Prunes are more effective than psyllium for constipation relief. A systematic review (Lever et al., Aliment Pharmacol Ther 2014) and an RCT (Attaluri et al., Aliment Pharmacol Ther 2011) both confirmed prunes at 100 g/day increased stool frequency in adults. Sorbitol (~15 g per 100 g) is the primary mechanism. A 2024 dose-response meta-analysis (Heydarian et al.) extended benefits to blood pressure.
How should I track Prunes?
Prunes is high in fiber. Dried fruits like Prunes are one of the sneakiest calorie sources because they look small but pack serious energy. Removing the water concentrates the calories — a small handful of dried fruit can match a full bowl of fresh fruit calorically. Research (Almiron-Roig et al., Appetite 2013) shows that people underestimate calorie-dense foods by 50–200% when portioning by eye. Weigh on a scale and pre-portion if snacking. Also check whether your variety is sweetened or unsweetened — the sweetened versions add 10–15% more calories from the sugar coating.
