Eating properly, i.e. eating healthy, doing sport and having the rest of everyday life under control - all of it together is not that easy.

And what of all these trend diets and nutrition tips are really useful?

WELT editor Britta Sieling tries to find out exactly that in regular seven-day tests.

You can see whether and how this works in their video diary.

This episode is about: Clean Eating.

An excerpt from the transcript:

Britta:

Can I also use frozen food or sugar-free canned food, such as beans that are pre-cooked?

Where is the limit then?

So where does clean eating end?

Prof. Dr.

Hans Hauner:

Yes, for the clean-eating protagonists this is of course the fall of man.

But now from my point of view no problem at all if you also buy and use frozen food.

It's really clean.

That is really optimally harvested, stored, and then in a certain way is really fresh.

All the important nutrients are well preserved.

The composition of clean eating is certainly healthy and almost corresponds to the 10 rules of the DGE.

But it's a lot of little rules that in some ways don't really make sense.

It's more the philosophy and the ideology behind it.

But what then means that you have to look very carefully: It is a relatively large effort.

You also have to spend a lot of money to always get fresh vegetables and fruits.

And that in itself is my criticism: It is relatively complex.
