Celery juice is the single most foundational ingredient in green vegetable juice on the Primal Diet. It is not a beverage in the conventional sense, it is a concentrated mineral supplement, a blood-serum regulator, a negative-carbohydrate cleansing agent, and a sodium normalization tool. Aajonus placed it at the center of every vegetable juice formula he developed and recommended it as the dominant ingredient, typically comprising 55% to 90% of any given juice blend, particularly in the first two to six years on the diet.

The primary role of celery juice within the Primal Diet is threefold: first, to provide a mineral concentration almost identical to blood serum, effectively acting like a natural intravenous supplement that regulates and alkalinizes the blood from within the digestive system; second, to function as a negative-carbohydrate agent that actively pulls toxic sugars and excess stored sodium out of the body without adding carbohydrate load; and third, to serve as the base vehicle through which other high-chlorophyll vegetables, parsley, cilantro, comfrey, zucchini, and eventually cucumber puree, deliver their concentrated vitamins, enzymes, and minerals to the body in a fully bioavailable, fiber-free form.

Aajonus explicitly stated that vegetable juice is a supplement for vitamins, enzymes, and minerals, not a fuel source. It must remain low in carbohydrate so the body uses the nutrients for cellular repair, digestion, and mineral balance rather than burning them as energy. Celery is the key ingredient that keeps the entire juice formula in that low-carbohydrate therapeutic zone, even when small amounts of higher-carbohydrate vegetables like carrot or parsley are added.

The single most emphasized biochemical property of celery, repeated across dozens of recorded workshops and writings, is that celery does not contain enough carbohydrate to even digest the celery itself. This means that in metabolic terms, celery functions as a negative-carbohydrate food. The body must draw on existing carbohydrate resources to process the celery fiber, meaning celery effectively removes carbohydrate from the system rather than adding to it.

Aajonus stated this in multiple formulations:

This property makes celery juice uniquely suitable as the dominant ingredient in a morning vegetable juice blend that must stay below the carbohydrate threshold that triggers glucose-as-fuel metabolism. The first six to seven hours of the day, after the long overnight sleep, were identified by Aajonus as the period when advanced glycation end products (AGEs) form most readily if high-carbohydrate foods are consumed. Celery juice bypasses this problem entirely because of its negative-carbohydrate status.

Because celery is a negative, adding even high-carbohydrate ingredients like carrot to it results in a net low-carbohydrate juice. For example, mixing equal parts celery and carrot juice produces a carbohydrate level that is "even OK", not high enough to cause a sugar fuel response, not so negative as to strip too much glycogen.

Aajonus repeatedly stated that the mineral concentration in celery juice is almost identical to blood serum, not blood cells, but blood serum specifically. This is the biochemical basis for calling vegetable juice with high celery content essentially a natural IV drip.

This near-perfect match to blood serum means the body can absorb and deploy the minerals from celery juice with minimal processing overhead. The blood is immediately supported without any digestive burden from fiber or high sugar content, which is why Aajonus recommended celery juice particularly in the morning, first thing, before any food, to address the highly acidic blood state that accumulates overnight as the body detoxifies through the bloodstream during sleep.

Celery is extremely high in sodium, but the sodium in fresh raw celery is in its organic, food-form state, which Aajonus described as the smallest molecular mineral in the body. This is in direct contrast to salt, whether Celtic salt, Dead Sea salt, or any other concentrated mineral salt form, which clumps into large molecular structures that damage red blood cells, burn nerve endings, and age the body from within.

This is the second major mechanism by which celery juice works: it introduces highly bioavailable organic sodium that the blood can actually use to maintain proper electrolyte balance, while simultaneously pulling out the old, toxic, crystallized rock-salt-form sodium that has accumulated in tissues throughout a lifetime of cooked-food eating. The body can identify and process the organic sodium from celery, use what it needs for electrolyte balance, and deploy the remainder as a chelating agent to draw out the old toxic concentrated salt deposits.

The negative carbohydrate function of celery juice extends into active detoxification: because there is less carbohydrate in celery than the body needs to metabolize celery, the body pulls carbohydrate from existing stores to complete the process. This means celery juice draws sugar out of the blood and out of storage, including toxic sugars, damaged sugars, and excessive glycogen, when the body has an excess.

This is an important distinction with significant practical implications: for high-carbohydrate individuals with decades of accumulated toxic sugars, this drawing-out effect is therapeutic and necessary. But it is time-limited. Once the toxic sugar burden has been cleared, which can take anywhere from two to six years depending on the individual, the body no longer benefits from this aggressive drawing-out function. At that point, continued high-celery juice consumption begins pulling out the body's own healthy sugars and glycogen, causing fatigue, listlessness, and weakness.

