It’s very important to be able to improve the body’s immunity system against developing diseases by natural means – even more important considering that nowadays many medications and antibiotics are losing their efficaciousness.
Scientists believe that this line of research will lead to a better understanding of how diet and eating habits influence the immunity.
A new study by scientists at the University of Oregon showed that dark sorts of grapes and blueberry can be effective in it.
Resveratrol and pterostilbene are biologically active compounds that are found in grape skin, wine and blueberry. These antioxidants lower the risk of development of tumors, heart diseases, alleviate different inflammations, bring down the cholesterol and sugar levels in the blood, protect from the development of dementia. They are effective against a wide range of bacteria, fungi and viruses.
It emerged from laboratory research that both these antioxidant compounds, working in conjunction with vitamin D, boost up significantly the expression of cathelicidin, an antimicrobial peptide of nonspecific protection which is responsible for immunity.
