Chia Seeds
Tiny seeds with the highest plant ALA omega-3 content per gram, plus 10g of fiber in two tablespoons — useful for constipation, but easy to overdo.
Also known as: chia, Salvia hispanica seeds

Chia seeds are about 30% fat (mostly ALA, the plant form of omega-3), 30% fiber, and ~16% protein. Two tablespoons (~28g) provide ~10g fiber and ~5g ALA omega-3 — making them one of the densest fiber and plant omega-3 sources by weight.
Why they help with constipation
Most of chia's fiber is soluble. When mixed with liquid the seeds form a gel that holds water through the gut, softening stool and adding bulk. Clinical guidelines list soluble fiber (psyllium, oats, chia, flax) as a first-line approach to chronic constipation, ahead of stimulant laxatives. They take a few days of consistent intake to work — not a same-day fix.
Hydration and dose
Chia absorbs up to 12x its weight in water. Dry seeds eaten without enough fluid can swell in the esophagus or stomach and cause cramping or, rarely, obstruction. The rule is simple: soak them first (overnight oats, puddings, smoothies) and ramp up gradually. Going from zero to 2 tablespoons daily can cause bloating; starting at 1 teaspoon and increasing weekly is more comfortable.
ALA from chia is technically an omega-3, but the conversion rate to EPA/DHA (the forms that drive most of the cardiovascular and brain benefits) is low — roughly 5-10% for EPA and under 1% for DHA. Chia is a useful complement for fiber and background nutrition, but for documented EPA/DHA benefits, fatty fish or algae oil remains more efficient.
