Choosing the Right Nuts: A Guide to Their Nutritional Benefits

Nuts are widely recognized as a healthy snack option due to their content of healthy fats, protein, fiber, vitamins, and minerals. Studies indicate that regular nut consumption is associated with a lower risk of cardiovascular diseases and improved cholesterol levels. However, the variety of nuts available means choosing the right type for individual needs is important, as their nutritional profiles differ significantly.

Naturopath Eden Elbahar from Maccabi-Tivi clinic emphasizes that while culinary nuts like almonds, walnuts, and cashews are grouped together, their nutritional value varies. He advises against seeking the single 'healthiest' nut, instead recommending a personalized approach and rotating different types. A general daily recommendation is about 30 grams, or a small handful, which typically ranges from 160-200 calories. This could be around 20 almonds, 14 walnut halves, 45 pistachios, or 18 cashews.

Walnuts, for instance, are a good source of alpha-linolenic acid (ALA), a plant-based omega-3, and contain beneficial polyphenols. While beneficial for heart health, plant-based omega-3 is not as efficiently absorbed as that from fish. Due to their tendency to spoil quickly, walnuts are best stored in the refrigerator in Israel and can be added to yogurt, porridge, or salads.

Almonds are rich in calcium, vitamin E, magnesium, and fiber. Consuming almonds with their skin maximizes the intake of beneficial plant compounds. Pistachios offer protein, fiber, and healthy fats, with the added benefit that shelling them slows down consumption. Pecans, often used in desserts, are also rich in unsaturated fats and beneficial compounds that may help improve blood lipid levels, though they are calorie-dense.

Cashews are a good source of iron, zinc, and magnesium, making them suitable for vegetarian and vegan diets, and their texture lends itself to pastes and sauces. Hazelnuts are another source of vitamin E and monounsaturated fats, while macadamia nuts are the most calorie-dense and lower in protein and fiber, making them more of a dietary addition than a staple snack.

Brazil nuts are exceptionally high in selenium, a mineral crucial for thyroid function and antioxidant systems. Due to the high selenium content, consuming only one to two Brazil nuts daily is recommended, and caution is advised for those taking selenium supplements. Peanuts, though botanically legumes, share similar nutritional properties with nuts and are a high-protein, cost-effective option.

For specific health goals, walnuts, almonds, and pistachios are recommended for heart health and lipid levels. Almonds and pistachios serve as satisfying snacks. Almonds are beneficial for vitamin E and magnesium intake, while Brazil nuts are recommended for selenium. Elbahar suggests a daily handful of a mix of 2-3 nut types to ensure a broad intake of nutrients.

Raw or roasted nuts are generally healthy, but fried, candied, or heavily salted varieties should be avoided. Nut butters are a good alternative if they contain only nuts without added sugar or oil. Whole nuts pose a choking hazard for children under five and should be given in crushed form or as paste. Nuts should be stored in a cool, dry place, or refrigerated for longer storage, and any bitter taste or off smell indicates spoilage.