Morning blood is described by Aajonus as highly acidic, "acrid", due to the overnight dumping of metabolic waste products, heavy metals, and toxins into the bloodstream. This acidic blood state produces the characteristic morning irritability, lethargy, and unwillingness to engage socially that many people experience. Celery juice addresses this directly.

By rapidly alkalinizing the blood through its mineral delivery, matched precisely to blood serum concentration, celery juice restores the acid-base balance in the bloodstream within minutes of ingestion. This is why Aajonus recommended it first thing in the morning, before food: it clears the acidic blood condition that would otherwise interfere with digestion and mood throughout the day.

Aajonus noted that watermelon juice has a mineral profile with similarities to celery juice, but that watermelon is too high in sugar to serve as a therapeutic substitute.

During travels in Southeast Asia, Aajonus was unable to obtain vegetable juice and tested raw sugar cane juice as an alternative. He found, to his surprise, that it produced virtually identical results to celery juice, with no sugar reaction even at 16 ounces:

His explanation: the sugar molecule in cane is only released from the cellulose when boiled at 450-700 degrees Fahrenheit. Raw, uncooked sugar cane juice delivers juice in essentially the same metabolic form as celery juice, all the mineral and fluid benefits with essentially no bioavailable sugar.

In a Q&A response, Aajonus acknowledged that celery does contain aldosterone, a hormone relevant to sodium regulation. He confirmed that, over time, he had reduced his own vegetable juice consumption:

This is the only instance where he acknowledged a reason for long-term reduction beyond the toxic-sugar-depletion explanation. The aldosterone content was raised by a questioner citing other researchers, and Aajonus acknowledged the concern without fully disputing it.

Celery juice must be freshly juiced to preserve enzyme activity. Once dried, as in celery salt, the structure is entirely altered. Celery salt is not celery-form sodium at all:

Dried celery loses its enzyme activity rapidly. Aajonus said that while dried herbs can still provide some oils, minerals, and even medicinal value, and historically were used when fresh plants were unavailable, they will not provide the enzyme activity that fresh celery juice delivers. The comparison to dried herbs is made directly:

Celery must be juiced, not blended. Blending in a device like a Vitamix introduces oxygen into the food, oxidizing approximately one-third of all nutrients. Additionally, blending does not separate the pulp from the juice, meaning the cellulose fiber remains in the mixture. For celery specifically, consuming the pulp/fiber with the juice causes a problem that Aajonus identified as directly harmful to intestinal bacteria:

This is why juicing removes the pulp: the goal is to extract the fluid-borne minerals, vitamins, and enzymes without the fiber that would pass through the intestine and interfere with the acidic bacterial environment required for meat digestion.

The recipe book formulas specify "fresh celery stalks (with leaves if not wilted)." Wilted leaves are excluded. Fresh, non-wilted leaves are included in the juice.

Aajonus made the striking observation that celery is not fed to any other animal, including vegetarian animals:

This is relevant to how the body handles celery's mineral-pulling mechanism, it works for humans because of the accumulated toxic salt burden that humans carry from a lifetime of cooked food and processed salt consumption. For animals not carrying this toxic burden, celery's aggressive salt-drawing and mineral-stripping action would be harmful rather than therapeutic.

Aajonus recommended the Green Star 1000 juicer (double stainless steel auger system) as the best option for juicing celery and other vegetables. It operates in a hermetically sealed environment that prevents oxidization. The Green Power Juicer (larger version) was recommended for families. Centrifugal juicers were explicitly criticized because they introduce oxygen (air) during pressing, causing oxidization of approximately one-third of nutrients.

Celery is easy to juice, Aajonus described pushing it down into the juicer: "Celery. Push it down in. So easy." When juicing hard or difficult vegetables alongside celery, he recommended alternating them, pushing the difficult vegetable in together with celery stalks so the celery's easy flow helps pull the harder produce through the gears.

For people in climates where celery cannot grow easily (such as Hawaii, where rain causes celery to split), Aajonus suggested green papaya as a base substitute:

Sugar cane juice was also identified as a functional field substitute when vegetable juice was completely unavailable (see Properties section above).

