9 Healthy Nuts That Are Low in Carbs

[suramo]

Nuts are known for being high in healthy fats and plant-based protein while being low in carbs.

Therefore, most nuts can fit into a low-carb eating plan, though certain kinds are particularly low in carbs.

For those following stricter low-carb diets like the ketogenic diet, sticking to lower-carb nuts can promote successful dieting.

Here are 9 nuts perfect for a low-carb diet:

1. Pecans

Though often associated with sweets, pecans are healthy nuts that provide a host of nutritional benefits.

They’re not only low in carbs and high in fiber but also loaded with important nutrients like thiamine (vitamin B1), magnesium, phosphorus and zinc.

Total carbs per 1-ounce (28-gram) serving: 4 grams

Net carbs per 1-ounce (28-gram) serving: 1 gram

Percent of calories from carbs: 8%

Carbs per 100 grams: 14 grams

Pecans are very low in carbs, delivering a little over 1 gram of net carbs per 1-ounce (28-gram) serving.

Often referred to as digestible carbs, net carbs refer to the number of carbs in whole food minus the fiber content.

Because your body doesn’t easily absorb naturally occurring fiber in whole foods, it’s often subtracted from a food’s total carb content to reveal the number of net or absorbable carbs.

Fiber — especially the soluble fiber found in nuts like pecans — has been shown to reduce blood sugar and improve other blood markers linked to heart disease, including “bad” LDL cholesterol.

Adding 1.5 ounces (42 grams) of pecans per day to an unhealthy diet has been found to significantly reduce heart disease risk factors in overweight adults, including triglycerides, very low-density lipoprotein (VLDL) cholesterol and blood sugar.

According to a review of 12 studies, diets that include at least 2 ounces (56 grams) of tree nuts — including pecans — per day provide significant reductions in fasting blood sugar and HbA1c.

SUMMARY

Pecans are healthy low-carb nuts that may help regulate blood sugar and reduce certain heart disease risk factors.

2. Macadamia Nuts

Macadamia nuts are low-carb, high-fat nuts that are well suited for low-carb meal plans.

They’re an excellent source of B vitamins, magnesium, iron, copper and manganese.

Total carbs per 1-ounce (28-gram) serving: 4 grams

Net carbs per 1-ounce (28-gram) serving: 2 grams

Percent of calories from carbs: 8%

Carbs per 100 grams: 14 grams

These buttery-tasting nuts are also a rich in monounsaturated fats.

Studies show that foods high in monounsaturated fats benefit heart health by reducing cholesterol levels and improving markers of inflammation in your body.

40–90 grams of macadamia nuts per day significantly reduced several blood markers of inflammation and oxidative stress (8).

Following a diet high in flavonoid-rich foods, such as macadamia nuts, may reduce your risk of heart disease, cognitive decline, diabetes and certain cancers.

SUMMARY

Macadamia nuts are an excellent source of healthy fats, antioxidants, vitamins and minerals. Including these low-carb nuts in your diet may boost heart health and reduce inflammation.

3. Brazil Nuts

Brazil nuts are large, low-carb nuts that are loaded with important nutrients.

They’re renowned for their high concentration of selenium. Just one Brazil nut delivers over 100% of the Reference Daily Intake (RDI) .

Total carbs per 1-ounce (28-gram) serving: 3 grams

Net carbs per 1-ounce (28-gram) serving: 1 gram

Percent of calories from carbs: 8%

Carbs per 100 grams: 12 grams

Selenium is a mineral involved in many critical bodily functions like metabolism, DNA production and immune response.

It’s also essential for thyroid health and acts as a potent antioxidant, protecting your cells against free radical damage.

Studies have shown that eating Brazil nuts is effective in reducing multiple markers of inflammation and improving cholesterol levels.

Because Brazil nuts are extremely high in selenium, it’s recommended that adults keep intake to under four nuts per day to avoid surpassing the upper limit of 400 mcg.

SUMMARY

Brazil nuts are low in carbs and one of the best natural sources of selenium, a mineral essential for health.

4. Walnuts

Walnuts are not only low in carbs but also loaded with nutrients, such as B vitamins, iron, magnesium, zinc, polyphenol antioxidants and fiber.

Total carbs per 1-ounce (28-gram) serving: 4 grams

Net carbs per 1-ounce (28-gram) serving: 2 grams

Percent of calories from carbs: 8%

Carbs per 100 grams: 14 grams

Eating walnuts on a regular basis has been shown to improve heart health, reduce blood pressure, promote brain function and even boost weight loss.

