Our heart is our body’s engine, it’s what keeps the blood circulating so it can transport all the nutrients that our different body parts depend on, and so that it can remove all the waste. Caring for our heart should be a top priority for all of us. Sadly, heart disease is the number one cause of death in the world.

The good news is that a large amount of these deaths is preventable through a healthy diet. The sad news is that most people are still following the Standard American Diet (SAD) which is packed with saturated fat, cholesterol, and toxins. Most children are already developing heart disease, it just won’t manifest until they’re older. Fad diets promoting animal-based products while antagonizing healthy carbs are worsening this situation.

Below, we talk about how our heart works, the nutrients that support it, and some of their top plant-based sources. We also share important facts that can help you take great care of your heart and your family’s precious hearts.

Important Things to Know for Our Heart Health

Check out the interesting facts below! Tap on the red triangles to flip the tiles and learn more details.

Most Americans who die suddenly of heart disease, don’t get a warning.

It’s called sudden cardiac death, and it means that death happens within the hour of symptom onset. More than 360,000 people suffer a cardiac arrest outside of the hospital every year in the US. 60% to 80% die before making it to the hospital.

High LDL Cholesterol levels is the number one risk for heart disease.

The optimal LDL cholesterol level is between 50 and 70 mg/dL, this means a total cholesterol of  under 150 mg/dL. The famous China Study revealed that levels of Total Cholesterol in China were 127 mg/dL, yet being under 200 mg/dL is considered normal by most doctors in the U.S. Achieving the recommended level of under 150 mg/dL is easy for most people when following a WFPB diet.

Dietary choices lead to heart disease starting in childhood, or even before birth.

Nearly all American children who die after an accident by the age of 10 and get an autopsy are found to be in the first stage of atherosclerosis (fatty streaks in our arteries). This is very alarming! What’s more alarming is that newborn babies whose mothers had high LDL cholesterol levels, also presented early stages of heart disease. By the time most Americans are 20 to 30 years old, they already have plaque. Fortunately, this can be reversed when switching to a WFPB diet.

Coconut oil should be avoided together with other sources of saturated fat.

Coconut oil is high in saturated fat and it significantly raises total, LDL and HDL cholesterol levels, raising risk factors for heart disease. Studies also found no benefit of consuming coconut oil for inflammation, blood sugar control, or weight.

But, isn’t Omega 3 supposed to be good for our heart? Turns out, it’s not!

The notion that Omega-3 fatty acids supported cardiovascular health turned out to be based on biased studies and has now been debunked by more recent and extensive studies. These studies show no effect of Omega 3 in cardiovascular health. However, Omega-3 fatty acids do support our brain health. If you choose to supplement your DHA and EPA, be sure to use a plant-based option (from algae). You can also get plenty of ALA from seeds, legumes, greens, and walnuts. Fish sources are highly contaminated.

High levels of magnesium are associated with 40% reduced risk of sudden cardiac arrest.

Top sources of magnesium include dark leafy greens, nuts, seeds, legumes, and whole grains. So, it’s easy to get plenty when following a balanced, whole-foods, plant-based diet. Unfortunately, most Americans are not even getting the Daily Value of 420 mg. The average intake is 300 mg.

3 reasons eating meat hurts our heart: saturated fat, endotoxins, and heme iron.

A study showed that people eating at least one serving of meat a day had a 22% higher risk of heart disease.

  • Saturated fat raises LDL cholesterol levels, which increases heart disease risk
  • Endotoxins are bacteria found in raw, cooked and fermented animal products, that lead to artery inflammation
  • Heme iron found in meat was found to increase heart disease by 57% while non-heme iron found in vegetables show no relationship to risk of mortality from heart disease

Excessive sodium leads to high blood pressure, also known as the “silent killer.”

About 90% of adults in the U.S. are expected to develop high blood pressure in their lifetimes. Excess sodium pulls water into our blood vessels, thus increasing our amount of blood. The more blood flows inside these vessels, the more pressure they get. Eventually, our blood vessel walls get injured, resulting in faster buildup of plaque.

Plants have all the sodium we need, so the ideal practice is to omit completely. However, most of the sodium we get doesn’t even come from the salt in home-cooked meals. About 70% comes from processed foods and restaurant foods.

Even moderate exercise can reduce our risk of heart disease by 50%.

The more we exercise, the better, but even a 20-30 minute walk every day will improve our odds over having a sedentary life. So, take those stairs instead of the elevator. Walk to the mailbox instead of driving. Or start a habit of going out on walks every day. This also helps with stress management, another risk factor for heart disease. Stress makes plaque build up faster in our arteries. It also makes the arteries constrict and our blood clots faster, leading to a heart attack of stroke.

In Loving Memory

A man with a black jacket and purple collar.

Steve Walsh was an amazing father and human being who lived life with compassion, unconditional love, a strong dedication to justice, and a great sense of humor. He died from sudden cardiac arrest at the early age of 62. This page is dedicated to him, hoping that the information we provide helps other families prevent this tragic loss.