The standard sequence Aajonus recommended was: eat a small amount of raw no-salt-added cheese approximately ten minutes before drinking vegetable juice. The purpose is to absorb and neutralize toxins in the digestive tract before they can be reabsorbed:

For the liver/lymphatic/glandular detox formula (which contains lemon and cilantro), Aajonus specified:

This fat buffer is required to protect the digestive system from the concentrated acids and detoxifying agents in the formula.

Aajonus described his own morning juice preparation as including an egg and a tablespoon of cream, with the yolk broken with a fork:

For heart conditions or athletes using juice, he specified: "you need to put an egg in it, and a tablespoon of broth to slow it down."

In all formal juice recipes in the recipe book, unheated honey is included. The stated purpose is preservation as well as sweetening:

---

Formula: - 1 raw celery stalk, blended - 2 tablespoons grated raw horseradish root

Application: Apply as a poultice to a painful joint. Expected result: Most often reduces pain within 20 minutes. Indication: Arthritis, volatile toxin-related joint inflammation with soreness or pain.

---

Celery percentage: 70-80%, up to 90%

Total daily volume: Aajonus recommended one to four cups of vegetable juice daily, depending on individual needs and red meat consumption. Those who don't eat much red meat were advised to drink more juice.

Frequency: Daily

Duration: Two to six years, depending on how much high-carbohydrate and processed food was consumed in prior life. High-carbohydrate individuals may need the full six years. Some people reach the depletion point in as little as two years.

Warning sign that Phase 1 is complete: Fatigue, tiredness, or feeling out of sorts after drinking the juice. The juice begins drawing healthy sugar instead of toxic sugar.

Signal: Feeling fatigued or listless after juice consumption.

Action: Reduce celery significantly. Increase cucumber puree. Add carrot.

New ratios: - Celery: reduce to as low as 20%, maximum 25% - Cucumber puree: increase to 30-40% - Carrot: increase to 10-20% - Parsley/cilantro: maintain at 5-10%

Total celery percentage floor: 20% minimum (do not go below this)

If still fatigued even at 20% celery: Add more carrot (15-20%) and ensure cucumber puree is at 40%.

Aajonus himself, over many years, reduced his own vegetable juice intake substantially:

This represents a dramatic long-term reduction from daily multi-cup consumption to approximately one quart per week total, a reduction of about one cup every seven years as a gradual tapering protocol.

Even in recipes heavily weighted toward other vegetables, Aajonus specified that celery should comprise at least 25% of any vegetable juice blend:

Children under 15 should only have vegetable juices occasionally, if necessary for a specific ailment or following a cold or flu, and if consumed regularly, no more than once every 10-22 days. If a child is raised on raw food from birth, vegetable juices may not be necessary at all.

1. Juice celery stalks and all other vegetables (carrot, parsley, cilantro, zucchini, beet, everything except cucumber) 2. Pour the fresh juice into a jar containing peeled, sliced cucumber (if using cucumber) 3. Blend the juice together with the cucumber slices (this creates a pulpy juice, do not juice the cucumber separately) 4. Add egg and cream if desired, break yolk with fork before adding 5. Stir or shake to combine all ingredients 6. Pour into storage jars immediately 7. Can last three to four days refrigerated (honey helps preserve) 8. Shake jars before each use, as cucumber pulp will separate

• Use jars with lids to prevent oxidization
• Prepare multiple days at once (juice lasts 3-4 days with honey as preservative)
• Shake before serving to redistribute cucumber pulp

• Always peel the cucumber, whether organic or not
• Slice or cube into jar
• Juice all other ingredients separately
• Pour the fresh vegetable juice into the jar with the cucumber
• Blend cucumber and juice together, this is the "puree" method
• Do not juice the cucumber in the juicer, must be blended to retain the pulp for collagen precursor delivery

Celery and its juice can be added to sauces and other preparations as a natural sodium source:

---

Aajonus specifically and emphatically excluded celery salt as a form of celery. It is not a valid substitute or derivative:

Celery salt loses all enzyme activity, all mineral balance, and all bioavailability. It becomes a concentrated mineral salt, the very thing Aajonus warned against consuming in any form.

In the Primal Diet Newsletter, Aajonus addressed the product "Quinton", collected and diluted ocean water sold in glass ampoules, bottles, and aerosol containers. Marketers claimed it mirrors the mineral plasma of living tissue. Aajonus used celery juice as his counter-reference:

The argument: the mineral similarity between ocean water/celery juice and blood plasma is not a reason to bypass the digestive system. The digestive tract reconstructs substances appropriate for the individual body. Injecting or directly infusing even a perfectly mineral-matched substance is categorically different from ingesting it and allowing the body to process it through its natural systems.
