Alkaline Food Scanner: Check Any Food in a Second

Point your phone at a food and find out whether it's alkaline — and whether it's on Dr. Sebi's approved list. That's the whole idea. The scanner is part of the Ackaline app, free to start, on iPhone and Android.

How it works

Camera. Open the scanner, point it at the food, and it identifies what it's looking at and gives you the answer.

A photo you already have. Pick an image from your gallery instead — the shelf you photographed in the shop, last night's dinner, a page of a menu.

Typed search. When there's nothing to point at, or the camera can't place an unusual variety, type the name and get the same answer.

All three routes return the same card, and it isn't just a yes or a no. It explains the food: where it sits on the list, what its pH is, and why it lands where it does.

What comes back

  • Whether the food is alkaline
  • Whether it's on Dr. Sebi's approved list
  • A pH rating
  • The benefits on record for it, in plain language
  • An overall rating from Excellent down to Poor
  • One line on why it lands where it does

Why it's worth checking rather than guessing

Two things make this harder than it sounds, and they're worth understanding whether or not you use the app.

The list is closed. On the guide, a food is approved because it is named, not because it belongs to a category. So there is no rule you can reason from. Spinach, garlic, carrots and sweet potato are all off the list despite being staples of most healthy diets. Shiitake is the one mushroom that isn't on it. Even bananas are narrower than people expect — the guide lists burro and mini burro, not the common Cavendish. Checking the name is quicker than reasoning about it.

A food's pH and its effect on the body are different numbers. Honey measures pH 3.9, about as acidic as orange juice, and is mildly alkaline-forming once digested. Brown rice is near-neutral in the bowl and strongly acid-forming after. Lemons are acidic and alkaline-forming. So "does it taste acidic?" tells you almost nothing. Honey is the clearest example of the gap.

What it won't tell you

It won't tell you that a food will cure, treat or prevent anything. This is food, not medicine — if you have symptoms or a diagnosis, that belongs with your doctor, and eating well sits alongside medical care rather than instead of it.

A food that isn't on the list comes back as not approved, not as dangerous. And where reproductions of the guide differ on a food, the card says so rather than picking one for you.

Using it well

Scan the unfamiliar, not the obvious. Most of what you eat in a week is a handful of foods you'll learn in the first fortnight. The scans are worth saving for the things that genuinely stop you in the aisle — an unusual green, a variety of tomato, a grain you haven't met.

Photograph the shelf. If you're in a hurry, take the picture and check it later from your gallery. Deciding at home is easier than deciding in a shop.

Type for anything packaged. Typed search handles prepared and packaged foods better than the camera does, and it's also how to check the things that hide in a label — yeast, vinegar and added sugar in particular.

Common questions

Does the scanner need internet?

Yes. Recognising the food runs on our servers, not on your phone, so a scan needs a connection. The rest of the app — the food list, your plan, the fasting timer — doesn't.

Does it scan barcodes?

No. A barcode identifies a package. This looks at the food itself and tells you where it sits on Dr. Sebi's list, which is a different question — and most of what's on the list is loose produce with no barcode on it at all.

What if it can't identify the food?

Type the name. Typed search covers what the camera can't place, including packaged and prepared foods.

How many scans do I get?

10 a month on the free tier, 50 on the paid one. Reading the food list and logging meals aren't counted against it.

Is it accurate?

It reflects the approved list as published in Dr. Sebi's nutritional guide. Lists vary slightly between reproductions, and we note where they do. The individual food pages on this site go into each one in more detail.
