The Human Body is Laden with processed food that are bad. Is it true?
Disadvantages
In general, fresh food that has not been processed other than by washing and simple kitchen preparation, may be expected to contain a higher proportion of naturally occurring vitamins, fibre and minerals than the equivalent product processed by the food industry. Vitamin C for example is destroyed by heat and therefore canned fruits have a lower content of vitamin C than fresh ones.
Food processing can lower the nutritional value of foods. Processed foods tend to include food additives, such as flavourings and texture enhancing agents, which may have little or no nutritive value, or be unhealthy. Some preservatives added or created during processing such as nitrites or sulphites may cause adverse health effects.
Processed foods often have a higher ratio of calories to other essential nutrients than unprocessed foods, a phenomenon referred to as "empty calories". Most junk foods are processed, and fit this category.
High quality and hygiene standards must be maintained to ensure consumer safety and failures to maintain adequate standards can have serious health consequences.

My Diet
Based on my own diet, I agree that I eat a lot of processed food. In one meal, I eat about 50-100g of processed food.this includes fishballs, beef jerky, canned tea, jam, hot dogs, and low-fat yogurt with sugar. These are bad for health because they contain lots of preservatives.
Preservatives
Preservatives are a type of additive used to help stop food from spoiling.
Nitrates and nitrites are used to preserve meats such as ham and bacon, but are known to cause asthma, nausea, vomiting, and headaches in some people. In addition to allergic reactions, the same is true for sulfites (sulfur dioxide, metabisulfites, and others), which are commonly used to prevent fungal spoilage, as well as the browning of peeled fruits and vegetables.
Sodium nitrite in some foods is capable of being converted to nitrous acid when ingested by humans. While animal testing showed that nitrous acid caused high rates of cancer, it is still in use.
Benzoic acid aka sodium benzoate is added to margarine, fruit juices, and carbonated beverages. It can produce severe allergic reaction and even death in some people.
Sulfur dioxide is a toxin used in dried fruits and molasses as well as to prevent brown spots on peeled fresh foods such as potatoes and apples. Sulfur dioxide bleaches out rot, hiding inferior fruits and vegetables. In the process, it destroys the vitamin B contained in produce.
