The benefits and safety of many artificial food additives (including preservatives) are the subject of debate among Academics specializing in Food Science and Toxicology . Some methods of food preservation involve the use of Salt , Sugar or Vinegar , which are sometimes considered to be foods rather than additives. Some people believe preservatives are harmful to human health. |
