To reduce your risk of another miscarriage, you should eat a well balanced diet that contains the four food groups: fruits and vegetables, protein, dairy and grains.  Make sure your daily diet consists of five portions of fresh or frozen fruit, six ounces or less of protein like meat, fish, eggs, soya, or tofu, three to four servings of fresh or frozen vegetables, six to eight servings of grains like bread, rice, pasta, and breakfast cereals, and two to three servings of dairy like yogurt and hard cheeses.  It is also important that you maintain a healthy weight for your age and body type. Avoid being underweight or overweight. You can calculate your Body Mass Index (BMI) using an online BMI calculator and determine how many calories per a day you should be consuming to maintain a healthy weight. When you are recovering from a miscarriage, it is important that you avoid intense exercise and focus on mild activity, like walking, yoga or meditation. Maintaining a daily exercise routine will keep you feeling healthy and energized. It can also ensure your body is at its best and ready to conceive again. Doing gentle exercise like yoga can also help you reduce any stress or anxiety you may be experiencing due to the miscarriage. Managing your stress is essential to remaining healthy and ready for pregnancy. Maintaining a well balanced diet and a healthy weight through exercise will provide your body with many essential nutrients and minerals. But prenatal vitamins and supplements like folic acid have been shown to reduce the risk of a miscarriage and having a baby that is premature or small for its gestational age. Talk to your doctor about taking folic acid supplements to help you recover from the miscarriage. Folic acid supplements can help to reduce the risk of neural tube defects like spina bifida, where your baby’s spinal cord does not develop normally. Once you become pregnant, you will be prescribed folic acid supplements free of charge. Research has shown that drinking, smoking, and caffeine consumption can increase your risk of a miscarriage.  Limit or cut out alcohol from your diet. Women who drink every day and or more than 14 units a week have a higher risk of miscarriage. Stick to one to two units of alcohol a week or stop drinking completely while you try to conceive. If your partner is a heavy drinker, this could reduce the quantity and quality of his sperm. Be safe and cut down on smoking or stop smoking while you try to conceive. Pregnant women are told to limit their caffeine intake to 200mg a day, or two mugs of coffee. Keep in mind caffeine can also be found in green tea, energy drinks, and some soft drinks. There may also be caffeine in certain cold and flu remedies and in chocolate. Try to cut down on caffeine, especially when you are trying to conceive. Unless your doctor recommends certain medications to treat an infection or other medical issue, you should avoid all medications and drugs when you are trying to get pregnant. Avoid over the counter medications, as well as herbal remedies. Herbal remedies are not regulated by the Food and Drug Administration (FDA), so you should always check with your doctor before you take any herbal remedies or medications.  If you are taking antibiotics for an infection, wait until you have completed the antibiotic course and the infection has cleared up to try to conceive. If you are taking medication for an ectopic pregnancy, wait three months after methotrexate treatment to try to get pregnant. If you are being treated for an illness or infection, wait until you have finished the medication course before you try to conceive.
