Every food is unique because it contains different proportions of individual nutrients. Evaluating foods in terms of their nutritional attractiveness based on an above-average content of certain nutrients is often limiting and constraining, yet it is common in Western thought (it is more advantageous to strive for a holistic view). Brazil nuts are essentially the richest source of selenium; therefore, it is advisable to monitor their intake to prevent unnecessary overdosing, as this can truly happen given the concentration of this element. Pumpkin seeds are presented as a significant source of zinc and vitamin E - these, in combination with phytonutrients, positively affect the prostate (they are associated with supportive treatment of benign prostatic hyperplasia). Sunflower seeds contain a higher proportion of vitamin E. However, they are a richer source of omega-6 fats, which, given the increased proportion of these fatty acids in the diet of the Western population, is not a particularly advantageous nutritional characteristic.
