When Dr. Loren Cordain first launched the idea of Paleolithic diet, the scientific analysis illustrated the significance of three essential nutrient ratios: omega-6 to omega-Three fatty acids, calcium to magnesium, and sodium to potassium (Na+/Ok+). The proof instructed these three ratios had been fairly totally different in a Paleolithic weight loss plan when in comparison with a typical Western weight loss plan. Moreover, the ratios present in a Paleolithic weight loss plan had been much more useful to human well being.
Now we have written extensively at The Paleo Weight-reduction plan® relating to our concern that the higher Paleo neighborhood has, with little scientific help, embraced the notion that it’s acceptable to devour sodium portions above governmental tips (for instance, by way of the copious addition of sea salt to many “Paleo Licensed” meals objects).
Paleolithic diet usually doesn’t align with authorities tips. Nevertheless, on this occasion, there may be settlement between The Paleo Weight-reduction plan’s scientific place—pure meals in primitive and present occasions present low sodium portions—and authorities suggestions for sodium consumption.
Why the sodium/potassium ratio is so vital
Offering our physiology with meals that match our genetically decided dietary necessities is likely one of the major tenets of a Paleolithic weight loss plan. Dietary mismatches may end up in well being issues.
The Western weight loss plan is low in plant meals containing potassium alkali salts (Ok-base), which our ancestors ate in abundance. Concurrently, trendy diets comprise meals that change these Ok-base salts with sodium chloride (NaCl). Because of this, in a typical Western weight loss plan the ratio of sodium to potassium is commonly 1-to-1, and lots of occasions worse.
As talked about, the ratio of sodium to potassium is essential for our well being. A rise in dietary sodium will increase the sodium/potassium ratio even when advisable ranges of potassium are consumed. Extra usually there may be inadequate potassium consumption, which compounds the difficulty by driving the ratio farther from our pure ratio of about 1-to-5 to 1-to-10.
Each cell in our physique depends on an intricate steadiness of sodium and potassium. In 1957, scientists found what is known as the Na+-Ok+ pump, discovered within the outer plasma membrane of just about each cell. It’s accountable for pumping three sodium ions out of the cell and two potassium ions into the cell. ATP (the power forex of the human physique) is required to carry out this trade. These pumps keep a better focus of sodium extracellularly (exterior the cell) and a better focus of potassium intracellularly (contained in the cell), which is essential for the physiological processes of all cells in our physique. We might die if this excessive focus gradient, with sodium exterior of the cells and potassium inside the cells, was not maintained.
An understanding of the significance that sodium and potassium play in mobile operate makes clear that a shift away from our genetically decided dietary necessities can have dire penalties for our well being.
Well being penalties of a poor sodium/potassium ratio
A weight loss plan that’s low in potassium and excessive in sodium will increase the web systemic acid load on the physique. This then results in a continual metabolic acidosis, which has detrimental results on the physique, together with development retardation in youngsters, decreased muscle and bone mass in adults, and kidney stone formation. Correction of this acidosis can reverse these situations (1).
Many proponents of decreased animal protein consumption argue that such a weight loss plan creates metabolic acidosis. Nevertheless, earlier findings that confirmed a correlation between hip fracture incidence and animal protein consumption in older girls had been negated by the consumption of plant meals (1). Many plant meals are excessive in potassium.
This discovering is supported by a more moderen research demonstrating that whereas dietary acid load is related to continual kidney illness (CKD), potassium consumption was negatively related to CKD, and protein consumption had no affiliation with CKD (2).
A evaluation of the scientific literature is overwhelmingly supportive of lowering sodium whereas concurrently growing potassium for improved well being advantages. Regardless of dietary tips of the identical suggestion, it was decided that lower than zero.zero15 p.c of the inhabitants met the objectives (Three). Newer findings reveal an enchancment from this quantity, however nonetheless present that solely about 10 p.c of American adults have a Na+/Ok+ ratio in line with the WHO tips for decreased threat of mortality (four).
A big physique of analysis helps the affiliation of a excessive Na+/Ok+ ratio with a rise in hypertension (5, 6, 7, Eight). Moreover, it has been discovered that low sodium and excessive potassium consumption reduces blood stress in hypotensive, normotensive, and hypertensive people (9).
A excessive Na+/Ok+ ratio has additionally been associated to urinary stone illness (10)—a threat issue for and a predictor of CKD (11, 12). Likewise, an elevated ratio is related to a rise in weight problems (13) and is said to excessive insulin resistance and low insulin sensitivity (14). It has additionally been recognized as a threat issue for stroke (15, 16, 17), and even all-cause mortality (17, 18).
What this analysis demonstrates is that the Na+/Ok+ ratio is a crucial consider your well being, and methods for lowering sodium consumption and growing potassium consumption are prudent. A method of bettering that is by way of decreased consumption of contemporary condiments and ultra-processed meals (19). Fortunately you possibly can keep away from them with little effort and simply lower the ratio by following the rules and recipes right here at The Paleo Weight-reduction plan® web site. And don’t fear about together with recent meat in your weight loss plan. A really current research from Eire confirmed recent meats, however not cured and processed meats, are related to a decrease Na+/Ok+ ratio (20).
