From acne to ageing, wrinkles to blemishes, sugar has a lot to answer for. Sugar and high GI (glycemic index) foods lead to a spike in insulin levels and this causes inflammation throughout our bodies. Sugar also binds to collagen making the skin stiff. The technical term for this is a process called glycation. It’s simple really: less sugar equals better skin – and the results can very often be seen in just a week.
Insulin spikes are linked to acne breakouts and can cause the skin to appear red and inflamed. This is because inflammation produces enzymes that break down collagen and elastin, resulting in sagging skin and wrinkles.
