Walnuts are among the most nutritious nuts that can be included in a healthy diet. They are rich in healthy fats, plant-based omega-3 fatty acids, protein, fibre, antioxidants and several essential micronutrients. Including a small portion of walnuts in your daily diet may support overall health, particularly heart health. However, walnuts are not a miracle food and are best consumed as part of a balanced and varied diet.
Supports Heart Health
One of the biggest nutritional advantages of walnuts is their healthy fat content. They are particularly rich in alpha-linolenic acid (ALA), a plant-based omega-3 fatty acid. Including walnuts as part of a healthy eating pattern may help support healthy cholesterol levels and cardiovascular health. Their fibre and antioxidant content may also contribute to better heart health.
May Benefit Brain Health
Walnuts are often called a “brain food” because of their combination of healthy fats, omega-3 fatty acids, antioxidants and polyphenols. These nutrients may help protect cells from oxidative stress and support overall brain health. However, eating walnuts alone does not automatically improve memory or intelligence. They should be considered one part of an overall healthy diet that supports brain function.
Good Source of Fibre
Walnuts provide dietary fibre, which is important for maintaining a healthy digestive system. Fibre also supports beneficial gut bacteria. Adding a small portion of walnuts to your regular meals can therefore contribute to your overall daily fibre intake.
Rich in Antioxidants
Walnuts contain antioxidant compounds, including polyphenols, which help the body deal with oxidative stress. A diet rich in antioxidant-containing foods can contribute to overall health and may help protect cells from damage caused by free radicals.
Can Walnuts Help With Weight Management?
Walnuts contain a combination of healthy fats, protein and fibre, which can help you feel fuller after eating. This may make them a useful snack for people trying to manage their weight. However, walnuts are also calorie-dense. Eating large quantities can add significant calories to the diet. A small portion is therefore a better choice, especially for those trying to lose weight.
What Is the Best Way to Eat Walnuts?
Walnuts do not have to be soaked before eating. Raw or dry-roasted walnuts without added salt or sugar are good options. They can be eaten as a snack or added to oatmeal, yoghurt, fruit bowls and salads. They can also be incorporated into smoothies or used as a topping for various dishes.
Soaking walnuts overnight is a common practice, but it is not essential. Soaking can change their texture and make them easier to chew, but there is no strong evidence that soaked walnuts provide significantly greater nutritional benefits than raw walnuts. You can therefore choose whichever method you prefer.
How Many Walnuts Should You Eat in a Day?
A commonly recommended serving of nuts is around 28 grams, or a small handful, per day. If walnuts are the only nuts you are eating, a small handful is generally enough. The ideal quantity can vary depending on your overall diet, calorie needs and individual health requirements. Eating more walnuts does not necessarily mean getting more health benefits.
Can Everyone Eat Walnuts?
People with a tree-nut allergy should avoid walnuts. Anyone with a known nut allergy should not try walnuts without appropriate medical advice. It is also better to choose plain walnuts rather than varieties coated with sugar, chocolate or excessive salt.
A small handful of walnuts can be a simple addition to a healthy diet. But instead of relying on a single food for better health, include walnuts as part of a balanced diet containing vegetables, fruits, whole grains, pulses and other nutritious sources of protein and healthy fats.
