All Fats Are Bad for Your Health
The 1990s branded fat as the villain, and many Americans still believe this outdated myth. However, nutrition experts now know that all fats aren’t created equal. While animal fats high in saturated content link to cardiovascular disease, healthier monounsaturated and polyunsaturated fats found in fish, avocados, olives, and nuts can actually lower your risk of heart disease and death.
This misconception led to decades of fear around healthy fats, when unsaturated fats provide vital nutrients and help maintain good cholesterol levels. Think about it this way: your brain is roughly sixty percent fat, so completely avoiding this macronutrient makes about as much sense as a car running without oil.
The food industry capitalized on fat phobia by creating thousands of “low-fat” products packed with sugar instead. Products labeled ‘low fat’ may look healthy at first glance, but they often contain added sugars or salt to compensate for flavor losses. Your best bet is reading ingredient lists rather than trusting front-of-package claims.
Eating Small, Frequent Meals Boosts Your Metabolism
This myth feels so logical that it’s become nutrition gospel. The idea suggests that eating smaller, frequent meals could boost metabolism so you burn more calories, but studies show that splitting calories into six meals rather than three does not help with daily energy expenditure or weight loss.
Research comparing participants who ate six small meals versus three large meals showed no metabolic advantage for the frequent eaters. What separated them from the three-meal group was higher levels of hunger and increased desire to eat. University of Colorado researchers found that those eating smaller, more frequent meals ended up feeling hungrier than counterparts who ate less often.
Unfortunately, there’s little scientific evidence that eating small, frequent meals boosts metabolism. Spreading meals throughout the day might keep you from getting too hungry and overeating. While eating six small meals slightly increases metabolism six times, eating three larger meals can result in similar overall effects through three proportionally larger boosts.
The 2020 Dietary Guidelines Advisory Committee focused on frequency of eating and found insufficient evidence to determine the relationship between eating frequency and body composition or risk of overweight and obesity.
Seed Oils Like Canola Are Toxic and Cause Inflammation
Social media influencers have declared war on seed oils, claiming they’re inflammatory toxins poisoning our food supply. Despite posts claiming canola oil, sunflower oil and other seed oils are toxic, science doesn’t back that up, with very clear evidence showing they’re beneficial.
Canola oil is very low in saturated fat and high in healthy monounsaturated fats, omega-3s and phytosterols, which reduce cholesterol absorption. A 2020 review found that canola oil lowered cholesterol and improved cardiovascular risk factors. Other seed oils, including soybean oil and sunflower oil, are also healthy options.
Studies show that omega-6 fatty acids can reduce LDL cholesterol and improve blood sugar control, which benefits cardiovascular health and diabetes management. Seed oils, when part of a balanced diet, don’t cause chronic diseases, and dietary guidelines recommend using these oils to replace saturated fats.
The fear stems from misunderstanding how our bodies process different fats. Your liver doesn’t care if the healthy fat came from an olive or a sunflower seed – it uses what it needs and processes the rest efficiently.
Fresh Fruits and Vegetables Are Always More Nutritious Than Frozen
While there’s a longstanding belief that “fresh is best,” research suggests that frozen, canned, and dried fruits and vegetables can provide just as much nutrition as fresh produce. This revelation shocked many health-conscious consumers who’d been paying premium prices for fresh options.
Both fresh and frozen fruits and vegetables are nutritious choices and count towards your recommended daily intake. Fruits and vegetables often travel great distances and start losing nutritional value before reaching our plates. Meanwhile, frozen varieties are typically picked at peak ripeness and flash-frozen, locking in nutrients.
Frozen options can be a money saver and ensure fruits and vegetables are always available at home. However, reading nutrition labels to check for added sugars, saturated fats, and sodium helps find products with minimal additives.
The “fresh is best” mentality probably developed because we associate freshness with quality. Yet a frozen blueberry picked at peak ripeness often contains more antioxidants than a “fresh” one that traveled across continents and sat in storage for weeks.
You Need to Avoid Gluten Unless You Have Celiac Disease
Unless you have celiac disease or gluten intolerance, you don’t need to avoid gluten, which is the protein found in wheat, barley and rye. Whole-wheat products have great nutritional benefits, including essential B vitamins and fiber.
The low-carb diet trend has given carbohydrates, including fruit and whole grains, a bad reputation. Individuals following this diet had weight loss success, but anyone eliminating highly processed carbohydrates like chips, cookies, white bread and buttered potatoes would expect similar results.
Any diet eliminating an entire food group gets a red flag as you’ll likely miss out on vital nutrients. The gluten-free trend took off partly because people felt better after eliminating processed foods, not necessarily because gluten was the problem.
Consider this: humans have been consuming gluten-containing grains for thousands of years. Unless you have celiac disease or gluten intolerance, you don’t need to avoid gluten. The issue isn’t the gluten itself, but often the highly processed foods containing it.
Carbohydrates Make You Gain Weight
Carbohydrates are often seen as the enemy, but they’re not the villain when it comes to weight gain. Like anything, it’s all about balance and choosing the right kind. Weight gain happens when we eat more calories than we burn, whether they come from carbs, protein, or fats.
Choosing high-fiber carbohydrates like whole grains, fruits, and vegetables while limiting added sugars can help with feelings of fullness and is linked to more positive health effects, including lowering risk of heart disease and type 2 diabetes. Cutting out carbs can mean missing essential nutrients like B vitamins, calcium, and dietary fiber. It can also lead to higher intakes of saturated fat and a negative relationship with food.
The anti-carb movement gained momentum because people saw quick results from eliminating processed carbs. Yet there’s a massive difference between a donut and a sweet potato, even though both contain carbohydrates. Your body needs carbs for energy, especially your brain, which runs almost exclusively on glucose.
Quality matters more than quantity. The rise in chronic diseases is more likely linked to overconsumption of foods high in saturated fat, salt and sugar, and a more sedentary lifestyle rather than carbohydrates themselves.
Eggs Raise Your Cholesterol and Harm Heart Health
This myth stems from the belief that dietary cholesterol harms heart health. Recent research indicates that your overall diet and the types of fat and cholesterol you consume matter more for heart disease risk. Many recent studies show that eggs can fit into a heart-healthy diet.
Eggs are nutritious, packed with protein, vitamins, and minerals. For most people, eating one egg per day is perfectly healthy. Just be mindful of your overall diet and consult with a healthcare provider if you have concerns about cholesterol levels.
The egg scare started in the 1960s when researchers noticed a connection between dietary cholesterol and blood cholesterol. Yet they didn’t account for the fact that your liver produces most of your body’s cholesterol regardless of what you eat. When you consume more cholesterol, your liver typically makes less.
Modern research shows that eggs contain nutrients like choline, which supports brain health, and lutein, which protects your eyes. The cholesterol in eggs has minimal impact on blood cholesterol for most people, making this once-feared food a nutritional powerhouse.
