Frozen Fruits and Vegetables Are Not as Nutritious as Fresh Produce.
This myth stems from the belief that fresh is always better, but that’s not entirely true. Frozen fruits and vegetables are often picked at peak ripeness, then flash-frozen to lock in nutrients. Studies have shown that the nutrient content in frozen produce can be just as high, and in some cases even higher, than fresh produce because fresh items might lose nutrients during transport and storage.

Organic Is Always Better.
Organic produce may be free of synthetic pesticides, but that doesn’t necessarily make it healthier. Nutritionally, organic and non-organic foods are quite similar. Studies, including a review from Stanford University, show that there is little difference in vitamin and mineral content between organic and conventional produce. The “organic” label doesn’t guarantee fewer environmental impacts or superior nutrient profiles, as both farming methods can vary greatly in practices.

You Need to Eat Meat for Protein.
While meat is a good source of protein, it's not the only one. Plant-based foods like beans, lentils, tofu, tempeh, and faux meats are all rich in protein. A well-planned vegetarian or vegan diet can provide all the essential amino acids your body needs, disproving the myth that only meat can meet high protein demands.

Soy Will Give You "Man Boobs."
This myth likely comes from the fact that soy contains phytoestrogens, which are plant-based compounds similar to estrogen. However research shows that soy does not cause any significant changes in testosterone levels or estrogen levels in men. The amount of phytoestrogen in soy is too small to have such an impact, making soy a safe and nutritious protein source, that even provides many potential benefits.

A Bigger Caloric Surplus Equals More Muscle Growth.
While a caloric surplus is necessary for muscle growth, eating far beyond your body's needs won’t result in more muscle gain—it’s more likely to lead to fat gain. Research suggests that the body can only synthesize a limited amount of muscle each day, and consuming too many calories above that threshold doesn’t contribute to more muscle. A moderate surplus, combined with resistance training, is optimal for building lean muscle without excess fat gain. -
Seed Oils Are Worse Than Butter.
The idea that seed oils (like sunflower or canola oil) are inherently bad has gained popularity, but it’s largely based on misconceptions. Seed oils contain polyunsaturated fats, including omega-3 and omega-6 fatty acids, which are essential for heart health. While it's important to maintain a balance between omega-3 and omega-6, seed oils are not necessarily worse than butter, which is high in saturated fat. Replacing saturated fats with unsaturated fats, such as those found in seed oils, can help reduce the risk of heart disease, as supported by the American Heart Association. -
Plant Toxins and Lectins Are Harmful.
Lectins, found in foods like beans and whole grains, are often labeled as “anti-nutrients” that harm your body. However, lectins are largely deactivated through proper cooking methods. For example, boiling beans neutralizes most lectins, making them safe to eat. Many foods that contain lectins are also linked to health benefits, including a lower risk of heart disease and improved gut health.
As we’ve seen, many common beliefs—whether about frozen foods, protein sources, or fats—are often rooted in misunderstandings. By debunking these myths, we can develop a more balanced approach to nutrition, free from unnecessary fears and restrictions. The key to a healthy diet is variety, moderation, and being informed. Trust the evidence, embrace a range of foods, and nourish your body with confidence.
