Horace Fletcher, a charlatan, with a harmless but inconvenient theory convinced the world that each bite should be chewed 32 times. It slowed us all down and couldn't be all bad. Despite advances in nutrition education, diet madness still grips us. We regularly fall prey to ridiculous diet fads with no scientific evidence to support them such as the 3-day diet, the cabbage soup diet, the negative calorie diet, the Beverly Hills diet, the Zone diet and various combining diets.
Perhaps the Health Fairy was educating the children about the spurious health claims being made by food companies such as Quaker Oats claiming to curb nervousness and constipation, Fleischmann's yeast to sooth frayed nerves and loosen the bowels and the "Chicken Dinner" candy bars so called because it provided satiety, like a chicken dinner.
Worrisome also to the nutritionists of the day, the twenties were the golden age of candy bars some of which are still around: Baby Ruth, Milky Way, Butterfingers and Oh Henry, only one cent!
Cooler sweets hitting the market included Good Humor bars, Eskimo Pies and Pospsicles. The grocery store was laden with temptation and danger. I guess "Yea Bo" was some sort of cool address form, like today's "Hey Dude". `
