A ppt on Acidity in the humans and its adverse effects, foods to chose and to avoid and life style changes to keep healthy !

1. A common pH definition is: "a logarithmic scale, from 1 to 14, used to describe the acidity or alkalinity of a solution". Blood
in the human body should be close to 7.4 on the pH scale. A pH level of less than 7 indicates an acidic solution while a pH
greater than 7 indicates an alkaline solution. 7 is the pH level of distilled water. PH stands for "potential hydrogen". If your
body is too acidic you do not have enough oxygen available for your body cells to stay healthy. When our body is getting
enough minerals from our diet to stay alkaline, our blood can function normally - delivering oxygen to the cells throughout
our body, and carrying away acidic waste to be disposed.But if we struggle to keep our blood at pH level 7.4 it cannot pick up
all of the acidic waste, and fat cells are formed to store the acidic waste instead.
Human pH Balance
Human body pH balance is key. Failure to maintain an alkaline pH in our tissues and cells will hurt our cellular health. Too
much acidity (too little alkalinity) can cause weight gain. Cancer cells, disease-causing bacteria, fungus, viruses and
parasites can thrive in acidic body tissue. A combination of a good alkaline diet, the water you drink, the air you breathe, the
amount of sunlight you are exposed to, how well you sleep, the amount of stress in your life, and how often you get physical
exercise, can have a profound effect on the pH level of your body. This will affect how healthy you are and how long you will
live.

2. D i e t a n d Yo u r I d e a l p H
How can you can you improve your pH levels? Diet changes are the key. Many foods
are too acidic, contributing to a low pH level and poor overall health. Examples include
packaged and processed foods, soda, and most meats. The modern diet of most
individuals is devoted to these types of foods, resulting in the decreases seen in overall
health.
Alkaline foods are important to raise pH back to the ideal level and maintain it. These
include fresh fruits and vegetables, nuts, and increasingly popular “green drinks” that
consist of ingredients including vegetable and wheat grass juices. Drinking lots of
slightly alkaline water will also help to buffer against acidic foods and raise pH.
