When we think about nutrition, we often focus on calories, macronutrients, and micronutrients. However, another important factor that can impact our health and well-being is pH level.
pH is a measure of acidity in a substance, and it plays a critical role in our ability to digest and assimilate nutrients from the foods we eat.
What is pH?
First, let’s define pH. pH is a scale that measures the acidity or alkalinity of a substance. The scale ranges from 0 to 14, with a pH of 7 considered neutral. Anything below 7 is considered acidic, while anything above 7 is alkaline.
The human body has a slightly alkaline pH, with a range of 7.35-7.45.
Why is pH important in nutrition?
pH plays a critical role in our digestive process. Each enzyme in our digestive system operates at a specific pH range. For example, stomach acid has a pH between 1.5-3.5, which is highly acidic.
This acidity is necessary to break down proteins in the food we eat. If the stomach acid isn’t acidic enough, proteins won’t break down properly, leading to digestive issues and nutrient deficiencies.
Similarly, the small intestine has a pH range of 7-8.5, which is alkaline. This alkalinity helps neutralize stomach acid and creates an optimal environment for digestive enzymes to work.

If the pH in the small intestine is too low or too high, it can impact the absorption of nutrients.
The Impact of Acidic Foods
Many foods we eat are acidic, such as meat, dairy, and processed foods. While these foods can be part of a healthy diet, too much of them can create an imbalance in pH levels.
When our body’s pH becomes too acidic, we may experience symptoms such as fatigue, headaches, and muscle weakness. Additionally, high levels of acidity can lead to inflammation and may increase the risk of chronic diseases, such as osteoporosis and kidney stones.
How to Maintain a Healthy pH Balance
While some level of acidity is necessary for our body to function, it’s important to maintain a healthy pH balance. Here are some tips for doing so:.
- Eat a diet rich in fruits and vegetables, which are alkaline-forming and help balance out acidic foods.
- Avoid highly processed foods and limit meat and dairy consumption.
- Drink plenty of water to help flush out excess acidity.
- Consider adding alkaline supplements, such as pH drops or greens powders.
The Bottom Line
pH is an essential aspect of our nutrition and overall health. By understanding the role of pH in our digestive system, we can make informed choices about the foods we eat and how they impact our body’s pH balance.
By maintaining a healthy pH balance, we can support optimal nutrient absorption and reduce the risk of chronic diseases.
