DASH diet effective but not the only way to reduce sodium

Your body needs a little bit of salt every day for the sodium it contains. But too much sodium can boost blood pressure and stress the heart and blood vessels. The low-sodium Dietary Approaches to Stop Hypertension (DASH) diet is high in fruits, vegetables, and whole grains; moderately high in nuts and low-fat dairy products; and low in red and processed meats. Following it can lower blood pressure and reduce the risk of heart disease and stroke.

The DASH diet is a good way to eat healthy. But there's no need to follow that specific diet to get measurable results. If you want to tackle cutting back on sodium, try these six tips:

Keep unhealthy foods to minimum, balanced with nutritious choices

What exactly is a healthy diet? The basics are pretty simple. Everyone needs a mix of proteins, carbohydrates, and fats, plus enough vitamins and minerals for optimal health. But science is revealing that some of the food choices within these categories are better than others.

Go slow on unhealthy foods

Are there foods you never should eat? Not really. If you crave an ice cream sundae occasionally, have a small one. But don't make it a daily event. Offset the chips you ate at your neighbor's barbeque with healthier snacks at home. Healthy eating doesn't mean eliminating certain foods altogether. However, there are some things that are best eaten only rarely.

Nuts are a good source of plant fats and protein, but they are high in calories. It’s a good idea to limit nut consumption to 1 ounce per day.

Here's how to keep your daily salt intake in check.

Most men probably consume too much sodium, and new federal guidelines are aimed at helping them curb their habit.

The FDA advises no more than 2,300 milligrams (mg) of sodium daily—the amount in about 1 teaspoon of salt. (People with prehypertension and hypertension should limit their intake to 1,500 mg, roughly the amount in 3/4 tea-spoon of salt.)

A new study found that high levels of omega-6 fatty acids in the subcutaneous adipose tissue—the layer of fat just beneath the skin—correlated with lower death rates among older men. Omega-6s mostly come in the form of linoleic acid, found in plant oils (such as corn, soybean, and sunflower oils) as well as nuts and seeds. Linoleic acid is known to shrink levels of bad LDL cholesterol in the blood, which can contribute to lower incidence of heart disease.

Q. I love dried fruit and thought it was healthy. But I hear that you gain a lot of weight eating dried fruit, which is not healthy. What's the truth?

A. The truth is that the actress and comedian Mae West was wrong when she allegedly said "Too much of a good thing ... can be wonderful!" Food contains calories, and eating too many calories-even of healthy foods-leads to weight gain. But there are healthy calories and unhealthy ("empty") calories, and fruit is a healthy source of calories. That's as true of dried fruit as fresh fruit.

The new Nutrition Facts labels will list “added sugars” in a serving of food. Until the labels appear, one should look for sugars such as dextrose and sucrose on a label’s list of ingredients.

Stick to fresh foods, and fill your salt allotment from healthy sources like whole-grain breads.

As we reported in August 2016, the FDA is encouraging the food industry to cut back on added sodium in commercially processed and prepared food. It's a good reminder for all of us that too much salt in the diet is risky for health. How much is too much? "It's controversial, although I don't think anyone is in favor of unlimited salt intake," says Dr. Randall Zusman, a cardiologist with Harvard-affiliated Massachusetts General Hospital.
