Nutritional advice is everywhere, but how can we tell what is myth and what is fact when it comes to the foods we eat daily? With a constant stream of sometimes contradictory information, it is more important than ever to clarify what is true and adopt healthy eating habits based on reliable knowledge.
The Spread of Nutrition Myths
In our hyper-connected society, dietary recommendations circulate rapidly, often without solid scientific backing. Nutrition myths frequently arise on social media, in casual conversations, or even in mainstream media. These misconceptions can negatively influence our food choices and, over time, impact our health.
For example, how many times have we heard that eating eggs dangerously raises cholesterol, or that gluten is always bad for your health? While these claims are widespread, they do not always reflect the latest scientific findings. It is crucial to know where to find trustworthy information and to learn how to spot false food beliefs.
Developing a critical approach to nutrition information is therefore a key skill for maintaining a balanced diet. Understanding the limitations of studies, recognizing appeals to authority, and questioning sources are essential habits to help distinguish fact from fiction.
Do Eggs Really Raise Cholesterol?
Eggs are among the most debated foods. For years, they were blamed for their cholesterol content and excluded from many diets. Current scientific evidence, however, paints a much more nuanced picture. Multiple studies have shown that, for healthy adults, moderate egg consumption does not significantly increase blood cholesterol or the risk of cardiovascular disease.
Most of the cholesterol in our blood is produced by the liver, not directly absorbed from food. For the majority of people, eating six to seven eggs per week is not a problem. However, individuals with familial hypercholesterolemia or specific health conditions should seek medical advice.
Eggs are an excellent source of protein, as well as vitamins (B12, D, A) and minerals. When included as part of a varied diet, they contribute to good health without significant risk for most people.
Is Gluten Really Harmful for Everyone?
The debate around gluten has grown significantly in recent years. Some advocate for gluten-free diets as a cure-all for various ailments, but gluten is only problematic for a minority of people: those with celiac disease, wheat allergy, or non-celiac gluten sensitivity.
For the vast majority of people, gluten does not cause health problems. Grains containing gluten (wheat, rye, barley) are sources of fiber, B vitamins, and energy. Unnecessarily eliminating gluten can lead to deficiencies and an unbalanced diet.
Before removing gluten from your diet, it is advisable to consult a healthcare professional to assess whether such a change is truly necessary and to avoid nutritional mistakes.
Are Dairy Products Essential at Every Age?
Milk and dairy products are often promoted as essential for growth and strong bones due to their calcium content. However, their role in the diet depends on age, tolerance, and cultural habits.
Children, teenagers, and older adults have higher calcium needs. Dairy products are a convenient and effective source. However, other foods can also provide calcium: green vegetables, almonds, sardines, and calcium-rich mineral waters.
For adults who are lactose intolerant, it is not necessary to consume dairy at all costs. The key is to ensure adequate calcium intake from any source and to maintain a varied diet.
Sugar: Should All Carbohydrates Be Avoided?
Sugar is often in the media spotlight, blamed for many health issues. While excessive consumption of added sugars is indeed linked to overweight, diabetes, and cardiovascular disease, it is important to distinguish between different types of carbohydrates.
Complex carbohydrates (whole grain bread, legumes, brown rice, etc.) are essential for the proper functioning of the brain and muscles. They provide lasting energy and help with satiety. It is not recommended to eliminate all carbohydrates, but rather to favor minimally processed, fiber-rich foods.
Reducing the intake of sugary drinks, industrial pastries, and ultra-processed foods is a relevant goal for health, while maintaining a balanced and diverse diet.
Vegetarianism and Nutritional Balance: What to Keep in Mind?
Vegetarianism is becoming more popular for ethical, environmental, or health reasons. However, adopting a vegetarian diet requires careful attention to nutritional balance, especially regarding protein, iron, vitamin B12, and omega-3 intake.
Plant-based proteins from legumes, grains, soy, nuts, and seeds can meet protein needs if they are varied. Plant-based iron is less well absorbed, but its bioavailability increases when combined with a source of vitamin C. Vitamin B12, absent from plant foods, must be obtained through supplements or fortified foods.
Support from a healthcare professional is helpful for building a balanced vegetarian menu and avoiding deficiencies.
- Prioritize food variety every day.
- Read labels to spot hidden sugars and fats.
- Consult a professional before making drastic dietary changes.
- Avoid following trendy diets without scientific backing.
- Stay well hydrated and limit sugary drinks.
Mini FAQ on Food Myths
Q: Are "sugar-free" foods always healthier?
Not necessarily. Some "sugar-free" products contain sweeteners or extra fats as substitutes. It is important to check the ingredient list and favor minimally processed foods.
Q: Should potatoes be avoided to control weight?
Potatoes are a good source of carbohydrates, fiber, and vitamins. When eaten in moderation and prepared simply (steamed, baked), they can be part of a balanced diet.
Key takeaway: Relying on trustworthy, up-to-date sources helps you move beyond common myths and adopt a diet that truly meets your needs, without falling for popular misconceptions.

How to Evaluate Nutrition Information Online?
With the abundance of nutrition content online, it is essential to develop skills to evaluate the reliability of sources. Look for articles and advice that reference scientific studies, are written or reviewed by qualified health professionals, and are published by reputable organizations or institutions. Be wary of sensational headlines, anecdotal evidence, or advice that promises quick fixes or miracle results. Reliable nutrition information is usually balanced, acknowledges limitations, and avoids extreme positions.
When in doubt, consult official resources such as government health agencies, registered dietitians, or peer-reviewed journals. Remember that nutrition science evolves, and recommendations may change as new evidence emerges. Staying informed and open-minded is key to making the best choices for your health.
Popular Food Myths Debunked
Many myths persist despite scientific evidence to the contrary. For example, some believe that eating after 8 p.m. causes weight gain, but research shows that total calorie intake and activity level matter more than meal timing. Another common myth is that detox diets or cleanses are necessary to eliminate toxins from the body. In reality, the liver and kidneys naturally detoxify the body, and there is no scientific proof that special diets or juices speed up this process.
Similarly, the idea that natural or organic foods are always healthier is misleading. While these foods can be part of a healthy diet, the terms "natural" and "organic" do not guarantee better nutrition or safety. It is more important to focus on overall dietary patterns, food variety, and moderation than to rely on labels or trends.
