The
acai berry is the fruit of the Acai palm. It is an important food in many
Central and South American cultures, where the plant originated. A study found
that 42% of the total food intake by weight of the Caboclo populations of the
Brazilian Amazon is comprised of Acai berries.
Many
companies selling acai berry products tout it as a superfood that will cure
anything that ails you. However, there isn't much science to back up many of
those claims. That doesn't mean that Acai isn't good for you. Like other
berries, it contains many compounds and antioxidants that may improve your
health.
Cancer
Prevention
Acai berries contain anthocyanins, a type of antioxidant that is believed to
play a major role in the prevention of cancer. Anthocyanins are present in all
berries (they are responsible for the rich black, red, and purple colors of
berries) and research has found that they may have a significant preventative
effect on cancer.
Lower
Cholesterol
A study published in the journal Nutrition found that rats fed high fat diets
along with acai pulp had lower levels of total and LDL ("bad")
cholesterol than rats who were fed high fat diets without acai pulp. The
anthocyanins in acai may also help to lower cholesterol levels.
The
plant sterols (phytosterols) found in acai berry (B-sitosterol, campesterol,
and sigmasterol) have been proven to prevent the digestive system from
absorbing cholesterol from foods.
Heart
Health
A study published in the June 2011 issue of the journal Atherosclerosis found
that acai juice protects against atherosclerosis (hardening of the arteries) by
inhibiting pro-inflammatory cytokine production. The cholesterol-lowering
benefits mentioned above also contribute to acai's role in maintaining a
healthy heart.
High
in Antioxidants
Purple acai has been found in studies to have high levels of antioxidant
activity. Antioxidants are beneficial because they fight against the free
radicals, high amounts of which are associated with lower rates of cancer,
heart disease, and stroke.
Immune
System Support
The antioxidants in acai, including high levels of vitamin c, may help to boost
the immune system.
Anti-Inflammatory
There have been some promising results in studies that show acai may help with
the symptoms of diseases due to chronic inflammation such as asthma and
autoimmune disorders. One study found that acai may be a natural COX-1 and
COX-2 inhibitor, meaning that it may help to inhibit pain and inflammation
without the side effects of over-the-counter or prescription COX-1 and COX-2
inhibitors.
Anti-Aging
The antioxidants in acai may help to reduce the effects of aging. Flavonoids
and anthocyanins protect the cells within the body and can reduce cell
degeneration, helping to keep the body healthy and youthful.
Weight
Loss
Companies selling acai often claim that it speeds up the metabolism. Though it
does contain amino acids believed to be essential in a healthy metabolism,
there is still very little scientific evidence to prove that eating acai berry
alone aids in weight loss. That being said, acai berries are quite high in
fiber and low in calories and any food with those qualities, when eaten in
place of calorie-laden snacks, will helps a person to maintain a healthy
weight.
