We all ate lots of snacks when we were kids. This is an almost universal experience. Given how most of our parents often restricted consumption of such snacks, it made those munchies all the more appealing. Your mileage will vary depending on how strict the adults in your lives were. My grandma, for example, always said that they were carcinogenic. Yes, every single one of them. Now that I'm older, I realize that there may be some truth that, not as far as she would have had me believe, but enough to know that many of those snacks were bad-for-ya.
Kaka is probably one of them. Made by Kinos Food across the causeway, this supposed corn-based snack came in chicken, chocolate, and coconut flavors, with chicken being the most popular simply because that shit was salty as fuck. And when you're a kid, that's sensory gold. Coupled with a bonus item inside each packet such as a small plastic toy or an instant rub-on tattoo and you have a winning recipe to sucker kids in. Other similar snacks include Chickadees, Super Rings, and Twisties, all of which are still available today. Twisties are, in fact, very much alive in Singapore stores. You may have to head over to Johor to get the others (they don't contain extra items anymore) and after having sampled some in recent years, I believe they altered the formula for more modern tastes (i.e. they're not as salty).
Two other popular snacks from the 80s were Ding Dang and Tora. Now these two I wholly agreed with my grandma. Essentially chocolate coated biscuit balls, I was absolutely convinced that the ingredients were all synthetic. That's why you don't see them in the series. Also, like many other IP violations back in those ignorant/lawless times, I am pretty sure the manufacturers did not get a license from Fujiko F. Fujio to use Doraemon in its likeness. Again, it was the supplemental toy inside each box that got kids coming back for more. Hell, I bought some just to toss the balls and keep the figurines.
What about you? Do you remember snacks from your childhood that were bad-for-ya?
