“The ideal amount of celery juice for most adults is a minimum of 16 ounces per day. Not that you have to or necessarily want to start with 16 ounces the first time you try it. Feel free to work your way up, starting with 4 or 8 ounces if you’re sensitive and from there increasing it a little every day as you get used to it. Once you’re ready, it is a good idea to commit to those 16 ounces as a minimum. Why? Because most people have more than a few health obstacles to overcome. The celery juice must travel quite a distance on its journey. Its first obstacle is often in the mouth, with bacteria or leftover toothpaste, mouthwash, or mouth rinse. (Make sure to thoroughly rinse your mouth with fresh water after brushing your teeth and before drinking celery juice to get rid of any toothpaste, mouthwash, or mouth rinse residue. Even better, wait to brush your teeth until after you’ve had your morning celery juice.) Then there’s the esophagus, where the celery juice encounters additional bacteria plus deposits of ammonia and unproductive, detrimental acids. Next it reaches a hurdle at the bottom of the stomach pouch, just before the duodenum (the entrance to the small intestine). There’s a little ledge right before the duodenum, and depending on someone’s age, that alone can be filled with decades—sometimes 30 to 40 years’ worth—of debris that has gummed up and weighed down that little cliff. This debris could be from proteins, fats, preservatives, solidified ammonia, acids, and more, all of it corroding and formed into a sludgy deposit. Celery juice’s sodium cluster salts start eating away at this old pile of toxic sludge, slowly dissolving it over time. So first the celery juice has to get through those obstacles. Then, as the celery juice is moving through the duodenum, it’s usually met with a barrage of H. pylori, Streptococcus, and other varieties of bacteria—because most people live with undiagnosed cases of these bacteria. Celery juice has to fight to sustain itself and stay active in this battle, which is doubly hard since it was already defused from dealing with toothbrushing residues and bacteria in the mouth; ammonia, acid, and more bacteria in the esophagus; and debris as it left the stomach. As it continues through the duodenum, celery juice is bombarded with acids, since most everybody’s pH is “off” internally in this day and age. It’s not like we’re automatically alkaline. Sure, if someone’s healthy, their pH will be pretty balanced, and celery juice won’t have to do much work in this respect. Most people are filled with bacteria, though, and that’s a big acid producer. Unproductive diets and punishing stress levels are acid producers, too. As soon as we take our first sip, celery juice starts altering the internal pH of the body, beginning with the mouth and continuing down the digestive tract. It’s almost like an explosion as celery juice tries to turn the tide of high acidity, and that’s yet one more source that defuses it in its travels through our system. Sound like a lot for celery juice to encounter and keep up its strength? There’s more. Just a few inches farther in the small intestinal tract, celery juice encounters a slick of mucus. It’s there in young and old alike—a layer of bottom feeders like strep and E. coli and other unproductive bacteria, usually along with two to three unproductive funguses, all of them just waiting for protein from eggs or supplemental collagen that we consume, or lactose from milk, cheese, butter, or other dairy, so the bugs can feed on them. When celery juice instead hits this pathway of pathogens, it’s yet one more area of battle. Plus, there are rancid fats that have hardened and caked along the intestinal wall linings from years of high-fat foods, whether from healthy or unhealthy fat sources, as well as rotting protein that has formed into little balls of debris and created pockets in the intestinal tract that guard more bacteria and funguses. Addressing all of this is yet one more series of obstacles for celery juice during its travels. That’s not even everything; it only describes the major hurdles that celery juice encounters so far. Then add in excess adrenaline—say, if you ate on the run or under stress, with tension in your gut, or if you ate too much fat with your meal the night before without realizing it, any of which prompts the adrenals to release a burst of adrenaline. When this excess adrenaline enters the intestinal tract, it’s a scorcher. It saturates cells all through the body, so if you were under intense stress or encountered another adrenal trigger the day before, when you wake up the next day, the adrenaline is still sitting in the intestinal tract. Celery juice works on neutralizing this adrenaline: yet one more battle. While celery juice will try to handle it, that’s a tall order considering everything else it