Hypertension is becoming more common in children. We previously discussed how this has been happening. It is often unnoticed because the way hypertension is determined in children is different than in adults. High potassium foods should correct this. More evidence is found in a recent medical article (1).
In the report, 335 children were studied. They were examined at 18 months and then again at 8 years and some (201) at 9 years also. Their diet was examined and compared to their blood pressure.
What was surprising in the article is that you don't have to wait until adulthood to see the effects of sodium and potassium levels in the diet. The changes can be seen already in childhood, at 8 and 9 years of age.
For all the kids, the higher the dairy, the lower the blood pressure. The kids with the highest intake of dairy had the highest intake of calcium, magnesium and potassium, and also had the lowest blood pressure, both systolic and diastolic. The kids with the lowest dairy intake had the highest blood pressure.
Dairy is a high potassium food, except for cheese which has too much sodium and not enough potassium. Look here for a table with the nutrient values of dairy foods.
The problem of high blood pressure in children has been growing over the past few decades. This has corresponded to the increase in sodium and the reduction in potassium intake seen over the same period that results from eating out more (almost all is high sodium and low potassium food) and eating more processed foods. The changes in our lifestyle make a big difference in what we eat, and what consequently happens to our bodies.
By changing to a high potassium diet, many favorable effects will result. The expected results of eating more potassium and less sodium are that we will be less likely to have hypertension, cardiovascular disease and strokes, and our bones will be stronger. This all starts in childhood when we are conditioned to prefer certain types of foods. The discussion of this is here.
For a list of all the food tables showing the amount of potassium in different foods, as well as showing other posts, look here.
