Why Are Nuts an Athlete's Superfood?
Nuts are one of the most nutrient-dense food sources in nature. They offer a balanced combination of protein, healthy fats, fiber, vitamins and minerals. For athletes, nuts are especially valuable due to their high calorie content (ideal when a lot of energy is needed), magnesium content (for muscle function) and anti-inflammatory omega-3 fatty acids. 30 g of nuts (a handful) provides ~160-200 kcal — an excellent snack before training or between meals.

🥇 Almonds — The Vitamin E Champion
Almonds are the most versatile athlete's nut. 30 g provides 37% of the daily vitamin E requirement — this antioxidant protects cell membranes from oxidative damage caused by intense training. Almonds are also high in magnesium (76 mg), which is essential for muscle relaxation and cramp prevention.
🏃 Before Training
10-15 almonds 1-2 hours before provide steady energy without a sugar spike. Combine with a banana for a complete snack.
🔄 After Training
Almonds + Greek yogurt — a combination of protein and healthy fats for muscle recovery. Magnesium helps relax muscles.
🧠 Mental Focus
Riboflavin (B2) and L-carnitine in almonds improve brain energy metabolism — beneficial before competitions that require concentration.
🧠 Walnuts — The Omega-3 Treasure Trove
Walnuts are unique — they are the only nuts that contain a significant amount of plant-based omega-3 (alpha-linolenic acid, ALA). 30 g provides 2.5 g ALA, which in the body (to a limited extent) converts to EPA and DHA.
- Anti-inflammatory effect: ALA reduces systemic inflammation after intense training. Walnut consumption is thought to reduce CRP (an inflammation marker).
- Brain health: Polyphenols and omega-3 improve cognitive function — this is important for athletes whose sports require quick decisions.
- Source of melatonin: Walnuts naturally contain melatonin — a handful of nuts in the evening can improve sleep quality.
- Best Time: In the evening — due to melatonin and the anti-inflammatory effect of omega-3 during nighttime recovery.
💪 Cashews — A Source of Magnesium and Copper
Cashews stand out for having the highest copper and magnesium content among popular nuts. Copper is essential for collagen synthesis (for joints and tendons), and magnesium for muscle function.
- Copper for joints: Copper is a cofactor for lysyl oxidase — an enzyme responsible for the cross-linking of collagen and elastin. Especially valuable for athletes with joint problems.
- Magnesium for muscles: 83 mg of magnesium per 30 g — that is 20% RDA. Helps prevent cramps and improves muscle relaxation.
- Iron: 1.9 mg of iron per 30 g — beneficial for endurance athletes prone to iron deficiency.
- How to Use: Suitable before training (easier to digest than almonds) or as a snack between meals.

❓ Frequently Asked Questions About Nuts
When Is the Best Time to Eat Nuts — Before or After Training?
Due to their high fat content, nuts are digested slowly, so before training eat them at least 1.5-2 hours beforehand or choose a smaller portion (10-15 g). After training, nuts are suitable together with fast carbohydrates and protein (e.g., yogurt + nuts + banana).
Are Roasted Nuts Healthier?
Raw (unprocessed) nuts retain all nutrients. Roasting (especially at high temperature) can destroy some vitamin E, B-group vitamins and omega-3 fatty acids. If you choose roasted, buy dry-roasted, without oil and salt.
How Many Nuts per Day Are Too Many?
More than 60-80 g per day can cause digestive discomfort due to the high fat and fiber content. It is also already 400-500 kcal from nuts alone. Follow the recommendation of 30 g (one handful). Do not eat more than 2-3 Brazil nuts per day due to their extremely high selenium content.
Are nuts good for weight loss?
Yes, despite the high calorie content! Regular nut consumption (30 g/day) is thought not to be associated with weight gain — rather the opposite. Fiber and protein provide a feeling of satiety, and some of the calories from nuts are not fully absorbed (especially in almonds — ~20% less).
