Have you ever stopped to wonder if all those food rules you grew up hearing were actually true? It’s kind of shocking how many old wives’ tales about food have squeezed their way into our everyday lives. For years, you might have avoided certain foods, felt guilty about eating others, or worried about strange things happening inside your body—all because of a few persistent myths passed down from parents, teachers, and well-meaning relatives. Let’s dig into the top ten food myths you’ve probably believed since you were a kid. Some of these might surprise you, and you might even feel a little betrayed by your childhood self!
Carrots Improve Your Night Vision 🥕
Almost everyone has heard that munching on carrots will give you the eyesight of a superhero, especially at night. This idea became popular during World War II when the British government claimed their pilots ate carrots to spot enemy planes in the dark. The real reason? They didn’t want to reveal their new radar technology. While carrots are loaded with beta-carotene, which your body turns into vitamin A—important for general eye health—eating a pile of carrots won’t let you see in pitch-black darkness. If you’re low on vitamin A, carrots can help, but they won’t give you special powers. A balanced diet with various fruits and vegetables is what really keeps your vision sharp.
MSG Is Bad for You
For years, monosodium glutamate (MSG) has been painted as a villain in the world of food additives. You might have heard it causes headaches, allergic reactions, or worse. The truth is, scientific studies haven’t found solid evidence that MSG is dangerous for most people. The FDA considers it safe, and millions of people around the world eat it every day without issue. MSG actually enhances the umami flavor in dishes, making things taste richer and more satisfying. While a small number of people might be sensitive, for most, there’s no need to fear MSG in your takeout or snacks. Next time you see “No MSG” on a menu, you’ll know it’s more about marketing than actual science.
Sugar Makes Kids Hyper
It’s almost legendary: a kid eats a cupcake and suddenly bounces off the walls. But here’s the twist—science doesn’t back this up. Dozens of studies have looked for a connection between sugar and hyperactivity in children and found nothing solid. The real reason kids might seem wild after birthday cake is the excitement of the party, not the sugar itself. Parents sometimes expect sugar to make kids hyper, so they notice any extra energy and blame the treat. Sure, too much sugar isn’t great for health, but it’s not the magic switch that turns kids into mini tornadoes.
Eggs Raise Your Cholesterol
For decades, eggs were seen as a breakfast danger zone because of their cholesterol content. You might have watched your parents toss out yolks or skip eggs altogether. But more recent research shows that dietary cholesterol doesn’t affect most people’s blood cholesterol as much as once thought. Eggs are actually a powerhouse of nutrition—packed with protein, vitamins, and minerals. For most people, eating eggs in moderation won’t boost their risk of heart disease. It’s the bacon and butter-laden breakfasts you might want to watch, not the humble egg.
Microwaving Kills Nutrients
Some folks insist that microwaving your food zaps away all the good stuff, leaving you with an empty shell of a meal. That’s not really true. In fact, microwaving often preserves more nutrients than boiling or frying because it cooks food quickly and usually uses less water. Vitamins like C and B, which are sensitive to heat and water, actually stick around better in microwaved veggies. If you want to keep your food nutritious, try microwaving with just a splash of water and keep cooking times as short as possible. So, your microwave isn’t a nutrient thief—it might even be your kitchen’s secret weapon.
You Shouldn’t Swim After Eating
Did your parents ever make you wait an hour after lunch before diving back into the pool? The idea was that swimming with a full stomach would cause cramps and maybe even drowning. It sounds scary, but there’s no real evidence to support this. While digestion does redirect some blood to your stomach, it doesn’t leave your arms and legs powerless. Most people can swim just fine after eating, though you might feel a bit sluggish if you’ve stuffed yourself. If you’re comfortable, it’s safe to swim, whether you just ate or not.
Brown Eggs Are Healthier Than White Eggs
This is one of those myths that seems to make sense: brown rice is better than white rice, so brown eggs must be better than white eggs, right? Not quite. The color of an eggshell depends on the breed of the hen and has nothing to do with nutrition. Brown and white eggs are nearly identical in protein, vitamins, and minerals. Some people think brown eggs taste different, but that’s usually just in their heads. The only real difference might be the price—brown eggs can cost more, but you’re not paying for extra health benefits.
Gum Stays in Your Stomach for 7 Years
Swallowing gum has terrified kids for generations. The story goes that it sticks around in your stomach for seven years, refusing to budge. The truth is, your digestive system can’t break down gum, but it also doesn’t let it hang out forever. Gum passes through your system just like other things your body can’t digest and exits within a few days. It’s still best not to make a habit of swallowing gum, since it could cause a blockage if you swallow a lot. But if it happens once in a blue moon, you’re not doomed to carry it around for years.
Alcohol Cooks Off Completely When Heated
People often assume that adding wine, beer, or liquor to a dish and cooking it guarantees all the alcohol disappears. It’s a comforting thought, but it’s not entirely true. Depending on how you cook, a decent amount of alcohol can stick around—sometimes up to 25% or more. Some methods, like flambé or a quick sauté, leave even more. If you need to avoid alcohol entirely, it’s important to know that “cooking it off” doesn’t always make a dish alcohol-free. The longer you cook and the higher the heat, the less alcohol remains, but it never goes down to zero instantly.
Eating Fat Makes You Fat
For years, “fat” was a dirty word. Diet books, magazine covers, and food labels all warned us that eating fat would lead straight to weight gain and health problems. But fat isn’t the enemy. Your body needs healthy fats for energy, cell growth, and absorbing vitamins. Foods like avocados, nuts, fish, and olive oil are full of the good kind. The real culprit behind weight gain is eating more calories than your body burns—regardless of whether those calories come from fat, carbs, or protein. Eating fat in moderation can actually help you feel full and satisfied, which might help you eat less overall.
