Your blood pressure fluctuates naturally throughout the day. Everything you eat, do and think can potentially impact these numbers. If diagnosed with high blood pressure, lifestyle changes, including a low-fat diet and exercise, are encouraged for long-term health. However, those wishing to start dropping their numbers immediately might be able to lower their blood pressure in an hour with certain foods and water. Knowing about your food choices and how they impact your blood pressure will help you make long-term healthy choices.
Eat natural diuretic foods, such as watermelon and cranberries, unless contraindicated by your healthy history or prescription medications. For the average healthy adult, these foods produce a fluid-flushing effect during digestion. Decreasing the extra fluids in your tissues will reduce the workload on your heart and decrease your blood pressure.
Drink plenty of water and avoid caffeinated, sugary or alcoholic beverages. Although excess fluids in the tissues can add to high blood pressure, having well-hydrated veins and arteries will ease the heart's workload. Both caffeine and alcohol can dramatically raise blood pressure in some people. Sugary drinks, such as soda, might increase your blood pressure during digestion.
Eat plenty of fresh, raw fruits and vegetables. These nutritious natural foods are full of vitamins, minerals and fiber that might lower your blood pressure during digestion. The minerals, such as potassium and calcium, in these foods play a pivotal role in blood pressure regulation. Consider a salad containing tomatoes, spinach, garlic and celery -- all of which can help decrease your blood pressure.
Avoid salty foods such as canned goods, prepackaged meals or processed foods. These foods usually are found in the snack and convenience aisles of supermarkets and can contain large amounts of sodium, which can rapidly increase your blood pressure. Especially for African Americans and the elderly, avoiding salty foods and snacks can decrease your numbers.
