You could boost your memory
โMemory has been touted with blueberries,โ says registered dietitian nutritionist Caroline Passerrello, MS, RDN, LDN. One long-term study of 16,010 adults age 70 or younger found that those who ate more blueberries and strawberries delayed age-related cognitive decline by up to 2.5 years. The researchers guess that antioxidants called anthocyanins in blueberries could be behind the effects. Other studies have found that large doses of resveratrol could slow the progress of Alzheimerโs disease.
Youโll fight wrinkles
A cup of blueberries packs in nearly a quarter of your daily needs for vitamin C, which can help your body build and maintain collagen, a protein that gives your skin firmness. โThe more collagen you have, the less likely you are to have wrinkles,โ says Passerrello. Women who get more vitamin C are less likely to have wrinkled skin, found a study of 4,025 middle-aged women in the American Journal of Clinical Nutrition. Don’t miss these other foods that fight wrinkles.
Youโll boost your immune system
When you have inflammation in your body, itโs harder to kick a disease. โYour defense system and immune system is taking time tending to where the inflammation is coming from,โ says registered dietitian nutritionist Marjorie Nolan Cohn, MS, RDN, spokesperson for the Academy of Nutrition and Dietetics. Blueberries are famously high in antioxidants, which can help keep inflammation levels down. In particular, their high levels of vitamin C can give your immune system a boost, says Passerrello.
You could prevent cancer
An antioxidant-rich diet could also help your body fight cancer. If your body is too busy fighting inflammation, it might not notice DNA mutations that lead to cancer. โOur DNA is always replicating and tripping up that process, but our body is really good at catching it,โ says Nolan Cohn. โWhen our body misses it, that messed-up DNA goes on to replicate itself.โ Studies have linked pterostilbene, an antioxidant in blueberries, to protection against esophagus, pancreas, and colon cancers.

Youโll snack less before lunch
A cup of blueberries has between three and four grams of fiber, which helps you feel more satisfied with just 85 calories. โTheyโre really low in calories for the fiber content,โ says Nolan Cohn. โYou get more bang for your buck.โ Even though theyโre low-calorie, theyโre also sweet, so you could get away with eating a less sugary cereal with flavor boost from berries.

You could control diabetes
Diabetics could benefit from having that fiber from blueberries at breakfast. โStudies show unequivocally that higher fiber diets help control blood sugar and blood glucose, and help stabilize insulin levels,โ says Nolan Cohn. If you use the American Diabetic Associationโs exchange diet, blueberries also give you a bigger serving of fruit than youโd get from, say, fruit cocktail, so youโll get in a bigger, more satisfying portion, says Passerrello. Avoid these bad eating habits for diabetes.
You could protect your heart
The benefits of fiber donโt end thereโstudies have shown it can also lower โbadโ LDL cholesterol and increase โgoodโ HDL. Plus, blueberries contain potassium, an electrolyte that helps your heartโs electrical system, and are packed with antioxidants. โBlueberries contain antioxidants, and these have been shown to be cardioprotective,โ says Passerrello. A 16-year study found linked diets rich in anthocyaninsโlike in blueberriesโto a lower risk of death from coronary heart disease. Beware of these foods that are bad for your heart.
Your bones will stay strong
Blueberries contain a quarter of your daily needs for manganese, a mineral that plays a key role in healthy bones by shuttling nutrients around your body. โIt helps the body process the foods and use nutrients correctly to help bone development,โ says Passerrello. Blueberries also contain some calcium and magnesium. You likely already know that calcium builds strong bones, but magnesium helps deliver that calcium to the bone so it can do its job, says Nolan Cohn. (Find out magnesium is the key to better fitness.)
