Purines are important compounds your body uses to encode genes and produce energy. They are also essential for the growth and development of your little one if you are pregnant. Your body can produce purines, which are also obtained in foods, most notably animal products. Your body breaks down purines from food into the waste product uric acid. Too much uric acid -- especially during pregnancy when your metabolism is changing -- can worsen gout, arthritis and kidney and bladder problems. It could also cause complications if you've received an organ transplant, according to Metro West Medical Center.
1 Eat smaller, more frequent meals throughout the day. Smaller meals means eating fewer purines; thus, there is less uric acid for your body to handle at any one time, regardless of the specific foods you may eat.
2 Limit red meat, poultry, fish and shellfish to between four and six ounces, which is approximately two to three palm-sized servings per day. Keep up your protein intake with low-fat milk, yogurt or eggs. Avoid organ meat entirely as it is especially high in purines. Peas, beans, lentils and other legumes are also high in purines and should be limited to no more than one cup per day.
3 Increase your fluid intake to at least 8 to 12 cups of water per day, which will help remove excess uric acid in your body without stressing your kidneys. Avoid alcohol, which you'll probably be doing anyway if you are an expectant or recent mom.
4 Keep your daily intake of fat to below 30 percent of your total daily calories. This means eating more complex carbs and more plant-based protein. Safe sources of carbs include whole grains, fruits and vegetables. However, you should limit or avoid oatmeal, wheat germ, wheat bran, spinach, asparagus and cauliflower.
5 Meet with your doctor or a dietician to develop a personalized meal plan that helps limit your purine intake and meets your daily nutritional requirements.
