The Salt Intake Recommendations

You need about 500 milligrams of salt every day for your body to function. Most people take in about 10 times that amount daily. The recommended amount of salt for people with high blood pressure is about 1500 milligrams a day. Any reduction in your salt intake will help.

Is Salt Really Bad For Your Heart

“There is a fairly undisputed effect of sodium on blood pressure,” says Cook. The effect is stronger in people with high blood pressure , a sustained blood pressure reading of 120/80 or higher. The data for an effect on cardiovascular disease are somewhat more controversial, she says, but in general, the bulk of research does seem to link lower sodium intake with both lower blood pressure and a lower risk of cardiovascular disease.

How Would I Know If I Have Low Blood Pressure

The only way to tell would be to get your blood pressure checked, he confirms. Any reading under 90/60 millimeters of mercury is considered low.

However, there may be signs including:

Lightheadedness
Dizziness
Fainting

These symptoms tend to occur more when someone goes from lying down or sitting to then standing, he adds.

When Should You Limit Any Salt Including Chicken Salt

How Does Salt (Sodium) Raise Your Blood Pressure?

Our body needs just a little amount of sodium to function properly. And, limiting sodium intake is part of a healthy eating pattern. This will help to control or lower blood pressure and reduce the risk of cardiovascular disease, coronary heart attack, kidney disease and stroke.

For decades different health authorities have recommended that people should limit their salt intake to a certain quantity. However, there has been controversy about the quantity recommended since aside from the risk of overconsumption, there is also a risk of underconsumption.

The American Heart Association recommends a daily sodium intake of not more than 2,300mg, which is about 1 teaspoon of salt and 1,500mg for most adults.

The Institute of Medicine recommends a daily intake of 1,500mg of sodium for healthy adults, while World Health Organization recommends consuming 2,000mg of sodium daily.

More so, people respond to sodium differently, and those who are healthy may not benefit from limiting their salt intake. Some research has shown that limiting salt intake in healthy people may be harmful and increase their risk of heart disease.

People with hypertension, diabetes, chronic kidney disease and older adults are prone to be more sensitive to the blood pressure raising effect of salt. If you fall into this group, it is recommended that you limit your salt intake.

Myth : Pink/black/rock/sea/himalayan Salt Is Better For You Than Other Types Of Salt

You might have seen some varieties of salt advertised as having extra health benefits that regular table salt doesnt, like containing minerals that are good for your body. Consumer advocacy group CHOICE say that Australians should be wary of these kinds of health claims, as the minerals found in salts like Himalayan Sea Salt are often present only in very small amounts.

Himalayan salt, sea salt, rock salt, black salt, pink salt, unicorn salt in the end, its all still salt. Upping your salt intake to try and get the benefits of an advertised mineral might lead you to consume far too much salt, putting yourself at risk of disease.

If youre looking for a great way to get healthy minerals and other nutrients in your diet, fruits and veggies are a great source of these. Head on over to the Healthier. Happier. Colour Wheel to find out what nutrients are in your favourite fruit and veggies.

The Question Of Salt Sensitivity

Salt affects people differently. Some people can consume sodium with no effect on their blood pressure, says Dr. Thomas. But for others who are salt sensitive, even a slight increase in sodium intake wreaks havoc on the kidneys ability to regulate fluid, and increases blood pressure.

Salt sensitivity is most prevalent among people who are middle-aged or elderly, overweight or obese, and African-American. It also tends to become more prevalent as we age.

Sodium And Blood Pressure

How much salt is too much salt? AHA recommends no more than 2,300 milligrams of salt per day. This is one leveled teaspoon of salt, and the average American diet contains 2.5 times more salt, Dr. Bakris says. Thats a lot of salt being eaten.

Most of this salt comes from processed and packaged foods, not the salt shaker.

One Chinese-style meal has a tremendous amount of salt 4,000 to 8,000 mg, depending on what you order and if you are salt sensitive, your blood pressure may increase by as much as 40 points within a few hours, he says.

