Fat and protein can interfere with the absorption of anti-Parkinsonian drugs – dopamines – so foods high in fat and protein should be avoided. Dopamines should be taken about 30 to 60 minutes before a meal to ensure maximum effectiveness of the drug. If a patient feels an upset stomach when taking dopamines on an empty stomach, eat a few pieces of chocolate, juice or a small amount of crackers with the medication. Proper sun exposure helps the body synthesize vitamin D and facilitates the absorption of calcium, which is great for bones. Iron is an important element in the body’s production of hemoglobin, which helps transport oxygen to each cell. When patients cannot get enough iron from the diet, they should consult their physicians or dietitians to take some iron supplements. Nutritional supplements should be taken separately from the anti-Parkinson’s disease medication, dopamine, so as not to interfere with the effectiveness of the medication.
