Nutrition Myths Are Everywhere. Learn How To Spot Them

Nutrition Myths Are Everywhere. Learn How To Spot Them

Navigating nutrition can be perplexing. The abundance of information available often includes flawed, misinterpreted, or outright false details. The existence of nutrition myths can be attributed to various factors.

One contributing factor is the source of nutrition information. Many individuals who write about nutrition lack relevant educational and professional backgrounds. This absence of expertise can contribute to the proliferation of misinformation.

The fundamental principles of evidence-based nutrition, such as "eat your fruits and vegetables," may not be as attention-grabbing as sensationalized statements like "cure diseases by eating healthy vegetables." Such misinterpretations can give rise to myths surrounding the supposed miraculous properties of specific foods.

In the realm of nutrition science, ongoing research continually expands our understanding, revealing gaps in our knowledge about food and nutrition.

Deciding what to eat is a complex process influenced by various factors, including personal tastes, family preferences, cultural traditions, budgets, values, accessibility, convenience, time constraints, social pressures, and even nutrition myths. There is no one-size-fits-all approach to eating because we navigate through these multifaceted considerations.

Top 10 Nutrition Myths Debunked 

Persisting nutrition myths often stems from individuals relying on personal experiences and those of their social circles. For instance, if a particular diet yields positive results for a group of friends, human bias may lead them to believe it is universally effective. Sharing such experiences on social media about healthy fats or whole foods, while well-intentioned, is a flawed way of interpreting nutrition science and dispensing advice.

It's crucial to embrace the diverse reasons influencing our food choices, but it's equally important to exclude nutrition myths from this decision-making process. Let's learn the common nutrition myths revolving around people.

debunking nutrition myths

1) Myth: Carbohydrates are responsible for weight gain.

Reality: Weight gain is a multifaceted process, and no single nutrient, food, or food group can be solely blamed for it.

The complexity of weight gain extends beyond the consumption of a specific food or food group. Generally, an excess of calories compared to what the body needs for weight maintenance leads to weight gain. However, various other factors influence body weight.

An optimal health diet encompasses a variety of carbohydrate-rich foods, as carbohydrates serve as the body's preferred energy source. When selecting carbohydrates, focus on their quality. Opt for carbohydrates that not only provide energy but also offer additional nutritional benefits, such as fiber, vitamins, and minerals. Complex carbohydrates with fiber are digested and absorbed more gradually than simple carbohydrates.

Examples of high-quality carbohydrates include whole grains, fruits, vegetables, beans, and lentils.

2) Myth: A vegetarian or vegan diet lacks sufficient protein.

Reality: Numerous vegetarian foods are rich in protein, and with careful planning, individuals following vegetarian or vegan diets can meet their protein requirements.

There are various forms of vegetarianism, with some including eggs, dairy, and/or fish in their diet, while others, such as vegans, rely solely on plant-based foods.

Protein-rich plant sources encompass beans, lentils, soy products (tofu, edamame, tempeh), nuts, and seeds. Additionally, whole grains contain protein, though they may not be categorized as a primary source of protein or a designated protein food.

Vegetarians should incorporate protein sources into each meal and snack. Seeking guidance from a doctor and a registered dietitian about individual protein needs is recommended.

3) Myth: All foods containing gluten are detrimental to health. 

Reality: A gluten-free diet is necessary only for specific individuals.

foods containing gluten

Gluten comprises proteins present in cereal grains like wheat, barley, and rye. Those diagnosed with celiac disease or non-celiac gluten sensitivity by a medical professional should steer clear of gluten-containing foods. Celiac disease, an autoimmune disorder, causes small intestine damage upon gluten consumption. Non-celiac gluten sensitivity mirrors celiac symptoms but isn't classified as celiac disease. In both cases, adopting a gluten-free diet aids in symptom management.

For those without these conditions, foods containing gluten can be part of a balanced diet. Prioritize nutrition by opting for whole grains over refined ones. Examples of gluten-containing whole grains are wheat berries and farro.

4) Myth: The necessity of juicing or cleansing for body detoxification. 

Reality: The body possesses inherent mechanisms for detoxification.

Claims made by juices or cleanses, asserting benefits such as weight loss, improved skin health, and toxin removal, are often unfounded. There exists no singular food or diet capable of fulfilling these promises. In fact, certain cleanses, diets, and supplements may pose risks. Consult with your doctor and registered dietitian before incorporating supplements or adopting a specific diet.

The belief that specific foods, beverages, or diets are imperative for detoxification is misguided. Our body inherently performs detoxification processes. Primarily, the liver and kidneys play crucial roles in eliminating waste, maintaining hydration, and processing substances like medicine and alcohol. Additionally, the lungs and skin contribute to detoxification.

