What Are the Most Commonly Misunderstood Foods and Nutrients?
Nutrition is rife with misconceptions, and to shed light on the truth, we've gathered insights from dietitians and industry professionals, starting with a Founder and Dietitian's perspective on coconut oil. Alongside expert opinions, we've included additional answers that address common confusions, such as the myths surrounding eggs and cholesterol. From clarifying the role of misunderstood nutrients to unveiling the umami truth about MSG, here's a compilation of clarifications to better inform your dietary choices.

Clarifying Coconut Oil Misconceptions
One commonly misunderstood food item is coconut oil. Many people think coconut oil is unhealthy due to its high saturated fat content. However, coconut oil contains medium-chain triglycerides, which are easily digested and converted into energy. Coconut oil does not increase LDL 'bad' cholesterol like other saturated fats. I explain to clients that coconut oil can be part of a healthy diet when consumed in moderation. The saturated fats in coconut oil may actually help boost HDL 'good' cholesterol levels and improve other markers of heart health when consumed as part of a well-rounded diet. Coconut oil can also be a good substitute for butter or vegetable oils in cooking and baking.
Understanding Sea Salt and Sodium
In my experience as a dietitian, one commonly misunderstood nutrient is salt, specifically sea salt. Many of my patients come in believing that sea salt is significantly healthier than regular table salt and therefore use it liberally in their cooking and seasoning. One patient even mentioned she 'dumps' it on her food to 'get extra nutrients.' However, it's crucial to clarify that while sea salt does contain trace minerals not found in table salt, the basic nutritional impact regarding sodium content is the same. Excessive intake can still lead to high blood pressure and other health issues.
To address this misconception, I focus on education, explaining the similarities in sodium content between sea salt and table salt, and discuss the importance of moderation. We work on adjusting their palate gradually, reducing salt intake slowly to make the change sustainable. Through consistent dietary adjustments, many of my patients have successfully lowered their salt consumption, which in turn has positively impacted their blood pressure.
Carbs and Fats are Vital Nutrients
I have to mention two—carbs and fats—because they have an equally bad reputation that is 100% scientifically unfounded.
Many people fear carbs due to misconceptions about weight gain. However, carbohydrates are a vital source of energy for the body. Your brain can't work without carbs, and also, you can't be physically active without fuel. Instead of demonizing carbs, I emphasize the importance of portion control and timing.
Fat is another nutrient that often gets a bad rap, largely due to the misconception that all fats are unhealthy. This is a dangerous misconception because fats are essential for various bodily functions, including hormone production and nutrient absorption. I educate clients about the distinction between healthy fats (nuts, seeds, avocados, fatty fish, etc.) and unhealthy fats (trans fats and excessive saturated fats found in processed foods and fatty meats).
Egg Cholesterol Myths
Eggs have long been at the center of a nutritional debate, with many fearing their high cholesterol content could lead to heart problems. However, recent studies suggest that for most people, the cholesterol in eggs doesn't significantly affect blood cholesterol levels. Instead, eggs are praised for being a high-quality protein source, containing all nine essential amino acids.
They are also packed with nutrients beneficial for eye health, like lutein and zeaxanthin. Are eggs part of your diet? Consider their nutritional benefits the next time you plan a meal.
Debunking Soy Phytoestrogen Fears
Soy has been a controversial food item due mostly to the presence of phytoestrogens, which are plant compounds with a weak estrogen-like effect. While some worry about the hormonal impacts of soy, numerous research studies have indicated that moderate consumption is safe and does not disrupt the endocrine system. In fact, soy is a heart-healthy source of protein, fiber, and essential fatty acids.
Understanding these benefits can offer a balanced view of soy's place in a healthy diet. Remember to include diverse protein sources in your meals for a well-rounded nutrition plan.
Gluten Necessity Versus Trend
Gluten, a protein found in wheat, barley, and rye, has become widely misunderstood, often being eliminated from diets unnecessarily. While people with celiac disease must avoid gluten, others may not benefit from cutting it out of their diet. Gluten itself isn't inherently bad; it's responsible for the elasticity in dough and is in many staple foods.
Educating oneself on who actually needs a gluten-free diet is important, as whole grains that contain gluten are rich in fiber and various vitamins. Next time you shop for bread or pasta, take a moment to consider if gluten-free options are truly the best choice for you.
Unveiling the MSG Umami Truth
Monosodium glutamate, commonly known as MSG, has been the subject of myth and misinformation, leading some to avoid it due to fears of it being harmful. However, scientific consensus asserts that MSG is safe to consume in regular dietary amounts. It's a flavor enhancer that has been used for more than a century, especially in Asian cuisine, to provide the savory taste known as umami.
Understanding the role of MSG in cooking can enhance the taste experience without fear. Be open-minded and try a dash of MSG in your next dish to explore its unique flavor.
Lactose Intolerance and Alternatives
Dairy products are often avoided by those who experience lactose intolerance but are overlooked for their nutritional value, especially as a source of calcium. Besides calcium, dairy products offer vitamins D and B12, potassium, and protein. While not everyone can tolerate lactose, there are numerous lactose-free dairy options available.
Additionally, dairy isn't the only source of these nutrients, and those who don't consume dairy can find alternative foods rich in the same beneficial components. Consider the role of dairy or its alternatives in meeting your nutritional needs and opt for fortified products if necessary.
