Fats are not always bad
There are three types of fats contained in the food: saturated fat (in animal food like meat, sausage, milk, cheese, butter) essential fatty acids (e.g. in purslane, linseed oil, sunflower oil, rapeseed oil, soya oil, walnut oil) and unsaturated fat (e.g. in avocadoes, olive oil, nuts, seeds).
The consumption of essential fatty acids is very important for the human body, as they cannot be produced by the body. People who do not consume enough essential fatty acids suffer from undersupply, resulting in deficiency signs, e.g. hair loss, deficiency of blood platelets and growth disorders, occur.
Some fats, namely the saturated fats in animal food can have negative effects on our health. When too many of these foods are consumed, diseases like high blood pressure and other heart diseases, gout, gall-bladder complaint and overweight are the consequence. For this reason, you should avoid consuming animal food (except fish) and rather eat more often vegetables, fruits, fish, seeds and nuts containing a lot of unsaturated fat.
