Re: No safe level of anything
There is considerable evidence that increased levels of fruit and vegetable give improved medical status, improve internal biome and protection from a lot of disease etc.
I was only discussing this with the wife yesterday. I love lots of vegetables but my gut is decidedly happier with a "bad" diet. There's a reason why every school kid knows the song "Beans, Beans good for the heart, the more you eat the more you F**t" and it isn't just beans that have that effect, whole swathes of the vegetable family have a similar effect.
