Li has been concerned within the subject of angiogenesis for greater than three a long time. In consequence, “I’ve been concerned with some breakthroughs in treating most cancers, blindness, and diabetes — in addition to meals as drugs, since what we eat might help our angiogenesis system keep wholesome,” says Li.
Finally, Li’s drive is a deal with prevention moderately than solely treating illness. It’s meals as a type of preventative drugs, he says. “Maintaining a healthy diet meals is one thing we will do for ourselves at house, below our personal management, based on our personal preferences, and between visits to the physician’s workplace,” provides Li. And, he says, your eating regimen can have a exceptional impact on most cancers prevention and therapy.
