Hypertension and heart health are issues very close to my heart (ha ha, no pun intended). Literally EVERYONE on both sides of my family that has died of natural causes has died of either heart attack or stroke, and many of the women have died between the ages of 58-63. Needless to say, I take my heart healthy very seriously. Luckily, I have 3,000 years of Chinese Medicine on my side to help me be heart smart throughout my life.
When it comes to diet in particular, Chinese or commonly called "Oriental" medicine (OM) nutrition combines ancient wisdom with modern science. OM nutrition is a holistic approach, which aims to balance all five flavors within most meals with one or two flavors being emphasized for therapeutic purposes. OM nutrition for a hypertension emphasizes bitter flavors, sour flavors and energetically-cooling foods.
OM theory states the bitter flavor benefits the heart in moderation but an excess is harmful as it has a drying effect; for example, coffee is bitter. In moderation coffee acts as vasodilator increasing circulation but in excess it can raise blood pressure and has a diuretic effect. Modern scientific research has discovered while the human genome has 25 bitter taste receptors 12 of these are expressed in the human heart.
Foods with bitter flavors include: romaine lettuce, dandelion, arugula, rye. Foods that combine bitter with pungency include: citrus peel, radish, scallion and white pepper. In OM nutrition the pungent flavor can help disperse phlegm (e.g. plaque). Foods that combine bitter with sweet include: asparagus, celery, tomatoes, lettuce, quinoa and papaya. Lemon rind is bitter and sour; vinegar is also bitter and sour.
Bitter flavors have a yin, or cooling effect, clearing heat in the body while encouraging a descent of Qi, which aids in the draining of fluids. For example, celery contains the phytochemical phthalides which relaxes arterial wall tissues to increase blood flow and thereby reduce blood pressure. The fiber, magnesium and potassium in celery also help lower blood pressure and regulate fluid balance. Caution: according to OM, those with a lot of dryness and/or bone disease should moderate their intake of bitter flavor.
A tomato a day keeps the doctor away! The combination of lycopene, vitamin C and E, potassium and folic acid in tomatoes make it a power food for heart health. The bitter flavor of tomatoes come from the seeds; to reap the full benefit of tomatoes eat the seeds too. Heirloom tomatoes in season have the most flavor, find the tastiest tomatoes at your farmer’s market or trying growing your own.
Summer is the season of the heart according to Chinese medicine, meaning it is the season most likely to bring our hearts out of balance if we are exposed to excess heat, which can then create and/or exacerbate internal heat. During the summer OM nutrition recommends drinking and eating foods that cool the body and heart such as green tea, cucumbers, watermelon and lemon.
Chrysanthemum tea is a very popular summertime tea in Asia because it is so well known for its cooling properties; it is helpful for headaches, dizziness, high blood pressure, chest pain and also fevers. You can add chrysanthemum flowers to your morning green tea and in the evening combine it with chamomile tea for extra cooling benefits!
OM nutrition cautions against overdoing cold foods and drinks. Too much cold inhibits the digestive process. Drinking warm beverages and soups, as well as eating foods with a little pungency (chili pepper, garlic, ginger) causes the body to perspire slightly which naturally cools the body.
For those who happen to have hypertension plus a lot of dryness: dry skin, dry eyes, dry mouth and thirst, constipation and even hormonal deficiencies can benefit from increasing their healthy fat intake. Many nutrients are fat soluble, the body uses cholesterol to make hormones, bile and vitamin D. Healthy fats nourish yin in OM nutrition theory. Some Americans who suffer from hypertension are also thin with an underlying yin deficiency, such as those with the onset of hypertension that coincides with menopausal symptoms. Sources of healthy fats include: nuts, seeds, avocado, olive oil, flaxseed oil and fish.
Eating beans, peas and grains are high in potassium, magnesium, fiber and are high in choline which is vital in lowering hypertension and boosting fat metabolism. Whole grains are also a good source of niacin and vitamin E and are recommended for healthy arteries, especially those that are slightly bitter such as: rye, quinoa, amaranth and oats.
