Groundnut cholesterol content is zero: peanuts are a plant food and contain no dietary cholesterol, according to USDA FoodData Central. Most of their fat is unsaturated, and controlled studies have found that diets including peanuts or peanut butter can lower LDL cholesterol compared with a typical Western diet, although peanuts are not a treatment for high cholesterol. This fact sheet explains the fat profile of peanuts, the other compounds that matter, what research says, and how raw, roasted and salted peanuts compare.
Key takeaways
- Peanuts contain 0 mg cholesterol per 100 g, like all plant foods.
- About half of the fat in peanuts is monounsaturated, and about a third is polyunsaturated.
- A pooled analysis of 25 nut trials found an average 7.4% fall in LDL cholesterol with about 67 g of nuts a day.
- Peanuts are energy-dense, so portion size and the rest of the diet still matter.
Do Peanuts Contain Cholesterol?
No. Dietary cholesterol is found only in foods from animals, such as meat, eggs and dairy. Peanuts are the seeds of a legume plant, so they contain no cholesterol. USDA FoodData Central lists 0 mg cholesterol per 100 g for raw peanuts, and the same is true for plain roasted peanuts and peanut butter made only from peanuts.
This is a common question because peanuts are high in fat. But fat and cholesterol are different things. What matters for blood cholesterol is mainly the type of fat in the diet, especially saturated and trans fat, along with overall diet, body weight, genetics and activity. Peanuts are high in fat, but most of it is unsaturated.
It also helps to separate dietary cholesterol from blood cholesterol. Blood cholesterol is carried in lipoproteins. LDL (low-density lipoprotein) is often called “bad” cholesterol because high levels are linked to fatty deposits in the arteries. HDL (high-density lipoprotein) helps carry cholesterol away to the liver. Studies on peanuts therefore look mainly at LDL, HDL, total cholesterol and triglycerides, not at the cholesterol content of the food itself.
What Is the Fat Profile of Peanuts?
The table shows the fat profile of raw peanuts per 100 g from USDA FoodData Central.
| Component (per 100 g raw peanuts) | Amount | Share of total fat |
|---|---|---|
| Total fat | 49.2 g | 100% |
| Monounsaturated fat | 24.4 g | about 50% |
| Polyunsaturated fat | 15.6 g | about 32% |
| Saturated fat | 6.3 g | about 13% |
| Cholesterol | 0 mg | — |
| Dietary fibre | 8.5 g | — |
| Protein | 25.8 g | — |

The main monounsaturated fat in peanuts is oleic acid, the same fatty acid found in olive oil. The main polyunsaturated fat is linoleic acid, an omega-6 fatty acid. The exact balance depends on the variety. High-oleic peanut varieties contain more oleic acid and less linoleic acid, which also helps them stay fresh for longer.
How Do Monounsaturated Fats, Fibre and Plant Sterols Fit In?
Researchers look at several parts of the peanut when they study blood lipids:
- Unsaturated fats: diets that replace saturated fat with unsaturated fat are associated with lower LDL cholesterol in many studies.
- Fibre: peanuts provide about 8.5 g of fibre per 100 g. Dietary fibre is part of a heart-healthy eating pattern.
- Plant sterols: peanuts contain phytosterols, mainly beta-sitosterol. Plant sterols have a structure similar to cholesterol and can reduce cholesterol absorption in the gut when eaten in sufficient amounts.
- Protein and micronutrients: peanuts also supply plant protein, magnesium, niacin, folate and vitamin E.
These parts work together within the whole diet. No single compound in peanuts explains the study results on its own.
Peanut oil is a related case. Refined peanut oil keeps most of the unsaturated fat but loses the fibre and protein of the whole kernel, and some of the minor compounds. In the 1999 study described below, both a peanut oil diet and a peanuts and peanut butter diet were tested as part of high-monounsaturated eating patterns.
What Does the Research Say About Groundnut Cholesterol Effects?
Three kinds of evidence are most relevant: controlled feeding trials, pooled analyses of trials and large observational studies.
Controlled feeding trial. In a 1999 randomised crossover study of 22 adults, a diet including peanuts and peanut butter was compared with an average American diet. The high-monounsaturated diets in the study, including the peanut diet, lowered total cholesterol by about 10% and LDL cholesterol by about 14%, without lowering HDL cholesterol.
Pooled analysis of trials. A 2010 pooled analysis combined individual data from 25 nut intervention trials with 583 adults. At an average intake of 67 g of nuts a day, LDL cholesterol fell by about 7.4% and total cholesterol by about 5.1%. The effect was dose-related, and different types of nuts had similar effects.
Observational studies. A 2017 analysis of three large US cohorts found that eating peanuts or tree nuts two or more times a week was associated with a 13–19% lower risk of cardiovascular disease. This shows an association, not cause and effect.
