Excessive buildup of homocysteine in the body can damage blood vessels and lead to heart problems. The study found that women who consumed at least three servings of blueberries or strawberries per week showed the best results. Vitamin C, vitamin A, and the various phytonutrients in blueberries function as powerful antioxidants that may help protect cells against damage from disease-linked free radicals.
Research suggests that antioxidants may inhibit tumor growth, decrease inflammation in the body, and help ward off or slow down esophageal, lung, mouth, pharynx, endometrial, pancreatic, prostate, and colon cancers. Blueberries also contain folate, which plays a role in DNA synthesis and repair.
This can prevent the formation of cancer cells due to mutations in the DNA. Population-based studies have shown that consumption of blueberries is connected to slower cognitive decline in older women. Blueberries help to prevent constipation and maintain regularity for a healthful digestive tract because of their fiber content. High fiber foods increase satiety, or the feeling of being full, and reduce appetite. One cup of fresh blueberries contains :. Blueberries also contain copper , beta-carotene , folate, choline, vitamins A and E, and manganese.
As well as anthocyanins, vitamins, and minerals, blueberries contain a diverse range of phenolic compounds such as quercetin, kaempferol, myricetin, and chlorogenic acid.
These contribute to the antioxidant capacity of blueberries. This index rates foods based on their vitamin and mineral content, phytochemical composition, and antioxidant capacity. Foods with the most nutrients per calorie have the highest rankings, and blueberries are placed among the top fruits and vegetables for nutrient density, with an ANDI score of ANDI is one of several rating systems for food nutrition , but further research is needed to determine the role of specific foods in disease prevention.
Blueberries are available fresh, frozen, freeze dried, and in jellies, syrups, and jams. Be sure to check the label of frozen and dried blueberries for added sugars. When selecting jellies or jams, choose all-fruit spreads without added sweeteners, juices, or fillers. People who are taking blood-thinners, such as warfarin, must not suddenly change their intake of blueberries or other sources of vitamin K.
Vitamin K plays a key role in blood clotting, and it could affect the blood-thinning action of the drug. In this blog post, we explain the typical colors of the blueberry flesh and explain why this color varies.
In fact, there are over 30 varieties of blueberries! The ones typically sold in supermarkets are cultivated blueberries also known as the highbush blueberries that grow in different parts of the world. Studies have shown that the amount of antioxidants in blueberries is affected by several factors such as the cultivation method, composition of the soil, use of pesticides and fertilizers, and genetic diversity.
On the other hand, a variety of lowbush blueberries have a dark blue or purple inside out. These blueberries are grown wild in Northern European forests and are also known as bilberries.
The inside color of wild blueberries is as dark as their skin and is so intense that just a few berries can give a beautiful color to your desserts, smoothies, pastries, or teeth. If interested, you can read more about the differences between wild bilberries and cultivated blueberries.
Blueberries have high amounts of anthocyanins, a group of powerful and extremely beneficial antioxidants for human health. The unique summer conditions of the Arctic Circle, where the sun is up during the night, make wild Nordic blueberries unique both in color and in the concentration of anthocyanins they have.
