High Animal Protein Diet Raises Risk of Negative Calcium Balance

Within the video above, James DiNicolantonio, Pharm.D., who can be the coauthor of my ebook, “Superfuel: Ketogenic Keys to Unlock the Secrets and techniques of Good Fat, Dangerous Fat, and Nice Well being,” explains why a food plan excessive in animal protein could enhance your threat of unfavourable calcium steadiness, placing your well being in danger.¹

Destructive calcium steadiness happens when your physique loses extra calcium than it absorbs. Virtually all calcium — 99% — is present in your enamel and bones, so your physique compensates for a scarcity of calcium by leaching it out of your bones.

This course of helps preserve crucial calcium ranges in your blood, which is essential for important features corresponding to muscle contraction, blood clotting and nerve transmission, however can result in weakened bones and an elevated threat of situations like osteoporosis.

“Animal meals, like meat, fish, eggs and dairy are probably the most nutrient-dense meals you possibly can eat. Nonetheless, there’s one draw back to an animal-based food plan, and that is the excessive acid load,” DiNicolantonio says. The answer, based on DiNicolantonio, is to steadiness the acid from animal meals with base.

Carnivore Eating regimen Linked to Destructive Calcium Stability Since 1930

DiNicolantonio cites a examine revealed in 1930,² which particulars Arctic explorer Vilhjalmur Stefansson’s journey of consuming solely meat for a yr.³ Over 12 durations of recorded information, “calcium steadiness was unfavourable each single time,” DiNicolantonio says. “All this proves is that since 1930 we’ve recognized that consuming an all-meat food plan — a carnivore food plan — results in unfavourable calcium steadiness.”⁴

One other instance included 10 wholesome members who consumed a strict low-carb food plan for 2 weeks, then one other carb-restricted food plan for 4 weeks that was excessive in animal protein.

This led to a lower in calcium steadiness, with the researchers concluding, “Consumption of an LCHP [low-carbohydrate high-protein] food plan for six weeks delivers a marked acid load to the kidney, will increase the chance for stone formation, decreases estimated calcium steadiness, and will enhance the chance for bone loss.”⁵

The members had been nonetheless in optimistic calcium steadiness on this case, nevertheless, which DiNicolantonio says is barely as a result of they had been consuming greater than 800 milligrams (mg) of calcium a day:⁶

“It’s possible you’ll not go in unfavourable calcium steadiness should you’re consuming over 800 milligrams of calcium and also you’re consuming a multivitamin, which seemingly accommodates vitamin D, which will increase the absorption of calcium, you might not go in unfavourable steadiness. But it surely nonetheless elevated the propensity by considerably rising the urinary calcium degree by about 100 milligram a day.

… so should you’re on a carnivore food plan you seemingly wish to eat someplace round 16 ounces of milk or three slices of cheddar cheese or a mix of the 2 to offer you about 600 milligrams of calcium as a result of then you definitely’ll get about one other 81 milligrams of calcium from consuming 1.5 kilos of meat — which is what most individuals do eat on an animal-based or carnivore food plan — round 1.5 kilos, perhaps 2 kilos, of meat per day.”

Different analysis, revealed in Calcified Tissue Worldwide, discovered that when acid ranges had been increased, on account of elevated dietary protein consumption, folks had extra acid of their our bodies and misplaced extra calcium of their urine.⁷ In the meantime, analysis exhibits high-protein diets could cause elevated calcium loss in urine, or calciuria.

In a examine of 39 premenopausal girls who lowered their protein consumption to U.S. beneficial dietary allowance ranges, acid excretion, calciuria and bone resorption had been decreased, suggesting that decrease protein consumption would possibly cut back bone loss.⁸ However as DiNicolantonio stated:⁹

“Now do not confuse this — I’m not recommending nor do I believe it’s good to eat a low-protein food plan. The thing actually, and what I do, is I eat a excessive animal protein food plan. I simply offset it with base, as a result of we all know low-protein diets aren’t good for bone well being. So, you wish to have a great protein consumption.”

The Drawback With a Excessive Acid Load in Your Physique

Diets excessive in animal proteins can produce extra acid in your physique. To neutralize the surplus acid, your physique makes use of alkaline minerals, primarily calcium. This calcium is usually mobilized out of your bones, resulting in a lower in bone density over time. Excessive acid ranges additionally enhance calcium excretion by way of urine, additional depleting your physique’s calcium reserves, which might exacerbate bone loss. DiNicolantonio explains:

“After we eat animal meals it kinds a variety of hydrogen ions (H+) or acid within the physique, which should be balanced with base (citrate or bicarbonate). If we do not steadiness the acid with base, then the physique should strip connective tissue and muscle to type ammonia in order that the kidneys can get rid of the acid.

