Nuts are often highlighted as an important part of the Mediterranean diet, and experts point to several varieties with specific health benefits.
According to dietitians, some nuts may be especially beneficial for the brain, heart and gut microbiome health, OW reports.
Brazil nuts

Brazil nuts are known as one of the largest natural sources of selenium. The mineral plays an important role in the immune system and thyroid function.
Selenium in focus

According to dietitian Amanda Holtzer, selenium may also affect cholesterol, inflammation and blood sugar levels. Just two Brazil nuts can meet the daily selenium requirement for adults.
Risk of excessive intake

OW also notes that consuming too much selenium may lead to selenium poisoning, including digestive problems.
Macadamia nuts

Macadamia nuts have a buttery flavor and a high content of monounsaturated fats, which are associated with heart health.
Moderate intake

Dietitian Fiorella DiCarlo explains to OW that moderate daily consumption, according to studies, does not appear to negatively affect weight or cholesterol levels.
Use in meals

Macadamia nuts are often used in desserts, but they can also be combined with salads and fruit.
Pecans

Pecans contain high amounts of antioxidants such as polyphenols and tocopherols, as well as monounsaturated fats.
Fiber and digestion

Amanda Holtzer points out that pecans may help lower LDL cholesterol. They also contain fiber, which supports digestion and supports satiety.
Cashews

Cashews are popular in plant-based diets and are known for their creamy texture.
Healthy gut flora

According to dietitian Carlyne Remedios, the fiber in cashews may increase the production of butyrate, which is linked to colon health and a healthy gut microbiome.
Peanuts

Although peanuts technically belong to the legume family, their nutritional profile resembles that of other nuts. They are rich in plant protein, vitamin E and antioxidants.
Pistachios

Pistachios contain fewer calories and more protein than several other nuts. They also contain lutein and zeaxanthin, which are associated with eye health.
Almonds

Almonds are highlighted as one of the most balanced nuts. They contain large amounts of vitamin E and fiber, which may help with satiety and maintaining healthy cholesterol levels.
Walnuts

Walnuts are described as particularly beneficial for the brain. They are rich in omega-3 fatty acids and polyphenols, which may help protect blood vessels and support cognitive function.
