Long before the ancient Greek surgeon Galen carried out meticulous dissections of the heart, the Egyptians wrote about health and disease in relation to how the heart “speaks in vessels” with the rest of the body. Today, physicians may not associate the heart with the soul (or soul mates), but many credit early Egyptian medical knowledge of the heart as a precursor to modern cardiology.
The Heart: Powerful, but Vulnerable
A key element of a healthy body is a healthy heart. The heart is the center of our cardiovascular system and beats an average of 100,000 times per day supplying oxygen rich blood to the whole body. Every day we make choices that have a profound affect on the health of this vital organ. Most heart disease (HD) is linked to inflammatory risk factors such as lack of exercise, obesity, smoking, stress, and poor eating habits.
One major condition that can develop with these risk factors is Hypertension, also known as high blood pressure. Often called the ‘silent killer’, Hypertension can cause significant damage throughout the cardiovascular and other body systems and ultimately results in over 80 million deaths each year.
The Silent Killer
Blood pressure is the amount of pressure exerted on the inside of blood vessels as the heart pumps the blood through the body. When there is resistance in the vessels, the pressure rises and hypertension results. The longer hypertension goes undetected and/or uncontrolled, the greater the damage to blood vessels and other organs. Hypertension can lead to heart attack, stroke, ruptured blood vessels, kidney disease or failure, and heart failure.
Warning signs for high blood pressure are rare but can include headaches, blurred vision, light-headedness, shortness of breath and nosebleeds. However, there are typically no warning signs or symptoms for hypertension, which is why it is called the silent killer.
Hypertension is diagnosed by looking at 2 numbers in your BP reading: Systolic pressure (the top number) is the pressure in your arteries when the heart beats (contracts). Diastolic pressure (bottom number) represents the pressure in your arteries between beats.
• Normal blood pressure is below 120/80
• Prehypertension is 120 – 139 systolic or 80 – 89 diastolic.
• Hypertension is 140/90 or higher
The Potassium Secret for a Healthy Heart
You’ve no doubt heard the best thing to do when you have hypertension is to reduce the amount of salt/sodium in your diet. Did you know the average adult needs 4,700 mg of potassium daily compared to only 200 mg of sodium. Unfortunately for most of us, our eating habits give us way too much sodium – 3,300 mg a day – and not nearly enough potassium. This imbalance can increase your risk of developing hypertension.
What’s truly important for your heart, and a more accurate strategy to prevent high blood pressure, is to balance the relationship between potassium and sodium (salt) in your daily diet. Proper sodium-potassium balance is necessary for nerve transmission, muscle contraction, fluid balance, and the optimal health of all the cells in your body. In regard to the heart, potassium is particularly important for regulating heart rhythm and maintaining blood pressure.
By reducing your sodium intake, you are often correcting the sodium-potassium imbalance without realizing it. To further support your heart health, eat more potassium-rich foods such as sweet potato, spinach, banana, peas, legumes, apricots, avocados, halibut and molasses.
More Healthy Heart Tips & Heart-Healthy Diet Do’s:
- Eat a variety of fresh fruits and dark green veggies daily.
- Use plant-based oils for cooking.
- Eat mindfully, not on-the-run.
- Reduce or eliminate packaged foods, sugar, and red meat.
- Walk, No Need to Run: 30 minutes of daily, brisk walking lowers your risk for hypertension.
- Be Calm: Learn to manage stress with healthy coping techniques, such as, deep breathing, yoga, meditation, gratitude journaling, and getting quality sleep.
- Supplemental Support: Nutritional supplements shown to support heart health include Hawthorn, CoQ10, Essential Fatty Acids (Omega 3), Magnesium, Garlic and B-vitamins. Always speak with your Integrative/ Functional Medicine physician as to which forms of these supplements and what doses are optimal for you as all forms are not equal in efficacy or quality. Supplements you might have heard about—Natto-K (nattokinase), Guggul, or Niacin—should not be taken without the supervision of your health practitioner.
Because some blood pressure medications affect the potassium level in the body, be sure and discuss the best strategy for making this adjustment with your Functional Medicine Physician /Integrative Holistic Doctor.
