Your Alkaline Foods Guide
An alkaline diet has been touted as a way to reduce the acid load of your diet, boost the body’s energy levels and improve health. But it is important to remember that the pH of your body is tightly regulated by your kidneys and there is very little evidence to show that dietary choices will affect your body’s ph.1
As well as this, different parts of your body have a different natural pH in order to function properly. For example, your stomach has a pH between 1.35 and 3.5 and your skin has a pH between 4 and 6.5. 1 No amount of spinach in your diet is likely to change this. That being said, increasing the number of fruits and vegetables in your diet is associated with a number of health benefits. 2
Here’s a list of alkaline foods and all of their benefits and micronutrient content...
1. Spinach
This leafy green is a great source of vitamin K, which important for the health of your bones. Spinach is also a good source of iron with 100g providing 1.9mg of your recommended iron intake (9mg for men and 14.5mg for women aged between 19 and 50).
And on top of all of this, spinach is also a good source of vitamin C which is a powerful antioxidant helping to maintain immune function and healthy skin. Definitely one to add to your shopping list.

Benefits of alkaline foods
Whilst there is currently limited evidence to show that dietary choices will change the pH of your body (this is tightly regulated by your kidneys), increasing the number of alkaline foods such as the vegetables and fruits listed above may help improve your overall health.
Eating a wide range of fruits and vegetables will ensure you are consuming a wide range of micronutrients and an appropriate amount of dietary fibre.
Take Home Message
The evidence is currently limited to show that consuming alkaline foods will change the pH of your body. Your body’s pH varies across the body and it is tightly regulated by your kidneys.
However, increasing the number of plant-based foods in your diet is associated with a number of increased health benefits and increasing your fruit and veg consumption will increase the nutrient diversity of your diet and improve your fibre intake.
