Potassium is essential for the normal functioning of all cells. It regulates heart rate, ensures proper muscle and nerve function, and is vital for protein synthesis and carbohydrate metabolism.
Thousands of years ago, when humans roamed the land, gathering and hunting, potassium was abundant in the diet, while sodium was scarce. The so-called Paleolithic diet supplied about 16 times more potassium than sodium. Today, most Americans get barely half of the recommended amount of potassium in their diets. The average American diet contains about twice as much sodium as potassium, due to the preponderance of salt hidden in processed or prepared foods, not to mention the lack of potassium in those foods. This imbalance, which is contrary to how humans evolved, is believed to be the main cause of high blood pressure, which affects one in three American adults.

The recommended adequate intake of potassium is 4,700 mg. Bananas are often touted as a good source of potassium, but other fruits (such as apricots, prunes, and orange juice) and vegetables (such as squash and potatoes) contain this often-neglected nutrient.
Diets that emphasize a greater intake of potassium may help keep blood pressure in the y range compared to diets poor in potassium. The DASH (Dietary Approaches to Stop Hypertension) study compared three regimens. A standard diet, which approximates what many Americans eat, contained an average of 3.5 daily servings of fruits and vegetables, providing 1,700 mg of potassium per day. There were two comparison diets: a diet rich in fruits and vegetables, which included an average of 8.5 daily servings of fruits and vegetables, providing 4,100 mg of potassium per day, and a “combined” diet, which included the same 8.5 servings of fruits and vegetables plus low-fat dairy products and reduced sugar and red meat. In people with normal blood pressure, a diet rich in fruits and vegetables lowered blood pressure by 2.8 mm Hg (systolic reading) and 1.1 mm Hg (diastolic reading) more than the standard diet. The combined diet reduced blood pressure by 5.5 mm Hg and 3.0 mm Hg more than the standard diet. In people with high blood pressure, the combination diet lowered blood pressure even more, by up to 11 mm Hg in systolic pressure and 5.5 mm Hg in diastolic pressure.
High blood pressure is a major risk factor for stroke, so it’s no surprise that higher potassium is also associated with lower stroke rates. One prospective study, which followed more than 43,000 men over eight years, found that men who consumed the highest amounts of dietary potassium (an average of 4,300 mg per day) were 38% less likely to have a stroke than those whose average intake was only 2,400 mg per day. However, a similar prospective study that followed more than 85,000 women for 14 years found a more modest association between potassium intake and stroke risk. Additional research has mostly confirmed these findings, with the strongest evidence supporting a high potassium diet in people with high blood pressure and in blacks, who are more prone to high blood pressure than whites.

Potassium is a super essential mineral in the body, so I want to go over what it is, what it can do, and how important it really is.
Why is this so important? Number one, because we need so much. Of all the nutrients – vitamin A, vitamin B, calcium, magnesium – potassium is needed in the largest amount in the body. I’m talking about 4700 mg a day.

Potassium is used in almost all cellular reactions in the human body. It is also used to store sugar in the liver and muscles. Now let’s explain what I mean. Stored sugar in the muscles is a good thing. In order to handle the quick release of energy we need for many daily tasks, we need to be able to store some sugar.
Is a sugar molecule. If you put many of these molecules together in a group, they are called
. So glycogen is basically a storage of glucose. It happens mainly in the liver and muscles and is used very immediately and very regularly in the body.
Now, it just so happens that potassium is the mineral that allows glucose to be stored as glycogen. So for every molecule of glucose you need one molecule or element of potassium.
Potassium (k+) In Blood And Its Significance
So that’s one really important reason why we need enough potassium in the body. If you have low potassium or suffer from hypokalemia, you will also not store glucose. And if you’re not storing glucose, your body will be less efficient and start storing more fat for energy.
Also, if you have enough potassium, you won’t crave sugar. Why? Because you’ll be able to store sugar like you should and you’ll have better blood sugar levels. This is because potassium stabilizes your blood sugar so you don’t have regular peaks and troughs in your blood sugar.
If you have a sweet tooth, we know you may have hypokalemia, so you could benefit from more potassium.
When you consume potassium, you also help balance sodium in your body. In general, we need a potassium to sodium ratio of 4:1 to function effectively. Most people have the opposite ratio, with too much sodium and too little potassium. As a result, they retain fluids and have other symptoms.
Chemical Composition Of The Human Body
Specifically, people who retain fluid are “salt sensitive,” meaning they have high blood pressure. Thus, hypokalemia can lead to high blood pressure.
