Is peanut butter healthy?
In moderation. Peanut butter sits in the middle of the scale — grade C on the open 2023 Nutri-Score algorithm: fine in a balanced diet, but not a “more is better” food.
For
- Mostly unsaturated fat: saturated fat is 20% of the fat — 1.6 g per serving.
- Fiber: 6 g per 100 g, 1 g per serving.
Against
- Calorie-dense: 588 kcal per 100 g — a serving (tablespoon, 16 g) is 94 kcal.
A typical serving (tablespoon, 16 g) has 94 kcal, 4 g protein, 8 g fat and 3.1 g carbs. Other weights in the table.
How we judge this, and the sources
For oils, nuts and seeds Nutri-Score uses its own table: instead of calories it weighs the share of saturated fat in the fat, plus sugar and salt, against protein and fiber. Calories don't count against them, which is why calorie density is listed as a separate reason.
The answer comes from the food's composition, not from opinion: its Nutri-Score grade on the open 2023 algorithm, a traffic light for sugar, salt, saturated fat and fiber per 100 g, and the share of daily reference amounts in a typical serving (for salt, sugar, fiber and vegetables, those of the WHO). It rates the food's nutrient profile; it is not medical advice. Formulas, thresholds and every source are on the methodology page; last checked against the sources on November 1, 2026. The short food description was written by our language model (AI) — how we check the text.

*Where the vitamin numbers come from
Vitamins and minerals come from the USDA FoodData Central record “Peanut butter, smooth style, without salt” (FDC ID 172470, SR Legacy; public domain), checked October 14, 2026; the record was matched to this food by calories, protein and fat. % DV is per serving, against the FDA Daily Values used on Nutrition Facts labels (2,000-calorie diet). The table lists nutrients that reach at least 2% DV per 100 g; the rest are absent or trace. Varieties, seasons and brands differ, and cooking in water leaches some vitamin C and B vitamins.

Peanut Butter: swaps and alternatives
Peanut butter has a fair amount of sugar (9 g per 100 g), a lot of saturated fat (10 g per 100 g) and a fair amount of salt (1.2 g per 100 g), but our database has no same-category swap that fixes this noticeably at the same calories and is a full grade better. The simplest move is a smaller serving. How we pick swaps.
