Anthocyanins in fruits -
This has been demonstrated in both in vitro and in vivo research trials in humans and animals. Studies show that anthocyanins have the ability to naturally fight cancer by blocking cell proliferation and inhibiting tumor formation by interfering with the process of carcinogenesis.
One way anthocyanins inhibit tumorigenesis is by blocking activation of mitogen-activated protein kinase pathways. Studies have found that diets high in antioxidants like anthocyanin lead to reversal in certain age-related deficits that affect neural and behavioral parameters, including memory and motor functions.
Anthocyanins have been credited with protecting memory, coordination and neural function in older populations. One study out of Korea found that administration of isolated anthocyanins from purple sweet potato enhanced cognitive performance and inhibited lipid peroxidation in brain tissues in mice.
Antioxidants seem to improve physical performance by lowering exhaustion and the negative effects of excessive oxygen and radical accumulation during physical activities. In one double-blinded clinical trial that involved 54 female and male athletes, when one group was given milligrams of anthocyanin pills per day for six weeks, the participants in that group were found to experience a significant improvement in their VO2 max maximal oxygen consumption compared to the second group that received milligrams of placebo pills daily.
Some studies have also found that fruit juices that contain anthocyanin, such as percent tart cherry and blueberry juices, have antioxidant and anti-inflammatory effects that wind up positively influencing muscle damage following exercise and the ability to properly recover.
Anthocyanin has been shown to help enhance night vision and overall vision by protecting the eyes from free radical damage. One study found that oral intake of anthocyanosides from black currants resulted in significantly improved night vision in adults. Research suggests that enhancement of rhodopsin regeneration and protection against inflammation are at least two mechanism by which anthocyanins improve sight and protect the eyes.
In addition, some of the conditions that research suggests anthocyanins may help prevent include:. Is taking anthocyanin supplements as beneficial as eating anthocyanin foods?
As of now, experts recommend getting anthocyains from food sources rather than in isolated supplement form. That being said, one review of 10 studies involving use of anthocyanin supplements found that supplementation significantly improved LDL cholesterol among diseased individuals or those with elevated biomarkers.
However, supplementing did not significantly affect other markers of cardiovascular disease. No adverse effects of anthocyanins were reported when adults were taking up to milligrams per day. Examples of anthocyanins that can be isolated and taken as supplements include those called cyanidin and pelargonidin.
Cyanidin is an isolated glycoside, a subset of anthocyanin that can be taken in supplement form to support the immune system. Pelargonidin is another anthocyanidin that has a characteristic orange color. These two supplements have been shown in some studies to to help fight oxidative stress and control blood glucose sugar levels.
Long before scientific studies were conducted to isolate and investigate anthocynanin, foods containing this antioxidant were used in folk medicines around the world to improve health and fight disease. Traditional cultures have known about the healing effects of anthocyanin foods for centuries.
For example, historically, red, blue, black and purple foods have been viewed as remedies for conditions like liver disfunction, hypertension, vision disorders, microbial infections, fatigue, anxiety and diarrhea.
Black foods are said to be warming and best for winter, while red foods are cooling and best for summer. Dark-colored foods also correspond with the element water and are linked to coolness and saltiness. They are said to support organs including the stomach, spleen and kidneys by improving the ability to store energy, balancing fluid metabolism and dispelling toxins.
Red foods, on the other hand, are associated with warmth, fire, summer, happiness and bitterness in TCM. Red foods are believed to support organs including the heart and small intestine.
They help nourish blood, improve circulation, and reduce symptoms in people with anemia, palpitations, cold limbs, pale face, and lack of strength or energy. In Ayurvedic medicine , red, purple and blue foods can be viewed as either warming or cooling.
Grapes, cherries and oranges build heat, while berries, pomegranate, cabbage and eggplant reduce warmth. All types of berries are especially valued in Ayurveda, since they are viewed as capable of reducing internal heat, soothing swelling, treating inflamed tissues and helping cool the blood.
In Ayurveda, foods also correspond with certain emotions. Red foods lift energy and fight lethargy and fatigue, while blue and black foods are calming and fight anxiety.
These have been more widely studied than anthocyanin supplements and shown to have many benefits. One study found that over 30 percent of anthocyanin dietary supplements did not contain the fruit listed on the ingredient label, did not contain any anthocyanin at all or contained contents differing from those listed on the label.
Another study found that the amount of anthocyanin in supplements can vary considerably , making it hard to know how much you are actually consuming and absorbing. The minimum amount of anthocyanin foods you want to have per week is about three servings roughly one cup per serving , but more is even better.

Studies increasingly support their purported health benefits 1. Anthocyanins extracted from plants are also commonly used as dyes, natural food colorants, and food additives.
For instance, the commercial additive E is most commonly derived from grape skin and used to add a purple color to jam, candies, and beverages 1.