30 grams or about 1 ounce of walnuts per day achieved significantly greater weight loss.

Walnuts are high in healthy fats, including a plant source of omega-3 fats called alpha-linolenic acid (ALA).

Diets high in ALA-rich foods have been found to reduce the risk of heart disease and stroke.

Additionally, walnuts have been shown to improve blood sugar control in people with type 2 diabetes .

SUMMARY

Walnuts are low in carbs and provide a rich source of the plant-based omega-3 fatty acid ALA. Adding walnuts to your diet may promote weight loss, improve heart health and benefit blood sugar control.

5. Hazelnuts

Hazelnuts are rich in healthy fats, fiber, vitamin E, manganese and vitamin K.

Total carbs per 1-ounce (28-gram) serving: 5 grams

Net carbs per 1-ounce (28-gram) serving: 2 grams

Percent of calories from carbs: 10%

Carbs per 100 grams: 17 grams

They also contain numerous antioxidants which help fight inflammation in your body.

Additionally, these nuts are high in L-arginine, an amino acid that is a precursor to nitric oxide. Nitric oxide is a neurotransmitter that helps blood vessels relax and is important for heart health.

Hazelnuts are also rich in fiber and monounsaturated fats — both of which are beneficial for heart health.

Diets rich in hazelnuts help protect against heart disease by reducing inflammation, lowering blood pressure and decreasing “bad” LDL cholesterol levels.

SUMMARY

Hazelnuts are an excellent source of antioxidants and also contain heart-healthy nutrients like L-arginine, fiber and healthy fats.

6. Pine Nuts

Sourced from pine cones of evergreen trees, pine nuts have a distinct flavor and buttery texture due to their high oil content.

They’re an excellent source of nutrients and particularly high in vitamin E, manganese, magnesium, vitamin K, zinc, copper and phosphorus .

Total carbs per 1-ounce (28-gram) serving: 4 grams

Net carbs per 1-ounce (28-gram) serving: 3 grams

Percent of calories from carbs: 8%

Carbs per 100 grams: 13 grams

Like many other nuts, pine nuts have been shown to benefit heart health by lowering cholesterol levels and preventing the buildup of plaque in blood vessels .

What’s more, people who consume tree nuts — including pine nuts — on a regular basis tend to weigh less than those who don’t.

Plus, frequent tree nut consumption has been linked to lower levels of insulin resistance, reduced blood sugar, decreased inflammation and increased levels of “good” HDL cholesterol.

Try adding pine nuts to homemade trail mixes, sprinkling them on salads, toasting them or eating them raw for a healthy, simple snack.

SUMMARY

Pine nuts are packed with nutrients and adding them to your diet may benefit heart health and help you reach a healthy weight.

7. Peanuts

Though peanuts are technically legumes, they’re commonly considered nuts and enjoyed the same way.

Peanuts contain a wide array of nutrients, including folate, vitamin E, magnesium, phosphorus, zinc and copper.

They’re also an excellent source of plant-based protein, with a 1-ounce (28-gram) serving delivering an impressive 7 grams.

Peanuts are rich in antioxidants, including resveratrol, a phenolic antioxidant that has been shown to have protective effects against heart disease, certain cancers and cognitive decline.

Eating peanuts may promote weight loss and protect against heart disease.

Since they’re high in protein and have a pleasant, mild taste, peanuts make an excellent and filling ingredient that can be paired with various healthy foods.

SUMMARY

Peanuts are high in protein, vitamins, minerals and antioxidants. Eating peanuts may benefit heart health and even promote weight loss.

8. Almonds

Almonds are low-carb nuts that pack a powerful nutritional punch.

They’re an excellent source of vitamin E, magnesium, riboflavin, copper, phosphorus and manganese .

Research has shown that a diet rich in almonds promotes weight loss by significantly reducing hunger and curbing your desire to eat.

Whole almonds pair well with a variety of foods and are a convenient option for snacking on the go.

Additionally, almonds can be made into other low-carb ingredients.

For example, almond flour is a popular substitute for traditional all-purpose flour and can be used to make low-carb friendly versions of recipes like pancakes, muffins and crackers.

SUMMARY

Almonds are high-protein, low-carb nuts that can be added to your diet in a variety of ways. Almond flour is another popular way to incorporate almonds into a low-carb meal plan.
