My 11-year-old son is not the healthiest eater. He is very finnicky and all but detests vegetables. In an effort to get him to gain weight (he is a bit slimmer than I think he should be), I have been making him milkshakes with Ensure or Boost protein drinks blended with ice cream(chocolate chip cookie dough seems to be the favorite). He does not as a general rule eat sweets. The milkshakes is pretty much the only "junk" he consumes on a regular basis. My question is, am I putting him in danger of contracting diabetes with the daily shakes? Diabetes does not run in our family but I still want to make sure I'm not putting him at risk.