Anthocyanins are a group of antioxidants found in red, purple, and blue veggies and fruits. Red, purple , and blue fruits and vegetables typically boast the highest amount of anthocyanins. The following foods contain the most anthocyanins per 3.
Other anthocyanin-rich foods include purple corn, pomegranate , eggplant, black carrots, red cabbage, and purple cauliflower, which may provide anywhere from a few to — mg per 3. The anthocyanin content of these foods varies so widely because growing area, climate, season, light exposure, harvest time, and storing temperature all affect antioxidant content 6.
Amounts may also depend on whether foods are fresh, frozen, or dried — the last of which typically has the lowest anthocyanin content 7. To maximize your intake of anthocyanins from these foods, eat them raw and at their ripest if possible.
Red, blue, and purple produce is generally the richest in anthocyanins. Raw, ripe varieties tend to have the highest amounts due to variability in this nutrient. Anthocyanins have antioxidant properties, meaning that they fight damaging compounds called free radicals.
When free radicals accumulate in your body, they cause oxidative stress. In turn, this oxidative stress leads to inflammation and may increase your risk of chronic ailments, such as cancer and heart disease 3 , 4.
Anthocyanins are also believed to help reduce inflammation 3 , 4. In a week study in people with high cholesterol, supplementing with mg of anthocyanins twice per day significantly reduced markers of inflammation 8. Plus, in a 4-week study, people with and without overweight or obesity who took mg of anthocyanins daily had significantly lower blood markers of inflammation 9.
Additionally, one study suggests that these compounds may help reduce inflammation and pain in people with inflammatory arthritis Since chronic inflammation may cause several chronic conditions, including type 2 diabetes and heart disease , regularly eating anthocyanin-rich foods may help protect you from these Regularly eating foods that are rich in anthocyanins may safeguard against type 2 diabetes.
Furthermore, adding as little as 7. To put this into perspective, 7. Both of these benefits may reduce your risk of type 2 diabetes However, other studies find no effect 11 , However, anthocyanins are classified as flavonoids, a group of antioxidants believed to have strong cancer-fighting abilities 14 , These alternative treatments are less aggressive than conventional cancer drugs and appear to be especially helpful when combined with chemotherapy Like other flavonoids, anthocyanins may fight free radicals, lower inflammation, and prevent DNA damage — all factors which may help prevent tumor formation Anthocyanins may also help prevent cancer cells from multiplying and spreading.
For instance, one test-tube study suggests that they may activate certain genes that kill prostate cancer cells Anthocyanins also appear effective at preventing leukemia and ovarian cancer cells from spreading. Keep in mind that most studies have been done exclusively in test tubes or animals.
Therefore, more research involving humans — in addition to more anthocyanin-specific research — is needed.
In a week study, people who drank 6. In another, those who drank 10 ounces mL of anthocyanin-rich plum juice daily saw a significant drop in blood pressure that remained 6 hours later. While participants from all age groups experienced this drop, it was most significant in older adults In addition, anthocyanins may lower triglyceride and LDL bad cholesterol levels while increasing HDL good cholesterol levels 6 , 22 , 23 , Anthocyanins may also benefit your brain.
A recent review of randomized control trials — the gold standard in scientific research — suggests that these compounds boost your memory, attention, and brain processing speed For instance, a review of seven short- and long-term studies claims that diets rich in anthocyanins may improve verbal learning and memory in children, adults, and older adults with cognitive impairment Another review of 21 long-term studies suggests that supplementing with flavonoids improves attention, memory , and brain processing speed in healthy adults — as well as memory in children and older adults Anthocyanin-rich cherry juice appears to offer similar benefits.
In a week study, older adults with mild to moderate dementia saw significant improvements in verbal fluency and short- and long-term memory after drinking 6.
The strong antioxidant and anti-inflammatory potential of anthocyanins may benefit your brain and heart, as well as reduce your risk of type 2 diabetes and certain cancers.
Anthocyanin-rich foods are generally considered safe. However, the same cannot necessarily be said about anthocyanin supplements. Animal studies indicate that high dose polyphenol supplements may damage your kidneys , cause tumors, or unbalance your thyroid hormones Polyphenol supplements may also interact with medications and lower the absorption of certain nutrients from your diet Anthocyanin-rich foods are generally safe.
However, anthocyanin supplements may be a cause of concern. While a variety of anthocyanin supplements are available, they are regulated by the FDA as food, so less strictly than drugs.
Moreover, whole food sources of anthocyanins tend to be rich in a variety of other nutrients, which you would miss if you get anthocyanins solely from supplements.
Anthocyanins can be found in supplement form. Anthocyanins are a group of antioxidants found in red, blue, and purple fruits and veggies. A diet rich in these compounds may prevent inflammation and protect against type 2 diabetes, cancer, and heart disease.
Regularly eating anthocyanin-rich foods may also benefit your memory and overall brain health. For best effects, get these antioxidants from fresh, ripe plant foods rather than sourcing them from supplements.
