Aunt Wu, at 56, was diagnosed with diabetes but has been proactive in managing her condition. She replaced her staple food with sweet potatoes after hearing they could help control blood sugar. However, she found her blood sugar levels dropped, leaving her confused about whether sweet potatoes truly help with diabetes.
Sweet Potatoes and Blood Sugar Control
Sweet potatoes are rich in starch, dietary fiber, vitamins, and minerals, offering good nutritional value. Their glycemic index (GI) varies with cooking methods. Raw sweet potatoes have a GI of 32, steamed or boiled have a GI of 63, and baked sweet potatoes have a high GI of 94. Therefore, the way sweet potatoes are consumed is crucial for diabetic patients. Proper consumption can help lower blood sugar, while improper consumption can raise it.
Guidelines for Diabetics Consuming Sweet Potatoes
Staple Food Replacement: Diabetics can include sweet potatoes in their diet as a replacement for other high-GI staples, ensuring to balance total daily calorie intake.
Reasonable Collocation: Sweet potatoes should be part of a balanced diet that includes vegetables, proteins, and whole grains to ensure dietary diversity.
Cool Before Eating: It’s recommended to cook sweet potatoes by steaming, bake them less often, and consume them after cooling to minimize their impact on blood sugar.
Sweet Potatoes and Cancer Prevention
Claims about sweet potatoes fighting cancer stem from Japanese research that found cooked sweet potatoes to have a high cancer cell inhibition rate. However, it’s important to note that these studies are based on cell and animal experiments, and the results cannot be directly applied to humans. The anticancer ingredients in food need to reach a certain dose to be effective, which is often not feasible through diet alone.
Nutritional Values of Different Sweet Potatoes
Sweet Potatoes: High in sugar and carotenoids, beneficial for preventing vitamin A deficiency and cardiovascular health, but high sugar content can affect blood sugar control.
Purple Potatoes: Rich in anthocyanins, which are antioxidants that protect against free radical damage and delay brain aging. They also promote gastrointestinal health.
White Potatoes: High in starch and less sweet, but excessive intake can still raise blood sugar due to their starch content.
conclusion
sweet potatoes can be part of a healthy diet for diabetics when consumed correctly. They are not a magical cure for high blood sugar or cancer, but a nutritious food that can contribute to a balanced diet. It’s essential to consider portion sizes, cooking methods, and the overall dietary balance.
