Snacking on chilled fresh fruit is a refreshing way to beat the heat on the hottest of summer days. While taking advantage of spending time in the sun, nothing quite compares to biting into a perfectly ripened, juicy slice of watermelon at a picnic, beach, or backyard barbecue. But if you have <\/span>diabetes or prediabetes<\/span><\/a>, can you safely eat watermelon, with its natural sugar, or will the sugar content throw off your whole day? We went to the medical experts to find out.\u00a0<\/span><\/p>\n

Does watermelon raise blood sugar?<\/span><\/h2>\n

\u201cEating large quantities of any food with carbohydrates can potentially raise blood sugar levels,\u201d says Sara Chatfield, RDN, a Chicago-area registered dietitian<\/span>. \u201cWhile watermelon typically has a sweet taste, it\u2019s actually lower in sugar than many popular fruits due to its high water content.\u201d<\/span><\/p>\n

To understand exactly how watermelon will affect your blood sugar, we need to look at the glycemic index, sometimes referred to as GI. The glycemic index ranks food from 0 to 100 to indicate how much a certain food will increase blood sugar levels. Foods ranked at 0, like lean beef, are slowly digested and will not spike blood sugar. On the other end of the spectrum, pure sugar measures at 100 on the glycemic index and is not safe for people with diabetes outside of small, occasional amounts.\u00a0<\/span><\/p>\n

Watermelon has 17 grams of sugar per 280-gram serving and a 72 glycemic index rating, but that doesn\u2019t tell the whole story.<\/span><\/p>\n

It\u2019s also important to factor in the glycemic load (GL), which looks at how quickly your blood sugar will rise based on the <\/span>amount<\/span><\/i> you eat. To find the glycemic load, you multiply the glycemic index by the amount of carbohydrates in a serving size and then divide that number by 100. This gives a 280-gram serving of watermelon a glycemic load of 15, which is considered a medium GL.<\/span>

Can people with diabetes eat watermelon?<\/span><\/h2>\n

\u201cYes, individuals with diabetes can safely enjoy watermelon as part of a balanced diet,\u201d says <\/span>Stewart Parnacott<\/span><\/a>, CRNA, a nurse anesthetist in Atlanta. In addition to stressing that \u201cmoderation is key,\u201d he has a helpful tip for people with diabetes who want to eat watermelon responsibly: \u201cMonitoring portion sizes and pairing watermelon with protein or healthy fats can help manage blood sugar levels effectively.\u201d<\/span><\/p>\n

This means that those with Type 1 diabetes and Type 2 diabetes can eat watermelon safely as long as they\u2019re monitoring their portions and blood glucose levels. According to the Nutrition Labeling and Education Act (NLEA), a serving of watermelon is 280 grams, which is a little less than 2 cups, diced or balled. A one-cup serving of watermelon weighs in at about 152 grams. If you eat watermelon as a snack, try to add some nuts, eggs, or yogurt to your plate for protein and healthy fats. This combination can better level out your blood sugar than eating carbs alone.<\/span>
