How Much Sodium Is Too Much?
While you might hear the words salt and sodium used interchangeably, there is a difference between the two. Salt is a combination of two minerals, sodium (40 percent) and chloride.
In a recent post highlighting seven foods that experts once said were bad that turned out to be healthy, we are reminded that sodium is, in fact, essential to health. It is necessary for good digestion, it supports thyroid function, controls muscle and nerve function, regulates water balance and helps metabolize food. Unrefined salt like raw sea salt can contain dozens of trace minerals. In fact, salt was once so valuable that it was literally used as currency.
Reaching for the salt shaker for another shake? Might not be a bad idea? Well first consider this:
Think that your sodium intake is low because you don’t add a lot of salt when you cook? Well sodium is hidden in lots of foods. While it might not be news to you that a fast food sandwich can easily contain more than 100 percent of the sodium you need in a day, it might surprise you to find out the top 10 sources of sodium in the diet. In fact, 44 percent of the sodium we eat comes from just these 10 types of food.
According to the Centers for Disease Control and Prevention (CDC), the top sources of sodium in the diet include:
- Breads and rolls
- Cold cuts and cured meats
- Pasta dishes
- Meat dishes
In addition, sodium is included in one’s diet in surprising ways. For instance, most store-bought raw chicken and pork has been injected with a sodium solution to add weight and moisture. Think that’s odd? It’s a fact. But check out these 7 salty myths:
So, what’s the right amount?
The CDC offers current dietary guidelines for American adults in which less than 2,300 mg of sodium is consumed per day.
However, the CDC adds, if you are in the following population groups, you should consume no more than 1,500 mg of sodium per day:
- 51 years of age or older
- African American
- Have high blood pressure
- Have diabetes
- Have chronic kidney disease
Four years ago, the American Heart Association (AHA) lowered its suggested daily sodium intake from 2,300 mg a day to less than 1,500 mg a day. With this reduction, the AHA estimates a savings of more than $426 billion in healthcare costs and a 25.6 percent decrease in high blood pressure across the population.
As far as a sodium deficiency, it’s rare. Only people involved in vigorous exercise in hot environments need to be concerned about replacing sodium lost through perspiration.
Need some pointers, hints and tricks to track, monitor or reduce your sodium intake?

How much sodium is in salt?
1/4 teaspoon salt = 600 mg sodium
1/2 teaspoon salt = 1,200 mg sodium
3/4 teaspoon salt = 1,800 mg sodium
1 teaspoon salt = 2,300 mg sodium
1 teaspoon baking soda = 1000 mg sodium

More tips from AHA
- Don’t forget to check the nutrition labels on prepared and packaged foods, because up to 75 percent of the sodium we consume is hidden in processed foods. Watch for the words “soda” and “sodium” and the symbol “Na” on labels, which mean sodium compounds are present.
- If you’re going to eat pizza, try a cheeseless pizza with lots of veggies.
- Use fresh, skinless poultry that isn’t enhanced with sodium solution instead of fried or processed chicken.
- When choosing soup, try lower-sodium varieties.
- Make your sandwiches with lower-sodium meats and low-fat, low sodium cheeses, and try not to pile on the condiments.
- Choose foods with potassium to counter the effects of sodium. It may help lower your blood pressure.
That last point, choosing foods high in potassium, is important. The CDC also encourages the consumption of potassium-rich foods, such as fruits and vegetables. Dr. Oz contributor Daniel Heller, ND, reinforces that eating more potassium is just as important as reducing sodium:
The two minerals are like the two sides of a seesaw, or like yin and yang. They balance each other out. Many of the negative effects of excess sodium can also be traced to insufficient potassium. While cutting back on sodium chloride, we should also be eating more fruits and vegetables, which are rich sources of potassium bicarbonate.

A powerful volcano on Monday rocked an uninhabited island frequented by tourists about 30 miles off New Zealand's coast. Authorities have confirmed that five people died. They expect that number to rise as some are missing and police officials issued a statement that flights around the islands revealed "no signs of life had been seen at any point,", as The Guardian reported.
"Based on the information we have, we do not believe there are any survivors on the island," the police said in their official statement. "Police is working urgently to confirm the exact number of those who have died, further to the five confirmed deceased already."
The eruption happened on New Zealand's Whakaari/White Island, an islet jutting out of the Bay of Plenty, off the country's North Island. The island is privately owned and is typically visited for day-trips by thousands of tourists every year, according to The New York Times.
My god, White Island volcano in New Zealand erupted today for first time since 2001. My family and I had gotten off it 20 minutes before, were waiting at our boat about to leave when we saw it. Boat ride home tending to people our boat rescued was indescribable. #whiteisland pic.twitter.com/QJwWi12Tvt— Michael Schade (@sch) December 9, 2019

At the time of the eruption on Monday, about 50 passengers from the Ovation of Seas were on the island, including more than 30 who were part of a Royal Caribbean cruise trip, according to CNN. Twenty-three people, including the five dead, were evacuated from the island.
The eruption occurred at 2:11 pm local time on Monday, as footage from a crater camera owned and operated by GeoNet, New Zealand's geological hazards agency, shows. The camera also shows dozens of people walking near the rim as white smoke billows just before the eruption, according to Reuters.
Police were unable to reach the island because searing white ash posed imminent danger to rescue workers, said John Tims, New Zealand's deputy police commissioner, as he stood next to Prime Minister Jacinda Ardern in a press conference, as The New York Times reported. Tims said rescue workers would assess the safety of approaching the island on Tuesday morning. "We know the urgency to go back to the island," he told reporters.
"The physical environment is unsafe for us to return to the island," Tims added, as CNN reported. "It's important that we consider the health and safety of rescuers, so we're taking advice from experts going forward."
Authorities have had no communication with anyone on the island. They are frantically working to identify how many people remain and who they are, according to CNN.
Geologists said the eruption is not unexpected and some questioned why the island is open to tourism.
"The volcano has been restless for a few weeks, resulting in the raising of the alert level, so that this eruption is not really a surprise," said Bill McGuire, emeritus professor of geophysical and climate hazards at University College London, as The Guardian reported.
"White Island has been a disaster waiting to happen for many years," said Raymond Cas, emeritus professor at Monash University's school of earth, atmosphere and environment, as The Guardian reported. "Having visited it twice, I have always felt that it was too dangerous to allow the daily tour groups that visit the uninhabited island volcano by boat and helicopter."
The prime minister arrived Monday night in Whakatane, the town closest to the eruption, where day boats visiting the island are docked. Whakatane has a large Maori population.
Ardern met with local council leaders on Monday. She is scheduled to meet with search and rescue teams and will speak to the media at 7 a.m. local time (1 p.m. EST), after drones survey the island, as CNN reported.
