When it comes to focus and memory, there is no denying the importance of brain health. While several factors influence cognitive function, the foods we eat on a daily basis are a crucial part of keeping our mind sharp. There are many nutrients that can help support brain health-one that is found in fruits and vegetables is anthocyanins. Compared to other commonly consumed fruits, berries are uniquely high in anthocyanins, plant compounds that are responsible for their vibrant blue, red, and purple color. In fact, research shows that anthocyanins present in blueberries (163.3 mg/100 g) may help to improve mild cognitive performance in older adults.

One Serving, or a Cup of Blueberries:

  1. Is considered one serving of fruit
  2. Contain just 80 calories and is a good source of fiber
  3. Contributes essential nutrients including Vitamin C, Vitamin K, Manganese, and Phytonutrients called Polyphenols
  4. Contains Anthocyanins, which are compounds that give blueberries in their blue color
  5. Is a good source of Fiber, containing ~4g

Many studies have suggested that increasing consumption of plant foods such as blueberries decreases the risk of obesity, diabetes, heart disease and overall mortality. Although more research is needed, blueberries are strongly linked to various different elements of healthful living.

  1. Maintaining Healthy Bones: Blueberries contain iron, phosphorus, 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.
  1. Skin Health: One cup of blueberries provides 24 percent of the recommended daily allowance of vitamin C. Vitamin C is 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.
  1. 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 One cup of blueberries contributes 3.6 grams (g) of fiber.
  1. 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.
  1. 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.
  1. Improving Mental Health: Population-based studies have shown that consumption of blueberries is connected to slower cognitive decline. Studies have also found that in addition to reducing the risk of cognitive damage, blueberries can also improve a person’s short-term memory and motor coordination.
  1. ­­­­­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.
