The dietary antioxidant fad is mostly BS. They're supposedly meant to counteract oxidative stress and specifically free radicals. Both of those things are part of a healthy life and you would die without them. So any real impact is not so simple as "just counteract those bad things". Dietary antioxidants don't always lead to higher intracellular antioxidant levels, either.

Some dietary antioxidants so lead to higher intracellular levels and may help buffer oxidative stress (like from exercise) but there isn't much evidence that it doesn't just boil down to "eating your vegetables is good for you".

Sleeping more (and in tact with your circadial rhytm) and drinking more water keeps the radicals at a lower level tho, keeping you healthier in age. That or fasting like a fakir your whole life, keeping your cells in an "safe energy and clean up" mode.

Edit: radicals, not oxidants

You need oxidants to live. Issues stemming from oxidants are about levels of free radicals getting too high in the wrong places for too long.

Getting good sleep, eating a balanced diet, reducing stress, and getting enough exercise are the best ways to reduce the chances of such a scenario. Realistically, these things are also just a way to maximize wellness and health overall and it is probably not very useful for most people to think of this in terms of oxidation.

It’s not that free radicals are good (they are necessary, but excess free radicals are definitely bad), but more so that there is no solid research to suggest that dietary antioxidants have any effect whatsoever. All the studies that show any beneficial effect have been shown to have major flaws or have not been able to be reproduced consistently.

Oxidative Stress is not part of a healthy life. It's literally stress on your cells ability to respirate and detoxify. It causes DNA fragmentation in low amounts and apoptosis/cell death among other serious biological complications like cancer with high enough severity.

Oxidative stress happens every time you exercise. People need exercise to have better health. Oxidative stress is actually a necessary part of a healthy life.

It’s more complicated than good or bad. High levels/sustained stress are definitely bad, but there’s some research to suggest that short-term oxidative stress is an important trigger for various responses in cells.
