Since sodium also stimulates your appetite and makes you want to eat more, one simple solution to long-term weight management is to dramatically reduce your sodium intake by eating smarter. Avoid processed foods and fast foods, which are both loaded with sodium. When purchasing canned, frozen or packaged foods, look for low-sodium choices. Sodium also raises your blood pressure. If you have high blood pressure (hypertension), you probably have already been told by your physician to reduce your sodium intake.

Also, limit your sodium intake. In addition, your doctor may recommend the use of diuretics, ACE inhibitors and/or other blood pressure-lowering drugs. Take a daily multivitamin that contains B-complex vitamins. This group of vitamins lowers levels of homocysteine, an amino acid that increases the risk of stroke. Beware: Few doctors routinely test for homocysteine. Insist on the test. An average reading is approximately 10—but lower is better. People who have elevated homocysteine are two to three times more likely to have a stroke than those who have lower levels. •Take aspirin daily.

In fact, a recent study found that the following factors are to be correlated to increased hypertension: excessive sodium intake, low potassium intake, physical inactivity, low intake of fish oil, low calcium intake, low magnesium intake, excessive coffee consumption, and excessive alcohol intake.34 Dietary and lifestyle changes are the foundations of heart disease prevention and treatment. Dr. Dean Ornish and his team of researchers conducted the first significant clinical trial to determine whether comprehensive lifestyle changes affect coronary atherosclerosis. Dr.

Prevention of Hypertension • Limit sodium intake to less than 2,400 mg per day. • Practice stress management techniques. • Work toward or maintain a healthy body weight. • Exercise daily for 30 minutes or more. Prevention of Hyperlipidemia • Decrease consumption of saturated fats and high-cholesterol foods. • Increase consumption of fruits, vegetables, and whole grains. • Exercise daily for 30 minutes or more. • Increase consumption of olive oil, nuts, and seeds. ures of CVD, including decreased mortality and oxidative stress.

The DASH diet, along with a sodium intake of less than 2,400 mg per day, results in significantly lower blood pressures—systolic pressure that is 7 points lower in patients without hypertension and 11.5 points lower in those with hypertension.129 The characteristics of the DASH diet are described in Table 9.3. Caffeine. The peer pressure to become a coffee drinker is no greater than the conflicting evidence around the health impact of coffee. Some studies say it raises cholesterol; some do not.

A serving of refined sugar increases the urinary excretion of calcium,43 and an excess of corticosteroids can cause osteoporosis. High sodium intake can also cause an increase in urinary excretion of calcium in some individuals.44 Refined grains and flours may also play a part in the development of osteoporosis. Due to their lack of nutrient-rich germ and bran, there is a significant loss of vitamins and minerals in these foods. The refining process produces white flour stripped of B6, folic acid, calcium, magnesium, manganese, copper, and zinc.

It has been shown that lowering sodium intake will help lower your blood pressure, and since high blood pressure is known as "the silent killer" and a major cause of heart disease and stroke, it just makes sense. It is one of those easy dietary decisions from which you have everything to gain and nothing to lose (except excess water weight).

High sodium intake coupled with low potassium intake is an absolute disaster from the point of view of your heart.) Classic research on the In dietary supplements, you're likely to see magnesium in many forms or "salts," such as magnesium citrate, magnesium glycinate, magnesium malate, magnesium ascorbate (bound to vitamin C), and magnesium oxide. Magnesium oxide is the cheapest form and has a reputation for not being as well absorbed as the others. Magnesium glycinate is considered very high quality.

The results showed that simply cutting back on sodium intake reduced blood pressure, no matter which diet someone followed. But those on the DASH-2 diet showed greater reductions in blood pressure at each level. And the biggest reductions were in those who were hypertensive before starting the diet. Making Modifications So we know that the DASH diet works for lowering blood pressure and works even better when you lower sodium in the diet as well. But at the Hypertension Institute, they've gone the DASH diet one better.

In some cases, the extra calcium lost in urine caused by excess sodium intake is not available from the food in the intestines. When dietary calcium is not available, this 86 mg of calcium must be removed from the bones. It is estimated that as much as one percent of the bones of adult women can be lost each year for every gram of excess sodium consumed daily. With sufficient dietary calcium, this bone loss can be prevented. Calcium Depletion from Excess Protein Americans regularly consume more protein than they need.

If you determine that sodium raises your blood pressure, limit your daily sodium intake to 2.4 grams (g) (slightly more than one teaspoon of salt). •Exercise. Physical activity reduces the risk of heart disease, diabetes and hypertension— and may offer stroke protection as well. What you can do: Work with your doctor to create an exercise program based on your history of heart disease, smoking, etc. •Daily aspirin. Aspirin reduces the tendency of platelets to clump, which helps prevent blood clots that can lead to ischemic stroke.

