I would strongly recommend that you check out http://www.kellymom.com for breastfeeding concerns. It is a wonderful site with research backed information and helped me a lot when I was breastfeeding my children.

Here's is the link to find info about food:

You don't have to be as strict with your food intake as you were when you were pregnant. You can pretty much eat whatever you want, but should avoid large amounts of fish containing mercury (12 oz/week) and fish like shark, swordfish and mackeral should be avoided due to large amounts of mercury which transfers into the breastmilk. http://www.kellymom.com/nutrition/mom/mom-foods.html#fish

It is advisable to limit caffeine and alcohol as some does go into breastmilk. Eating unpasteurized cheese is fine while breastfeeding (not when pregnant) if it the cheese does have bacteria (listeria) it will make the mother sick with flu like symptoms and can be fatal in people with serious health problems. Research has been done and listeria is not transmitted through breastmilk. Most cheese made in the US is pasteurized, you can buy pasteurized feta, and other soft cheese.

Here's the link with the info about soft cheese, hot dogs, deli meat, etc... while nursing:

If your baby seems to be having an adverse reaction after you eat something, you might want to limit or cut it out completly. Some common allergens in breastmilk for babies are cow's milk protein and peanuts. Garlic made my daughter very gassy and crampy so I needed to cut back on garlic when I was nursing.

You should maintain a healthy diet while breastfeeding and make sure you are getting enough calories.

As far as fish goes, when you're breastfeeding you should continue to avoid seafood high in mercury just like you did during pregnancy (such as swordfish, shark and king mackerel). Fish like salmon, trout, catfish and shrimp should be safe, but it's wise to check the guidelines in your area to make sure there aren't any types of fish you should avoid eating.

The main thing to remember is anything you eat, your nursing baby will ingest as well. Keeping that in mind, it's best to avoid foods that might cause your baby to be gassy or that will upset his or her stomach. If you suspect your baby is colicky or is experiencing allergic reactions to any foods, you'll have to monitor your food intake much closer.

I've included two great articles for you about what to eat and what to avoid while nursing an infant.

All the same rules apply if your breastfeeding

The simplest to remember, everything you eat, baby will too!
Makes you think twice!

I am not a doctor, but when I had my baby, I started eating the fish and cheese and lunchmeat, etc, right away. I believe the fish is an issue due to mercury, and the soft cheeses and deli meat due to bacteria, but once you're not pregnant anymore, I don't think those kinds of things pass into breastmilk or cause a problem.

The foods I still didn't eat are the ones that could pass into breastmilk, such as spicy food, caffeine, or gas-causing foods. Also herbal teas that were unclear on what the ingredients were.

Here is a page from the La Leche League on foods to avoid (but it basically says that anything goes):

I'd talk to your doctor to be sure, but that was my experience. Good luck!

If you are still nursing then you have to still watch what you eat like you do when you’re pregnant. Everything you eat will affect the taste of your breast milk. If you eat spicy foods, your baby will be able to tell and may not want breast milk. You should also stay away from fish because mercury can be very harmful to the child. If you are not sure what to eat, you should discuss it with your doctor. You also need to make sure you are getting enough calories and nutrients because, even though, your body does not produce bad milk for the child, you will not get enough nutrients.

Many breastfeeding mothers worry about what food they should be eating. The answer is simple; your diet should be varied, but try and avoid fish with mercury

Everyone is told about the importance of eating fresh fruit and vegetables; this is more so for a breastfeeding mother. A nursing mother should aim to eat 5 portions each day. As well as eating five different portions, a mother should vary the fruit and vegetables she eats as not all vitamins and minerals can be got from one single food item.

Starchy foods are important as they will help give you energy. Being a mother of a young child is an exhausting time, so you need all the energy you can get. Starchy foods include bread, pizza, pasta, rice and potatoes.

After childbirth many women experience bowel problems and can find constipation particularly painful. Fiber can help ease or eliminate both of the conditions. Fiber can be found in wholegrain bread, pasta, rice, pulses, fruit and vegetables.

Protein is needed for muscle development. Sources of protein include lean meat, chicken and fish - you should try for at least two servings of fish a week, including one of oily fish. Eggs and pulses (such as beans and lentils) are another good source of protein.

Calcium is vital in maintaining healthy bones for both mother and her breastfed child. Dairy foods such as milk, cheese and yogurt contain plenty of calcium. Remember, there's just as mush calcium in skimmed or semi-skimmed milk as there is in full-fat milk. Non-milk calcium foods include sardines, tofu, figs, almonds, cooked spinach and tahini paste.

There are some foods you should avoid when breastfeeding. Eating shark, swordfish and marling is best avoided and you should limit the amount of tuna you eat. Don't eat more than one tuna steak a week or two medium-sized cans of tuna a weeks. The reason for not eating these fish is because of the levels of mercury. Some of the mercury in the fish you eat will pass into your breastmilk and high levels of mercury can harm a very young baby's developing nervous system.

All other foods should be eaten in moderation while you're breastfeeding. As a general rule, if a food affects you it will probably affect your baby. But remember, it's normal for breastfed babies to have loose stools.

If you're breastfeeding you should take 10 micrograms of vitamin D. This vitamin can be produced by the body but only when your skin is exposed to constant sunshine. If you have any doubts or questions, consult your doctor.

Many breastfeeding mothers are tired and too busy to make sure that their diet is as it should be. However, if your eating enough and feel fine yourself, chances are so is your baby. Breastmilk is a resilient foodstuff. Your breasts are remarkable at producing the right consistency of milk necessary to give your child the best start in life, even if your diet is less than perfect.

Take a creative approach to nutrition, choosing foods that require little or no preparation. Quick, nutritious foods include fresh fruit, raw vegetables, melted cheese on toast, cottage cheese, and yogurt with raisins, sunflower seeds, nugget-type cereal, or low-fat granola. Broiled meats and fish are faster to prepare than casseroles.
