Pineapple
Pineapples are an excellent source of vitamins A, B3, B5, B6, and C, copper, iron, potassium, zinc, choline, folate, and beta-carotene (21). These sweet and juicy tropical fruits help increase the permeability of the blood vessel walls to oxygen and other nutrients. The active component of pineapple, bromelain, also helps reduce inflammation and prevents blood clot formation (22).
Consume a cup of pineapple as is, or add it to smoothies, juices, and salads.
Berries
Blueberries, strawberries, and raspberries are great sources of vitamins A, B3, B5, B6, and C, iron, potassium, copper, zinc, choline, folate, and antioxidants (23), (24), (25). Berries also help reduce inflammation and lipoprotein-cholesterol levels and improve insulin sensitivity (26).
Consume a cup of organic or locally grown mixed berries every day. Include them in fruit bowls, smoothies, and juices.
Figs And Dates
Dried figs and dates are loaded with iron, copper, potassium, vitamins A, B3, B5, and folate (27), (28). These nutrients help boost immunity and improve cognitive abilities. Dates and figs are rich in polyphenols with antioxidant properties and help reduce free radical damage and oxidative stress to prevent neurodegeneration and provide therapeutic effects (29), (30).
Consume 1-2 medjool dates and a couple of dried figs with smoothies. People with diabetes must consult their doctor before consuming dried figs and dates as they have high sugar content.
Citrus Fruits
Citrus fruits are rich in vitamin C, an antioxidant that helps develop hemoglobin-based oxygen carriers (HBOCs). Several secondary metabolites, such as alkaloids, coumarins, phenol acids, flavonoids, limonoids, and carotenoids, present in citrus fruits are also highly beneficial for human health. They have anti-inflammatory, and antioxidant properties, and help maintain your cardiovascular health, prevent nerve cell damage, and expand your blood vessels to improve blood flow (31).
Include limes, lemons, tangerines, oranges, and grapefruits in your diet. You can juice them or add them to salads.
Avocados
Avocados are rich in vitamins A, B3, B6, B12, choline, folate, polyunsaturated fatty acids (PUFAs), and dietary fiber. These nutrients help boost oxygen levels, reduce cholesterol, promote a healthy heart, control blood sugar levels, improve lipid profile, protect DNA, prevent osteoarthritis, improve eye health, and help in weight management (10).
Consume half an avocado every day in smoothies, salads, or delicious tacos to give your oxygen levels a boost and improve your overall health.
Pomegranate
Pomegranates contain iron, copper, zinc, vitamins B3 and B6, and choline (11). They improve blood flow by increasing nitric oxide bioavailability and boost oxygen delivery (12). Consuming pomegranate kernels or freshly pressed pomegranate juice helps dilate the blood vessels, enabling improved blood flow (13). This reduces the risk of tissue damage due to low oxygen saturation.
Consume a cup of pomegranate kernels, drink 375 ml of pomegranate juice per day, or add it to salads and include this oxygen saturation-improving alkaline food in your diet.
Kiwi
This sweet ‘n sour juicy tropical fruit is a good source of dietary fiber, copper, iron, vitamins A, B3, B5, B6, and C, choline, and several antioxidants. Kiwifruit helps prevent DNA damage, boosts the immune system, reduces the severity and duration of upper respiratory infections in the elderly, and lowers inflammation (14).
Consume a large kiwi per day. You can also add it to smoothies, juices, and salads to increase the consumption of vitamins and minerals that help increase oxygen saturation in the blood.
Cantaloupe
Cantaloupe is a great source of vitamins A, B3, B5, B6, C, choline, folate, iron, and antioxidants (15). This fruit is low in sugar and can be consumed by people with high blood sugar levels. It also has anti-inflammatory and immunity-boosting properties (16).
