Key Takeaways
- Across MyFitnessPal’s global database, bananas are the single most logged food, outranking every fruit, vegetable, protein, and packaged product, with nearly 130 million logs in the past year.
- Banana has held the #1 spot every year since at least 2018, across every age group where MyFitnessPal is used.
- Despite bananas’ reputation as a potassium powerhouse, avocados contain more potassium per serving (506mg vs. 422mg). Yet MyFitnessPal’s 2026 Nutrition IQ Survey found that Americans also significantly misestimate the avocado’s nutritional content, underscoring a broader gap between food reputation and nutritional reality.
- What people actually log, at scale and over time, reflects habit, convenience, and cultural familiarity far more than nutritional positioning.
Ask most people which fruit is highest in potassium, and they’ll say banana. It’s one of those nutrition facts so embedded in popular understanding that it rarely gets questioned. Bananas and potassium are practically synonymous. Our database says otherwise.
The Most Logged Food in the World
Across MyFitnessPal’s global food database, bananas are the single most logged food in the world, ahead of eggs, chicken breast, blueberries, avocado, and every other item in a database that spans over 20 million foods. In the past year alone, users logged bananas nearly 130 million times.
What makes that number more striking is its consistency. Banana has held the #1 position every year since at least 2018. It doesn’t vary meaningfully by age; it’s the top food logged by users 18 to 24 and by users 55 and older. It doesn’t vary by geography; banana tops the list for users in the United States and for a majority of other countries where MyFitnessPal is active. It doesn’t vary by gender; the banana is, in the most literal sense, the universal food.
The avocado, by contrast, sits at number five globally, with nearly 56 million logs in the past year. That reflects a food that has become a genuine dietary staple for millions of people. But the gap between the two is significant, and the gap in nutritional reputation is even larger.
The Banana’s Dominance Has Nothing to Do with Potassium
None of this is surprising when you consider how people actually eat. The banana is portable, affordable, requires no preparation, and fits into almost any eating pattern at almost any time of day. Convenience built the banana’s logging dominance, not potassium.
But the potassium story reveals something worth paying attention to. The banana earned its reputation as a potassium food the same way carrots became synonymous with eye health and spinach with boosting strength: one association, repeated often enough, becomes nutritional common sense. The association isn’t wrong, since bananas do contain meaningful amounts of potassium, but it obscures a specific truth. At 422 milligrams per medium banana versus 506 milligrams per medium avocado, the food most people reach for when they think ‘potassium’ actually contains less than the food they rank second.
What the Data Actually Shows
The potassium gap isn’t an outlier. It’s a pattern. MyFitnessPal’s 2026 Nutrition IQ Survey found that when Americans estimate the nutritional content of foods they perceive as healthy, accuracy drops consistently, and the avocado is a case in point. Respondents estimated avocados contain 14 grams of protein; they contain 3. They estimated 13 grams of fat; avocados contain 22. The food that actually leads the banana on potassium is also a food Americans consistently misestimate across multiple nutrients.
This is what MyFitnessPal’s logging data can reveal that a single nutrition headline cannot: not just what people eat, but the distance between what they believe about food and what the numbers actually show. At 130 million banana logs in a single year, #1 every year since at least 2018, across every age group, the banana’s dominance is built on habit, convenience, and cultural familiarity. People aren’t logging bananas because they’ve read a recent study on potassium. They’re logging them because the banana simply works.
The avocado’s rise to number five globally tells a parallel story with a different driver: a genuine shift in how people think about dietary fat and what healthy eating looks like day to day. That’s real behavioral change. But it hasn’t closed the gap with the banana, and it hasn’t corrected the banana’s potassium reputation, even as it surpasses the banana on that specific measure.
The banana has held the top spot every year since at least 2018, across every demographic where MyFitnessPal is active. That kind of consistency is about more than preference. It reflects how people actually build eating habits: around foods that are accessible, familiar, and easy to reach for, regardless of whatever nutritional story happens to be in circulation.
The gap between what you think you’re eating and what you’re actually eating is wider than you’d expect. Start tracking on MyFitnessPal and find out.
