What is healthy?
What are we teaching our children it looks like?
Nearly two-thirds of the calories consumed by American children come from ultra-processed foods.
It is time we understand how we got here.
Understand Real Food. Question What Became Normal. Change What We Pass Down.
64.8%
of calories consumed by children ages 6–11 come from ultra-processed foods.
What are our children actually eating?
Ages 1–556.1%
Ages 6–1164.8%
Ages 12–1863.0%
Ages 19–3954.4%
Ages 40–5952.6%
Ages 60+51.7%
0% to 80%
Is this getting better?
Change is possible. Ultra-processed food consumption among young people has declined from its recent peak. It still represents nearly two-thirds of calories.
Percent of calories, youth ages 1–18. Axis runs from 0 to 80 so the level stays visible.
Most of us are born healthy. Somewhere along the way, we become unhealthy. Then health is sold back to us.
If most people begin life healthy, what happens between childhood and adulthood?
Food. Environment. Culture. Convenience. Marketing. Habits. Access. Information. Family. Economics.
We do not have a shortage of health information. We have a problem turning information into decisions people can actually use. Vowels.org exists to keep asking those questions.
Who told us this was healthy?
A health belief can become a product. A product can become normal.
Corn flakes, bacon and eggs, “low fat,” vegan labels, and protein snacks each have a history. The point is not a villain. The point is to separate what happened, what people believed, who benefited, and what the evidence says now.
What happens as children grow?
About one in five U.S. children and adolescents ages 2–19 has obesity. The share is 14.9% at ages 2–5 and 22.1% at ages 6–11. These figures describe weight status. They do not prove a single cause.

Which breakfast did we learn was normal?
This is a way of looking, not a scored contest. The numbers on a real package belong on the label. Vowels teaches people how to read them.
Breakfast A
- Sugary cereal
- Flavored milk
- Packaged breakfast bar
Breakfast B
- Eggs
- Fruit
- Oats
- Water
Ask of each one: Can you name the ingredients? How long does it take? What does it cost this week? What does a child learn is a normal morning?
Read a labelHealth is generational
We inherit more than genetics. We inherit recipes, routines, beliefs, shopping patterns, celebrations, portion expectations, and ideas about what food is supposed to look like. Inherited does not mean permanent.
- Grandparents' environment and traditions
- Parents' habits, convenience, and marketing
- Children's environment and what becomes normal
- Adult behavior
- The next generation
- Awareness
What changed together?
Food spending, eating away from home, sweet drinks, portion sizes, and advertising moved over the same decades. Understanding why requires the whole system. Vowels will put a year on this timeline only when that year has a public source.
- What was cooked at home?
- What became the convenient default?
- What was marketed to children?
- What do children see adults eat now?
The conversation has changed
If the guidance is clearer, how do families use it?
The Dietary Guidelines for Americans, 2025–2030 emphasize real, nutrient-dense foods and home-prepared meals, and tell people to avoid highly processed salty or sweet foods and sugar-sweetened beverages. The public toolkit pictures that as protein foods, dairy, vegetables, fruits, healthy fats, and whole grains. RealFood.gov describes the guidance as flexible across cultures and kitchens. Clearer guidance still has to be understood.
