Yes, sourdough bread can be good for high blood pressure, especially whole-grain versions, because its fermentation process creates compounds that may help lower blood pressure, and it often contains less salt than regular bread, while fiber in whole grains further supports heart health, but check labels for sodium, as it can vary. Some studies suggest sourdough contains peptides that block ACE (like some medications) and GABA, potentially relaxing blood vessels, and improved mineral absorption aids cardiovascular function, though effects are generally modest.
If you're worried maintaining lowered blood pressure might mean giving up bread, you will be thrilled to know that whole grain breads made out of whole wheat, whole rye or whole multigrain have shown to have a blood pressure lowering effect if eaten regularly.
Lifestyle habits can increase the risk of high blood pressure, including if you:
Baked Chicken Sandwich Instead of Cold Cut Sandwich
For a bonus, a sandwich on whole-grain bread with low-fat cheese and mustard, instead of white bread with mayo or butter, can eliminate empty calories and increase adherence to DASH.
Whole-grain breads are good sources of nutrients that help maintain a healthy immune system. They also provide dietary fiber that can help improve cholesterol levels and lower the risk of heart disease, stroke, obesity and Type 2 diabetes.
Cardiologists generally advise avoiding processed meats, sugary drinks and sweets, and foods high in trans fats and sodium, like most fried foods and salty snacks, because they raise bad cholesterol, blood pressure, and inflammation, significantly increasing heart disease risk. Focusing on whole foods and limiting these culprits is key for heart health.
The healthiest sourdough bread is typically a whole-grain or dark rye sourdough, made with minimal ingredients, featuring high fiber, protein, and nutrients, which helps control blood sugar and increases fullness compared to white sourdough. Look for loaves with whole wheat, spelt, or rye flours, fewer additives like sugar, and consider adding seeds for extra benefits, as traditional whole-grain sourdough offers superior gut health and nutritional advantages.
Eat this: vegetables, fruits, whole grains, fat-free or low-fat dairy, fish, poultry, beans, nuts and seeds, vegetable oils. Limit this: fatty meats, full-fat dairy, sugar sweetened beverages, sweets, sodium intake.
What are the Best Meals for High Blood Pressure? The best meals for high blood pressure prioritize whole grains, lean proteins (think legumes, fish, soy, and chicken breast), vegetables, fruit, and low-fat dairy.
Try these lifestyle canges as natrual ways to lower blood pressure.
For those who have hypertension, regular physical activity can bring blood pressure down to safer levels. Some examples of aerobic exercise that can help lower blood pressure include walking, jogging, cycling, swimming and dancing. Another helpful type of exercise is high-intensity interval training.
Eating too much sodium—an element in table salt—increases blood pressure. Most of the sodium we eat comes from processed and restaurant foods. Not eating enough potassium—a mineral that your body needs to work properly—also can increase blood pressure.
Pizza. Just one slice of cheese and pepperoni pizza can contain more than half of your daily recommended dietary sodium. Heck, even if you go for the veggie version, you're still knocking your blood pressure.
Bread available in bakers or supermarkets can contain large amounts of salt which will raise your blood pressure. The amounts vary, so check the labels and compare options, and choose brown or wholemeal breads instead of white. You can also make your own bread without any salt.
Sourdough bread, when made with whole grain, can contribute to heart health. The fiber content can help lower cholesterol levels and support healthy blood pressure. Additionally, the improved mineral absorption from the fermentation process supports cardiovascular function.
For better blood pressure control, brown rice is better than white rice in part because brown rice is a significantly better source of minerals like potassium and magnesium. Many studies have found that foods rich in these minerals help blunt some of the toxic effects of salty foods.
Walking lowers systolic blood pressure by 4.11 mm Hg (95% CI, 3.01 to 5.22 mm Hg). It lowers diastolic blood pressure by 1.79 mm Hg (95% CI, 1.07 to 2.51 mm Hg) and resting heart rate by 2.76 beats per minute (bpm; 95% CI, 0.95 to 4.57 bpm).
Beetroot juice can be a concentrated source of nitrates and it's thought that one of their effects is to lower blood pressure. However, you can also find nitrates in other fruits and vegetables too including spinach, celery, kale, bananas and strawberries.
At the beginning, measure your blood pressure at least twice daily. Take it first in the morning before eating or taking any medicine. Take it again in the evening. Each time you measure, take two or three readings to make sure your results are the same.
The less you sleep, the higher your blood pressure may go. People who sleep six hours or less may have steeper increases in blood pressure. If you already have high blood pressure, not sleeping well may make your blood pressure worse.
Sourdough's disadvantages include still containing gluten (not safe for celiac disease), potential for high sodium in commercial versions, moderate carbs/calories, and possible digestive issues for some due to fructans or yeast/bacteria, despite fermentation making it often easier to digest than regular bread; it's not inherently low-carb or fiber-rich unless made with whole grains.
The best supermarket sourdough depends on preference, but top contenders often cited for quality, taste, and value include Wildfarmed White Sourdough (UK's overall top pick for regen farming), Aldi's Wild Rise Sourdough (great value), La Brea Bakery (US winner with good chew/flavor), and Costco's Kirkland Signature (large, bakery-like loaf). For Australian options, Coles Finest and Woolworths Crafted lines are popular, with Edwards Sourdough noted for its long fermentation and pure ingredients.
Avocado Bites:
Simply top your gluten-free sourdough with avocado slices for a filling snack. You can sprinkle a little salt and pepper, or even a dab of sugar if you have a sweet tooth, for added flavor. Pair with a fruit for a balanced snack.
