Effects on Health

Some food additives and preservatives can have negative effects on health when consumed in large amounts.

Food additives and preservatives have been the subject of much research and debate in recent years, with many studies suggesting that they can have negative effects on health. Here are some of the specific effects that have been observed in research studies:

  1. Artificial sweeteners: Some studies have suggested that consuming artificial sweeteners such as aspartame and saccharin may increase the risk of certain cancers, including brain tumors and lymphomas. Other studies have also linked artificial sweeteners to weight gain, metabolic disorders, and an increased risk of diabetes
  2. Artificial colors: Some studies have linked the consumption of artificial colors, such as Red No. 40 and Yellow No. 5, to hyperactivity in children. Other studies have also suggested that these colors may increase the risk of certain cancers, including leukemia.
  3. Flavor enhancers:  Monosodium glutamate (MSG), a common flavor enhancer linked to health issues like headaches and allergic reactions.

  1. Sulphites: Some studies suggest that sulphites, commonly used to preserve the color of fruits and vegetables, may trigger allergic reactions in some individuals, including asthma attacks and hives.
  2. Sodium Nitrate and Nitrite: Use of sodium nitrate and nitrite as preservatives and color fixatives in processed meats such as bacon, ham, hot dogs, and deli meats. Research has shown that consuming these additives can increase the risk of developing certain types of cancer, specifically colorectal and stomach cancer.
  3. Trans Fats: Improves texture and extend shelf life in processed foods, also known as partially hydrogenated oils. Research has shown that consuming trans fats can increase the risk of heart disease. The American Heart Association (AHA) states that consuming trans fats increases the risk of heart disease by raising bad cholesterol levels and lowering good cholesterol levels.
  4. BHA and BHT: Used as preservatives in processed foods such as cereal, crackers, and baked goods. Research has suggested that these additives may increase the risk of cancer, specifically lung and liver cancer. The Journal of the National Cancer Institute published a study in 1981 that found a connection between high intake of BHA and BHT and an increased risk of lung cancer.
  5. Propylene glycol: Used a humectant, emulsifier, and preservative in processed foods such as ice cream, frosting, and soft drinks. Research has suggested that propylene glycol may cause allergic reactions and other health problems. A study published in the Journal of Allergy and Clinical Immunology in 1998 found that propylene glycol was the most common cause of contact dermatitis in food handlers.
