Carrageenan is a food additive used as a thickener and fat substitute in a variety of dairy and nondairy products. Concerns about potential intestinal tract damage have been raised from consuming this additive, but the speculation has not been proven. All in all, people should really be avoiding the foods that are truly unhealthy rather than worrying about each and every additive in the salty, sugary, processed foods.
Erythritol is a more recently used low-calorie, tooth-safe natural sweetener that is now industrially produced in the bulk. Even if the name sounds suspicious, has not been found to have any adverse effects. It is, furthermore, a great sugar substitute for diabetic people.
There have been many controversial studies surrounding whether aspartame, a widely used sweetener, affects the production of neurotransmitters such as serotonin and dopamine. In fact, adverse effects have been even more prominent in those with preexisting mood disorders. In one study, adverse effects on people with depression were so great that the study was canceled for the sake of humanity.
It is no secret that our favorite foods include dyes- without them, they would not be as visually appealing. However, their short "nicknames," such as "Yellow 5," mislead people, as many would be less likely to purchase the food if its actual long, chemical name were listed on the label. With studies showing that these dyes may increase attention deficits and impulsivity in children, there are more calls than ever to ban the dyes altogether, as there are no nutritional benefits to the additives, only risks.
