and butylated hydroxytoluene (BHT)

preservatives (non- additive)

dehydration

heat

Why are Antioxidants are good?

they are good because they react with potentially damaging unstable molecules in our bodies making them more stable(by preventing oxidation)

how do these unstable molecules form?

Unstable molecules, or free radicals, form through various processes such as metabolic reactions, exposure to environmental pollutants, radiation, and inflammation. Their instability can lead to oxidative stress, contributing to cellular damage.

Nutraceuticals

are food or food product that may provide medical or health

ex. Glucosamine, chondroitin sulfate ae added to senior diets, joint health diets, large breed dog diets, omega -3 fatty acids
