Although it is already 20 years old in the USA, the "clean eating" concept has been gaining attention, especially in recent years. Great importance is attached to unprocessed products without additives and flavor enhancers - in other words, a short list of ingredients.

These trends make it possible to have access to fresh, natural and healthy food almost everywhere, including nutritious snacks. Because these are also very much on trend. Vegetable potato chips or homemade energy balls made from dates and many other such snacks are increasingly finding their way into the pockets of health-conscious people.
