You should be using spring or purified water, fresh lemons (organic if possible). Use half a lemon per a glass of water and drink before eating, drinking, etc. Here are a few health benefits:
Aids In Healthy Digestion
Lemons are high in vitamins/minerals that aid in digestion, making them a natural detoxifier. Drinking lemon water first thing in the morning kickstarts the body’s digestion process. Lemon juice also relieves heartburn and bloating.
Natural Cleanser/Diuretic
Lemon water helps flush out unwanted toxins in your system. The lemon juice stimulates the liver and increases detoxification.
Boosts Immune System
Lemons are high in Vitamin C, potassium and phytonutrients which all aid in enhancing the immune system.
Balances pH Levels
Although lemons are an acidic fruit, they have an alkalizing effect on the body. Disease is prominent in an acidic bodily state, so eating high alkaline foods (such as lemons) helps create pH balance in your body.
Aids In Weight Loss
Lemons contain a high level of pectin fiber, which helps decrease hunger cravings. Warm lemon water is a well known appetite suppressant.
