What are anthocyanins used for?

In herbal medicine, foods rich in anthocyanins are thought to treat or prevent many unrelated health conditions, including:

  • Alzheimer’s disease
  • colds, flu, and other viral infections
  • enlarged prostate
  • Eye diseases such as diabetic retinopathy and glaucoma
  • fatty liver disease
  • high cholesterol
  • heart disease
  • hypertension
  • Parkinson’s Disease
  • stroke
  • urinary tract infection

Others believe anthocyanins can help prevent breast, colon, liver, lung, ovarian, prostate, skin, and other types of cancer.

While it’s clear that anthocyanin-rich foods play a role in good nutrition, it’s unclear whether they can prevent or treat any health conditions. Even if there is evidence that anthocyanins are beneficial, such as reducing the risk of heart disease, it’s unclear how much is needed to be considered “preventive.” Evidence is still lacking.

Here are some of the current research:

heart disease

According to a review published in 2010, anthocyanins may reduce the risk of heart disease Nutrition ReviewsAccording to the report’s authors, anthocyanins appear to lower cholesterol and blood sugar levels that contribute to heart disease. They also appear to fight oxidative stress (damage caused by free radicals) that plays a role in heart disease.

Foods rich in anthocyanins may also help prevent high blood pressure, a major risk factor for heart disease, according to a 2011 study. American Journal of Clinical Nutrition.

How to Diagnose Heart Disease

breast cancer

Anthocyanins may help prevent breast cancer, according to a study published in the journal Phytotherapy research year 2010. In a series of test-tube experiments, scientists have shown that anthocyanins extracted from blueberries help inhibit the growth of breast cancer cells.

Despite these findings, there is no evidence that eating anthocyanin-rich foods or taking anthocyanin-rich supplements does the same. Further research is required.

review

While anthocyanin-rich foods are considered “heart-healthy,” there is little evidence that they actively treat or prevent any health conditions. This is especially true when it comes to anthocyanins and cancer prevention.

Precautions and Risks

Eating anthocyanin-rich fruits and vegetables may help boost your overall health by providing good nutrition. Anthocyanin-rich foods, like berries, work well in almost any diet because they are not only high in antioxidants, but also rich in vitamins, fiber, and essential minerals.

That being said, scientists have yet to determine whether taking high concentrations of anthocyanins in supplement form will help treat or prevent any health conditions.

If you choose to take anthocyanin supplements, keep in mind that supplements are not strictly regulated in the United States. Therefore, they may vary in quality and may contain ingredients that you may not want.

For better assurance of quality and purity, look for products that have been independently certified by ConsumerLab, the United States Pharmacopeia (USP), or NSF International. Certification does not mean they are safe or valid. This simply means that they contain ingredients in the advertised amount listed on the product label.

Also keep in mind that the safety of supplements for use by children, those who are pregnant or breastfeeding, or those with medical conditions has not been established.

review

Regardless of health claims, anthocyanin-rich fruits, vegetables, beans, and grains provide good nutrition. Whether anthocyanin supplements have health benefits has yet to be proven.

generalize

Anthocyanins are pigments found in certain plants that give them black, purple, blue or red. Rich in antioxidants, anthocyanins are thought to have anti-inflammatory properties and help boost the immune system.

Because of this, anthocyanin-rich foods and supplements are often used in herbal medicine to treat many unrelated health conditions. These include colds, flu, heart attacks, strokes, urinary tract infections, Alzheimer’s disease, and even cancer. Evidence to support these claims is often lacking.

Despite the health claims, anthocyanin-rich foods are nutritious and an important part of a balanced diet. The jury is still out on whether anthocyanin supplements provide any benefit.
