whether you're reading from a popular website or receiving a plausible email from a friend, be skeptical. Many myths about nutrition and health start from a single source, but once they spread, they are treated as facts. Here, we expose seven myths on the Internet. Do you know any other myths? Please share them in the comments section below.
Credit: let me check. Myth: it takes 21 days to break a bad habit (or form a new one). Many popular self-help masters claim that it takes 21 days to break or form a bad habit. But the truth is that there is no magic time frame to make lasting changes. Some people can develop a new habit (such as eating more vegetables) in a few days. Others may take weeks or months. A study published in the European Journal of psychology found that it takes an average of 66 days to develop a new habit, such as eating a piece of fruit every day. However, great changes have taken place. The author finds that adaptation time is a function of specific habits and individuals. If you're trying something new, like daily exercise, give yourself time to make it a habit. It can't happen overnight or in 21 days! correlation: research: how habits are formed correlation: 17 reasons why you may need more omega-3 fallacy: muscle can become fat (and vice versa) muscle and fat tissue are completely different, they cannot transform each other. " It's like saying lead can turn into gold, "said Ed ingbresson, a certified personal trainer at the American College of sports medicine. When you stop exercising, what really happens is that your muscle mass drops. How to gain weight is by consuming more calories than by consuming, which is much easier when you lose highly metabolic muscle tissue that helps keep your body running like a V8 engine. Bottom line: stay active. If you stop exercising, be sure to eat less to avoid weight gain. correlation: comparison between the statement of muscle turning into fat and the fact Credit: Getty Images related: should you try juice cleaning?

Some studies have shown that omega-3 fatty acids, commonly found in fatty fish like salmon, as well as walnuts and flaxseed, may help relieve joint pain. Omega-3 fat doesn't actually lubricate our joints the way you grease squeaky doors. In contrast, omega-3 is believed to reduce inflammation and pain. A recent review of multiple studies on fish oil and joint pain found that participants taking fish oil supplements reported reduced morning stiffness, joint swelling and pain, and reduced demand for anti-inflammatory drugs to control their symptoms.
4. Myth: canola oil is made from rapeseed (poisonous!) Many people think that rapeseed oil comes from rapeseed plants, but actually it comes from the pressed seeds of rapeseed plants. Although canola oil does contain very high levels of erucic acid, a large amount of compound that is toxic to humans, canola oil contains very low levels of erucic acid. The false information about canola oil may come from the fact that canola oil plants developed in the 1960s by crossing traditional plants with rape to reduce the erucic acid and glucosinolates content in canola oil. Although canola oil is not genetically modified by definition, up to 2010, 90% of canola oil crops were genetically modified to improve their resistance to pesticides. To avoid GM crops, always look for organic and extruded rapeseed oil (mechanically extracted at 120 ° F and chemical temperatures).
5. Myth: from celebrities to personal trainers, "juice cleaning" is the best solution for long-term weight loss, including many people who advocate juice "cleaning". For most healthy people, occasional short-term juice cleaning won't hurt, but you may feel hungry and tired. If you really want to help your body, exercise, sleep and eat a healthy and balanced diet.
6. Myth: some foods, such as celery, have negative calories. When something sounds too good to be true, it's likely to be. "Negative calorie food" may sound great, but unfortunately, there is no such thing. The myth of "negative calories" stems from the fact that some foods burn more calories than they provide. The wrong logic of this urban legend is that the thermal effect (TEF) of food, that is, the energy needed to digest certain foods, can provide some foods with less than zero calories. Celery, apples and limes are the foods touted as low calorie foods. Sadly, there is no negative calorie food. TEF is usually 10% - 20% of the calories in food. Suppose the celery stem has seven calories. Even if we assume 20% TEF, it means you have about 5.5 calories left.
7. Fallacy: fresh agricultural products are always better than frozen agricultural products. But because frozen fruits and vegetables are harvested in an hour, they basically "lock in" their vitamins and minerals, and in many cases, their nutrition is equal to or better than their fresh counterparts. When you consider that freshly harvested agricultural products may take days or even weeks to transport or store before consumption, it makes sense and may lose key nutrients during consumption. A healthy diet can include fresh and frozen produce.
8. Myth: cutting onions contains bacteria that can cause food poisoning. Have you heard this myth before? Many of us don't. According to a viral email, sliced raw onions are a "bacterial magnet" and should not be stored even for a short timePut it in the refrigerator. It's not true. In fact, according to the American onion Association, chopped onions can be refrigerated in sealed containers for up to seven days. The only way onions can be contaminated is if they are mishandled. Always wash your hands when cutting any agricultural products and use clean chopping boards and knives, because this will cross contaminate the food. Is it true that onions absorb bacteria?
What do you think? Have you heard of these myths before? Are you surprised that they were exposed? Are there any other nutrition and health myths we've missed out on that you think we should deal with in an upcoming piece?
