Do Berries Have Vitamin C
Do Berries Have Vitamin C
A type of flavonoid called anthocyanin gives blueberries many of their health benefits. Flavonoids are plant compounds that often have a powerful antioxidant effect.
Anthocyanin is responsible for the blueberry's characteristic blue color. It also contributes to the numerous advantages of blueberries.
Consuming a variety of fruits and vegetables has long been associated with a reduced risk of many lifestyle-related health conditions.
Many studies have suggested that increasing consumption of plant foods such as blueberries decreases the risk of obesity, diabetes, heart disease, and overall mortality. Plant foods may also promote hair and skin health, increased energy, and overall lower weight.
Freezing blueberries is often discussed by experts. It is often said that the freezing process can diminish the potency of the blueberry's health benefits. One
However, this is not confirmed, and different sources take different stances on whether freezing blueberries reduces their impact on health. When in doubt, buy fresh, organic blueberries.
Although more research is needed, blueberries are strongly linked to various different elements of healthful living.
1) Maintaining healthy bones
Blueberries contain iron, phosphorous, calcium, magnesium, manganese, zinc, and vitamin K. Each of these is a component of bone. Adequate intake of these minerals and vitamins contributes to building and maintaining bone structure and strength.
Iron and zinc
Low intakes of vitamin K have been linked to a
2) Skin health
Collagen is the support system of the skin. It relies on vitamin C as an essential nutrient, and works to help prevent skin damage caused by the sun, pollution, and smoke. Vitamin C may also improve collagen's ability to smooth wrinkles and enhance overall skin texture.
One cup of blueberries provides 24 percent of the recommended daily allowance of vitamin C.
3) Lowering blood pressure
Maintaining low sodium levels is essential to keeping blood pressure at a healthful level. Blueberries are free of sodium.
They contain potassium, calcium, and magnesium. Some studies have shown that diets low in these minerals are associated with higher blood pressure. Adequate dietary intake of these minerals is
However, other studies have counteracted these findings. For example, a
4) Managing diabetes
Studies have found that people with type 1 diabetes who consume high-fiber diets have low blood glucose levels, and people with type 2 diabetes who consume the same may have improved blood sugar, lipid, and insulin levels. One cup of blueberries contributes 3.6 grams (g) of fiber.
A
Over the course of the study, 6.5 percent of the participants developed diabetes. However, the researchers found that consuming three servings per week of blueberries, grapes, raisins, apples or pears reduced the risk of type 2 diabetes by 7 percent.
5) Protecting against heart disease
The fiber, potassium, folate, vitamin C, vitamin B6, and phytonutrient content in blueberries supports heart health. The absence of cholesterol from blueberries is also beneficial to the heart. Fiber content helps to reduce the total amount of cholesterol in the blood and decrease the risk of heart disease.
Vitamin B6 and folate prevent the buildup of a compound known as homocysteine. Excessive buildup of homocysteine in the body can damage blood vessels and lead to heart problems.
According to a study from the Harvard School of Public Health and the University of East Anglia, in the United Kingdom (U.K.) regular consumption of anthocyanins can reduce the risk of heart attack by
The study found that women who consumed at least three servings of blueberries or strawberries per week showed the best results.
6) Preventing cancer
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
7) Improving mental health
Population-based studies have shown that consumption of blueberries is
Studies have also found that in addition to reducing the risk of cognitive damage, blueberries can also
8) Healthy digestion, weight loss, and feeling full
Blueberries help to prevent constipation and maintain regularity for a healthful digestive tract because of their fiber content.
Dietary fiber is also commonly recognized as an important factor in weight loss and weight management by functioning as a "bulking agent" in the digestive system. High fiber foods increase satiety, or the feeling of being full, and reduce appetite.
Feeling fuller for longer can reduce a person's overall calorie intake.
One cup of fresh blueberries

- 0 g of cholesterol
- 1.1 g of protein
- 0.49 g of fat
- 21.45 g of carbohydrate
- 3.6 g of dietary fiber
- 14.74 g of total sugars
That same one-cup serving provides:
- 24 percent of daily vitamin C
- 5 percent of daily vitamin B6
- 36 percent of daily vitamin K
Blueberries also provide:
- 9 milligrams (mg) calcium
- 0.41 mg of iron
- 114 mg of potassium
- 9 mg of magnesium
- 18 mg of phosphorus
- 1 mg of sodium
- 0.24 mg of zinc
- 9 mg of folate
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
The large quantities of bioactive compounds place blueberries high on the Aggregate Nutrient Density Index (ANDI). 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 132.
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.
Here are some quick tips on including blueberries in meal options:
- Use blueberries as fresh toppings on oatmeal, waffles, pancakes, yogurt, or cereal for an extra burst of flavor and nutrition in your breakfast.
- Whip up a quick and easy smoothie using frozen berries, low-fat milk, and yogurt.
- Mix fresh or dried blueberries into a spinach salad with walnuts and feta cheese.
- Fold blueberries into muffins and sweet breads.
- Blend them in a food processor with a little water, as part of a fresh syrup to top desserts or breakfast foods.

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.
The overall diet is more important than any single food in preventing disease and achieving good health. It is better to eat a varied diet as the key to healthful living, rather than to concentrate on individual foods.
