Overconsumption of calories relative to individual needs leads to physiological harm.

◐Partially SupportedNatural substances can be as harmful as synthetic ones, with examples including foxglove and hemlock, and poisons often derived from natural sources.

◐Partially SupportedMany modern fruits, vegetables, and animal breeds have been significantly altered through conventional breeding and are not unchanged over millennia.

◐Partially SupportedThe FDA's requirement to list ingredients in order of abundance does not fully clarify the dosage of individual components in ultra-processed foods.

✕Not SupportedClaims of 'chemical-free' or 'vacuum' products are meaningless, as all food and living organisms are composed of chemicals.

◐Partially SupportedThe large number of unrecognized molecules in ultra-processed foods suggests potential safety concerns.

◐Partially SupportedUnderstanding food at a chemical level is complex, and even seemingly simple foods like apples contain many chemicals that are difficult to identify or pronounce.
