Banana Skin Peel WhitenTeeth

Saw this amazing fact of banana peels on a facebook page. I've check about many benefts of banana skin but this is the 1st time I heard banana peel can whiten teeth. Can it really do so?

Next time you want to throw banana skin away, think twice. See below story.

Take a piece of the inside of the banana peel and gently rub around on your teeth for about 2 minutes. 

The amazing minerals in the peel like potassium, magnesium and manganese absorb into your teeth and whiten them. 

Other health benefits of banana peel

Banana peels are also rich sources of potassium and contain much more soluble and insoluble fiber than their flesh. Dietary fiber promotes digestion and bowel movements and can reduce blood cholesterol levels. Banana peels also contain tryptophan, which increases serotonin levels in the body and affects mood, much like the drug Prozac does. According to "Prescription for Nutritional Healing," researchers in Taiwan discovered banana peel extract can ease depression because of its effect on serotonin, which is a neurotransmitter in the brain responsible for balancing mood and emotions. Others found that eating two banana skins a day for three days increased blood serotonin levels by 16 percent. Further, banana skin contains lutein, a powerful antioxidant that protects the eye from free radicals and harmful frequencies of UV radiation from the sun. Lutein has been proven to reduce the risks of cataracts and macular degeneration, as cited in "Biochemical, Physiological and Molecular Aspects of Human Nutrition."

用香蕉皮美白牙齒既健康又安全，因為香蕉皮是礦物質和維生素的豐富來源。它不像其它天然美白劑一樣具有腐蝕性，並且價格也非常便宜。

可以首先使用香蕉皮，然後用一種天然牙膏刷牙。最好是用熟透的香蕉，因為它的鉀含量最高。

用一片香蕉皮內側輕輕摩擦牙齒2分鐘。香蕉皮包含的鉀，鎂和錳等礦物質能被牙齒吸收並發揮美白作用。可以在睡覺前和起床後重複這一步驟。每天用香蕉皮摩擦牙齒兩次，很快就能看出明顯效果。

沒有必要把舊香蕉皮扔掉，可以回收利用它。它的豐富礦物質成分對植物很有好處，可以當做肥料施用在土壤中，植物喜歡它。此外，沒有用過的香蕉皮可以切開放進冰箱保存，以便於下一次使用
