It is highly advisable that we should reduce the salt (sodium chloride) in our diet to help control blood pressure and reduce risk of having a heart attack or stroke. While the amount of sodium we is important, it's not the whole story. A recent study has confirmed what other studies have suggested for years: sodium intake alone isn't as important as the ratio of sodium to potassium.
The study was reported in the January issue of the Archives of Internal Medicine. It evaluated the record of 2275 of patients who are being followed as part of the Trials of Hypertension Prevention (TOHP) studies begun in the early 1990s. What the study showed was that over a 10-15 year period, 193 participants had a serious cardiovascular episode (heart attack, stroke, need for coronary artery bypass or death due to stroke or heart attack.
They then compared the risk of these problems to the level of both sodium and potassium in the diet. They measured these levels by looking at how much of each was excreted in the urine each day. This is an easier and more accurate way to get handle on how much potassium or sodium someone is taking in than recording everything they eat. It works because our bodies maintain their internal balance of sodium and potassium by excreting any excess in the urine. The researchers found that there was little relationship between the levels of either sodium or potassium and the risk of a stroke or heart attack. What did make a difference was the ratio of sodium to potassium.
People with high sodium levels compared to their potassium levels fared the worst. They were the most likely to have a heart attack or stroke. Those with low sodium and higher potassium levels did the best. They stayed the healthiest. What does this means to you? Cut out the salt and increase your potassium. To reduce the sodium in your diet, you are going to need to read the label on any prepared foods you buy. Most packaged and canned foods are extremely high in sodium. When it comes to increasing potassium, many people thinks about bananas. Bananas are relatively high potassium, but they also are calorie dense and high on the glycemic index so they aren't my first choice to add potassium to my diet.
Here's what you do.
Drink tomato juice or a tomato based vegetable juice. One cup has about 500 mg of potassium, about the same as in a banana. Tomato juice also contains lycopenes as well as host of other nutrients. The positive effect of lycopenes on prostate health is well established so be sure to get them in your diet. Unfortunately, manufacturers usually add a lot of salt, but low salt and no-salt versions are available if you look for them. add a little potassium chloride to your tomato juice because it improves the taste and it adds some more potassium. If you do that, be a little careful - too much potassium can be toxic. Anyone who has kidney disease needs to be especially cautious and shouldn't add potassium to their diet without talking to their doctor.
Also, some enjoy the taste of horseradish and there are some studies that show the glucosinolates in horseradish and support liver function and suppress the growth of some cancer cells, so I add that to my tomatoes juice drink as well. Cut your salt intake and have a glass of tomato juice every morning and you will reduce your risk of stroke and heart attack. You will also be eating one of the nine servings of fruits and vegetable you should have everyday.