Moreover, producing ammonia to get rid of the acid is detrimental to the kidneys. Moreover, the physique will want extra positively charged ions (like sodium, calcium, magnesium and potassium) to get rid of the negatively charged sulfate that comes from animal meals (animal meals comprise a variety of sulfur-containing amino acids).

If you don’t get sufficient positively charged ions in your food plan, then the physique will strip bone for these alkaline minerals. Moreover, a excessive acid load within the physique prompts osteoclasts to interrupt down bone and it lowers the pH within the interstitial fluid (the fluid that surrounds our cells), which might trigger insulin resistance. In different phrases, should you do not steadiness the acid from animal meals with base you possibly can trigger:

• Kidney injury
• Insulin resistance
• Bone breakdown
• Mineral loss
• Kidney stones”

Metabolic Acidosis Drives Power Illness

Metabolic acidosis occurs when your physique produces an excessive amount of acid or your kidneys usually are not eradicating sufficient acid out of your physique. Excessive consumption of animal protein can enhance the manufacturing of sulfuric acid because of the metabolism of sulfur-containing amino acids present in meat, poultry and fish. Based on DiNicolantonio:¹⁰

“Metabolic acidosis is a continual situation that many individuals within the Western world have however don’t notice it … A standard wholesome physique has quite a few buffering programs to fight acid accumulation.

Nonetheless, in case your buffering capability is decreased or can not meet the acid load, then harms can ensue corresponding to a breakdown of muscle, connective tissue and bone … Animal protein is the most important supply of dietary acid as it’s excessive within the sulfur-containing amino acids methionine and cysteine, which ends up in the formation of sulfuric acid and hydrogen ions within the physique.”

Even low-grade metabolic acidosis can result in:¹¹

DiNicolantonio factors out that the common western food plan results in a web acid excretion of fifty to 100 milliequivalents (mEq) per day (milliequivalent measures the focus of ions in an answer). Nonetheless, “The kidneys of a wholesome individual can solely excrete 40-70 mEq of acid per day earlier than acid is retained within the physique,” he says. “Most Individuals are consuming diets that produce this a lot acid or extra per day.”¹³

Additional, “Animal-based or carnivore diets usually present 150-250 mEq of acid per day, which implies that a lot of these diets result in important acid retention until exogenous bicarbonate forming substances are being consumed (bicarbonate mineral waters or dietary supplements, fruits or greens).”¹⁴

How one can Stability Dietary Acid With Base

What you eat impacts your physique’s acid base steadiness, and sustaining a food plan that balances acid and alkaline meals might help defend your well being.

“Animal protein, significantly, meat, eggs and cheese, is what results in the formation of enormous quantities of acid within the physique,” DiNicolantonio says. “Vegatables and fruits are excessive in natural anions like citrate, malate and gluconate, which get transformed to bicarbonate within the physique. Bicarbonate is the bottom in our physique that neutralizes the acid.”¹⁵

Whereas I do not advocate vegan or vegetarian diets, together with extra vegetables and fruit, that are alkaline, might help counteract acid load. DiNicolantonio says, “I personally attempt to neutralize the acid from my food plan by calculating how a lot acid goes to be produced from the meals I eat.” For instance:

As a rule, protein ought to make up about 15% of your every day energy. Extra particularly, most adults want about 0.8 grams of protein per pound of supreme physique weight (the load you’ll ideally be, not essentially the load you are actually), or for Europeans, roughly 1.76 grams of protein per kilo.

For instance, in case your supreme weight is 135 kilos, your protein requirement can be 108 grams. Divided into two meals, that might be 54 grams per meal. For reference, there’s roughly 7 grams of protein in every ounce of steak, so a 5-ounce steak would offer you 35 grams of high-quality protein. For youngsters, the common quantity per meal is round 5 to 10 grams, whereas younger adults usually can get away with 20 grams per meal.

For many normal-weight adults, 30 grams per meal is admittedly the minimal that you must stimulate muscle protein synthesis. The secret’s to steadiness the acid load from animal meals in your food plan with pure compounds that assist neutralize the acid. Along with vegetables and fruit, DiNicolantonio recommends:¹⁶

• Sodium citrate — 5 grams (g) suppresses 60 mEq of acid. Needs to be taken with meals.
• Potassium citrate — 3 g suppresses 30 mEq of acid. Usually, not more than 3 g is taken with every meal.
• Bicarbonate mineral waters (low in sulfate) — 1 mEq of bicarbonate inhibits 1 mEq of acid. “Usually, the bicarbonate ranges are pretty low and mustn’t have an effect on abdomen pH. There’s a sluggish accumulation of bicarbonate within the physique when consuming bicarbonate mineral waters and this can be a higher choice than sodium or potassium bicarbonate dietary supplements.”
