Think you know everything about this superfood? Think again.
1. Even though there are 21 species of walnut trees, the nuts you’ll find in your supermarket are most likely Persian or English walnuts (Juglans regia). Confusing matters further, the Central Asian country of Kyrgyzstan has the largest walnut-tree forests in the world.
2. 28 grams of walnuts, or about 14 halves, has 185 calories, 4g of protein and carbs, 2g of fibre and 18g of fat. Of those 18 fat grams, 2g are saturated, 3g are monounsaturated and the rest are polyunsaturated.
3. Walnuts are the only nut that contains large amounts of omega-3 fatty acids. That means they’re good for not only cardiovascular health but also building muscle and losing fat.
4. Lightly toasted walnuts make an excellent addition to a number of dishes. Toss them in salads, add them to green beans sautéed in olive oil or sprinkle them on Greek yoghurt. Alternatively, invest in some walnut oil. It’s expensive and not ideal for cooking (high temperatures degrade its flavour and nutrient profile), but it makes a great base for salad dressings.
5. Walnuts’ fat content makes them prone to rotting. Store shelled nuts in the freezer or fridge to improve their longevity.