Optimal overall health is best achieved through a diet abundant in vegetables, fruits, legumes, whole grains, and lean protein. While other foods can be included, they should be consumed in smaller amounts and less frequently.

5) Myth: Snacking Equals Unhealthy Eating. 

Reality: Snacking Can Be a Healthy Component of Eating Habits, Even During Weight Loss Endeavors.

A balanced meal comprising carbohydrates, protein, and fat typically sustains satiety for about 3-4 hours, depending on individual needs and the meal's size and composition. However, many individuals have longer intervals between meals.

Snacking serves to stave off hunger pangs and maintain energy levels throughout the day. Opt for nutritious snacks containing both protein and a fruit or vegetable. Examples include apple slices with peanut butter, berries paired with a hard-boiled egg, carrot sticks with roasted edamame, or celery sticks accompanied by hummus.

Snacks consisting solely of carbohydrates, such as pretzels, are rapidly digested, potentially leading to quick hunger resurgence and subsequent overeating during the next meal or snack time. Conversely, a balanced snack containing protein, carbohydrates, and fiber digested more slowly, promoting prolonged satiety.

Incorporating fruits and vegetables into snacks is advantageous, as many individuals struggle to include them in their main meals. Snacks provide a convenient opportunity to incorporate additional servings of fruits and vegetables into one's diet.

6) Myth: Home cooking is excessively time-consuming. 

Reality: With proper planning, a well-equipped kitchen, and the selection of uncomplicated recipes, preparing weeknight meals can be a breeze. Opt for recipes requiring less than 30 minutes, like the Grilled Cauliflower and Chicken Dinner or the Eat Your Greens Frittata. Make larger quantities and freeze portions for later use, making weeknight dinners just a matter of reheating. Streamline the process with wholesome convenience foods like pre-cut vegetables or pre-cooked brown rice. Explore additional speedy meal ideas in the Heart & Stroke recipe file.

7) Myth: Avoid consuming any food after 7 p.m., including a single grape. 

Reality: Weight gain or hindrance in weight loss may result from late-night snacking, but it's not solely determined by the clock. The crucial factor is the reason behind your eating habits. Evening eating is often driven by factors like habit, boredom, or cravings rather than genuine physical hunger.

8) Myth: Certain foods, such as grapefruit, cayenne pepper, and vinegar, have the potential to promote fat burning.

Reality: Despite claims about fat-burning properties in certain foods like grapefruit, cayenne pepper, or vinegar, there is no scientific evidence to support the idea that these foods accelerate weight loss or boost metabolism significantly. Diets centered around specific items, such as those mentioned, are overly restrictive and lack essential nutrients. Moreover, they tend to be unsustainable, with any initial weight loss likely stemming from calorie reduction and often leading to regained weight once the diet is discontinued.

9) Myth: To reduce sodium intake, simply removing the salt shaker from the table is insufficient.

Reality: The 2020–2025 dietary guidelines for Americans advise a daily sodium limit of no more than 2,300 milligrams, yet the average American consumes around 3,400 milligrams. The issue extends beyond table salt, as a significant portion of excess sodium comes from additives in processed and restaurant foods. A more effective approach is to minimize processed food consumption and prioritize fresh, home-cooked meals.

10) Myth: Weight gain is associated with full-fat products.

Reality: The era of the fat-free and low-fat diet trend, prevalent in the 80s and 90s, is now outdated. However, some individuals still harbor a fear of consuming fat. This fear is unwarranted, as fat serves essential functions like safeguarding our organs, maintaining cell membranes, promoting growth and development, and facilitating the absorption of vital vitamins.

It's crucial to recognize that not all fats are the same. Opt for heart-healthy unsaturated fats, such as olive oil, canola oil, nuts, nut butter, and avocados, over those high in saturated and trans fats. Examples of the latter include fatty meats and high-fat dairy products.

White Bread vs. Whole-Wheat Bread

The most common myth around people is that white bread increases fat and wheat bread is a good healthy choice. Is it true? Let's understand the table below.


White Bread

Whole-Wheat Bread


Refined flour, water, yeast

Whole wheat flour, water, yeast, and sometimes additional grains/seeds

Fiber Content



Nutrient Density



Vitamins and Minerals


Higher (especially in B vitamins, iron, and magnesium)




Blood Sugar Impact

Higher glycemic index

Lower glycemic index


Maybe less filling

Tends to be more filling

Health Benefits

Fewer due to lower fiber and nutrient content

Higher fiber and nutrient content may contribute to better heart health, digestive health, and weight management

Remember that individual dietary needs and preferences can vary, and moderation is key. Whole-wheat bread is generally considered a healthier option due to its higher fiber and nutrient content, but it's essential to consider your overall diet and health goals.
