Watermelon's sugar content and its implications for diabetes management: Essential dietary advice and nutritional insights
For people with diabetes, maintaining a balanced, nutritious diet is crucial, and the American Diabetes Association (ADA) recommends a diet high in fruits and vegetables. One such fruit that can be included in this diet is watermelon.
Watermelon, with a glycemic index (GI) ranging between 72 and 76, is considered a food with a high GI, meaning it can raise blood sugar levels quickly. However, due to its low carbohydrate content per serving, watermelon has a relatively low glycemic load (GL), making it a viable option for those with diabetes. For instance, a cup of watermelon (about 154 grams) contains approximately 11.6 grams of carbohydrates, leading to a GL of around 5.6 to 8.35.
When compared to watermelon juice, several factors come into play. Juice generally has a higher carbohydrate concentration per serving, which means it can have a higher GL. Watermelon juice, being mostly water and sugars, would likely have a higher GL compared to whole watermelon due to its higher sugar and carbohydrate content per serving. Although specific GL values for watermelon juice are not provided, it is reasonable to assume the GL would be higher due to the absence of fiber and the concentrated sugar content.
For diabetic individuals, it is generally advisable to opt for whole fruits like watermelon over juices, as whole fruits provide fiber, which can help slow the digestion and absorption of sugars, thereby minimizing spikes in blood sugar levels. Watermelon juice, while refreshing, should be consumed in moderation due to its potential for higher GL and thus greater impact on blood sugar levels.
Watermelon offers other health benefits as well. A wedge of watermelon provides around 30% of the recommended daily vitamin C intake for females and 22% for males. It also contains 286 milligrams (mg) of potassium, which can help regulate blood pressure.
The GI of watermelon can be lowered by pairing it with nutritious fats and proteins, such as nuts, seeds, and other sources of healthy fat. Consuming watermelon with other foods rich in protein and fat can help slow the absorption of sugar into the bloodstream.
The ADA advises that certain fruits may affect people's blood glucose differently and recommends focusing on the totality of the foods and beverages a person consumes. A medium-sized slice of watermelon (286 g) contains approximately 12 g of sugar.
In addition to watermelon, the ADA advises consuming fruits such as oranges, berries, grapefruit, apples, peaches, kiwi, pears, avocados, cherries, and more. People with diabetes should monitor their fruit intake and choose fruits with lower sugar levels and higher amounts of fiber. It is also important to avoid pairing watermelon with other high GI foods.
Watermelon contains the nonessential amino acid citrulline, which may help improve blood pressure and metabolic health. One wedge of watermelon provides approximately 80 micrograms (mcg) of retinol activity equivalents (RAE) of vitamin A.
In conclusion, while watermelon has a high GI, its relatively low GL makes it a suitable choice for people with diabetes. It is best to eat watermelon without added sugars and in its whole and minimally processed form. For optimal management of blood sugar levels, it is advisable to pair watermelon with foods rich in healthy fats, fiber, and protein.
