Nuts have earned their reputation as one of the healthiest foods on the planet. Packed with heart-healthy fats, plant protein, fiber, vitamins, minerals, and powerful antioxidants, eating just a handful each day has been linked to lower risks of heart disease, certain cancers, diabetes, and premature death. Despite being calorie-dense, research consistently shows that people who regularly eat nuts are not more likely to gain weight, and may actually have an easier time maintaining a healthy weight due to increased fullness and improved metabolism.

While every nut offers unique nutritional benefits, some stand out for specific health advantages. Here's our ranking of the healthiest nuts and why they deserve a place in your diet.

1. Walnuts

Best for:

Heart Health

Brain Health

Cancer Prevention

Walnuts are often considered the nutritional gold standard among nuts.

Unlike other nuts, walnuts are exceptionally rich in alpha-linolenic acid (ALA), a plant- based omega-3 fatty acid known to reduce inflammation and support cardiovascular health.

Key Benefits:

Richest tree nut source of omega-3 fatty acids

May lower LDL ("bad") cholesterol

Supports healthy blood vessels

Contains polyphenols that fight oxidative stress

May improve cognitive function as we age

Research suggests regular walnut consumption may reduce the risk of certain cancers through their anti-inflammatory and antioxidant effects

One ounce provides:

185 calories

4 grams protein

2 grams fiber

2.5 grams ALA omega-3s

Perfect for: oatmeal, salads, yogurt, smoothies, or eaten by the handful.

2. Almonds

Best for:

Heart Health

Weight Management

Skin

Almonds are among the most studied nuts in nutrition research.

They're exceptionally high in vitamin E, magnesium, and fiber, making them excellent for cardiovascular health and blood sugar control.

Key Benefits:

Highest vitamin E content among common nuts

Helps reduce LDL cholesterol

Supports healthy blood pressure

Promotes fullness and healthy weight

May improve gut microbiome diversity

Excellent source of calcium for bone health

One ounce contains:

Nearly 50% of your daily vitamin E needs

Perfect for: snacking, almond butter, salads, and homemade trail mix.

3. Pistachios

Best for:

Protein

Eye Health

Blood Sugar

Pistachios are one of the lowest-calorie nuts while delivering impressive nutrition. They're also rich in lutein and zeaxanthin, antioxidants that help protect the eyes.

Key Benefits:

Nearly 6 grams of protein per ounce

Pecans contain some of the highest antioxidant levels among tree nuts. They're loaded with monounsaturated fats similar to olive oil.

Key Benefits:

Supports healthy cholesterol

Rich in flavonoids and polyphenols

May reduce inflammation

Good source of manganese and zinc

Because of their buttery flavor, pecans make an excellent healthy dessert substitute.

5. Brazil Nuts

Best for:

Thyroid Function & Immune Health

Brazil nuts are nutritional powerhouse, but moderation is important. Just one to two Brazil nuts can provide your entire daily selenium requirement.

Key Benefits:

Highest food source of selenium

Supports thyroid hormone production

Essential for immune function

Powerful antioxidant protection

May help reduce inflammation

Important: Eating too many Brazil nuts regularly can lead to excessive selenium intake, so limit yourself to just one or two per day.

6. Hazelnuts

Best for:

Heart Health

Hazelnuts provide abundant monounsaturated fats and vitamin E.

Benefits:

Supports healthy cholesterol

Rich in antioxidants

Excellent source of manganese

Bone Health

Energy

Cashews are slightly lower in fiber than some other nuts but are rich in minerals.

Rich in magnesium

Supports healthy bones

Helps produce energy

Best for:

Heart-Healthy Fats

Macadamias contain the highest amount of monounsaturated fat of any commonly eaten nut.

Benefits:

Supports healthy cholesterol

Rich in healthy fats

Good source of manganese

Delicious in moderation

Because they're calorie-dense, portion control is especially important.

Honorable Mention:

Peanuts

Although technically legumes rather than tree nuts, peanuts deserve recognition.

Benefits

High in protein

Budget-friendly

Rich in niacin

Excellent source of resveratrol

Supports heart health similarly to tree nuts

Natural peanut butter with no added sugar or hydrogenated oils is an excellent pantry staple.