How Do Raw, Roasted and Salted Peanuts Compare?
Raw and dry-roasted peanuts have very similar fat profiles. Dry roasting removes water but adds no fat, so calories per 100 g rise only slightly, from about 567 kcal raw to about 587 kcal dry-roasted. Some heat-sensitive vitamins, such as thiamin and folate, fall during roasting.
- Raw peanuts: no added fat or salt, but usually cooked or roasted before eating for flavour and food safety.
- Dry-roasted, unsalted: the closest to raw in nutrition, with no added fat or sodium.
- Oil-roasted: slightly more fat and calories, and the fat profile depends on the frying oil.
- Salted: similar fat profile, but much more sodium. Choose unsalted or lightly salted where possible.
- Peanut butter: choose products made mainly from peanuts; some contain added sugar, salt or hydrogenated fats.
How much peanut is used in dietary studies? It varies. The cohort studies above used a serving of 28 g (1 oz). The pooled trial analysis had an average intake of 67 g of nuts a day. In many feeding trials, peanuts replace other fats or foods in the diet rather than being added on top, which keeps total calories steady.
This point matters in daily eating. Swapping a snack high in saturated fat or sugar for a small handful of unsalted peanuts is a different change from adding peanuts to an unchanged diet. Peanut products also vary. In the USA, a product sold as “peanut butter” must contain at least 90% peanuts, but some spreads add sugar, salt or hydrogenated fats, so read the ingredient list.
What Are the Limits of the Evidence, and Who Should Ask a Doctor?
The evidence has clear limits. Many trials are small and short. Some study mixed nuts or tree nuts rather than peanuts alone. In controlled trials, peanuts often replaced other foods, so the results reflect the whole diet change. Observational studies cannot rule out other lifestyle differences between people who eat nuts and people who do not. Results from one population may also not apply to people with different diets.
Peanuts are also energy-dense, at nearly 6 kcal per gram, so large amounts can add to weight gain if they are added to the diet without replacing other foods. Peanuts are a major allergen. People with high cholesterol, heart disease, diabetes, a peanut allergy or those on lipid-lowering medicine should follow the advice of their doctor or dietitian.

How Do You Source Peanuts from India?
For food brands that use groundnut cholesterol and nutrition messages on pack, consistent raw material matters. Specify the type, count, grade and aflatoxin limit, and keep lab reports for every lot. Java peanuts are often chosen for peanut butter and confectionery, and Bold peanuts for roasted snacks, so the end product guides the choice of kernel.
Elysium Agri Corporation exports Bold, Java and TJ peanuts from Jamnagar in Gujarat’s Saurashtra groundnut belt, in HPS and sortex grades. We also supply roasted peanuts and peanut butter. Every lot is tested for aflatoxin at an APEDA-approved lab before shipment, and we ship in 20 ft and 40 ft containers from Gujarat ports with full export documents. See our lab testing page for the full panel. Request a peanut quote →
Frequently asked questions
What fats are found in peanuts?
According to USDA FoodData Central, 100 g of raw peanuts contains about 49.2 g of fat. About 24.4 g is monounsaturated, mainly oleic acid, about 15.6 g is polyunsaturated, mainly linoleic acid, and about 6.3 g is saturated. High-oleic peanut varieties contain more oleic acid. Peanuts contain no cholesterol and no trans fat naturally.
What does research say about peanuts and LDL cholesterol?
Controlled studies suggest diets including peanuts can lower LDL cholesterol. A 1999 crossover trial found high-monounsaturated diets, including one with peanuts and peanut butter, lowered LDL by about 14% versus an average American diet. A 2010 pooled analysis of 25 nut trials found about a 7.4% LDL fall at 67 g of nuts daily.
Do peanuts contain cholesterol?
No. Dietary cholesterol is found only in animal foods such as meat, eggs and dairy. Peanuts are the seeds of a legume plant, and USDA FoodData Central lists 0 mg of cholesterol per 100 g for raw peanuts. Plain roasted peanuts and peanut butter made only from peanuts also contain no cholesterol.
How do roasted and raw peanuts compare nutritionally?
They are very similar. Dry roasting removes water but adds no fat, so calories rise slightly from about 567 kcal per 100 g raw to about 587 kcal dry-roasted, while the fat profile stays almost the same. Some heat-sensitive vitamins such as thiamin and folate fall. Oil-roasted and salted peanuts add fat or sodium.
How much peanut is used in dietary studies on heart health?
Amounts vary. Large cohort studies often use a serving of 28 g, or about one ounce, and compare people eating nuts several times a week with those who rarely do. A pooled analysis of 25 nut trials had an average intake of 67 g a day. In many trials, peanuts replaced other foods rather than being added.
