Are hazelnuts keto-friendly?
If you’re following a ketogenic diet, you’ll want to consume a diet rich in fats, moderate in protein, and very low in carbohydrates. Eating hazelnuts is a great way to increase your dietary fat intake on a keto diet.
Hazelnuts contain monounsaturated, polyunsaturated, and saturated fats. These are important for ketone production and maintaining healthy HDL cholesterol levels.
Replacing unhealthy snacks with hazelnuts and other keto-friendly snacks may help balance blood sugar levels, combat insulin resistance, and improve insulin sensitivity.
There are so many ways to incorporate hazelnuts into your diet. Try hazelnut butter on celery, ground hazelnuts as a topping for salad or yogurt, or this delicious ketogenic Nutella recipe.

Like other tree nuts, hazelnuts contain phytic acid. Phytic acid can interfere with the absorption of copper, iron, magnesium, zinc, and calcium. You can reduce phytic acid by soaking raw hazelnuts in water overnight.
After soaking the hazelnuts, they can be dehydrated and eaten raw or roasted in the oven at a low temperature. Roasted hazelnuts are a great snack and have better nutritional value after being soaked in water.
Overconsumption of nuts can be hard on the kidneys and can lead to uncomfortable symptoms like bloating and gas. Enjoy moderate hazelnut consumption, and be careful not to overdo it!
Five health benefits of hazelnuts
1. Rich source of folate
Hazelnuts contain more folate than any other nut!
Folate—also known as vitamin B9—is an important water-soluble vitamin. It’s essential for healthy metabolism, immune function, cell growth, and blood sugar levels.
Folate is also crucial for a healthy pregnancy. Maintaining healthy vitamin B9 levels during pregnancy significantly reduces the risk of certain birth defects.
Signs of a folate deficiency include fatigue, lowered immune system function, and irritability.
Folic acid is a synthetic version of folate. It’s always better to choose dietary sources of folate rather than supplemental forms.
2. Important phytonutrients
Hazelnuts contain important phytonutrients like proanthocyanidin. This phytonutrient improves artery health by decreasing the risk of blood clots and cardiovascular diseases.
Proanthocyanidin also helps to decrease the incidence of urinary tract infections.
As an antioxidant, this potent phytonutrient is 20 times more powerful than vitamin C and 50 times more powerful than vitamin E!
3. Abundant antioxidants
Oxidation and free-radical damage can damage cell structure and mitochondria. The antioxidants present in hazelnuts protect the body from damage with their potent anticancer properties.
Hazelnuts are a rich source of vitamin E and antioxidants known as phenolic compounds. These antioxidants help protect the body from inflammation and oxidative damage that could promote cancer.
This study from the National Institute of Health highlights the effects of hazelnuts on oxidative stress. Adding hazelnuts to the diet was beneficial in improving chronic degenerative conditions without causing weight gain.
4. Trace minerals
Hazelnuts are an excellent source of the trace mineral manganese. Manganese activates enzymes involved in collagen and muscle repair.
Hazelnuts also contain copper, which is part of the vitamin C complex. Copper is an essential trace mineral for the production of collagen. It makes collagen throughout the body and also supports the adrenal glands.
Hazelnuts contain other important trace minerals, including potassium, phosphorus, calcium, magnesium, boron, and selenium.
5. Heart health
Hazelnuts can be cold-pressed into an oil. Hazelnut oil can help improve cardiovascular health by regulating blood pressure and promoting healthy blood cholesterol levels. It can also help to decrease blood cholesterol.
Hazelnuts contain the compound oleic acid, which also plays an important role in heart health. Oleic acid is a monounsaturated fatty acid known to help reduce the risk of cardiovascular disease.
Adding hazelnuts to your diet provides numerous health benefits, supports ketosis, and helps keep you full while intermittent fasting.
Hazelnuts are packed full of the most abundant antioxidants, phytonutrients, and essential vitamins and minerals.
As long as you enjoy hazelnuts in moderation, they’re an excellent and versatile food to add to your diet.
