However, the actual scientific and medical view of walnuts is mostly very positive.

What does eating walnuts really do?

Positive effects (confirmed by studies):
Improving cardiovascular health: Walnuts are rich in omega-3 fatty acids (alpha-linolenic acid), which help reduce levels of “bad” LDL cholesterol and blood pressure.
Support brain function: Thanks to their high antioxidant and healthy fat content, they support memory and concentration (their brain-like shape is no coincidence).

Reducing inflammation in the body: The polyphenols and vitamin E contained in nuts help fight oxidative stress.

Microbiome support: Regular consumption promotes the growth of beneficial intestinal bacteria.

What you should pay attention to (side effects/risks)
Articles with sensational headlines often mention the following factors:
Strong Allergen: Nuts are one of the most common allergens. In sensitive people, they can cause anything from a mild reaction to anaphylactic shock.
High calorie content: Nuts are very high in energy (approx. 650 kcal per 100 g). Excessive consumption can lead to weight gain.

Digestive problems when consumed in excess: Eating large amounts of nuts at once can cause bloating or diarrhea due to their high fat and fiber content.
Risk of mold (aflatoxins): Improperly stored nuts can become moldy and contain dangerous mycotoxins.
Recommended daily dose: For most healthy people, a handful of nuts per day (approx. 30 g or 7-14 halves) is ideal
