Processed edible-like substances that are considered convenient foods or pre-prepared foods are those that have gone through substantial modification, transforming them from their original natural form. The modification process strips them of their nutrients, bleaches them, and combines different chemicals or additives in them such as artificial colourings, flavourings, preservatives, thickening, softening, gelling, foaming and stabilizing agents, trans fats, too much salt, and sugars that change or improve the look, taste, shape, and feel of foods, but many of these things have been proven to have harmful health effects ranging from headaches to cancers.
Some examples of processed items are carbonated soft drinks, energy drinks, sugary coffee drinks, packaged chips and cookies, sweetened breakfast cereals, baking mixes, hot dogs, fish sticks, frozen meals, instant soups, candies, confectioneries, packaged bread and buns, protein and energy bars, boxed pasta products, ice cream, cocoa mixes, margarine, and spread.
Processed items are just edible things but are lacking in nutritional components that are required in a food item to help in carrying on vital body functions apart from fuelling the body. The nutritionally deficient and high empty calorie content of these items don’t serve the purpose of eating and don’t confer any therapeutic effects to fight against disease or illness and for achieving optimal health and wellness.
The nutrient removal during the processing also changes the digestion pathway in your body which usually results in over-consuming calories and giving you weight gain. For example, during the removal of bran and germ in white flour, fiber is also removed and without fiber, your digestion is affected, you don't feel full for long resulting in feeling hungrier faster, and also triggering higher fat storage.
These items are also designed that they pinpoint reward centers in your brain that encourages you to keep eating and the problem is further aggravated when this increased intake comes at the cost of your intake of quality wholesome foods. Eating processed items gives you excessive calories, unhealthy fats, high sodium and sugar content with low fiber and other essential nutrients resulting in negatively impacting our bodies and playing a role in the development of diabetes, hypertension, obesity, hyperlipidemia, heart disease and certain types of cancer.
