Acne

We all want clear skin which is blemish free. Unfortunately for teenagers it is not that easy, and they commonly struggle with acne. Acne can affect self-confidence and negatively impact on how a person rates their body image.

For a long time it was believed that diet did not have a role to play in acne treatment, but the studies carried out were not robust enough to give clear scientific support to that argument. The role of diet was unclear.

The prevalence of acne varies widely between populations. It is generally low in non-Westernised societies where people continue to eat traditional foods. Eskimos, for instance, have no history of acne until they adopt a western diet.

A recent study in Australia helped to show the possible link between diet and acne. While further research is needed this study has positively shown how diet can affect acne.

The study looked at how the glycaemic load of a meal may affect acne. Traditional balanced diets made up of fruits, vegetables, whole grains, lean meats and less processed foods have a much lower glycaemic load than diets made up of highly refined foods. The lower glycaemic eating pattern resulted in a reduction of acne.

Meals based around choices of fruits, vegetables, wholegrains and lean proteins have a lower glycaemic load. This means that lower insulin levels are needed after eating.

If you eat a meal where food choices lead to a higher blood sugar level after eating, then you need more insulin to help maintain a normal blood sugar level. Eating patterns that can place a higher demand on insulin levels include choices such as white breads, breakfast cereals with a lower fibre level and high-sugar foods such as biscuits, soft drinks or fruit juices.

By eating a diet with a lower glycaemic load insulin levels can be reduced. The reduction in insulin levels could help control hormonal imbalances associated with acne.

Choosing foods which help to lower the glycaemic load are highly recommended as they tend to be good for us. Sometimes, as we all know, it can be hard to get teenagers to eat the ‘healthy foods’. However, if you have a teenager troubled with acne, then this could be the motivating factor for improving their diet.

Simple dietary changes that you can encourage which may help include

By following a diet with a lower glycaemic load this can also help with appetite control. We all know that many teenagers seem to have "hollow legs" and constantly crave food. By including some lean protein at each of the meals this will help to lower the glycaemic load and control appetite.

Including foods such as lean meat, skinless chicken, fish (tinned or fresh) eggs, dried beans, nuts or low fat dairy products is recommended at each meal. These foods are all good sources of protein.

The dietary recommendations above are made up of good healthy choices. Not only may it help the control of acne it will also give a good range of important antioxidants, vitamins and minerals needed by all of us.
