Does acai berry have highest anti-oxidant
levels than some commonly used fruits like pomegranate,blueberries etc?
Recent revelations establish that it has no
extra beneficial nutrients than some of commonly used fruits like mango,
blueberry, pomegranate etc. This berry has been traditional staple food of
Amazon basin tribes but recently has gained recognition in the United States as
so-called "super food.” Nonetheless, this wonderful berry has very good
levels of anti-oxidants, minerals, and vitamins that would benefit overall
health and fitness.
Acai berry is a small, round, dark purple
fruit obtained from acai palm tree. Botanically, acai belongs to palm orArecaceae family
of trees in the genus Euterpe and known as Euterpe oleracea.
Each berry measures about the size of small
sized grape, 2-3 cm in diameter. They are dark green initially then turns to
dark purple color once reach maturity. Technically, the fruit is a drupe,
consists of outer edible pulp surrounding a central large seed. Only the outer
pulp, comprising about 10-15% of berry weight, is edible.
Acai palm is a tall, slender tree, which
grows 15 to 25 m in height. The average mature plant has 3-10 well-developed
stems (10-18 cm in diameter) from a single seed and root system. It grows
better under waterlogged low-lying plains receiving good annual rainfall. Each
stem behaves like individual tree and bear 3-5 bunches with each bunch holding
about hundreds of berries in a way similar to areca palm or coconut palm.
Health benefits of acai berry
- Acai berry has very good levels of anti-oxidants, minerals, and vitamins that have health benefiting and disease preventing properties.
- Unlike other berries and fruits, acai has high caloric values and fats. 100 g of berries provide about 80-250 cal depending up on the preparation and serving methods. In fact, fresh acai berry has been the staple nutritious diet of native Amazonians for centuries. There is no research evidence that the use of these berries will help you lose weight.
- Acai berry contains many polyphenolic anthocyanin compounds like resveratrol, cyanidin-3-galactoside, ferulic acid, delphinidin, petunidin as well as astringent pro-anthocyanidin tannins like epicatechin, protocatechuic acid and ellagic acid. Scientific studies on these compounds suggests that these compounds have been claimed to act as anti-aging, anti-inflammatory, anti-cancer functions by virtue of their anti-free radical fighting actions In addition tannins are known to have anti-infective, anti-inflammatory and anti-hemorrhagic properties.
- Preliminary research studies suggest that ellagic acid in acai has anti-proliferative properties due to its ability of directly inhibiting the DNA binding of certain carcinogens, including nitrosamines toxins in the food.
- Acai berry is also rich in medium chain fatty acids like oleic acid (omega-9) and linoleic acid (omega-6). These compounds help reduce LDL-cholesterol level and raise good HDL-cholesterol levels in the body as well as help prevent heart disease. In addition, they help prevent skin dryness by maintaining adequate moisture in the skin
- Acai pulp has good levels of dietary fiber. Good fiber in the diet helps remove cholesterol in the stools.
- ORAC value (oxygen radical absorbance capacity) of acai berry is thought to be at mid-level range for fruits, higher than that of oranges but less than pomegranate. USDA so far not validated exact ORAC value of acai.
- Acai berries contain good amount of minerals like potassium, manganese, copper, iron, and magnesium. Potassium is an important component of cell and body fluids that helps controlling heart rate and blood pressure. Manganese is used by the body as a co-factor for the antioxidant enzyme, superoxide dismutase.
- They are rich in B-complex vitamins and vitamin-K. Contain very good amounts of niacin, vitamin B-6 and riboflavin. These vitamins are function as co-factors and help body in the metabolism of carbohydrates, proteins, and fats.
