Glycemic Index Diet Has More Benefits Than You Think

Glycemic Index Diet Has More Benefits Than You Think

Sweet potatoes have more sugar and around the same number of calories as russet potatoes. So why are sweet potatoes marketed as the healthier option? The answer is glycemic index (GI).


Foods like russet potatoes, white rice and flour, and oatmeal are often exiled by the health-conscious because of their high glycemic index. The term is thrown around on every fitness blog and forum, but what does it actually mean?


What is glycemic index?

Glycemic index is a measurement of how much a carbohydrate-rich food spikes your blood glucose (sugar) level. It also measures how fast glucose is released in your body. The greater the GI, the greater the spike. According to Healthline, “chronic high blood sugar increases the likelihood of serious diabetes complications like heart disease, blindness, neuropathy, and kidney failure.”


Therefore, it’s important to incorporate more low GI foods into a healthy diet. But that doesn’t mean cutting out carbohydrates altogether, since your body prefers glucose for energy. It just means being aware of the inconspicuous effects certain foods have on your body. When created, The low-GI diet was intended for diabetics. However, several other communities have adopted the lifestyle. It’s proven successful in managing blood sugar in Type 2 diabetics, according to Diabetes UK.  


Why follow a low glycemic index diet?

Eating low glycemic foods can benefit anyone, not just diabetics. Unless you’re keto, carbohydrates are likely a major part of your diet. When choosing which carbohydrates to fuel yourself with, look at glycemic index databases online to find information beyond the nutrition label.


Some popular benefits of the diet are weight loss and maintenance. Not only do low GI foods regulate blood sugar, but they metabolize slower. Not only do insulin spikes from high GI foods hurt your health in the long run, the make you hungry in the short run. Therefore, those spikes lead to more calories consumed, and more weight gained. Foods with low glycemic indexes usually fall under complex carbohydrates, which are carbs that take more time to become sugar in your body. Complex carbs don’t have the drastic effect that simple carbs (high GI foods) do.


Weight loss isn’t the only thing to gain from this popular diet. With a few simple swaps to your carbs, here are some other low GI benefits, according to the Glycemic Index Foundation:


  • Improve heart health
