Expert Solution

Food processing affects the fats in the food in the following ways:

  • Depending upon the method of cooking, the amount of fat in the food may be increased or decreased.For example, grilling will reduce the fat content and frying will increase it.
  • Processed foods are rich in unhealthy fats like cheap fats, vegetable oils(soyabean oil) which are often hydrogenated and are converted into trans fat
  • These fats contain omega-6 fatty acids which lead to oxidation and inflammation in the body, ultimately increasing the risk of heart disease

Trans-fats are considered the most detrimental to our health because they increase low density lipoproteins i.e. LDL (bad cholesterol) levels and decrease the levels of high density lipoproteins i.e.HDL(good cholesterol) which increases the risk of heart disease,stroke and type 2 diabetes.

Trans fat are present in food items like doughnuts,cakes,cookies,frozen pizza,etc.Trans fat consumption should not be more than 2 grams per day.
