Summary
This product contains cashews, which are nutrient-dense and beneficial for heart health, but it is processed with peanut oil, a seed oil high in omega-6 fatty acids that can promote inflammation. The presence of sea salt is neutral, but the use of peanut oil and the processing level limit the overall healthiness of the product.

Risks
Excessive consumption can lead to high blood pressure and related health issues.

It is often refined, which may strip away beneficial nutrients and introduce harmful compounds. Compared to healthier oils like olive or avocado oil, peanut oil is less favorable due to its fatty acid profile.
