Final answer:
Excessive consumption of sugar alcohols can cause gastrointestinal discomfort, including gas, bloating, and diarrhea, due to their incomplete absorption and fermentation in the large intestine. They can also contribute to energy imbalance and weight gain if not consumed in moderation.
Step-by-step explanation:
When sugar alcohols are consumed in large amounts, they may lead to some side effects due to their incomplete absorption in the small intestine. The common side effect of excessive consumption of sugar alcohols is gastrointestinal discomfort, including gas, bloating, and diarrhea. This is because sugar alcohols can ferment in the large intestine, attracting water and causing a laxative effect.
Additionally, sugar alcohols can contribute to an energy imbalance leading to weight gain when consumed in high quantities without proper energy expenditure. While sugar alcohols generally have fewer calories than regular sugar, they are not calorie-free, and excessive intake without moderation could negate their lower calorie benefit.
To avoid potential side effects, it's important to consume sugar alcohols in moderation as part of a balanced diet. Individuals with sensitivities may need to limit or avoid sugar alcohols to prevent discomfort.
