What happens when there are zero antioxidants present in the body?

When there are zero antioxidants present in the body, cellular damage may occur because antioxidants play a critical role in neutralizing free radicals. Free radicals are unstable molecules that can cause oxidative stress, which leads to cellular damage, inflammation, and even cell death. This damage is linked to various chronic diseases and aging, as well as impairments in cellular function.

Antioxidants, such as vitamins C and E, and compounds like glutathione, help to protect cells from this oxidative stress by donating electrons to free radicals, thereby stabilizing them and preventing them from causing harm to cellular structures, including DNA, proteins, and lipids. Without these protective mechanisms, the accumulation of oxidative damage can disrupt normal cellular processes and potentially lead to a range of health issues.

The other options relate to cognitive functions and do not accurately describe the consequences of having no antioxidants. Cognitive abilities, memory retention, and brain function are not expected to improve or normalize in the absence of antioxidants, as oxidative stress is generally detrimental to mental function and neurological health.
