The High Performance Handbook Is Like Nothing You've Ever Seen Before...

Today’s guest post on sodium intake comes from current Cressey Performance intern, Jordan Syatt.
Sodium intake is a highly controversial topic within the fitness industry, mainstream media, and even the medical community. Very simply, everyone wants to know: “Is salt bad for you?” Nobody seems to have a clear-cut answer.
While many are quick to demonize the tasty mineral, I’ve long wondered if the evils associated with salt are the result of poorly constructed and misinterpreted research or actual cause for concern.
In an attempt to settle the debate once and for all, I began to dig up all the research I could find pertaining to sodium intake, high blood pressure, cardiovascular disease, and general health.
To make things as simple as possible, I’ve outlined my findings below. I think the results may surprise you!
Sodium Intake: What Does the Research Say?
First and foremost, high-blood pressure is perhaps the most prevalent risk factor associated with cardiovascular disease (CVD). Bearing in mind that CVD is currently the world’s leading cause of death, any information we can find to aid in reducing the risk of CVD is of the utmost importance.
Therefore, considering it is well established that diets excessively high in sodium may result in increased blood pressure (BP), it should come as no surprise that doctors and health professionals alike strongly encourage maintaining a low-sodium diet in the long-term. Epidemiological research suggests high-salt diets may not only affect blood pressure (BP) and thereby cardiovascular disease (CVD), but could also “increase the risk of stroke, left ventricular hypertrophy and renal disease.”
Perhaps worst of all, great sodium consumption tends to cause water retention, thus giving leaner individuals a noticeably “softer” appearance. In other words, their abs won’t appear to be as cut-up.
What the hell, salt!?!?
Based on the information provided above, it would appear as though high-salt diets are the primary cause of illness, death, and guys making excuses for why they don’t look as lean as they should.
We should probably cut it out of our diet, right?
Not so fast.
While high BP is certainly a major risk factor of cardiovascular disease, recent research has clearly shown the ratio of sodium intake to potassium intake within the diet has a much greater effect on BP than sodium (or potassium) alone.
While excessive sodium consumption can have a negative impact on BP (thus increasing one’s risk of various diseases), simply increasing the amount of potassium consumed on a daily basis holds the same benefits as lowering salt intake. As low-sodium diets are rather difficult to maintain in the long-term, placing an emphasis on potassium-rich foods may help individuals keep BP in check without causing undue stress notably in social situations.
In addition to the ratio of salt to potassium within the diet, other factors such as age, gender, genetics, activity level, and body fat are tremendously significant in determining ones risk of high BP, CVD, and other related illnesses. Not surprisingly, exercise and weight loss significantly reduce the risk of CVD. As such, rather than solely focus on reducing salt intake, beginning an appropriate training routine and maintaining a healthy body weight would most likely be the ideal first step in preventing CVD.
Finally, one need only look at the extremely high amounts of sodium in processed foods to understand why greater sodium consumption is associated with high BP and CVD. I’d venture to guess that those individuals who base their diets largely on processed foods are not only consuming too much salt, but are also not eating enough potassium, neglecting to exercise, failing to get an adequate amount of sleep, not maintaining an appropriate body weight, nor living a healthy lifestyle in general.
Taking the above into consideration, is it really the heavy sodium consumption causing high BP and CVD? Or, could it possibly be the overall sedentary lifestyle, overconsumption of processed foods, being overweight, etc?
I bet it’s the latter.
If otherwise healthy individuals are eating a diet largely consisting of whole/unprocessed foods, consuming adequate potassium, regularly exercising, and maintaining a healthy bodyweight, they can probably stop worrying over the minutia and feel free to add a dash, or two, of the ever-so-tasty mineral.
My General Recommendations:
Individuals should maintain a diet largely consisting of whole/unprocessed foods and make a concerted effort to acquire enough potassium on a daily basis. Examples include, but are not limited to, baked potatoes, cooked spinach, bananas, oranges, and cooked beans. For a detailed list of potassium-rich foods, click HERE. Additionally, I encourage individuals to follow an appropriate strength and conditioning program designed specifically for their individual needs.
Note: those who already have high blood pressure, first and foremost, you must consult with your primary care physician and follow his/her directions, as various anti-hypertensive medications can interact differently with food and exercise. Plus, you want to find out why you are hypertensive in the first place in order to individualize your treatment approach.
