He probably loves the taste of it (in dishes),
so that he gladly believes its so healthy.
Yes, it contains a number of potent antioxidanta.
Antioxidants have their own category, but some of these fit in other categories as well.
Vitamin C, E and beta-carotene, for example, are also vitamins.
Metals usually fall in the category of minerals, and they actually have pro-oxidative properties.
And yet, both vitamins and minerals are considered healthy.
so, how is that possible?
Because its not a black or white issue (as it hardly ever is);
Antioxidants are not simply 'the good guys' and pro-oxidatives 'the bad guys'.
Processes in your body require oxidation. Oxidation is essential.
So, what you need is a balance, and your body will take care of that.
The antioxidants in garlic cannot do that for you, as they are very specific antioxidants;
they are not multifunctional, doing only good work.
They cannot eliminate the mutagens that you ingest from cooked food.
There will be some influence, but limited, and probably both good and bad.
or is everything good from garlic already provided in the other foods?
Yes, all nutrients (which are hardly present in garlic) are already abundantly present in foods.
You may consider garlic as a drug, that may do some good regarding certain illness(es).
