Flashback Friday: The Worst Meals for Tooth Decay


Under is an approximation of this video’s audio content material. To see any graphs, charts, graphics, photographs, and quotes to which Dr. Greger could also be referring, watch the above video.

Practically a half century in the past at a Senate listening to on diet, a Dr. Nizel from Tufts recommended that sugary breakfast cereals “ought to be banned in the very best curiosity for all involved, significantly youngsters”—maybe not surprisingly, since he was a professor of dental medication.

A dozen completely different meals and drinks have been ranked for his or her “cariogenic potential”—their cavity-causing potential—by implanting electrodes within the mouths of research topics to measure the quantity of acid produced within the plaque between their enamel after consuming a wide range of various things. And, the 2 breakfast cereals they examined topped the charts.

In case you drink some sugar water, the pH in your enamel plunges inside minutes into the acidic hazard zone, and stays there for an hour, consuming away at your enamel. Caramel is worse. It sticks to your enamel, so stays longer, down deeper within the acid zone. However, try the breakfast cereals: goes down and stays down, even two hours later.

We’ve recognized concerning the cavity-causing “potential of presweetened breakfast cereals” for many years. A dozen such cereals have been put to the check to measure the extent of tooth-dissolving acid produced by the pressure of micro organism that causes cavities. As one would possibly count on, “the [cavity-generating] potential was discovered to be associated on to the sugar content material of every cereal”—although Frosted Mini-Wheats was an exception. Regardless of having 40 p.c much less sugar than cereals like Froot Loops or Frosted Flakes, Frosted Mini-Wheats triggered the best calcium demineralization—rating second solely to the now defunct “Powdered Donutz” in cavity-causing potential. A research of twenty-eight completely different cereals concluded that “Unquestionably, the sugar concentrations in these twenty-eight cereals are sufficiently excessive to qualify them as dentally harmful.”

Desirous to be good company residents, Common Mills took their Tremendous Sugar Crisp, which was 44 p.c sugar, and diminished the sugar…font measurement. Then, caring about youngsters’s well being a lot, they eliminated sugar altogether…from, the title….

Kellogg’s cares, too. Although Sugar Smacks is, apparently, the place “house power comes from,” it doesn’t sound as healthful as Honey Smacks; similar cereal, more healthy title. They did take away sugar from Corn Pops and Frosted Flakes; I imply, effectively, from the entrance of the bins.

And Cookie Crisp? I believe the truth that it’s made by a pet food firm says all of it.

However, Common Mills protests: a research they did by which teenagers have been randomized to obtain free cereal delivered to their houses—or not—didn’t appear to get any extra cavities, proving breakfast cereal is innocent in your enamel. Anybody care to take a guess on the research’s deadly flaw? The children within the management group have been free to only have their mother and father purchase their sugary cereals from the shop, and so each the experimental and management teams could have been consuming the identical cereal, “with the one distinction being that the experimental group acquired its cereal free, and the management group” needed to pay for it.

What did the Common Mills researchers need to say for themselves? “Dietary controls so inflexible as to exclude the ingestion of cereals by youngsters can be troublesome, if not inconceivable.” However then, that’s not a management group!

That’s like this Kellogg’s-funded paper saying yeah, if we didn’t feed children sugar, then we may nearly eradicate cavities, however “this splendid is impractical.” So, let’s take the center floor and give you, oh, Froot Loops with marshmallows. However hey, a minimum of they’re fruit formed, or a minimum of “fruity formed.”

Observational research have additionally did not hyperlink breakfast cereal consumption with cavity prevalence although, or incidence. That is presumed to be as a result of consuming it with milk helps clear meals particles from the mouth. Although Frosted Mini-Wheats did result in the identical sugar retention within the saliva ten minutes after consumption, with or with out milk, the opposite cereals have been cleared out quicker. “[S]ugared cereals are sometimes eaten as snacks [by kids, though] with out milk.”

And, ten minutes after the ingestion of dry sugary cereals, you’re left with practically 50 occasions the sugar residue in your mouth, in comparison with swishing the sugar down in liquid kind. “[I]t is inconceivable,” concluded the researchers, “to contest the truth that frequent between-meal ingestion of [foods like high-sugar cereal] is dentally hazardous. Whether or not or not meal-time consuming of sugared cereals induce [cavities] just isn’t the purpose…as a result of [kids snack on them] between meals, they’ve a marked potential for dental hazard.”
