Why Kelp Salt?

Why kelp salt instead of table salt, or plain sea salt or rock salt? The choices can be overwhelming. This article aims to give you a little more knowledge about kelp salt to help you decide what is best for you.


For years, doctors and government regulators alike have been telling us to reduce our salt intake for health reasons. They say too much salt can lead to high blood pressure, heart disease, stroke, and even death.  But is salt really the enemy, or is it the amount and type of salt that we eat which matters more? While there is still a debate on this topic, research shows the white stuff we use to flavour our food isn’t quite the evil it’s made out to be – as always, the devil is in the detail.

If you are looking for the easiest way to get started with seaweed, kelp salt has to be the simplest way to boost your iodine levels. 

Why Kelp Salt instead of Other Salts?

Pacific Harvest blends organic New Zealand sea salt with New Zealand harvested kelp granules to make a Kelp Salt. This is in essence, a naturally iodised salt without any chemical processing or interferance by humans – simply the goodness and flavours of the sea!

It is well documented that the Japanese and the Swiss enjoy some of the longest life expectancy rates of anyone in the world. It is less known however, that they also have among the highest rates of salt consumption.  Ultimately, we’d argue for the middle ground – a balanced view where we reduce risks yet still reap the health benefits that salt has to offer.

Natural sea salt has been found to be too weak in iodine to provide any substantial supplementation to our diet; but iodine is naturally plentiful in sea vegetables/seaweeds.  Pacific Harvest’s ‘Kelp Salt’, which combines the many health benefits of natural sea salt with those of kelp seaweed. Kelp Salt is a natural sea salt using iodine naturally occurring in kelp, to produce a ‘naturally iodised natural sea salt’. Its strong mineral taste is satisfying, therefore requiring a smaller amount to get the salty taste. Seaweed Salt is another option for increasing mineral content (from the seaweeds) whilst still enjoying the naturally salty flavour.

Kelp is tenderising and adds umami flavour as well as the saltiness we desire.

Low-Salt Diets May Even Be Harmful

Sodium is an essential nutrient serving a multitude of functions in the body, including helping control heart rate and aiding the transmission of signals in the brain. Too little salt may pose surprising health risks. One 2011 study, which tracked 28,880 people with heart disease or diabetes, found that those who consumed less than 2,000 milligrams of sodium a day were 37% more likely to die of heart disease than those who consumed 4,000 to 6,000 milligrams. As sodium intake drops, blood levels of cholesterol and fat can increase, escalating cardiovascular issues.

For years studies have repeatedly shown that a low-sodium diet can reduce blood pressure. But the report from the Institute of Medicine found that  this one benefit doesn’t offset the overall consequences on the body, including increased cholesterol and insulin resistance, which are thought to be the possible result of cutting almost all the salt from our diet.

Low salt diets can be especially harmful for the elderly. In older people, mild hyponatremia (low sodium concentration) is the most common form of electrolyte imbalance in the blood. Indeed, several recent medical papers have found a direct relationship between hyponatremia and unsteadiness, falls, bone fractures and attention deficits. Elderly people on low salt diets often experience lack of thirst which leads to dehydration and they experience loss of appetite that leads to a host of health problems.

How much Salt Should We Eat?

The fact remains that salts are present in most foods today – especially processed foods.  Most of us are consuming well above 2,300 milligrams of sodium, and the consequences can be serious.

As an example, studies published in the British Medical Journal showed that prehypertensive people who consumed 3,600 milligrams or more per day for up to 18 months were twice as likely to have heart attacks, strokes, or heart surgeries 15 years later, than people who reduced their consumption to 2,300 milligrams.  Another 2014 study published in the New England Journal of Medicine, tested sodium consumption in more than 100,000 people in 17 countries. The study found that the healthy range for sodium consumption was between 3,000 and 6,000 mg per day. Consuming more than 7,000 mg per day of sodium increases the risk of death or cardiovascular incidents, but not as much as eating less than 3,000 mg per day. The low salt diet was significantly more harmful than the high salt diet.

Dr. Michael Alderman and Dr. Hillel Cohen of the Albert Einstein College of Medicine reviewed 23 observational studies covering some 360,000 individuals and published their comprehensive results in the July 2012 edition of the American Journal of Hypertension. They found that both the very low and very high levels of salt consumption negatively affected health, but in between those extremes, a very broad safe range of salt consumption resulted in optimum health.

The August 14, 2014 issue of the New England Journal of Medicine summarised research on the impact of sodium (salt) consumption from 3 different studies .
More than 73 % of the countries in the world consume between 2,800-5,500 mg sodium per day (7,112-13,970 mg salt or 1¼ – 2 ½ teaspoons), where the negative health impacts are the least.

Getting Back to Kelp Salt!

Iodised salt , called ‘fake salt’ by some, can lack many of the original minerals a natural salt offers and has been supplemented with chemicals. This type of salt can cause excess fluid in your body tissues and lead to various health issues. Kelp salt adds extra nutrients and flavour to your food, and this is a natural, unprocessed way to consume it!
