White rice is high on the glycemic index chart because it’s fast absorbed in the body. It breaks down rather quickly in the body, which instantly spikes insulin. The problem here for you is that it subsequently also leads to release of testosterone, which also causes your oil glands to go on an overdrive. But this is not to say that you should avoid it completely. Practice portion control and try mixing rice with a high protein food to balance things out.
White bread has a glycemic index of 70—which means the number of pizzas and sandwiches you’ve had could well be the reason behind your severe acne concerns. Worse, breads also contain sugar, which instantly causes your insulin levels to spike up. So it’s about time you looked into your diet and cut down on white bread, stat!
White potatoes are knows to be unhealthy. They are the carbs that quickly get converted into sugar. This is why in addition to acne, you also run the risk of diabetes and heart diseases. But being smart while eating potatoes makes all the difference. What you essentially need to do is reduce the glycemic index of potatoes by consuming them with fats or proteins that will make the digestion slower compared to eating them by themselves.
They’re low on protein and high on the glycemic index, which means if someone is telling you to eat cornflakes for weight loss, it’s going to be of little value. Worse, many kinds of cornflakes often contain HFCS (High Fructose Corn Syrup), which is an added sugar. And sugars are an absolute no-no for skin.
It is no surprise that soda is a part of the list since it contains copious amounts of sugar that instantly raises your blood sugar. Unlike other high glycemic foods, which can be balanced out by consuming them with high fat or high protein foods, soda is absolutely harmful for the body, especially your skin.
