Myths are everywhere when it comes to fitness. It can be dangerous if you don’t do your research. Knowing what exercises to do, what protein powders to buy, how much sleep you should get. Knowing all of the facts is essential and the firs step to making progress.
High Protein is Harmful to Your Kidneys
In 1983, researchers discovered that an increase in protein increased the glomerular filtration rate as well. GFR is basically the amount of blood your kidneys filtrated per minute. They assumed that higher GFR will put your kidneys under higher stress. However, this assumption was wrong, higher GFR does not negatively affect kidney function. There is zero published record showing that increasing protein in your diet will have a negative effect on your kidneys.
Sweet Potatoes Are Better Than Others
Because of the highly processed version of white potatoes and how they are consumed (in fries, covered in sour cream, as chips, etc.) sweet potatoes are seen as better. Neither are necessarily better than one another. Sweet potatoes are good for fiber and vitamin A. While white are great for iron and potassium.
Salt Causes High Blood Pressure
In 1940, Duke University researcher by the name of Walter Kempner treated patients with high blood pressure by reducing their salt intake. Later this became widely known. The problem is that yes, consuming a large amount of salt will give you higher blood pressure, but only because it is not balanced with the level of potassium in your diet. Low potassium intake has as big of an effect on blood pressure as salt. You can get more potassium by eating vegetables, a wide variety of fruits, and legumes.
High Fructose Corn Syrup is More Fattening Than Regular Sugar
This one should be obvious. Both sugars cause weight gain when consumed in excess. Sucrose is almost chemically identical to high fructose corn syrup, but both can be very harmful to your body when you eat too much. Everything in moderation.
