I thought some of the tips were interesting which is why I posted it. For example, the cutting board thing. I had never thought about it but obviously if you are using a plastic cutting board and cutting food on it with a knife, you are almost certainly getting plastic in your food.

Yeah 4 of the 5 are just variations of "don't put food and drink in plastic containers".

But I've got another one: use rock salt instead of sea salt. This might not be feasible; most or all salt I see in sea salt, but it seems fairly obvious to me that rock salt is unlikely to contain any plastic, whereas sea salt is likely to contain plastic.
