Short answer: mango is genuinely acidic as a food and alkaline-forming in the body, and it is approved. It is one of the cleanest illustrations of why those two things are different measurements.
The numbers
Mango measures pH 3.40 to 4.80 depending on ripeness and variety. That is properly acidic — below the 4.6 line food scientists use to separate high-acid from low-acid foods. Under-ripe mango sits at the lower end.
Its PRAL is −3.3: alkaline-forming, and more so than cucumber or watermelon.
Is mango Dr. Sebi approved?
Yes. Mango appears on every reproduction of the approved fruit list.
Why the two numbers disagree
A food’s pH is a direct reading of what is in your hand. PRAL estimates what is left for your kidneys to deal with after digestion, calculated from protein, phosphorus, potassium, magnesium and calcium.
Stomach acid sits around pH 1.5 to 3.5, more acidic than almost any food. Whether something arrives at pH 3.4 or 6.4 makes very little difference by the time it is through. What persists is the mineral content — and mango is potassium-rich.
Honey is the most extreme version of this gap, at pH 3.9 and still alkaline-forming.
How to use it
Mango is one of the few fruits where variety changes the experience completely, and knowing the names is worth more than any other tip on this page. Alphonso and Kesar, in season from roughly April to June, are dense and almost custard-like with very little fibre. Ataulfo or honey mangoes are the small flat yellow ones, sweet and smooth, and they are available for much of the year. Julie and East Indian are the Caribbean favourites, rich and slightly resinous. Tommy Atkins is the big red-and-green one that dominates supermarkets; it travels well and looks handsome but it is fibrous and comparatively bland, so if that is all you can find, buy it under-ripe and use it in a salad rather than expecting much eaten out of hand.
Judge ripeness by smell and give rather than by colour, which varies by variety and tells you nothing on its own. A ripe mango smells sweet and faintly resinous at the stem end and yields to gentle pressure the way a ripe avocado does. Ripen firm fruit on the counter in a paper bag, which traps the ethylene and takes a couple of days off the wait. Once ripe, refrigerate and eat within about five days; never refrigerate an unripe one, because the cold stalls ripening for good and leaves the flesh mealy.
To cut one, stand it on its end and slice down either side of the flat stone to get two cheeks, score each cheek in a grid without cutting the skin, then push the skin inside out and the cubes stand up ready to cut off. The flesh clinging to the stone is the cook’s share.
A normal portion is about half a large mango, or a cup of cubes. Beyond eating it fresh, cubes freeze extremely well and blend into a thick smoothie with no ice needed. Under-ripe green mango, shredded with a squeeze of key lime, chopped onion and a pinch of pure sea salt, makes a sharp crunchy salad that is a staple across South Asia and the Caribbean. Ripe mango blended with a little lime and water makes a simple juice, and mango with avocado is a better pairing than it sounds — the fat rounds out the acidity.
This is food, not a treatment for any condition. If you have symptoms or a diagnosis, see your doctor — eating well sits alongside medical care, not instead of it.
Common questions
Is mango too acidic for reflux?
Acidic foods can trigger symptoms in some people, though trigger foods are individual. The acidity of the fruit is the relevant number here, not the PRAL.
Are all mango varieties approved?
The guide names mango without restricting the variety.
Does ripeness change it?
Ripe mango is less acidic than under-ripe. The PRAL direction does not change.
