Someone just referred to this in another thread about blueberries and milk
Blueberries and Milk Don’t Mix: Study | All Star Health

Which is a pity as they go so well with dairy. And someone suggests that maybe other issues with antioxidants from fruit and veg being neutralized by proteins. Not at all surprising (and I suspect most fruit would have been munched while picking randomly during the day, not eaten with cooked meat anyway.)

So anyway - any other good tips on food combining for maximised nutrition? Like, I'm not going to obsess over it, but might as well get the most out of things.
