Should you try one of the trendy liquid "cleanse" or detox diets to get rid of "toxins" within your body?
This is marketing madness! There is NO evidence whatsoever that any of these diets are beneficial for your digestive system. In fact, they may actually be harmful in that the good bacteria within your colon is removed along with the bad bacteria. The good bacteria is needed to maintain a healthy digestive tract. The reality is that your body is designed to rid itself of foreign bacteria all on its own--it does NOT need help in this regard. Your kidneys, liver, lungs as well as your colon are the filtering organs of your body and they work fine on their own without help. No need to fast or purge yourself to rid your gut of bad bacteria. By the way, any weight that's lost from fasting within one to two days is mostly due to water loss, not fat loss. Prolonged fasting is not healthy because of the risk of malnutrition.
Eating egg whites and throwing out the egg yolks is a big mistake! To wit: egg yolks contain vitamins A, B2 (riboflavin), B5, B6, B9 (folic acid), B12, and vitamin D in addition to minerals such as selenium, phosphorus, iron, and zinc. Egg yolks are an excellent source of protein (8g each), omega-3 fats and antioxidants such as lutein, zeaxanthin and carotenoids.
Cholesterol should not be thought of as a health concern when eating whole eggs. Why? Because food cholesterol is NOT the same as blood cholesterol. That is, getting more cholesterol from food does NOT necessarily cause higher cholesterol levels within your body. It is a myth perpetuated by the media that cholesterol is the enemy. For one thing, increased blood cholesterol is associated with higher testosterone levels within the blood--that's a good thing! In addition, the media has continued to propagate the myth for several decades that high-saturated fatty diets and cholesterol are the root cause of heart disease and obesity. The irony is that since the eighties, the rate of obesity and Type-2 diabetes in this country has actually increased from eating low-fat, low-cholesterol foods. The real culprit is excessive consumption of refined carbohydrates (sugars)--not fats.
BOTTOM LINE: Egg yolks are a healthy source of vitamins, minerals and antioxidants. Egg yolks are also a valuable source of protein to maintain strong bones and muscle tissue. The only caveat is to eat the yolks in moderation--two to three daily is okay. Athletes and bodybuilders alike are ahead of the general public on this issue--eating whole eggs is the way to go to stay strong and healthy!
High protein intake is harmful to your kidneys.
There is no conclusive evidence that this is the case. The usual recommendation is to eat your target body weight in grams of protein daily. For example, if you're 180-lbs but want to be 200-lbs, eat 200 grams of protein daily.
Sweet potatoes are better for you than white potatoes.
The reality is that both types of potatoes have complimentary nutritional differences but one is not necessarily better than the other. For instance, sweet potatoes have more fiber and vitamin A, but white potatoes are higher in iron, magnesium and potassium.
Red meat causes cancer.
No study has shown a direct cause-and-effect relationship between red-meat consumption and cancer. How the meat is cooked is really what is at issue here: overcooking meat under high heat tends to increase the release of carcinogenic compounds which increases cancer risk.
High-fructose corn syrup (HFCS) is more fattening than regular sugar.
Both HFCS and sucrose, or table sugar, contain comparable amounts of fructose. At issue here is not necessarily HFCS but fructose in general. Consuming either HFCS or sucrose will cause weight gain, in the form of fat, when consumed in excess.
Salt causes high blood pressure and should be avoided.
If you have a healthy blood pressure of less than 120/80, there is no need to restrict salt intake. On the other hand, if your blood pressure exceeds the aforementioned amount, it may be wise to cut down on your salt intake and increase your potassium intake. The reality here is not so much how much salt or potassium you eat, but rather the balance between the two minerals that matters most. Hence, if you eat a high-salt diet but very little in the way of potassium, then you should lessen the imbalance between the two minerals by either eating less salt or taking in more potassium. Good potassium sources include spinach, broccoli, bananas, white potatoes, and beans.
