How cereal became
a multivitamin
Leighana Luther
My great great grandma Virginia died of a vitamin deficiency in 1924. For most of her life, she lived on an active farm in Louisiana, growing corn and cotton.
Corn was a central part of the diet for rural Southerners. My mom remembers how her grandma and great uncle (Virginia’s kids) would dunk cornbread into a cup of buttermilk and eat it straight out with a spoon.
Virginia had pellagra, known for causing four ominous D’s: diarrhea, dermatitis, dementia, and death. She holds her hands behind her back in a grainy black and white photo, probably because of the pellagra rash.
When her husband retired from farming around 1920 and began working as a store merchant, the family likely began to buy cornmeal from the store, rather than use their own harvest. A new commercial milling process made cornmeal shelf stable, but unwittingly removed most of the vitamins.
Scientists didn’t fully understand it until 1937, but Virginia was missing niacin (vitamin B3).
As vitamins were eventually identified and understood, public health organizations suggested adding them to staple food sources.
In 1940, the Committee on Food and Nutrition recommended fortifying flour with key nutrients like thiamin, niacin, riboflavin, and iron. During World War II, the US was influenced by the British army’s decision to only purchase fortified flour, and followed suit.
Eating fortified food became a patriotic duty. Citizens were to stay healthy and strong to support a country at war.
By the 1950s, too late for Virginia, fortified foods banished pellagra and other vitamin deficiencies.
To understand how cereal comes into play, we have to go way back.
The Battle Creek Sanitarium was a palatial spa-like facility.
It was complete with medical offices, lodging, an indoor palm garden (in Michigan of all places!), a gymnasium, and many pools.
The sanitarium's mission was to provide the newest array of medical treatments, from guided diet and exercise to water therapy and Swedish massage.
Doctors could send patients here to heal from just about anything (although I doubt it took much convincing).
The director, Dr. John Harvey Kellogg, had a round face and gentle smile, yet a firm posture and sharp nose. He wrote passionately to educate the public about health. In many photos, he sports a large mustache.
He was also a racist prude. His entire estate was left to the eugenics organization he founded, the Race Betterment Foundation.
Notably, we owe cereal’s existence to him being anti-sex. He advocated for a bland diet to avoid sexual arousal, and believed a person who eats stimulating foods like coffee, meat, and spices, “might as well try to fly as to be chaste in thought.” In this paradigm, Kellogg invented cereal flakes for his guests in 1898.
The original cereal flakes were plain, so when his brother, the eventual Kellogg Company founder, proposed adding sugar, it led to a serious feud.
He would turn in his grave if he learned about Froot Loops.
Shelf stable, tasty cereal is an ideal vehicle for fortification. And it can be a lifeline.
Whether it's due to medical conditions, allergies, neurodivergence, using SNAP, or living in a food desert, some people have a limited diet. Cereal can act as a multivitamin, filling in nutritional gaps, without the need to purchase supplements. Simply add milk and you’ve got a nutritious meal with all the main macros, plus micronutrients.
Of course, most breakfast cereals are loaded with sugar.
Phrases like "honey-roasted," "frosted," "now with marshmallows" (in the cereal fanatic world, we call those marbits), "fruity," "chocolatey," and "cookie-flavored" bejewel the boxes.
They’re sweet, no denying that.
As a kid, my mom used to hand me a chocolate chip for each dose of medicine I took. Sure, the excess sugar isn’t ideal, but a spoonful of sugar does help the medicine go down.
I'll admit, we can do better. Studies have shown breakfast cereal marketed to children has gotten less healthy.
From 2010-2023, fat, sodium, and sugar content went up, while fiber and protein content went down. Compared to similar countries, American cereal is the highest in sugar and sodium.
Cereal-fiends can balance out the meal by going for a less sugary cereal, adding fresh fruit, and opting for cereal mixing to get the best of both worlds. That’s when you mix an indulgent pick like Lucky Charms with a sensible pick like whole grain Cheerios.
It's been 101 years since my great great grandma Virginia died. Through breakfast cereal and other fortified foods, I get all the niacin I need without even trying.
Thanks, fortification!