In a typical Western diet, only 5 percent of sodium intake comes from the natural constituents in food. Prepared foods contribute 45 percent of the sodium intake, 45 percent is added during cooking, and another 5 percent is added as a condiment. Many studies have now shown that increasing dietary potassium intake or taking a potassium supplement can lower blood pressure.13 Results from thirty-three clinical trials with 2,609 participants in which potassium supplementation was the only difference between the intervention and control conditions were used in one analysis.

While the DASH diet and lower sodium intake have both been proven to reduce blood pressure, employing both strategies at the same time has shown to yield even better results. Adding more physical activity to the mix appears to reduce blood pressure even more. Think it can't get any better? Consider fiber as part of the equation, too. A low-sodium, low-fat, high-fiber diet has been linked to even larger improvements in blood pressure and body weight. In the DASH research, the diet rich in fruits and veggies provided roughly 24 grams of fiber and 1,600 calories.

Using the data collected in the DASH-Sodium trial, the variability and consistency of individual SBP responses to changes in sodium intake was examined. A total of 188 participants consumed a run-in (typical) diet at the higher sodium level and continued to eat the same diet at three sodium levels (higher: 142, intermediate: 107, lower: 65 mmol/day) sequentially in random order for 30 days each. Changes in SBP from run-in to higher sodium (no sodium level change) ranged from ?4 to +25 mmHg and 8.0% of participants decreased 10 mmHg or more.

Similarly, despite clear and long-standing recommendations to reduce sodium intake to 2400 mg/day or less, the average intake remains above 3000 mg/day. Furthermore, according to the 1999-2000 NHANES survey [204, 205], Americans are consuming far less than the nationally recommended amounts of fruit, vegetable, fiber, calcium, magnesium, and potassium—all of which are key components of the DASH dietary pattern. Clearly, implementing dietary and lifestyle modifications is challenging.

The investigators also reported a strong positive relationship between sodium intake and the slope of BP increase with age across populations [44], suggesting a role for sodium in age-related BP increase. In a reanalysis of the original LNTERSALT data, corrected for measurement error due to use of single 24-hour urine collections, results were stronger: A 100 mmol/day (2300 mg sodium) increase in urinary sodium was associated with an increase in SBP of 3-6mmHg and DBP of 0-3mmHg [45]. In a meta-analysis of observational studies, Law et al.

An individual is scored on 10 dietary parameters, most of which are shown in Table 4 (consumption of the correct number of food group servings and meeting the guidelines for fat and cholesterol; in addition, a diet is scored based on one's level of sodium intake and also for a measure of dietary variety based on the number of different food commodities that were consumed). Out of a possible score of 100, the average was 64 in 1999-2000 [59]. The score has improved slightly from 1989, when the average was 61.5, but is exactly the same as the score in 1996.

Despite greater mean reductions in sodium intake used to estimate the BP-lowering effect (a 118-mmol [2714-mg] sodium reduction in individuals with hypertension, and 160-mmol [3680-mg] reduction in nonhypertensives), their findings of a 3.9/1.9-mmHg and 1.2/0.26-mmHg BP reduction, respectively, were closer to those of Midgley et al. [48]. Graudal et al. [35] and Midgley et al. [48] included studies of short-term acute sodium reduction (which stimulates BP regulating hormones), while Cutler et al. [33] excluded these studies.

Potassium helps keep your blood pressure under control, especially when you also limit your sodium intake. Lower blood pressure means lower stroke risk. But potassium's powers go beyond its effect on blood pressure. Reduce your chance of having a stroke by up to 40 percent, simply by getting more of this natural mineral. Boosting your potassium intake to 4 grams a day can help tremendously, according to a Harvard study. That would mean eating the equivalent of about nine bananas.

Evidence presented by Donovan et al is suggestive of high sodium intake possibly exacerbating insulin resistance.75 At the other extreme, salt restriction also appears to increase insulin resistance for most individuals. While moderate dietary sodium reduction may lower blood pressure without a distinct adverse effect on glucose metabolism in subjects with primary hypertension,76 it appears that salt restriction does not improve insulin resistance in hypertensive subjects.

Limit Your Use of Salt Although some sodium is essential for survival, inadequate sodium intake is a rare problem. We need less than 500 milligrams of sodium a day to stay healthy. This is enough to accomplish all the vital functions that sodium performs in the body—helping maintain normal fluid levels, healthy muscle function, and proper acidity (pH) of the blood.

That's why it's a good idea to limit your sodium intake to 2,400 mg, or about one teaspoon of salt, a day. Don't heap all the blame on your salt shaker. Processed foods, such as frozen dinners, restaurant meals, and canned foods, contribute the most salt in your diet. If you cut down on those foods and limit the salt you use while cooking and at the table, you'll be on your way to lower blood pressure. Won't your food taste bland without salt? Not if you make some smart — and delicious — substitutions. Here are some healthy alternatives to salt. Grab some garlic.
