Biography

Jenkins obtained a PhD from Oxford University in 1975.^[6] He is a Fellow of the Royal College of Physicians and Surgeons of Canada.^[6]

Jenkins is credited with developing the concept of the glycemic index as a way of explaining the way in which dietary carbohydrate impacts blood sugar.^[7] His first paper on the subject appeared in the American Journal of Clinical Nutrition in 1981.^[8] Jenkins went on to author at least 15 more clinical studies on the effects of the glycemic index.

Portfolio diet

More recently his focus has shifted to optimising serum lipids rather than glycemic index, culminating in a diet he calls the Portfolio diet that prioritises whole plant foods such as nuts, soy, healthy fats, plant sterols and soluble fibre.^{[3] [9]} He has run clinically based dietary trials to elucidate the potential of the diet to prevent and treat chronic diseases such as cardiovascular disease.^[10]
