According to nutrition experts, purple sweet potato is one of the outstanding choices thanks to being rich in fiber and antioxidant compounds that are beneficial for weight control.
Purple sweet potatoes contain a lot of soluble fiber, which helps slow down the digestive process, create a feeling of fullness for a long time and limit cravings. In addition, this root has a relatively lower glycemic index compared to many refined starchy foods, contributing to limiting sudden blood sugar spikes after meals.
According to Dr. Lisa Young, a nutritionist, professor at the University of New York (USA) and author of many books on nutrition, sweet potatoes are a source of high-quality carbohydrates. When eaten with a reasonable diet, sweet potatoes provide sustainable energy, while supplementing fiber to help control hunger and support the weight loss process.
In addition to fiber, purple sweet potatoes are also rich in anthocyanins - a group of natural purple pigments with strong antioxidant abilities. Some studies show that anthocyanins can contribute to improving fat metabolism, reducing inflammatory reactions and supporting weight control when combined with a healthy diet.
However, experts note that sweet potatoes are not a "miracle food" to help lose weight. Efficiency is only achieved when combined with a balanced diet, controlling total calories and maintaining regular physical activity. People who lose weight should also prioritize boiled or steamed sweet potatoes instead of fried, grilled with a lot of butter, sugar or cheese to avoid increasing the energy of the meal.
Replacing a portion of refined starch with purple sweet potatoes, combined with green vegetables, lean protein and an active lifestyle will help the weight loss process take place safely and sustainably.
