Food Verdicts
One food, one verdict — with the numbers shown. Each week our editorial team takes a single food people actually ask about, weighs the USDA nutrition data against the clinical evidence, and gives it a plain green, yellow, or red call for constipation. No hedging, no sponsored picks.
Can peanut butter help with constipation?
A little. The label says 5 g of fiber per 100 g; the two-tablespoon spoon says 1.6 g against 190 calories. Chunky and no-salt jars do the most.
Yellow Read → 🟡Can avocado help with constipation?
The fiber qualifies — 6.7 g per 100 g beats broccoli's 2.6 g. Then a rule demotes any food reaching 10 g of fat, and avocado arrives at 14.7. Two randomized trials measured the gut changes.
Yellow Read → 🟡Does red meat cause constipation?
Not the cut — the counter. 1,561 fresh forms rate yellow and 316 processed ones rate red, on identical zero-fiber numbers. Sodium is the only label figure that tracks the split.
Yellow Read → 🟡Does pizza cause constipation?
Not the cheese — the deli meat. Every cheese-topped form rates yellow and every meat-topped form rates red, on fiber numbers that differ by under a gram.
Yellow Read → 🔴Does bread cause constipation?
The white loaf is the credible suspect — 69% perception leader, 2.7 g fiber, and a feeding trial on refined grain. Whole-wheat escapes.
Red Read → 🟡Do eggs cause constipation?
No case in the data — and no fiber either. Over 1,000 people were asked; eggs never made the binding list.
Yellow Read → 🔴Does chocolate cause constipation?
No trial says it binds — but the fiber-rich husk is discarded before the bar is made. Per piece: 1.5 g fiber, 23 g sugar.
Red Read → 🟡Do bananas cause constipation?
Not the ripe ones — 2.6 g of fiber and less bloating in trials. The folklore belongs to green bananas and the retired BRAT diet.
Yellow Read → 🟡Is cheese good for constipation?
No — zero fiber in every form we rated. But the villain reputation outruns the evidence, which is real only for a small group of children.
Yellow Read → 🔴Is granola good for constipation?
The health-snack disguise: about 1.5 g of fiber and 8 g of sugar per bar — the dose that makes oats useful never survives the wrapper.
Red Read → 🔴Does white rice cause constipation?
Not directly — but a cup carries 0.6 g of fiber, and the BRAT diet's retired staple rates red on what milling stripped away.
Red Read → 🟡Does corn cause constipation?
Not usually — 2.8 g of fiber per ear is modest, the hull that reappears later is fiber at work, and an 18-year study buried the old myth.
Yellow Read → 🟡Does yogurt cause constipation?
No for most — but with 0 g of fiber and strain-specific evidence, it is not a fix either. One small group genuinely does better dairy-free.
Yellow Read → 🟢Do prunes help with constipation?
Yes — 7.1 g of fiber plus ~14.7 g of sorbitol per 100 g, and two randomized trials behind it. The folk remedy earns its reputation.
