In addition, blueberries are a good fiber source, which can help reduce cholesterol levels.

Cranberries and Their Antioxidant Properties

One of the main types of antioxidants present in red blueberries are flavonoids. Flavonoids are a group of plant compounds very studied for their possible health benefits. They act neutralizing free radicals and have been related to a lower risk of chronic diseases, such as heart disease and certain types of cancer.

Tip: Including blueberries in the diet can help increase the intake of flavonoids and other antioxidants, favoring health and general wel l-being.

• Red blueberries are especially rich in a flavonoid called Quercetin, which has shown to have ant i-inflammatory and antiviral properties.
• Another flavonoid present in blueberries, known as Miricetina, has demonstrated its potential to inhibit the growth of cancer cells and reduce the risk of certain types of cancer.
• In addition, red blueberries contain proantocyanidins, another kind of flavonoids that have been associated with a lower risk of urinary tract infections (IU) by preventing bacteria from adhere to the walls of the urinary tract.

1. Studies have suggested that regular consumption of red blueberries or derivative products can be beneficial to prevent ITUs, especially in susceptible people, such as women and the elderly.
2. The high antioxidant capacity of red blueberries can also have a positive impact on heart health by reducing oxidation of LDL cholesterol, one of the main risk factors for cardiovascular diseases.

Cranberries and Their Potential Role in Preventing Urinary Tract Infections

Bacterial adhesion prevention

One of the key mechanisms by which blueberries can help prevent ITU is the prevention of bacterial adhesion. Bacteria such as Escherichia Coli (E. coli) are the most common cause of ITIs and are able to adhere to urinary tract cells, causing infection. However, it has been shown that certain compounds present in red blueberries, such as proanthocyanidins, inhibit the accession of these bacteria, making it difficult to cause an infection.

Reduction of the recurrence rate

Urinary infections have a high recurrence rate, since between 20% and 30% of women suffer several infections within one year. Research suggests that the consumption of red blueberry products can help reduce the recurrence of ITU. In a randomized controlled trial, women who consumed concentrated red blueberry juice experienced a 20% reduction in ITU recurrence compared to those who received a placebo. The mechanism of this reduction is not yet known exactly, but it is believed that it is related to the antimicrobial properties of red blueberries.

Incorporate blueberries into the diet

• The consumption of entire red blueberries (fresh or dry) is the most beneficial, since they retain their natural compounds.
• Taking blueberry blueberry juice can also be a good option, but it is important to keep in mind that commercial blueberry juices usually contain added sugars, which can be harmful to health.
• For those who prefer a more comfortable option, there are red blueberry supplements in the form of capsules or tablets. However, it is essential to choose high quality supplements from accredited sources.
