What is a small dark purple fruit of South America used in smoothies and health drinks?

Quick Answer

The small dark purple fruit from South America commonly used in smoothies and health drinks is the açaí berry. Açaí berries grow on açaí palm trees native to the Amazon region. They are known for their deep purple color, small size, and nutrient density.

What is the Açaí Berry?

The açaí berry is a small, round, dark purple fruit about the size of a grape that grows on açaí palm trees in the floodplains and swamps of the Amazon rainforest. The word “açaí” comes from the Portuguese adaptation of the Tupi word ïwaca’i, meaning “fruit that cries or expels water.”

Açaí berries grow in clusters on açaí palm trees, which can reach heights of 80 feet. The trees produce round, black-purple colored fruit throughout the year, but the main harvest period for açaí berries is from August to December.

When ripe, açaí berries have a deep purple pigment and tough outer skin surrounding a layer of pulp and a large inedible seed. The seed makes up about 80% of the fruit, while the soft pulp layer contains the nutritious contents.

Açaí Berry Nutrition Facts

Açaí berries have an impressive nutritional profile, containing:

  • Healthy fats: Açaí is high in heart-healthy monounsaturated and polyunsaturated fatty acids like oleic acid and linoleic acid.
  • Fiber: A 100 gram serving contains 11 grams of dietary fiber, supporting digestive health.
  • Antioxidants: Açaí is rich in anthocyanins, a type of antioxidant that gives the fruit its deep purple color. Anthocyanins have anti-inflammatory effects in the body.
  • Plant sterols: Açaí contains beta-sitosterol, stigmasterol, and campesterol compounds that help lower cholesterol.
  • Minerals: Strong concentrations of minerals like magnesium, potassium, copper, and manganese.
  • Vitamin A: An excellent source of antioxidant vitamin A from beta-carotene.

Due to its impressive nutritional value, açaí is considered a superfood.

Uses for Açaí Berries

The two main ways açaí berries are consumed are:

Açaí Bowls & Smoothies

Açaí pulp is commonly used to make bowls, smoothies, juices, and other blended drinks. The pulp has a thick, creamy texture when blended that makes it perfect for smoothies. It also has a unique flavor described as a mix of dark chocolate and blackberries.

Some popular ingredients to blend with açaí pulp include:

  • Bananas
  • Berries like strawberries and blueberries
  • Nut milks like almond milk or coconut milk
  • Fresh fruit juices like orange, apple, pineapple, etc.
  • Nut butters like almond butter or peanut butter
  • Oats, chia seeds, flaxseeds, and other superfoods
  • Honey, agave, or maple syrup to sweeten

Açaí bowls are a thick, frozen puree made by blending açaí pulp with banana and other fruit. The frozen bowl is then topped with fresh fruit, granola, nuts, seeds, coconut flakes, nut butter, and honey or syrup.

Açaí Powder Supplements

After harvesting, açaí berries are cleaned, deseeded, and mashed into a pulp. The pulp is then freeze-dried and ground into a fine purple powder.

In powder form, açaí is sold in capsules, tablets, and as a bulk supplement. The powder is used to harness the fruit’s antioxidants and boost health. Some potential benefits of açaí powder supplements include:

  • Increased antioxidant levels for anti-aging effects
  • Lower LDL cholesterol
  • Improved circulation
  • Detoxification support
  • Immune defense
  • Neuroprotection for cognitive function
  • Anti-inflammatory benefits

The recommended dosage of açaí berry powder is 100-500 mg taken 1-2 times per day. Look for freeze-dried açaí powder without additives.

Health Benefits of Açaí Berries

Research on açaí berries shows that the fruit may offer the following potential health benefits:

1. Rich in Antioxidants

Açaí has an extremely high antioxidant capacity due to its natural plant chemicals, particularly anthocyanins and other polyphenols.

The ORAC value (a measure of antioxidant strength) of açaí is over 15,000 per 100 grams. This antioxidant power protects cells from oxidative damage caused by free radicals and may promote longevity.

2. Anti-Inflammatory Effects

The anthocyanins in açaí, like cyanidin-3-glucoside and other polyphenols, have natural anti-inflammatory abilities.

In a study on mice, açaí extract lowered levels of several inflammatory markers. This can help reduce inflammation-related diseases.

3. Improved Cholesterol Levels

Açaí may help lower LDL (bad) cholesterol while also increasing HDL (good) cholesterol. In one 90-day study in overweight adults, LDL cholesterol decreased by 27% compared to the control group.

Plant sterols like beta-sitosterol in açaí help block cholesterol absorption in the gut. The polyunsaturated fatty acids in the fruit also support healthy cholesterol.

