Know What To Eat And Drink to Receive Sustained Energy? Acai Berries!

By Jeremy Liddle

Well what is it about acai berries that delivers sustained energy?

Carbohydrates and fibre, but not all carbohydrates provide sustained energy. Carbohydrates, when digested, release glucose, or sugar into the blood. Some carbohydrates cause the sugar to be released very quickly, whereas others cause it to be released more slowly. The measure of the extent of the sugar rise caused after a food is eaten is called the Glycemic Index (or GI). The lower the GI of a food, the slower the food is digested and absorbed, producing a gradual rise in blood sugar levels. Foods such as white bread or jelly beans, when eaten, cause blood sugar to rise very quickly.

Blood sugar levels need to be maintained at a normal level in order to keep the body healthy and working efficiently. So if blood sugar levels rise it stimulates the pancreas to deliver insulin into the blood. Insulin is the substance that tells all the cells to absorb more sugar, in turn causing blood sugar to reduce again. When foods that contain or release too much sugar are eaten, the body releases extra insulin. The extra insulin results in too much sugar being absorbed and then the sugar level dropping below the healthy level. This is what happens and what is experienced after a sugar rush. This activity does not deliver sustained energy and can leave the person feeling low on energy.

Acai berries have been tested by some companies in Australia and have been found to have a Glycemic Load (GL) of 0.5. GL is a more recent and more accurate way to measure the effect of particular carbs in the blood. It gives a more complete picture than GI as it is also calculated taking into account the actual amount of Carbs that have been consumed. A Gl of 11 or less is considered a low level, and so a food with such a result helps to control blood sugar levels and lowers the risk of diabetes and heart disease. Acai berries have a GL of 0.5, which means it can delver sustained energy.

The dietary fibre in Acai acts like a sponge, mixes with all the digestive juices in our bodies binding to the good eaten, and helps to slow down digestion. Instead of getting a sugar rush after a meal, the sugar is released slowly, providing sustained energy! This also helps control appetite and delays hunger. Which means that it may help prevent weight gain and therefore the risk of obesity.

Most of the energy in Acai actually comes not from sugar but from the healthy omega-6 and omega-9 fats, so acai is one food that can be eaten guilt free! It can help people feel full due to the fibre content, and at the same time provide sustained energy. It is best to mix acai with apple juice, which also has a relative low GI, to delivery sustained energy in a smoothie. - 17268