went through as it traveled along through the gut. A high-fat dinner does more than trigger adrenaline. Fats left over from dinner linger in the gut, from the stomach to the small intestinal tract to the colon, like an oil slick, and celery juice is up against those, too. High levels of these fats soak up celery juice’s healing compounds, using up sodium cluster salts, since they must go to work dispersing those fats and cleaning them out of the digestive tract. This means that if someone has an extra heavy dinner, maybe with something fried for the main course followed by dessert, celery juice will need to work extra hard the next morning, and that will diminish some of its healing power as it continues on the obstacle course. The digestive system was only the beginning. The majority of the world is also dealing with stagnant, sluggish livers, and here’s the critical part: enough celery juice has to make it to the colon with its potency intact to be absorbed into the bloodstream so celery juice’s compounds can travel through the hepatic portal vein into the liver and then into the gallbladder—to help you heal. Regardless of what you’re dealing with in life, a healthier liver means a greater chance of healing any variety of symptom or condition you’re up against. Sixteen ounces is the magic number to do this for the majority of adults. (More soon on amounts for children.) Once celery juice does get to the liver, it encounters another set of hurdles. For one, most people’s livers are toxic with poisons, pesticides, herbicides, plastics and other petrochemicals, solvents, pathogens such as viruses and bacteria, and many more troublemakers. All of this strains the liver’s bile production. When celery juice’s compounds enter the bile production area, if they’re still potent enough, they will improve the strength of the bile that the liver sends to the gallbladder. This celery juice–bolstered bile then starts dismantling and dispersing sludge in the gallbladder while also breaking down and dissolving gallstones. If you’ve been drinking large enough quantities of celery juice for long enough to get your system clean and healthy, celery juice’s compounds will then leave the gallbladder with the bile as it’s released into the intestinal tract. This is part of celery juice’s responsibility: to come full circle. Not all of celery juice’s healing components that make it to the liver get directed to the bile. Some leave the liver through the bloodstream, heading up to the heart and brain, although their healing abilities by this point are pretty minimal if someone has a sluggish or stagnant liver, which most people do. It takes time for someone to clean up the liver to the point that celery juice’s components still hold benefits as they exit this way. That’s okay, though, because celery juice has another way of getting its potent components to the bloodstream. Back when celery juice was first in the digestive tract, only some of it—roughly half— traveled to the liver in the first place. It divided itself on the obstacle course. While traveling through the stomach and the first 36 inches of the small intestine, the other half of celery juice’s chemical compounds absorbed into the digestive tract walls and entered the bloodstream directly without going to the liver first. Traveling through the blood is its own set of hurdles. How much fat is in the blood? (Fats interfere with celery juice’s travel distance.) How many toxins are in the blood? How many toxic heavy metals are inside various organs such as the brain? Speaking of the brain, how many neurotransmitter chemical issues are occurring there? All of this defuses and weakens any strength that celery juice has left. If neurotransmitter chemicals in the brain are diminished, celery juice’s compounds get used up in instantly replacing them, making this their final destination, in a way. If heavy metals need to be dislodged, celery juice’s sodium cluster salts get consumed with helping them out of the body. Given the gargantuan scope of celery juice’s job, you can see why you’d want to drink enough of it to get that job done. The next time someone is quizzing you about why you drink this particular amount of celery juice, well, it’s up to you. You could give them the play-by-play of its travels through the digestive tract and beyond (in which case you probably want to make sure they aren’t eating!). You could give them the condensed version: celery juice has huge responsibilities and an obstacle course to overcome as it travels through your body and works on healing it. Or you could hand them this book. Whichever you choose, now you know, and that’s critical, because connecting to the “whys” of celery juice makes it all the more powerful.” Excerpt from Medical Medium Celery Juice: The Most Powerful Medicine of Our Time Healing Millions Worldwide.
