Several food ingredients can cause or lead to depression, but the main problem is refined sugar and processed fructose, which feed pathogens in your gut, allowing them to overtake more helpful bacteria (Mercola, 2015).
Diets high in sugar also sets off a flood of chemical reactions in your body that build up chronic inflammation, which over the long term disturbs the usual functioning of your immune system and destroys your brain (Mercola, 2015).
Diets containing high amounts of processed foods are also linked to increased rates of anxiety, one theory is that exposure to those added sugars can wreak havoc in your gut, where the majority of serotonin production occurs (Brown, 2018). Serotonin is a natural occurring neurotransmitter in our body, and when the chemical additives, commonly used in processed foods, are consumed it can have a negative affect towards your body’s ability to maintain healthy levels (Salters, 2017).
Another reason is that all the added sugars cause blood glucose a lot faster and increased insulin production, which sets in a motion a roller coaster metabolic process that can result in hyperactivity followed by lethargy. Also, because the added sugars can become highly addictive, your body continuously wants more, repeating this process over and over (Brown, 2018).
Research displays that there are certain chemicals that have been added and naturally occur in red and processed meat that cause the food to be carcinogenic which is known to cause cancer. Processed meats include bacon, ham, Devon, frankfurts, chorizo, cabanossi and kransky (Cancer council, N.D).
To decrease the risk of cancer, the cancer council confirms that we should be eating no more than one serve of lean red meat per day or two serves 3-4 times in a week (Cancer council, N.D). e.g. one serve = 1 lamb chop (100g) and two serves = 1 medium scotch/porterhouse fillet (200g). The cancer council say that if you eliminate all red and processed meats or keep them to an absolute minimum then you will decrease the chance of cancer.
Research by the Harvard School of Public Health suggests that diets high in processed meat and sugar sweetened foods are more prone to obesity rates increasing than diets of whole grains, fruits and vegetables (Nina K, 2017). Obesity leads risk to many body problems such as heart attacks, stroke, arthritis, type 2 diabetes and certain cancers (Nina K, 2017).
In conclusion processed meat contains harmful chemical compounds that may increase the risk of chronic disease. The most widely studied compounds include Nitrite, N-Nitroso Compounds and Nitrosamines, Polycyclic Aromatic Hydrocarbons, Heterocyclic Amines and Sodium Chloride (Arnarson, 2017).
Meat production is highly inefficient – this is particularly true when it comes to red meat. To
produce one kilogram of beef requires 25 kilograms of grain – to feed the animal – and
roughly 15,000 litres of water. Pork is a little less intensive and chicken less still.
Animal farms may produce food, but they also produce massive amounts of animal waste
like urine and manure that emit around 400 different harmful gases into the atmosphere.
Because thousands of animals are kept together in factory farms, the concentration of the
gases produced can be extremely dangerous to the local community. Approximately 80
percent of ammonia emissions in the U.S. comes from animal waste.
