Our health depends on different factors, and nutrition is one of them. we get all nutrients, vitamins, minerals and microelements with food. however, apart from necessary, vital elements, many food products contain ingredients that are useless or even destructive for health. unfortunately, very often unhealthy food is tasty, appetizing and relatively inexpensive, so, we are tempted to buy it again and again. as a result, we receive too little healthy elements, such as protein, unsaturated fats and fiber and too many empty calories, trans fats and carbohydrates. it causes various health problems – from obesity to metabolic disease and accelerated physiological ageing.
