>The fact that foods such as sardines - which are rich in taurine, omega 3, calcium and vitamin D - have a clear protective effect against the onset of diabetes does not mean that taking these supplements in isolation will have the same effect.
The only way i can understand this statement it that Rizzolo doubts that anything in the sardines are actually affecting type 2 diabetes. So perhaps the oily taste is suppressing apatite for 'sweet' and decreasing the patients sugar intake (decreasing them cheating on their diet).
Anyway a 152 patients study is not very conclusive, in larger studies there may not be any effect there at all.
You might be right but what I've read of nutrition is that taking supplements is thought to be quite different than eating a whole food. Taking Vitamin C tablets is different than eating an orange because of all the other things that are in an orange. Or what's in spinach or kale or blueberries or sardines. I think that's the point she's making.
