Could I please not receive emails from a certain doctor?

Could I please not receive emails from "Dr C. Nossel" about what I buy at Woolworths...?

As far as invasion of privacy goes, Vitality is crossing the line here.

I get most of my meals at work. What I buy at Woolworths, why I buy it, or for whom it is - those things are not "Dr C. Nossel"'s business.

Give me my points when I buy HealthyFood items and leave it at that.
