Sweet Potatoes
Also known as: sweet potato, sweetpotato, Ipomoea batatas
Overview
Sweet potatoes (*Ipomoea batatas*) are a globally consumed, nutrient-rich root vegetable known for their high carbohydrate content, vitamins, dietary fibers, and a variety of beneficial bioactive compounds. Commonly utilized in various culinary applications, they are also considered for their therapeutic properties, including weight management, glycaemic control, and enhancing athletic performance. Sweet potatoes contain key constituents like resin glycosides, which may inhibit pancreatic lipase activity and contribute to their antioxidant and anti-inflammatory profiles. While comprehensive research supports several health benefits, there remains a need for more robust clinical trials to confirm these claims.
Benefits
Sweet potatoes provide various evidence-based benefits. Notably, their extract has been demonstrated to promote weight management by reducing body weight gain and fat accumulation in high-fat diet scenarios due to the inhibition of pancreatic lipase (p < 0.05). Additionally, sweet potato preparations can improve glycaemic control, exemplified by a meta-analysis showing significant reductions in glycosylated haemoglobin A1c (HbA1c) levels in individuals with type 2 diabetes (mean difference -0.3%, P = 0.02). While benefits for athletic performance have been suggested due to their nutritional profile, the evidence is mostly observational. Furthermore, hepatoprotective effects have been observed in animal studies. Sweet potatoes are especially beneficial for individuals with type 2 diabetes and athletes, although more definitive human trials are required to establish these effects conclusively.
How it works
Sweet potato extract operates through several biological pathways, primarily by inhibiting pancreatic lipase, which decreases fat absorption and supports weight loss. Moreover, the anti-inflammatory and antioxidant properties of sweet potato compounds may improve insulin sensitivity and reduce liver fat accumulation, thereby aiding in glycaemic control and overall liver health. Key molecular interactions involve targeting pancreatic lipase and the regulation of nuclear factor kappa B, which is critical in inflammatory responses.
Side effects
Sweet potatoes and their extracts are generally regarded as safe for consumption. No common side effects have been recorded in the scientific literature. Both uncommon and rare side effects associated with sweet potatoes remain undocumented. There is limited information regarding drug interactions; however, due to their natural composition, significant interactions with medications are unlikely. It is prudent for individuals with diabetes to monitor their blood sugar levels when taking sweet potato preparations, particularly those aimed at glycaemic control, to ensure there are no adverse effects.
Dosage
Currently, the minimum effective dose of sweet potato extract for weight management is not clearly established in humans; however, animal studies suggest a 6% supplementation in the diet can be effective. For glycaemic control, human trials have utilized a dose of 4 g/day of sweet potato preparation. While there is no specified maximum safe dose of sweet potato extracts, excessive consumption is generally deemed safe. Sweet potato products can be incorporated into meals without specific timing considerations, offering flexibility for dietary inclusion. Whole sweet potatoes are suggested due to their favorable nutritional profile, though ethanolic extracts also exhibit beneficial properties, highlighting the need for more investigation into absorption factors.
FAQs
