and had a significant impact in raising the expression of the human cathelicidin antimicrobial peptide, or CAMP gene, that is involved in immune function.”
- It is well known that more vitamin D getting to cells increases the immune system.
- “Stilbenoids are compounds produced by plants to fight infections, and in human biology appear to affect some of the signaling pathways that allow vitamin D to do its job, researchers said. It appears that combining these compounds with vitamin D has considerably more biological impact than any of them would separately”
Note: there is some indication that applying pesticides to grapes/blueberries reduces the amount of stilbenoids which they produce – the plants no longer need them. For that reason I try to only use organic grapes and blueberries.
