Sea Salt vs. Table Salt: Which Is Healthier?
By Terita Heath-Wlaz
Time for a dash of salt on that sheet pan of roasted veggies. What do you reach for? Pink Himalayan crystal salt? Hawaiian red salt? Black lava salt? Or, good old Morton's table salt?
Colorful, exotic sea salts are marketed as minimally-processed, healthful alternatives to refined table salt. But since your individual diet and health influences what you need from salt, it's worth examining the claims and true differences among salts before you choose.
Processing in Sea Salt vs. Table Salt
It's true that sea salt undergoes less processing than table salt; it's produced simply by evaporating water from oceans or salinated lakes. Trace minerals like potassium, calcium and magnesium remain in sea salt, altering its texture, flavor and nutritional content in subtle ways.
Table salt, on the other hand, is mined from salt deposits underground. Manufacturers strip the salt of minerals to yield a uniformly white color, grind it to a fine consistency and add an anti-caking agent like calcium silicate. Finally, most table salts contain added iodine to combat iodine deficiency and goiter.
Many consumers gravitate toward sea salt because of its “close-to-nature" status–and its easy to understand why! We know minimal processing benefits our health when it comes to grains, meats and vegetables, so shouldn't the same be true for salt?
There's more to consider.
The promise of trace minerals in sea salt is alluring, but experts with the American Heart Association note that most minerals in sea salt occur plentifully in other foods. If you eat a varied diet rich in fruits, vegetables, whole grains and legumes, you likely already consume plenty of potassium, magnesium, calcium and other nutrients.
By weight, the amount of sodium in sea salt and table salt is roughly equal. That means if you're trying to keep your sodium intake below the recommended limit of 2,300 milligrams per day, use either type of salt in moderation.
Worthy of note: most sodium we ingest doesn't come from the salt we add to food, but from packaged and processed food. The most effective change you can make to reduce sodium intake is to eat fewer processed foods and less restaurant fare.
Dietary iodine added to table salt—but not sea salt—protects the health of your thyroid, which in turn helps regulate your metabolism, heart rate, nervous system and many more functions.
Certain foods supply iodine naturally, including seaweed, fish, yogurt and eggs. If you eat these foods regularly (especially seaweed!), you may be getting the recommended 150 micrograms of iodine your body needs in a day.
If your diet is low in iodine, however (which is common), choosing iodized table salt might act as a good insurance policy for thyroid health.
So, What Should I Choose?
The salt you choose depends on your tastes, nutritional status and diet. If you are neither pregnant nor breastfeeding and you regularly eat iodine-rich foods, you might choose sea salts for their beautiful array of colors, textures and flavors. A little jar of special salt makes a charming gift and if you enjoy eating foods close to their natural state, sea salt can complement your cooking.
But sea salt, unlike table salt, does not supply iodine and its trace minerals probably have little effect on your health. Most importantly, remember that sea salt contains as much sodium as table salt, so whatever you choose, use just a sprinkle!

Global Banks, Led by JPMorgan Chase, Invested $1.9 Trillion in Fossil Fuels Since Paris Climate Pact

A report published Wednesday names the banks that have played the biggest recent role in funding fossil fuel projects, finding that since 2016, immediately following the Paris agreement's adoption, 33 global banks have poured $1.9 trillion into financing climate-changing projects worldwide.

2018 was a groundbreaking year in the public conversation about climate change. Last February, The New York Times reported that a record percentage of Americans now believe that climate change is caused by humans, and there was a 20 percentage point rise in "the number of Americans who say they worry 'a great deal' about climate change."

Ask any resident of San Francisco about the waterfront parrots, and they will surely tell you a story of red-faced conures squawking or dive-bombing between building peaks. Ask a team of researchers from the University of Georgia, however, and they will tell you of a mysterious string of neurological poisonings impacting the naturalized flock for decades.
The initial cause of the fire was not yet known, but it has been driven by the strong wind and jumped the North Santiam River, The Salem Statesman Journal reported. As of Tuesday night, it threatened around 35 homes and 30 buildings, and was 20 percent contained.
The unanimous verdict was announced Tuesday in San Francisco in the first federal case to be brought against Monsanto, now owned by Bayer, alleging that repeated use of the company's glyphosate-containing weedkiller caused the plaintiff's cancer. Seventy-year-old Edwin Hardeman of Santa Rosa, California said he used Roundup for almost 30 years on his properties before developing non-Hodgkin's lymphoma.
"Today's verdict reinforces what another jury found last year, and what scientists with the state of California and the World Health Organization have concluded: Glyphosate causes cancer in people," Environmental Working Group President Ken Cook said in a statement. "As similar lawsuits mount, the evidence will grow that Roundup is not safe, and that the company has tried to cover it up."
Judge Vince Chhabria has split Hardeman's trial into two phases. The first, decided Tuesday, focused exclusively on whether or not Roundup use caused the plaintiff's cancer. The second, to begin Wednesday, will assess if Bayer is liable for damages.
"We are disappointed with the jury's initial decision, but we continue to believe firmly that the science confirms glyphosate-based herbicides do not cause cancer," Bayer spokesman Dan Childs said in a statement reported by The Guardian. "We are confident the evidence in phase two will show that Monsanto's conduct has been appropriate and the company should not be liable for Mr. Hardeman's cancer."
Some legal experts said that Chhabria's decision to split the trial was beneficial to Bayer, Reuters reported. The company had complained that the jury in Johnson's case had been distracted by the lawyers' claims that Monsanto had sought to mislead scientists and the public about Roundup's safety.
However, a remark made by Chhabria during the trial and reported by The Guardian was blatantly critical of the company.
"Although the evidence that Roundup causes cancer is quite equivocal, there is strong evidence from which a jury could conclude that Monsanto does not particularly care whether its product is in fact giving people cancer, focusing instead on manipulating public opinion and undermining anyone who raises genuine and legitimate concerns about the issue," he said.
Many regulatory bodies, including the U.S. Environmental Protection Agency, have ruled that glyphosate is safe for humans, but the World Health Organization's International Agency for Research on Cancer found it was "probably carcinogenic to humans" in 2015. A university study earlier this year found that glyphosate use increased cancer risk by as much as 41 percent.
Hardeman's lawyers Jennifer Moore and Aimee Wagstaff said they would now reveal Monsanto's efforts to mislead the public about the safety of its product.
"Now we can focus on the evidence that Monsanto has not taken a responsible, objective approach to the safety of Roundup," they wrote in a statement reported by The Guardian.
Hardeman's case is considered a "bellwether" trial for the more than 760 glyphosate cases Chhabria is hearing. In total, there are around 11,200 such lawsuits pending in the U.S., according to Reuters.
University of Richmond law professor Carl Tobias told Reuters that Tuesday's decision showed that the verdict in Johnson's case was not "an aberration," and could possibly predict how future juries in the thousands of pending cases would respond.
