Why Iodine is Important for Heart Health

  This post may contain affiliate links

In a small coastal village, two men, lifelong friends, faced starkly different fates. One, robust and hearty, lived well into his old age, while the other suffered from heart complications and passed away prematurely. 

Curiously, their diets, though similar, had one significant difference: one consumed abundant seafood rich in iodine, while the other did not. This anecdote mirrors the findings of recent studies highlighting the crucial role iodine plays in heart health.

What is Iodine?

Iodine is a vital nutrient that our bodies need to stay healthy. It’s like a tiny helper that makes sure our thyroid gland, which is in our neck, works well. The thyroid gland is like a control center for our body, managing how fast we burn energy and how we grow. 

The human body can’t make iodine, so we must get it through our diets. Without enough iodine, our thyroid can’t do its job properly, which can lead to health problems. Just like we need the right ingredients to make a recipe work, our bodies need iodine to keep everything running smoothly. 

Iodine and the Heart

Though a tiny element in our diet, iodine plays a giant role in maintaining heart health. While its primary function is to produce thyroid hormones, the influence of iodine stretches beyond the thyroid. Iodine directly impacts heart health.

Heart Problems Associated with Low Iodine Levels

  • Coronary Artery Disease (CAD): One of the most significant findings from recent studies is the link between low iodine levels and an increased risk of coronary artery disease. 

    Coronary artery disease occurs when the arteries that supply blood to the heart muscle become hardened and narrowed due to plaque buildup. This condition can lead to chest pain, shortness of breath, and, in severe cases, heart attacks. 

    Research indicates that individuals with lower levels of iodine have nearly twice the likelihood of developing CAD compared to those with higher iodine levels.  

  • Dyslipidemia: Dyslipidemia is when there’s an unhealthy balance of fats in our blood, and it’s connected to not having enough iodine. 

    Think of it like this: our blood carries different types of fats. Too much LDL cholesterol and not enough HDL cholesterol can clog our blood vessels. This clogging, or plaque buildup, can increase the risk of serious heart problems, including heart attacks and strokes. So, keeping the right balance of these fats is crucial for our heart health, and iodine plays a key role in this.

    A 2016 study of nearly 2,500 adults found that individuals with the lowest amount of iodine in their urine had a 51 percent higher likelihood of elevated total cholesterol, a 58 percent greater chance of increased LDL cholesterol, and a 66 percent increased risk of a lower HDL/LDL ratio, compared to those with higher iodine levels. This significant finding underscores iodine’s impact on lipid metabolism and heart health. 

Nature’s Bounty: Wild Salmon Roe and The Whole Fish

In our quest for heart health, nature offers its bounty. Wild-caught seafood is an excellent natural source of Iodine. Unfortunately, most seafood we see at grocery stores or restaurants is farm-raised and filled with antibiotics and unhealthy additives. Moreover, eating enough fish to obtain the proper amounts of iodine can be challenging. That’s where supplements step in. Wild Salmon Roe and The Whole Fish supplements stand out as phenomenal sources of Iodine. 

Salmon roe, in particular, is not only a rich source of iodine but also provides omega-3 fatty acids, known for their heart-protective properties. Our Pacific Wild Salmon Roe comes in convenient, mess-free gel capsules with no fishy taste, no need for refrigeration, and no added ingredients – just pure, healthful salmon roe.

The Whole Fish captures the complete nutritional power of sardines in a unique, freeze-dried capsule, offering the entire fish – from brain to bones – with minimal fishy taste or smell, perfect for those who aren’t fond of seafood’s taste, lack access to quality fish, or don’t consume it regularly. It’s an all-natural way to enjoy the benefits of sardines without any additives.

Next Steps

The research is clear: Iodine is crucial for maintaining heart health. It’s a reminder of the wisdom in nature’s design, where the proper nutrients are often available in the foods around us. We can take proactive steps towards heart health by incorporating iodine-rich supplements like  Wild Salmon Roe and The Whole Fish.

The tale of the two fishermen is not just a story; it reflects the profound impact our dietary choices have on our health. Embracing nature’s gifts, particularly Iodine, could be the key to a healthier heart and a longer, more vibrant life.

About Dr. Lauren Lattanza NMD, FACC

Dr. Lattanza Office Visit with Patient

As a Naturopathic Physician, I am trained to treat the whole person and get to the root cause of disease.

I went to Arizona State University where I graduated with a bachelor’s degree in psychology with a depth in physiology and minor in Spanish. After my undergraduate degree I was working on prerequisite classes towards medical school, which is when I came to learn that my values identified best with the principles of naturopathic medicine. I knew that I wanted to help patients identify the causes of disease and be able to offer treatments which would improve their health rather than simply treating symptoms.

I dedicated the next 4 years to the Southwest College of Naturopathic Medicine in Tempe, Arizona where I attained my Doctorate of Naturopathic Medicine. I served as Class President all 4 years, Board of Trustees – Student Trustee, spoke as the Club President for our branch of Toastmasters, and was voted by my peers and attending physicians to earn the Outstanding Leadership Award for the Class of 2020. Throughout medical school I took it upon myself to work alongside MDs, DOs, chiropractors, and functional medicine practitioners in addition to naturopathic physicians.

As a Spanish speaking student, I was able to volunteer with community clinics around Phoenix and provide free healthcare to low-income families. Due to this combined exposure, I came to find my passion in treating cardiometabolic and digestive disorders that are all too common, yet largely preventable. I took the opportunity to learn the broad spectrum of healthcare so I can ensure that I am able to provide my patients with the best options.
