Almost everything we hear about our health comes from trusted sources such as friends or family, social media, and the success of “Wellness” campaigns. Some of the information we receive may be helpful, but much of what we hear comes from myths. Following the myths creates an environment where people are fearful, make poor lifestyle decisions, and ultimately injure themselves. In this article, we will examine some of the most prevalent health myths and how science refutes them.
Myth 1: The More Water You Drink, The Better For Your Health.
Common Belief: More water = better health.
Scientific Findings: Hydration is essential; however, excessive water intake can dilute electrolytes. In extreme cases, water intoxication (hyponatremia) may occur. Water needs vary between individuals due to many factors, including temperature, activity level, diet, and current health status. Therefore, the scientific consensus is to drink only when thirsty and maintain a pale yellow color in urine.
Summary: You should drink just as much as you need; Do not force it.
Myth 2: Skipping Meals Leads To Better Weight Loss.
Common Belief: Skipping meals (Especially breakfast) will lead to faster weight loss.
Scientific Finding: It is well documented through many research studies that skipping any meal results in crashes in blood sugar, results in larger meals later, decreases metabolic rate, and decreases hormone production. When you eat consistently over time, your body regulates hormones responsible for hunger (ie, Ghrelin and Leptin), resulting in better long-term results in controlling body weight.
Summary: Eat regularly and eat nutritional foods.
Myth 3: Carbs are not harmful to health
Common Belief: Carbohydrates lead to weight gain and should be eliminated from your diet.
Scientific Findings: The human body uses carbohydrates as its main source of fuel; therefore, whole grain and unrefined carbohydrates (vegetables, legumes, whole grains, fruits) are the fundamental building blocks required to maintain a healthy gut, support cognitive function, and sustain energy levels throughout the day. The actual issue with carbohydrates is excessive sugar intake and refined (or processed) carbohydrates.
Summary: It is more important how much and what you eat rather than trying to eliminate carbs from your diet.
Myth 4: Natural/Herbal Products Are Safe
Common Belief: If it’s natural, it can’t harm you.
Scientific Findings: Many natural substances may interact with prescription drugs, influence hormone levels, or create an allergic reaction. In particular, the amount of a specific herb you take may hurt your kidneys or liver, depending on how much you consume. Remember that ‘natural’ does not eliminate the need for scientific evaluations or for individuals to use the proper dosages of natural remedies.
Summary: Natural does not always equal no risk.
Myth 5: More Sweat Equals More Fat Loss
Common Belief: The more you sweat, the more fat you will lose.
Scientific Findings: Sweating is your body’s way to cool itself; it is not a metric for calorie expenditure. The loss of fat will depend on both energy expended by the body as well as metabolic activity, rather than just on the volume of sweat produced. The weight lost due to sweating is mainly excess water.
Summary: Losing fat comes from being consistent, not sweating.
Myth 6: Getting sick with a cold/flu is due to being cold
Common Belief: When the weather is cold (or “chilly”), it will make you sick.
Scientific Findings: A cold or flu is actually caused by a virus, not from being exposed to cold weather. Being in a cold climate could lower your immune response, but also being in a crowded space during the colder months could increase your chances of contracting the virus.
Summary: It’s viruses—not the temperature—that cause sickness.
Myth 7: “Detox” diets remove toxins from your body
Common Belief: Juices and detox teas remove toxins from the body.
Scientific Findings: The liver, kidneys, lungs, and intestines perform this function naturally, unless there is some sort of problem with these organs. There are very few studies that support the effectiveness of detox products. Following an extreme detox regimen can lead to fatigue and nutrient deficiency.
Summary: Your body already has an effective, natural detoxification system; no special diet is required.
Myth 8: Cracking your knuckles will result in arthritis
Common Belief: By cracking your knuckles, you will develop joint problems.
Scientific Findings: There are no studies that show a direct correlation between arthritis and cracking knuckles, and it is believed that the noise heard from cracking your knuckles is caused by gas bubbles in the joint fluid popping. However, continual knuckle cracking may cause temporary irritation to the joints or a decrease in grip strength.
Summary: Cracking your knuckles may annoy others, but it is not linked to arthritis.
Myth 9: You must take supplements to achieve optimal health
Common Belief: Supplements are important for everyone to consume.
Scientific Findings: You mostly absorb nutrients through food; however, supplements may be beneficial for some specific deficiencies (i.e., vitamin D or iron) but can also lead to toxicity or imbalances when taken too frequently.
Summary: Before starting a supplement, ensure that you have a nutrient-rich diet and only add supplements when necessary for a deficiency.
Myth 10: Mental health conditions are a “figment of your imagination.”
Common Belief: If you are experiencing stress, anxiety, or depression, you have a weakness.
Scientific Findings: Mental health disorders arise from factors related to the brain, behavioral health, hormones, family genetics, and environmental stressors. These illnesses require understanding, treatment, and support.
Summary: Mental health is as legitimate as physical health.
