5 Nutritional Myths They Want You To Believe
Negative calorie food…?
Have you ever heard of “negative-calorie food”? It means the food requires more energy from your body to digest than the calorie the food provides, resulting in weight loss. People like to use celeries or apples as the example.
This is NOT true. (Sad, I know.)
Proteins have the highest thermic effect (20 to 30%), which means it requires more energy to digest protein than the food that has 10%. But there are still plenty of calories left over in your body after you ingest proteins.
The only negative-calorie food would be cold water. Water contains 0 calories, and it requires your body to warm up the cold water when you drink it. However, your body only burns 100 calories if you drink ONE LITRE of cold water. I mean, drinking water is good, but probably not the greatest method to rely on if you want to lose weight.
However, foods that are low in calories may help with weight loss because you can fill with your stomach with fewer calories. Imagine that your stomach needs 1000ml of something to feel full; the calories of 1000ml of pizza are a lot higher than the calories of 1000ml of carrots!
Diet soda help you lose weight…?
I have no clue why some people say this.
Diet soda is made with sweetener instead of sugar, therefore the calories in diet soda are less than the regular ones. For instance, If you normally drink 1 litre of coke a day, and now you decide to change to 1 litre of water, or coke zero, it may help you lose weight, because you cut down the calories you take in; but if you order yourself a large pizza, 2 burgers, 8 chicken wings and a bottle of diet soda, the soda won’t magically make all the calories from those food disappear.
P.S water is the best.
Food that help you lose fat in certain body parts…?
You may find LOTS of posts on the internet that tell you food X helps you lose your belly, or that Y food gives you a thigh gap. The thing is, everyone’s body is different, and your body has no control over where the fat is going to grow or lose. This means, when you gain weight, or when you lose weight, it’s up to your body to decide where it’s going to be.
One thing that may help you to look thinner on a certain body part is exercise. You can do workouts that target a certain body part, when you’re toned up you will look one (or more) size smaller!
Detox diet is the best…?
Or cleanse diet. The diet claims to “detox” your body, get rid of harmful substances, boost your immune system and give your organs a break.
However, there is no scientific evidence that any of these so-called cleanses really benefit a person’s health. Our organs, especially liver and kidneys, together with immune system, can handle detoxification in your body. As long as you don’t drink the excessive amount of alcohol or over-dose on some medications, your body, if healthy, can detox those little toxins on its own. (Let me skip all the physiology of liver.)
Dietitian Katherine pointed out: “So why do so many people claim to feel better after detoxification? It may be due in part to the fact that a detox diet eliminates highly processed foods that have solid fats and added sugar. Simply avoiding these high-calorie low-nutrition foods for a few days may be part of why people feel better.”
The best detox is an overall healthful eating, which includes plenty of fresh fruits and vegetables, whole grain, less processed food and refined sugar, limit intake of alcohol and avoidance of nicotine.
Fresh veggies are better than frozen veggies…?
Ok, I know I have been saying “fresh vegetables” everywhere in my posts, but what about frozen vegetables? I have had people debating with me that frozen vegetables are bad.
Most of the fresh vegetables you get from the markets have to go through a long transportation to get to where they are. Besides, we seldom finish the vegetables we buy within 1 to 2 days, the longer they are exposed to the air after being picked, the more nutrients they lose. By the time you consume them, they may not have the same nutritional value as the frozen vegetables, which the fast freezing process helps to slow down nutrient loss. Of course, if you have a vegetable garden, those vegetables would be the best!
