I really miss a 500 gr Nature skimmed yogurt. The budget 500g yoghurt has 1.7g fat and is certainly already reduced.
But in my opinion, a 500 g low-fat yoghurt with 0.2 or 0.1 g fat is simply missing.
This is also readily available everywhere in Germany.
I would ask you to check and hope that such a product will soon be available in Migros.
