Is Peanut Butter Bad for Gout? Purines, Sugar and Portions
Peanut butter is low in purines, about 16 mg per 2 tablespoons, and plant protein isn't linked to gout. Choose peanuts-and-salt jars and watch portions.
TL;DR
- Peanut butter is low in purines: about 16 mg in a 2-tablespoon serving, and plant protein hasn’t been linked to higher gout risk.
- Sweetened jars add only about 2 g of sugar per serving, so the label matters less than the honey, chocolate and jelly that often come with it.
- The practical limit is calories, not purines: about 190 per serving. Measure it.
Peanut butter isn’t bad for gout. It’s low in purines, the purines it has come from a plant, and large studies of plant protein haven’t found a link to higher gout risk.
What deserves attention is what’s in the jar besides peanuts, what you spread it on, and how big the spoonful is. At about 190 calories per 2 tablespoons, peanut butter is easy to overeat, and extra weight is a real gout risk factor.
How many purines are in peanut butter?
In the US, anything sold as “peanut butter” has to be at least 90% peanuts; added seasonings and stabilizers, such as salt, sugar and hydrogenated oils, can make up no more than 10% of the weight. So its purine content tracks peanuts closely.
Our purine chart lists peanuts at about 50 mg per 100 g, right at the border of the Low and Moderate bands (see our peanuts guide). That figure comes from a Japanese laboratory analysis (Kaneko and colleagues, 2014), which measured 49.1 mg per 100 g and is the only peanut entry in the USDA and ODS-NIH purine database. Neither source lists peanut butter separately, so these per-serving figures are based on peanuts:
| Food | Serving | Purines per serving | Protein |
|---|---|---|---|
| Peanut butter | 2 tbsp (32 g) | ~16 mg | 7 g |
| Almond butter | 2 tbsp (32 g) | ~10 mg | 7 g |
| Eggs | 2 large (100 g) | under 3 mg | 13 g |
| Plain nonfat Greek yogurt | 170 g | ~14 mg | 17 g |
| Firm tofu | 100 g | ~25 mg | 17 g |
| Deli ham | 2 oz (56 g) | ~90 mg | 9 g |
| Chicken breast, roasted | 3 oz (85 g) | ~155 mg | 26 g |
Purines from our purine chart (peanuts 50, almonds 30, eggs under 2.5, Greek yogurt 8, tofu 25, deli ham 160, cooked chicken breast 185 mg/100 g). Deli ham varies a lot (published analyses range from about 70 to 250 mg/100 g), and so does cooked chicken breast (about 180 to 370). Protein from USDA FoodData Central.
Gram for gram, peanut butter gives you fewer purines than meat. Per gram of protein the gap is smaller, because peanut butter is mostly fat. Its advantage is the kind of purine, and the fact that a normal serving is small.
Does plant protein raise gout risk?
The evidence says no. In the Health Professionals Follow-Up Study, which tracked more than 47,000 men for 12 years, eating more meat and seafood was linked to more gout, while purine-rich vegetables and total protein were not. Men with the highest vegetable-protein intake actually had a 27% lower risk than those with the lowest, although the overall trend wasn’t statistically firm.
Longer follow-up in the same cohort found that men whose diets looked most like the DASH pattern, which includes nuts and legumes, had a 32% lower risk of gout. The Arthritis Foundation’s gout cheat sheet lists nuts and legumes among the foods to eat.
How much sugar is in peanut butter?
Less than most people assume. Here’s USDA FoodData Central data for 2 tablespoons:
| Type | Sugar | Fructose (approx.) | Calories |
|---|---|---|---|
| Natural (peanuts + salt) | ~1.5 g | under 1 g | ~190 |
| Regular smooth, sweetened | ~3.4 g | ~1.7 g | ~190 |
| Reduced-fat | ~3.3 g | under 2 g | ~190 |
| 12 oz regular cola, for comparison | ~37 g | ~22 g | ~155 |
Natural figure based on USDA dry-roasted peanuts. Peanut butter fructose estimated as half of its sucrose. Reduced-fat serving is 2 tbsp (36 g).
The added sugar in a typical sweetened jar is about 2 g per serving (brands vary, so check the “added sugars” line), so switching to natural is a good habit rather than a big uric-acid lever. The bigger sugar sources are around the peanut butter:
- Honey, chocolate and flavored peanut spreads, which can be closer to dessert. Honey is about 40% fructose (is honey bad for gout).
- Jelly and jam on white bread, especially with a sugary drink. See does sugar cause gout for why fructose is the sugar that matters.
- “Peanut butter spread” labels. Products that don’t meet the 90% peanuts standard can’t be called peanut butter, and they often contain more sweeteners or fillers.
