Breastfeeding decreases risk of developing psoriasis

[Fred]

In the uk right now many babies are breastfed but when I was born it was much less usual, it was seen as normal to go straight to formula.
Apparently only about 25% of us were breastfed back then so wouldn’t this suggest the incidence of psoriasis would be much higher in older age groups than in babies born more recently?

Yes.. I agree that would be more logical then. It should be possible to see that in the generations.  I am from a generation that was breastfed for a long time,

Money would have played a part in my time, breast milk was free I don't even know if there was formula's when I was born but my family wouldn't have been able to afford them if they were.
