What is the Most Alkaline Food on Earth?


The alkaline diet is focused around eating alkaline foods and avoiding acid foods. So wouldn’t it make sense to know what the most alkaline food is? Of course, there are many contenders, but if you make sure you eat a lot of the most alkaline food then you will rapidly start to experience the wonderful benefits of the alkaline diet.

How we know that foods are alkaline?

There are two ways to determine whether a food is acid or alkaline. A right way and a wrong way! The reason I say this is because one method tests the alkalinity or acidity of the food before it is eaten whereas the other measures whether the food is acid-forming or alkaline-forming in the body and I am much more interested in the latter.

This is why you see the differences in the acid/alkaline food charts. To quote a previous blog post, here is my explanation:

Some charts determine acidity or alkalinity on the food before it is consumed & others (like mine) are more interested in the effect the food has on the body after it has been consumed.

Personally, I have no interest in what a food is before I’ve eaten it – I want to know whether it will alkalise or acidify my body. Make sense?

Some stand out examples include fruit, as you mentioned, such as banana – but another great example is the low sugar fruits such as tomato and lemon. These are listed under the PRAL charts as acidic, and in their natural state they are – but they are very, very alkalising once consumed and are a really integral part of the alkaline diet – featuring in hundreds and hundreds of recipes.

I hate to think of the amount of people there are out there who are eating a heap of high sugar fruits every day and are not getting any tomato, avocado, lemons, limes etc.

Some people I have spoken to even eat ONLY fruit for half of the day. They are literally living the acid diet!

So, What is the Most Alkaline Food

There are many contenders! Here is a run down of my favourites:


spinach alkaline food

Spinach is a great addition to your diet. It ticks all of the boxes: dark green; leafy; full of chlorophyll and absolutely packed with nutrients including vitamin k; vitamin a; vitamin c; vitamins b1 b2, b3 & b6; vitamin e and contains the following highly alkaline minerals:

  • manganese
  • folate
  • magnesium
  • iron
  • potassium
  • calcium

Plus, for those who are worried that living alkaline will not provide enough protein & calcium – one serve of spinach provides 11% RDI of protein and 25% RDI of calcium. Lovely stuff.

I also like that spinach can be easily used in juices, smoothies, salads, wraps and can also be steamed lightly to let you eat a massive serve really easily. Seriously, try it – steam 3 serves of spinach down, season and you can easily eat it in one meal.


cucumber alkaline food

Cucumber is a very big part of my life! At any given time I’ll have up to 12 cucumbers in my fridge! Brilliant in juices and smoothies they also provide a base for most of my alkaline soups and I love them in salads too. Belonging to the same family as watermelon, zucchini, pumpkin, and other types of squash – they’re water-rich and nutrient dense.

Containing solid levels of vitamin c; vitamin a; potassium; manganese; folate and magnesium they are not as nutrient dense as spinach, but do contain way more water, which has it’s obvious benefits.

Fantastic for the skin, cucumbers are highly alkaline and so important to the alkaline diet. Even if you find the concept of drinking a green vegetable juice too much at this stage, throw a cucumber in with your other juice – you’ll barely notice the taste but you’ll definitely notice the nutrition!


broccoli alkaline food

BROCCOLI! What a star. Containing masses of vitamin c; vitamin k; vitamin a; folate; fibre; manganese; potassium; magnesium; iron and protein – broccoli really packs a nutritional punch. Touted for it’s amazing health benefits, broccoli HAS to be a part of your diet. It’s just too good.

Steamed, raw (in salads) or lightly steam fried, it is a fantastic food. Plus, when it is steamed the fibre in the brocolli binds and is a really effective digestive tract cleanser!

While I am not making this claim directly myself, heaps of recent research has linked broccoli to being very effective against many types of cancer and other degenerative disease.

Here are just a few reports from the dear old BBC:

Broccoli fights cancer
Broccoli fights prostate cancer
Broccoli fights heart disease


kale on chopping board

A wildcard in this list that was originally going to just be the three above, Kale is included because of it’s excellent antioxidant properties, as well as it’s alkaline nutritional profile that includes masses of vitamin K, vitamin A and vitamin C, as well as the important minerals manganese, calcium and iron.

A lot less commonly seen than the other foods on this list, kale is a great addition to your diet. I like to juice it and include it in my legendary dinner “The Vegetable Mountain” (quite simply a mountain of steamed vegetables) as well as finely sliced in steam/stir frys and with my Alkaline Cooked Breakfast.

A word of warning: do try to find organic kale if you can as pesticides are commonly found on kale that is sold in supermarkets. If you have an ionizer, wash the kale in strong alkaline water as this alkaline water removes pesticides very effectively.

So Which Food is the Winner: The Most Alkaline Food

Based upon all factors including nutrient content and ease of use – I would have to go with spinach – spinach is the most alkaline food.

