What is the primary concern related to oligosaccharides in black-eyed peas that requires specific preparation?

They can lead to gas and bloating if not properly digested

Black-eyed peas, similar to other legumes, naturally contain certain complex carbohydrates called oligosaccharides. When these compounds reach the lower digestive tract undigested, they become a food source for gut bacteria, leading to fermentation. This fermentation process results in the production of gas, which manifests externally as uncomfortable bloating and general digestive upset for sensitive individuals. To minimize this issue, specific preparatory steps are highly recommended. The text advises that soaking the dried peas prior to cooking is an effective first measure, as this process leaches out a significant portion of these gas-producing carbohydrates. Following the soak, thoroughly rinsing away the soaking water further aids in mitigating potential digestive discomfort.
