It balances pH--Lemon is an acidic food, but once metabolized, it becomes alkaline. Why bother? To put it most simply, alkalines help keep the oxygen in your blood at a safe pH level, and this helps your body heal itself (less yucky medicine), assimilate nutrients and fight off unwanted sickness.
It keeps skin clear and glowing! Its helps to hydrate and moisturize your skin from the inside out. It also contains A TON of Vitamin C, which helps with wrinkles and blemishes. ((Yay for that!!))
It kick starts the digestive system--a big glass of lemon water is a great way to start the morning! It increases urination which helps purify it. It also helps with heartburn and constipation. lol It has a strong cleansing effect and helps eliminate those bad toxins!
It helps with weight loss--Did you know that keeping your body in an alkaline state can help people lose weight faster? It really give your metabolism a nice kick start to the day!!! They also help keep one full, longer....much like drinking a glass of water, put they pack a bit more punch. They also have a diuretic effect, which helps with water weight gain.
It helps kick the soda habit--I have found that adding lemon to sparkling water and adding a whole lot of ice satisfies any sugary drink craving I might have. I gave up cokes over 2 years ago and I really don't miss it AT ALL. I don't think I could stand the sweetness of it now.
Try to drink it through a straw to keep the lemon off your teeth so the acid doesn't wear on your tooth enamel.
