The blood’s normal pH range is 7.35 to 7.45, which is slightly alkaline.
When blood pH dips below 7.35, a state called acidosis emerges, rendering the blood overly acidic.
Scientists have long known that tumors have many pockets of high acidity, usually found deep within the tumor where little oxygen is available
Minerals associated with acid-forming foods
- Phosphorus (phosphate, PO₄³⁻) – abundant in meat, cheese, processed foods, and cola drinks.
- Chloride (Cl⁻) – found in table salt (sodium chloride) and many processed foods.
- Sulfur (from the sulfur-containing amino acids methionine and cysteine in protein-rich foods) – metabolised to sulfate, contributing to acid production. This isn’t a mineral ion in food itself but is an important acid-forming component.
Alkalising foods tend to be rich in:
- Potassium (K⁺)
- Magnesium (Mg²⁺)
- Calcium (Ca²⁺)
- Sometimes sodium (Na⁺)
Highly Alkalising foods
- Grasses (Chlorophyll (rich in magnesium)
- Cucumber (High potassium (~150 mg per 100 g)
- Kale (High potassium, High calcium and High magnesium)
- Kelp
- Spinach
- Parsley
- Broccoli
- Sprouts
- Sea Vegetables.

To be aware of:
Although growing evidence from both in vivo and in vitro studies indicates that the reversed pH gradient in cancer cells may represent a promising therapeutic target, current mainstream treatments for advanced cancer continue to rely primarily on chemotherapy and molecularly targeted therapies, with relatively few clinical approaches specifically focused on regulating cancer cell pH.
There are two main therapeutic approaches that target the acidic pH of the tumour micro environment. One is buffer therapy, in which alkalizing agents are administered to neutralize protons, and the other is the inhibition of proton efflux transporters expressed on the cancer cell membrane