All that sodium in your bloodstream attracts more water into your blood vessels, which raises your blood volume. That is what causes your blood pressure to go up. Its similar to the way pressure increases in a garden hose if you turn up the spigot, the AHA notes.

Your kidney has to get rid of that salt, and it takes your kidney 24 to 48 hours to recalibrate, Dr. Bakris says. You may find yourself getting up at night to pee often because your blood pressure is elevated from salt and your kidney is trying to lower it by peeing it out.

One of the first things your doctor will recommend is modifying your lifestyle by:

Eating a low-sodium diet , especially if youre at risk.
Limiting alcohol.
Exercising regularly.
Maintaining a healthy weight.

Diuretics, or water pills, which increase urination to help discharge excess fluid.
Angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers , which help to relax blood vessels.

When added to the evidence base from longitudinal and interventional studies, these results support lowering sodium intake as part of a healthy dietary pattern, as recommended in the Dietary Guidelines.
The findings also support higher consumption of potassium-containing foods and following the Dietary Approaches to Stop Hypertension External diet or a similar diet to help lower blood pressure.

Think Twice About Table Salt

Table salt is quite high in sodium, with about 2,400 mg in a single quarter of a teaspoon. While it is not the major source of sodium in the diet, adding table salt to foods before even tasting them can bump up sodium consumption by quite a bit.

Instead, using herbs and spices to flavor foods, tasting foods before adding table salt, and considering pepper instead of salt and pepper can lower sodium content of the diet.

You can also download our free FoodSwitch app which does the hard work for you. By scanning the barcode of a product the app will tell you how much salt it contains and offer suggestions for a similar but healthier alternative.

Understanding food labels

Most of the salt we eat is hidden in the foods we buy, and similar products can vary dramatically in how much salt they contain. For example, two loaves of bread made by different companies may appear to be basically the same, but when you check the labels one contains 1g of salt per slice while the other contains half that.

Check the nutrition information on food labels to see if its low, medium or high in salt, and compare with other products to find the healthy options.

Follow these guidelines to choose lower salt foods.

Low – 0.3g salt or less per 100g – Eat plenty of these.
Medium – 0.3-1.5g salt per 100g – These are usually fine to eat, but choose low salt options where you can
High – 1.5g salt or more per 100g – Try to avoid these or eat them only occasionally

Final Word Of Caution

Every now and then, a new study comes out which questions the importance of controling sodium intake. Media outlets tend to cover such stories, as they represent a departure from what people are told at the doctors office. It is important to remember that such studies are a part of the scientific process and cannot be understood without a broader context. The issue of salt sensitivity demonstrates how there are many factors affecting blood pressure, and much remains to be studied. For the time being, the link between sodium and blood pressure continues to be a plain fact of mainstream medicql science.

Facts About Sodium Consumption And Sodium In Our Food Supply

The 20152020 Dietary Guidelines for Americans recommend that Americans consume less than 2,300 milligrams of sodium each day as part of a healthy eating pattern.6
About 90% of Americans 2 years old or older consume too much sodium.7
The average daily sodium intake for Americans 2 years old or older is more than 3,400 mg.8
Americans are consuming substantially more sodium than in the 1970s. Since 2010, some manufacturers have reduced sodium in some foods, and the amount of sodium consumed has decreased slightly in some groups of people.7,9
About 70% of sodium consumed is from processed and restaurant foods. Only a small portion of sodium or salt is used in cooking or added at the table.10
Because sodium is already in processed and restaurant foods when they are purchased, reducing personal sodium intake can be hard, even for motivated people.11
Sodium content can vary across the same types of foods by brand. For example, a slice of frozen cheese pizza can have between 370 mg and 730 mg of sodium a cheeseburger from a fast food restaurant can have between 710 mg and 1,690 mg.12
Sodium information currently is not always readily available for restaurant or prepared foods and can be hard for the consumer to estimate.
