Proper potassium balance essential to healthy blood pressure and reduced heart attack risk



by: John Phillip

(NaturalNews) Increasing incidence of high blood pressure continues to be the most significant factor in death from a heart attack and advancing cardiovascular disease. Elevated blood pressure readings cause thickening of the coronary arteries as micro-cracks develop that the body attempts to correct with deposits of coronary plaque. Overweight and obesity, smoking, physical inactivity and stress are known contributing factors to the hypertension epidemic. Researchers publishing in the Archives of Internal Medicine found that the imbalance of potassium to sodium in the diet is a significant factor driving high blood pressure. Maintaining an optimized ratio of 2:1 (potassium to sodium) by cutting salty processed foods and increasing natural fruits and vegetables is shown to significantly lower out of control blood pressure readings.

Potassium from natural food sources has been rapidly depleted from the typical diet due to the dramatic rise in sodium-laden processed foods over the past half century. Combined with a reduction in raw vegetables and fruits that are excellent sources of potassium, the balance of potassium to sodium in the diet has shifted from an ideal ratio of 2:1 to a blood pressure raising rate of 2:3. Current potassium intake is fully one-third that of our generational ancestors and is attributed to the skyrocketing increase in high blood pressure incidence and associated cardiovascular risk.

Researchers examining the potassium intake across 21 countries including the US found that average daily consumption of the mineral ranged from 1.7 to 3.7 grams, well below the recommended daily allowance of 4.7 grams. Similarly, sodium consumption averaged 5 grams per day with many individuals taking in as much as 9 to 12 grams. The recommended sodium intake is 2,400 mg daily and 1,500 mg or less is suggested for those with established cardiovascular risk factors.

The study found that only 20% to 30 % of the adult population maintains normal blood pressure readings. The study authors found "An effective way of increasing potassium intake is to follow the guidelines for healthy nutrition more closely, including a higher consumption of vegetables and fruit. In addition, the use of mineral salts in processed foods - by which sodium is partly replaced by potassium - would contribute to an improved intake of both sodium and potassium."

The study concluded that increasing potassium in the diet has a significant effect on lowering blood pressure and is equal to the effect seen by lowering sodium consumption. Higher potassium intake from natural sources including avocados, spinach, carrots and tomatoes and elimination of sodium-infused processed foods (snacks, soup and fast food) can combine to lower systolic blood pressure readings by 5% to 7%. Improving this single risk factor could reduce hypertension rates enough to dramatically lower cardiovascular risk and heart attack deaths.

After a heart attack - A healthy heart starts with great nutrition

(NaturalNews) Going through a heart attack can be a harrowing experience. With symptoms ranging from heart palpitations, cold sweats, fatigue, and anxiety a heart attack is downright frightening with 40% of sufferers not surviving the episode. Survivors must make long term lifestyle changes immediately or risk another cardiac event. In a culture of fast living and fast food long term changes can be difficult to obtain.

A heart attack, or myocardial infarction, occurs when blood flow to certain areas of the heart is interrupted causing a shortage of oxygen in the heart tissue. Stress, sedentary habits, and diets high in unhealthy fats are prominent factors. A recent study conducted by researchers from the University of Missouri, Kansas City shed light on an interesting but unfortunate phenomenon. They found that of the 884 patients that frequently ate fast food before their heart attack, 503 of them continued to do so despite their recent attacks. Is this a matter of mere unhealthy convenience or something more?

It is no secret that fast food is a hodge-podge of chemically laced and genetically modified ingredients. The importance of the chemical aspect of the food is how it interacts with the brain, potentially leading to addictions or cravings. At the top of the list of addictive substances is MSG and any of its derivatives. MSG acts on different areas of the brain including the hypothalamus, which controls appetite and satiety. When damaged or otherwise diminished, the hypothalamus is unable to properly control not only our appetites, but also how much we eat. Also, consuming saturated fat and sugar in high amounts are thought to hijack natural brain processes causing the overproduction of opioids. Opioids are produced naturally by the brain, but overproduction can give way to self intoxication leading to addictions much like you would see in heroin addicts (not nearly as strong but powerful none the less).

For those poor souls who find it difficult to stay away from fast food let's order up a few suggestions. First, it is imperative to increase the consumption of good fats, also known as essential fatty acids (EFA's). Doing so in combination with reducing or eliminating saturated and trans fats will provide proper nutrition, satiety and relief for the hypothalamus allowing time for the gland to restore itself. Besides nourishment and boosting brain health EFA's also bind toxins helping to rid the body of inflammatory substances. Also, one should avoid MSG and any of its variants (i.e. autolyzed yeast extract). MSG is a documented neurotoxin that has the ability to overwhelm areas of the brain that control appetite such as the hypothalamus as mentioned earlier. Finally, decreasing sugar intake will go a long way in fighting cravings for foods that aren't healthy to consume. When blood sugar is kept at a steady level, as opposed to spiking and crashing, most cravings stop or become controllable.

A healthy heart starts with great nutrition. Without doubt anything resembling nutrition will not be found in a bag of fast food. Fast food is not only cheap and plentiful, but it is also engineered to make you want it and generally against your own best interest. Be good to your heart and let not your heart be troubled.
