We try to understand the polarization puzzle in B→ K* decays with a simple Higgs model associated with flavor changing neutral current at tree level. The new interactions can effectively reduce the longitudinal polarization |A0|2. In particular, we find that if the couplings of b-quark in different chiralities to Higgs are the same, the transverse polarization |A |2 can receive the largest contribution and its value can be as large as 30%. On the other hand, with opposite sign in the couplings, the other transverse polarization |A |2 is enhanced.
