Nutritional Therapy for Narcolepsy
Eat a low-fat diet high in cleansing foods such as leafy green vegetables and sea vegetables. Also eat foods high in the B vitamins, such as brewer's yeast and brown rice.
Include in the diet foods rich in the amino acid tyrosine. Good choices include eggs, oats, poultry, and wheat germ.
Caution: If you are taking an MAO inhibitor drug, avoid foods containing tyrosine, as drug and dietary interactions can cause a sudden, dangerous rise in blood pressure.
Eat foods high in protein (meats, poultry, cheese, nuts, seeds, and soy products) in the middle of the day, and save the complex carbohydrates (fresh fruits and vegetables, legumes, natural whole grains, and pasta) for the evening meal. High-protein foods increase alertness, whereas carbohydrates have a calming effect and can promote sleepiness.
Avoid alcohol and sugar. They may seem stimulating initially, but will only make you tired later.
Discuss food and medicine limitations thoroughly with your health care provider or a qualified dietitian.
