To reap the benefits without risks, experts recommend:

A daily handful (25–30 g) of raw or roasted unsalted nuts.

Choose natural mixes, not fried or sugar-coated.

Store them in airtight containers to prevent mold and oxidation.

Conclusion

Nuts can be great allies for the brain, provided they are chosen wisely and consumed in moderation. Avoid highly processed products, those with excess salt, or those that are poorly preserved, and prioritize those rich in antioxidants and healthy fats.