It is SO full of nutrients, highly alkaline minerals and you can use it in so many recipes it means you can get so much of it into your diet – absolutely fantastic!

So eat up and follow popeye’s advice!

    Are siete casava tortillas alkalizing?

  2. janeen Reply

    1. is it the skin of the cucumber that ratchets up its alkalinity? meaning: if i peel the cuke for green smoothies, am i defeating the purpose by stripping away the alkaline source?

    2. re the 80/20 rule and the optimal alkaline/acidic food intake ratio: what is the metric you’re using? is it weight? volume? calories?

    3. if the ph ultimately required by our blood is ph7.365, then are we saying EITHER (a) eat foods that measure 7’s OR (b) balance the highly acidic “0’s” with highly alkaline “14’s”? meaning, if it’s ultimately all about reaching a ph of 7.365, then is there harm in eating ONLY foods that measure 7 (rather than doing the balancing act spanning both 14’s and 0’s)?

  3. Rajesh Reply

    I don’t understand you mean by “Some people I have spoken to even eat ONLY fruit for half of the day. They are literally living the acid diet!”

    How can eating (only) fruit for half a day make you acidic? Can you explain please?

    How much of the cucumber benefit is in the skin that is commonly peeled off?

    • ross Reply

      Hi Bruce

      Lots. If you’re peeling because it’s not an organic cucmuber and you’re worried about pesticides etc, I can understand. But I’d never peel the cucumber for taste reasons. The dark dark green of the skin is rich in nutrients – especially chlorophyll.

      Enjoy the whole plant 🙂

    Where do we find all the answers to these questions, as I have the same. I’ve been told that to reduce the oxalic in spinach it’s best to steam it, not to eat it raw, so I find Caroles comment confusing. Also the grittyness is because it grows mostly in sandy soil , hence it needs lots of washing to remove it, not contributed to oxalic acid . :-/

    The oxalic acid in spinach binds to calcium to form calcium oxalate, which reduces the availability of calcium and also can also lead to the formation of kidney stones. Older leaves contain more oxalic acid than young ones, and cooked spinach seems more of a problem than raw. A gritty, chalky effect on the teeth, it is an indication of high levels of this acid.

    Hi Ross.

    Great reading – always such a pleasure – I am “112” and found out last year that I have a 11 cm circle of Emphysema on one lung. (Well I was a stupid smoker for about 50 years) anyways apart from that I have oddly enough, always been very health minded and when I found out about my problem I decided to change my eating habits even more and now do not indulge in the love of my life CHEESE nor indeed ALL other dairy produce. My lung symptoms are minimal – I drink a lot of my meals from my USA juice extractor which I love and dont eat any meat whatsoever. I still work full time, can garden all weekend and still feel full o` beans. So my message to you is GOOD ON YER. and YES SPINACH AND CO ARE THE GREATEST!! Regards from great nan xxx ps more simple but great recipes like Truman Andersons would be very much appreciated by many including yours truly. x

    Hi Ross,

    Thanks for sharing this information. I however wish to differ with you about the PH of Kale. I happen to suffer from excessive acidity and while i do agree that spinach, cucumber and broccoli help to combat my acidity, kale often worsen it. I have learnt to exclude it from my diet or use antiacid medication after eating it. While I am not implying that my problem with kale is an ultimate test of acidity in Kale, I would highly appreciate any information that would help explain why i suffer from acidity after eating kale.

    This is awesome! Thanks for your email directing me to your blog. This is so affirming! I’ve been bumping up my alkalizing food intake lately – due to joint pain I’ve been experiencing… I’d have to say that I eat your first three EVERY DAY! YUM! And Kale 2-3 times a week.

    You’re so right about spinach! You can blend it in ANYTHING. I made potato pancakes the other day and blended in spinach and basil and serano, garlic, and red onion… a little powerhouse of alkalinity!

    I blend spinach into just about every sauce I make too!

    It’s a GREAT way to get more nutrition into kids too! My brother blends greens and other veggies into the food he makes his daughter.

    Thanks for your fabulous blog and I love the bright pictures!

    I think the alkaline diet makes alot of sense, but recently I had two horrible attacks of diverticulitis and was in the hospital for several weeks, one more and my doctor will perform surgery. I know I have to change my eating habits but I am not sure which course to take. Is it safe to eat these foods? They basically told me to stay away from uncooked vegetables, salads, nuts, the skin on anything, and spicy foods? However, I did not eat much of these foods before. I mostly ate pasta. Any insight would be helpful. Thanks

    Spinach is very high in oxalic acid, and when eaten in large amounts (as in green smoothies with avocados, cucumbers etc.) could pose some serious threat to the kidneys, as when oxalic acid is present with calcium rich foods, it will form a stone.

    The Chinese culture avoids it big time, eventhough they have a good reputation for including many, many dark green vegetation in their diet.
