What to eat to lower blood pressure
Here are some great foods and drinks ideas that one of our Registered Dietitian, Jong Min Lee, recommends for people with high blood pressure. Scroll down to the end to find out the easy homemade recipes!
1. Foods: More Potassium, Less Sodium
It is widely known that consuming more sodium leads to a rise in blood pressure. But did you know that consuming more potassium has been shown to decrease blood pressure? The modern western diet, which we are accustomed to, is rich in processed foods and dietary sodium, but low in potassium, which means a decreased potassium-to-sodium ratio. The ratio is important because these two specific electrolytes are essential to our bodies and are meant to interplay with each other, allowing for physiological balance (known as homeostasis).
A higher intake of potassium has been shown to decrease blood pressure. [1, 2]
Americans ages 20 and over consume 3.016g (men) and 2.320mg (women) on average of potassium per day. 
The DASH diet (Dietary Approaches to Stop Hypertension) recommends a daily intake of 4.7g of potassium for healthy adults.
Foods such as fruits and vegetables, dairy, legumes, meats, poultry, and fish are rich in potassium. Whole wheat and whole grains possess higher amounts of potassium than their white counterparts.
Potassium rich foods include (1 g = 1000 mg):
Dried apricots (1900mg), dark chocolate (830mg), dates (696mg), salmon (628mg), white beans (561mg), spinach (558mg), baked potato with skin (535mg), cod (516mg), avocado (485mg), pork chop (449mg), Brussels sprouts (389mg), bananas (358mg), low-fat yogurt (234mg), orange juice (200mg), and low-fat milk (154mg) 
A sample meal of spinach salad (558mg) with a half avocado (485mg), grilled salmon (628mg), and half of a medium baked potato with skin (535mg) would include 2206mg of potassium (excluding the consideration of dressing or the way it is cooked—preferably this meal should be cooked with minimal salt). This meal would provide 47% of the recommended daily potassium intake.
On the other hand, excessive sodium consumption can lead to cardiovascular diseases by causing water retention, which leads to an increase in blood volume, thus applying more pressure on our blood vessels.
Americans consume more than 3400mg of sodium on average per day.
According to the 2020-2025 Dietary Guidelines of Americans, it is recommended to consume less than 2300mg of sodium per day, that is, 1 teaspoon of table salt.
While sodium can be found naturally in foods, many processed foods add and by adding salt during process (per 100g) 
The following foods are included with their amount of sodium (1 g = 1000 mg): Fruits, vegetables, oils, and cereals: ~20mg, with few exceptions Meat and fishery products: 40-120mg Whole milk: ~50mg Some shellfish, such as mussels and oysters: 500mg Frozen foods: ~700mg 1 tablespoon of soy sauce: ~900mg Bread: ~1500-2000mg Meats and cheeses: ~2500mg
2. Meals: More home cooked, less prepared and processed
The truth behind prepared and processed meals
Nowadays, more and more people purchase prepared meals and eat out instead of cooking meals at home. But when we eat out, we do not know what ingredients are being used, which means we are not aware of the sodium and fat content we are consuming. How much salt was utilized to produce that yummy flavor? How much butter did they use? What type of oil did they use to cook? Learning to cook in a simple, healthy way will help us to be healthier while also making us feel better.
Benefits of eating home-cooked meals:
Better diet quality (e.g. more fruits and vegetable consumption => less sodium and fat content) 
Normalizing of BMI and body fat. 
A positive influence on self-esteem, quality of life, and socialization. 
👉Doctorhere’s food experiment: LASAGNA

Nutrition comparison (1 serving)
As this food comparison demonstrates, the homemade lasagna contained more fiber, protein, and potassium, and less sodium.
3. Drink more tea and water
Drinking tea on a regular basis is known to help lower blood pressure. A high flavonoids content in black tea (that is fermented) and catechins in green tea are contributors to lowering blood pressure. A meta-analysis study has supported that drinking black or green tea showed a significant reduction in systolic blood pressure (-2.36mmHg on average) and diastolic blood pressure (-1.77mmHg on average). The teas, taken one to three times daily, were consumed in beverage form as well as capsule form and powder packets. 
Bioactive compounds such as polyphenols, carotenoids, ascorbic acid, and tannins of hibiscus (so called “sour tea”) provide anti-inflammatory properties, which leads to a reduction in blood pressure. A meta-analysis study demonstrated that when taken one to three times daily in tea or capsule form, hibiscus tea consumption significantly reduced systolic blood pressure (-7.10mmHg on average). 
According to the FDA, 400mg of caffeine a day is generally safe for the general population. However, some variation exists in regards to caffeine sensitivity and metabolism.
1 (8 ounce) cup of black tea or green tea contains 30-50mg of caffeine, while 1 cup of coffee contains 80-100mg caffeine.
Our body is made up of more than 60% water. Water plays a role in helping all of our body organs function properly. When our body lacks water, we may suffer various symptoms such as fatigue and dizziness.
So how much water should we drink? Our necessary water intake may vary depending on many factors such as physical activity, season, metabolism, weight, age, and gender. But according to the Academy of Nutrition and Dietetics, men should drink about 12.5 cups or 3 liters, and women should drink 9 cups, or 2 liters per day. 
How can we make sure that we drink enough water? First of all, when we wake up in the morning, it’s good to have 1 cup of water to wake up your body. Also, carry a water bottle with you throughout the day, filling it up regularly as you drink. When eating out, choose water (tap, still, or sparkling) instead of other drinks. If you want a little bit of flavor, just ask for water with lemon slices. And if you want more flavor at home, you can experiment with different options, such as lemon, lime, cucumber, basil, and mint.
In summary, eating more potassium-rich foods and less sodium-loaded foods; eating more home cooked meals and less prepared and processed meals; and drinking more tea and water helps naturally lower your blood pressure. However, everyone’s lifestyle and preferences are different, and each of these steps is easier said than done.
