I'm just going to ask because I think this is true but I'm not certain and nobody's talking about it. Antioxidants are BS right?
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".
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.
