Shake the Salt Habit during American heart month to ensure a healthy heart

The health of your arteries is critically important to virtually every aspect of your health. Too much salt (sodium) ages your cardiovascular system by raising your blood pressure and hardening, stiffening and thickening your arteries and the walls of your heart. You want to keep your blood vessels soft, smooth and supple like they were when you were a child and a teenager and avoid developing the rigid, inflamed and crusty pipes that can lead to a heart attack, stroke and congestive heart failure.

As an American adult, your chances of developing high blood pressure during your lifetime are 90 percent. If you continue to follow your current lifestyle, sooner or later you will probably get hypertension-the medical term for high blood pressure. Why? For starters, the average American consumes about 4000 mg of sodium daily, which is about six to ten times more salt than we were designed to eat. Add the fact that blood pressure rises in response to too much body fat, stress, and sugar and too little sleep and exercise, and you have the recipe for high blood pressure. In February 2005, the Center for Science in the Public Interest estimates that too much sodium kills 150,000 Americans each year. Excess sodium does much more that just raise your blood pressure. A study by David Calhoun, MD, reported in February 2005 Cardiology News showed that high-sodium intake reduced blood vessel wall function. In addition, salt leaches the calcium from your bones, making you prone to osteoporosis and fractures, and also appears to increase cancer risk- especially in the GI tract. A recent study found that extra salt in the diet increased the likelihood of heartburn (also known as esophageal reflux) by as much as 70 percent.

A good place to start lowering the sodium in your diet is by removing the salt shaker from the table and hiding it in an inconvenient spot. But only about 5 percent of the salt in our diet comes from the salt shakers; 75 percent comes from processed and restaurant foods. Most people do not choose to eat high-sodium products- they just eat foods that are readily available in our culture. Salt is everywhere in our modern diet, even in foods such as bread that don’t taste salty. Processed foods are loaded with salt to help preserve freshness, and the more sodium you eat, the more you will crave salt. When you eliminate highly processed, high- sodium foods from your diet, you will take a huge step toward a healthier more vigorous life.

Fresh fruits and vegetable contain virtually no sodium and thus are great for lowering your blood pressure along with your weight. We recommend at least nine servings of fresh produce daily. Unprocessed meat, poultry and fish contain only small amounts of sodium, but the more highly processed versions like deli meats, smoked, or barbecued meats, beef jerky and other commercially modified meats are usually very high in salt. The processed snack foods are generally also high in sodium. Try to get used to eating nuts that are unsalted or only lightly salted. Look for the sodium content on food labels and avoid items that have more than 400 mg per serving. Limit your daily intake to not more than 2300 mg (about one teaspoon) – the average American eats almost two times this much. One glass of regular V8 vegetable juice has over 1000 mg by itself. (low-sodium V8 or tomato juice is great) and a single dill pickle has 440 mg. A high potassium-to-sodium ratio is one of the most important parameters of a healthy diet. We are designed to take in much more potassium than sodium, but the ratio is reversed and sodium dwarfs the potassium consumption. So how do you get more potassium? You guessed it-lots of fruits, vegetables, lean protein and other Forever Young natural whole foods.

The D Days of Summer

Tuesday, June 16th, 2009

By Joan O’Keefe, RD

Summer is unofficially here and now is the time to make a choice. How are you going to spend it? Are you going to sit indoors watching reality television or are you going to improve your health by getting outside?

That’s right. Sunshine will actually improve your health. When you’re outdoors on a sunny day, not only do you get to breathe fresh air, relax, take a break from stress, and enjoy the landscape, you’re improving your vitamin D levels as well. Unlike other vitamins and nutrients, Vitamin D is actually made inside our bodies in response to sunlight. It turns out, humans are solar-powered. Our mood, immunity and risk for major diseases are all affected by our Vitamin D levels. Vitamin D deficiency is linked to diabetes, obesity, high blood pressure, weaker bones, higher risk of heart attacks, increased asthma risk, increased chances of developing the metabolic syndrome and increased risk for certain cancers, particularly breast and colon. Vitamin D affects our cognitive performance and is indicated in dementia. Everyday aches and pains are oftentimes symptoms of inadequate Vitamin D.

Vitamin D boosts immunity. Our ancestors were hunter-gatherers; they were outside all day with no sunscreen and were physically active. Now we’re hunkered down in houses and offices all day. Now, we need antibiotics for everything. It is against human nature to be inside all day. When we lived and worked outside, the sunshine was our natural immunity booster.

The choice is yours. All it takes is about 20 minutes of sunshine (no sunscreen) per day to soak up the vitamin D. If your skin is very dark, you are obese, or elderly, you may need more time. I recommend you visit your doctor and KNOW YOUR NUMBERS. Vitamin D levels are easily checked with a simple blood test. Ideally, vitamin D levels should be between 50 and 70. Keeping your levels in this range is tricky. Lifestyle plays a role in our vitamin D levels. You have to be vigilant about sun exposure (during the summer months – it is impossible to make vitamin D in the winter months above 37 degrees latitude – around Atlanta, GA). I recommend a supplement with 2,000 IU Vitamin D3 daily, especially if you are not getting adequate sun exposure every day.
