If you’re giving your kids breakfast cereal and thinking you’re doing a good thing, you may want to think again. According to a new report, some are no better feeding them cake and cookies.

After the Environmental Working Group checked the content of 84 popular cereals, it found Kellogg’s Honey Smacks had a whopping 56 percent sugar by weight, giving it the dubious top honors on the group’s list of the 10 worst kids’ cereals.

In fact, one cup of Kellogg’s Honey Smacks has more sugar than a Hostess Twinkie, and a cup of 44 other children’s cereals have more sugar than three Chips Ahoy! Cookies.

Noted NYU nutrition professor Marion Nestle said, “The cereals on the EWG highest-sugar list are among the most profitable for their makers, who back up their investment with advertising budgets of $20 million a year or more. No public health agency has anywhere near the education budget equivalent to that spent on a single cereal. Kids should not be eating sugar for breakfast. They should be eating real food.”

So which cereals will put your kids on the express train to a sugar high? Based on percent of sugar by weight:

  1. Kellogg’s Honey Smacks — 55.6 percent
  2. Post Golden Crisp — 51.9 percent
  3. Kellogg’s Froot Loops Marshmallow — 48.3 percent
  4. Quaker Oats Cap’n Crunch’s OOPS! All Berries — 46.9 percent
  5. Quaker Oats Cap’n Crunch Original — 44.4 percent
  6. Quaker Oats Oh!s — 44.4 percent
  7. Kellogg’s Smorz — 43.3 percent
  8. Kellogg’s Apple Jacks — 42.9 percent
  9. Quaker Oats Cap’n Crunch’s Crunch Berries — 42.3 percent
  10. Kellogg’s Froot Loops Original — 41.4 percent
