Recently, people are of the habit of eating food just for sustenance. Sometimes, the so-called good food turns out to be harmful to the body. But that's a story for another day. What I'm concerned about is how our system could be in a good state at all times irrespective of what we eat. Apart from the whole hospital procedures and processes, you can purify your system at home in a much simpler way.
I'll give you just few tips on how this works
First, taking a glass of water immediately after waking up every morning helps in flushing your system and washing down all the toxic that your body do not need. If you make this a habit, in no distant time you will discover that all the early morning sicknesses and ailing such as sneezing and coughing will vanish.
The second one is the intake of cucumber every morning. Cucumber contains very active cleansing supplement. All you need to do is to take it in the morning long before breakfast and you're good to go.
Thirdly, you can also use watermelon. The consumption of fruits and veggies such as watermelon helps in cleaning up your body (system) and leaving you with that fresh feeling. All these works better if you take them early in the morning.
Also, forming a habit of drinking warm water is very important and helpful. Do you know that most oily foods and fries that we eat slows down digestion and causes constipation. This sometimes constitute what I term "dirty system". If you drink warm water frequently and regularly, it will help dissolve all the unwanted oil in your belly and leaving your system refreshed.
Well-said