Reduced-fat peanut butter isn’t a gout upgrade. USDA data show about 36 g of carbohydrate per 100 g versus 22 g for regular, because some of the fat is replaced with carbohydrate, and the calories per serving come out about the same.
Does the salt or oil in peanut butter matter?
A little, but not for uric acid. Salted peanut butter has about 136 mg of sodium per 2 tablespoons, while unsalted versions have about 5 mg. Salt doesn’t raise uric acid, but gout often comes with high blood pressure, so unsalted or lightly salted jars are a sensible default if you eat peanut butter daily.
The oil is mostly unsaturated fat from the peanuts themselves. Some brands add a small amount of hydrogenated vegetable oil to keep the peanut oil from separating, which US rules allow within that 10% limit. Jars with only peanuts and salt skip it, so the oil rises to the top. That’s normal: stir it back in, and store the jar upside down or in the fridge to slow separation.
Is peanut butter OK during a gout flare?
Yes. During a flare, many people try to keep purines low while still eating enough protein, and peanut butter is one of the easier ways to do that. A couple of tablespoons on oatmeal or whole grain toast, alongside eggs, milk or plain yogurt, makes a low-purine meal. Focus the rest of the day on water, vegetables and fruit, and skip alcohol and sugary drinks until the flare settles.
How much peanut butter is reasonable with gout?
Purines aren’t what limits peanut butter; calories are. Two tablespoons carry about 190 calories and 16 g of fat. That’s fine as part of a meal, but it’s easy to eat three or four servings straight from the jar. For people carrying extra weight, the American College of Rheumatology’s gout guideline recommends a weight-loss program.
A reasonable pattern for most people:
- One or two 2-tablespoon servings a day, measured with a real tablespoon at first.
- Spread it on something useful: whole grain toast, oatmeal, apple or banana slices, or celery.
- Blend it into a smoothie with milk or plain yogurt, which adds dairy protein, rather than fruit juice.
- Treat it as a supporting protein. Eggs, plain Greek yogurt, milk and cheese deliver more protein with even fewer purines.
If you’re tracking snacks, an app like Urica can log peanut butter and whatever it’s spread on, which is usually where the sugar is.
What are better choices than regular peanut butter?
| Instead of | Try | Why |
|---|---|---|
| Sweetened or “spread” jars | Peanuts and salt, nothing else | Only the peanuts’ own sugar |
| Honey or chocolate peanut spread | Natural peanut butter with cinnamon | Skips most of the added sugar |
| PB&J on white bread | Peanut butter and banana on whole grain toast | Fiber and fruit instead of jelly |
| Peanut butter from the jar | A measured 2 tbsp with apple slices | Keeps calories in check |
| Peanut butter as your only snack protein | Alternate with almond butter, eggs, Greek yogurt | Almonds are lower in purines (almonds and gout) |
The Bottom Line
Peanut butter is a gout-friendly food. It’s low in purines, the purines are plant-based, and plant protein hasn’t been linked to higher gout risk. The sugar difference between sweetened and natural jars is small; the bigger wins are skipping honey and chocolate spreads, not pairing it with jelly and white bread, and keeping portions to a measured couple of tablespoons so the calories don’t creep up.

Frequently Asked Questions
How many purines are in peanut butter?
Peanut butter is made almost entirely of peanuts, which measure about 50 mg of purines per 100 g. A standard 2-tablespoon serving (32 g) therefore carries roughly 16 mg. That is a small fraction of the roughly 155 mg in a 3-ounce roasted chicken breast, and it's plant purine, which large studies have not linked to higher gout risk.
Is natural peanut butter better for gout?
Yes, modestly. A jar with just peanuts and salt has about 1.5 g of sugar per 2 tablespoons, all from the peanuts. Regular sweetened peanut butter has about 3.4 g, so the added sugar is small, about 2 g per serving. The bigger reason to choose natural is to avoid habits like honey or chocolate peanut spreads, which carry much more sugar and fructose.
How much peanut butter can I eat with gout?
For most people, one or two 2-tablespoon servings a day fits comfortably. Purines aren't the limit here; calories are. Each serving has about 190 calories, and extra body weight is linked to higher uric acid. Measure with a spoon rather than eating from the jar, and spread it on whole grain toast, oatmeal, apple slices or celery rather than white bread with jelly.
Is peanut butter a good protein source for gout?
It's a helpful supporting protein, not a main one. Two tablespoons give about 7 g of protein with low, plant-based purines, but also about 16 g of fat and 190 calories. For bigger protein doses with very few purines, eggs, plain Greek yogurt, milk and cheese are better options. Use peanut butter to round out a meal or snack.
