Health Benefits and Functions
Yams are a source of complex carbohydrates and fibers that contribute to various health benefits, ranging from blood sugar regulation to improved digestive processes.
Regulating Blood Sugar and Weight Management
Yams contain a type of fiber known as resistant starch, which takes longer to digest and helps in reducing appetite. Lower glycemic index values associated with yam consumption contribute to slower blood sugar rises post-meal, which is crucial for weight management and can help in preventing blood sugar spikes.

Digestive Health and Nutrient Absorption
The dietary fibers in yams not only aid in digestion by adding bulk to stool but also serve as prebiotics. Prebiotics are non-digestible compounds that foster the growth of beneficial bacteria in the gut, thereby enhancing nutrient absorption and boosting overall digestive health.