4. Neuroprotective Effects

The anthocyanins in açaí cross the blood-brain barrier and exhibit neuroprotective qualities. They activate proteins that clear toxic amyloid-beta from the brain.

This antioxidant protection of brain cells and promotion of mental clarity makes açaí excellent brain food.

5. Supports Immune Function

Açaí is high in immune-boosting antioxidants. Animal studies reveal it increases the number of antibody-producing cells in the body.

In a 30-day study, drinking açaí pulp improved immune function markers compared to the control group.

6. Boosts Skin Health

Applying an açaí facial cream for 30 days led to improved skin appearance and moisture retention in women. This skin-protective effect is attributed to the antioxidant activity of açaí.

The fruit also contains phytosterols like beta-sitosterol that reduce irritation and inflammation in skin.

7. Anti-Cancer Activity

Test tube and animal studies demonstrate that açaí compounds inhibit the growth and spread of cancer cells for cancers like leukemia, lung, colon, breast, and melanoma.

More research is needed, but the antioxidant and anti-inflammatory activity of açaí is promising for cancer prevention.

8. Supports Weight Loss

Açaí is low in sugar and calories yet high in fiber, healthy fats, and protein – a combination that stimulates satiety and weight loss.

Studies show açaí supplements and pulp reduce belly fat, lower fasting glucose, and make people feel fuller between meals. This makes açaí an excellent food to support a healthy weight.

9. Improves Circulation

Açaí opens blood vessels to increase circulation due to its nitric oxide-boosting abilities. Better circulation can benefit heart health, cognitive function, erectile dysfunction, and exercise performance.

10. Protects Against Aging

The rich antioxidant content of açaí combats oxidative stress caused by free radicals. This can slow the aging process for benefits like younger-looking skin, reduced wrinkles, increased longevity, and protection against age-related chronic diseases.

Finding and Selecting Açaí

Look for pure açaí products without added sugars, fillers, or preservatives:

  • Açaí pulp/puree – Look for 100% pure freeze-dried açaí pulp to add to smoothies and bowls.
  • Açaí powder – Seek out pure freeze-dried açaí powders.
  • Açaí capsules or tablets – Choose supplements made from pure freeze-dried açaí.
  • Açaí bowls & drinks – Opt for bowls and smoothies made with just açaí, fruit, and natural ingredients.

When buying fresh açaí berries, choose plump, deep purple fruits without any discoloration. Fresh açaí has a short shelf life, so freeze or use them promptly.

Avoid products that list “açaí flavor” without pure açaí pulp or powder on the ingredients label, as they won’t provide the same benefits.

Possible Side Effects

Açaí berry is safe for most people when used in normal food amounts.

In supplement form, açaí is “Possibly Safe” according to safety ratings. Potential side effects can include:

  • Digestive issues like diarrhea and irritable bowel syndrome
  • Allergic reactions in those allergic to palm pollen (açaí is from the Arecaceae palm family)
  • Unsafe mercury levels with some poor-quality Brazilian açaí products

Always buy reputable supplement brands tested for contaminants. Avoid açaí supplements if you have pollen allergies or digestive problems.

Introduce açaí slowly and drink lots of water to assess your tolerance, especially when taking capsules or powder.

Interactions with Medications

Açaí may interact negatively with the following drugs:

  • Anti-diabetes medications – Açaí may lower blood sugar, increasing the effects of diabetes drugs.
  • Anti-coagulant and anti-platelet drugs – Açaí may inhibit platelet aggregation, increasing the risk of bruising and bleeding.
  • Medications metabolized by CYP3A4 – Açaí may inhibit the CYP3A4 enzyme in the liver, impacting the metabolism of these drugs.

Speak with your doctor before taking açaí supplements if you take any medications, especially diabetes or blood thinner medications. Introduce açaí slowly to check for interactions.


In summary, the açaí berry is a tiny, round, dark purple fruit that comes from the acai palm trees of the Amazon rainforest. Valued as a superfood, açaí is low in sugar yet packed with antioxidants, healthy fats, fiber, vitamins, and minerals.

Açaí has a delicious, deep berry flavor and offers great nutrition for smoothies, bowls, and health supplements. Potential benefits include improved cholesterol levels, anti-aging effects, immune defense, neuroprotection, and weight loss support.

While more research is still needed, the antioxidant richness of açaí berries shows promise for fighting inflammation, protecting the brain and heart, inhibiting cancer growth, and promoting longevity. Enjoy açaí as part of an overall healthy lifestyle for the best effects.
