There are many treatments on the market for adults and children with hyperactivity. There is a major trend amongst parents to try and treat their children naturally. It is a popular belief that diet can help people with hyperactive tendencies without using drugs that cause massive side effects. For example: small portions of caffeine seem to have a calming effect instead of the reverse and sugar should be kept at a minimum.
IMPROVED CONCENTRATION
It is suggested that a high-protein diet can help improve concentration. Protein is found in all kinds of foods including meat, eggs, cheese, nuts and beans. If you have these primarily in the morning, it will help get through the tasks of school or work much easier.
SLEEP AID
Do not eat sugar close to bedtime but instead, plenty of complex carbohydrates. Vegetables and some fruits contain these. If the individual were to eat oranges, apples, pears or a grapefruit at bedtime instead of ice cream or some other sweet treat, they will feel more relaxed and will be able to get a better nights sleep. Getting a little exercise a couple of hours before bedtime is very beneficial for a good nights rest also. Taking a walk around the block or a short jog is good for you in many other ways also.
MINIMIZE HYPERNESS
You can minimize some of the hyperactivity by completely (or as much as possible) eliminating foods and drinks that contain food colorings and preservatives. Specifically red and yellow dyes. You can also reduce hyperactive tendencies by eating fewer simple carbohydrates which would include sugar, candy, corn syrup, honey, potatoes and white rice. Eating more Omega-3 fatty acids seems to help also. This food group would include tuna, salmon, walnuts, Brazil nuts, olive oil and canola oil.
