Spanish newspaper "Digital Daily" recently published an article listing 8 major misconceptions about diet.
Misconception 1: Certain foods can burn fat. "Negative calorie effect" foods are those that require more energy to chew and digest than they contain. Cucumbers, celery, and grapefruit are all said to be the best "negative calorie" foods. In reality, the calories burned are negligible. Low-calorie, nutrient-dense foods are what truly help with weight loss.
Misconception 2: Eating smaller, more frequent meals is healthier than three meals a day. In fact, as long as the food choices are healthy and low in calories, any eating pattern can be beneficial for health. The key is to control daily calorie intake.
Misconception 3: Fresh fruits and vegetables are more nutritious than frozen ones. In fact, nutrients can also be obtained from some frozen fruits and vegetables, and the same goes for canned vegetables. However, food manufacturers often add salt, sugar, and fat to otherwise healthy products, so consumers must read labels carefully when purchasing.
Misconception 4: Decaffeinated coffee contains no caffeine. Studies have confirmed that different types of decaffeinated coffee contain at least 8 to 32 milligrams of caffeine. Although this is much less than regular coffee, it can still have an effect on the body.
Misconception 5: Margarine is healthier than butter. Butter contains saturated fatty acids, and excessive consumption can raise "bad" cholesterol (LDL), thereby increasing the risk of heart disease. Therefore, some people use margarine as a substitute for natural butter. However, margarine contains trans fats, so it's best to choose trans fat-free vegetable-based margarine.
Misconception 6: Eating bananas will make you gain weight. A medium-sized banana contains about 105 calories; you would need to eat six of them to match the calories in one pizza. Bananas provide a large amount of fiber, magnesium, and potassium, which help control blood pressure. Bananas are also a source of Vitamin B6, which helps boost the immune system. It is recommended to chop bananas, mix them with grains and yogurt, and chill them for a dessert.
Misconception 7: Cravings are a signal from the body that it's lacking a certain nutrient. For people who crave food, this is the most persuasive excuse, but it's not true. Scientists have conducted numerous studies to prove this wrong.
Misconception 8: Cooking vegetables destroys vitamins. In fact, processing vegetables can enhance the body's ability to absorb some of their nutrients. For example, lycopene, which can help prevent certain cancers, is more abundant in cooked tomatoes than in raw ones. The most important thing is not to cook them for too long. Steaming, grilling, or using a microwave is best, and avoid adding too much water.
