Are peanuts good for women? They can be a great food choice for meals and snacking.

These humble little legumes deliver protein, healthy fats, fiber and a surprisingly useful collection of vitamins and minerals. They can fit remarkably well into an overall eating plan that supports cardiovascular health and weight management. They also provide nutrients relevant to reproductive health.

For a food that usually gets relegated to a snack bowl or a jar of peanut butter, peanuts have a lot more going for them. Here’s what women should know about their benefits, their connection to sexual health and a few reasons you might want to think twice before making them a daily habit.

Why are peanuts good for women?

Peanuts earn their place among foods worth eating regularly because they pack a lot of nutrition into a small serving. They provide protein, unsaturated fats, fiber and important nutrients including vitamin E, niacin, folate, magnesium and zinc.

Several of these nutrients are particularly relevant to women’s health. Folate is important for reproductive health, magnesium supports normal muscle and nerve function and vitamin E helps protect cells from oxidative stress. Peanuts also provide arginine, an amino acid the body uses to make nitric oxide, which helps regulate blood flow.

Nutrition

A one-ounce serving of salted, dry-roasted peanuts contains 164 calories and approximately:

6.6g protein (13% DV)
2.2mg vitamin E (11% DV)
3.8mg niacin (19% DV)
40.6mcg folate (10% DV)
49.3mg magnesium (12% DV)
.9mg zinc (6% DV)

What do peanuts do to a woman’s body?

Peanuts provide a combination of protein, unsaturated fats, fiber and important vitamins and minerals that can support several aspects of women’s health. Their potential benefits include cardiovascular health, circulation, sexual function, fertility and weight management.

Heart health and circulation

A healthy cardiovascular system is relevant to sexual function as well as overall health. Peanuts can be part of a dietary pattern that supports cardiovascular health, particularly when they replace snacks high in refined carbohydrates or saturated fat. Peanuts contribute to cardiovascular health in several ways.

Peanuts contain mostly unsaturated fats. Replacing foods high in saturated fat with foods rich in unsaturated fats can help lower LDL cholesterol and support heart health.

Peanuts contain arginine, an amino acid involved in the body’s production of nitric oxide. Nitric oxide plays a role in normal blood-vessel function. However, there is not strong evidence that eating peanuts specifically improves circulation or sexual function.

Peanuts also provide fiber. A one-ounce serving contains about 2.4 grams, and higher fiber intake is associated with reduced inflammation. Chronic inflammation has been linked to impaired circulation and sexual dysfunction, which can negatively affect arousal and sexual function. While there are no studies specifically linking the fiber in peanuts with improved circulation, the choice of increasing fiber with sources like peanuts shows strong benefits.

For women, healthy circulation matters to sexual response because increased blood flow to the clitoris and vaginal tissues is part of normal arousal. Cardiovascular health and sexual function are closely connected, and poor cardiovascular health has been linked to sexual dysfunction, including reduced arousal and vaginal dryness. This is not to say that peanuts specifically are a cure for female sexual dysfunction but that they contain nutrients which are relevant to female sexual well-being.

Additionally, a 2017 Harvard study found that eating a few servings of peanuts per week may improve heart health.

Sexual health

Peanuts are not a magic libido food, but their combination of arginine, healthy fats, fiber and other nutrients supports systems that are relevant to sexual health.

Because blood flow is important to female arousal and sexual function, foods that support cardiovascular health and healthy circulation can be part of a diet that supports sexual function.

Fertility

Peanuts provide folate, a B vitamin that is important for women’s reproductive health. Adequate folate intake before and during pregnancy helps prevent neural tube defects in developing fetuses and supports fetal health.

Folate may also have a connection to sexual function. One study of postmenopausal women found that increased folate intake significantly improved sexual function without adverse effects. Keep in mind that this study used supplementation rather than relying on food sources.

Heart health is also connected to fertility. Chronic conditions including obesity, diabetes and dyslipidemia can affect both cardiovascular and reproductive health.

Weight management

Peanuts combine protein, fiber and healthy fats, which can promote satiety and help reduce hunger between meals. Their relatively slow digestion can also help keep you feeling full longer.

A 2009 observational study found that women who regularly ate peanuts had a lower risk of long-term weight gain and obesity.

Maintaining a healthy weight can also support sexual health, since excess weight is associated with hormonal changes and sexual dysfunction.

Are boiled peanuts good for women?

Yes. Boiled peanuts can provide many of the same nutritional benefits as other forms of peanuts, including protein, fiber, healthy fats and important vitamins and minerals.

The main difference is preparation. Boiling changes the texture and can affect the amount of some nutrients, but boiled peanuts can still be a nutritious addition to a woman’s diet.

If you buy prepared boiled peanuts, pay attention to the sodium content, particularly if you eat them regularly.

Are peanuts and groundnuts the same thing?

In many contexts, yes, they’re the same. Peanuts are a type of groundnut, and the terms are commonly used interchangeably in many parts of the world.

The terminology can get confusing because “groundnut” may refer to other leguminous crops in some regions. If you see claims about the benefits of groundnuts, check the source to make sure it is referring to peanuts.

Are there side effects of peanuts for women?

Peanuts are generally safe for most women, but there are a few risks to consider.

Peanut allergy is the most serious risk. Peanuts are a common food allergen, and reactions can range from mild symptoms to severe, life-threatening anaphylaxis. Approximately 1.8% of adults have a peanut allergy.

Salted or flavored peanuts can also add significant amounts of sodium. If you eat peanuts regularly, choosing unsalted varieties can help keep your overall sodium intake in check.

In rare cases, peanuts grown or stored in humid conditions may be exposed to aflatoxin, a toxin produced by certain fungi. Food safety standards in the United States keep this risk low.

For most people, choosing unsalted peanuts and eating moderate portions makes them a safe, nutrient-rich food.

How to incorporate peanuts into your diet

Peanuts and peanut butter are versatile and easy to add to meals and snacks. Whether raw, boiled, blanched or dry roasted, they provide protein, fiber, healthy fats and important vitamins and minerals. Keep an eye on sodium content if you’re monitoring your salt intake.

Peanuts make a satisfying, energy-boosting snack. You can also use peanut flour for baking or add peanut butter to oatmeal, smoothies or sauces. Our nutrition director, Delahna Flagg, recommends consuming 1 to 1.5 ounces of peanuts per day for optimal benefits.

Storage tips

Peanuts can go rancid over time. The National Peanut Board recommends storing them in an airtight container in a cool, dry space. Once opened, they will start to lose freshness after about four weeks. Bagged, they can be stored in the refrigerator for 4-6 months.
