However, “using the glycaemic index to decide whether foods or combinations of foods are healthy can be misleading”, notes the NHS.
The health body explains: “Foods with a high GI are not necessarily unhealthy and not all foods with a low GI are healthy.
“For example, watermelon and parsnips are high GI foods, while chocolate cake has a lower GI value.”
It adds: “If you only eat foods with a low GI, your diet may be unbalanced and high in fat.”
