Ingredients

For 2 portions. Tick items as you go — nothing is changed for anyone else.

2 whole mackerel, cleaned and scored
500 g yam, peeled and cut into rounds
3 medium tomatoes, washed and chopped
1 medium onion, peeled and sliced
1 medium green bell pepper, washed and diced
2 tbsp groundnut oil
1 tsp fresh ginger, grated

This recipe contains foods that can contribute to a varied and balanced diet during pregnancy.

Method

Step 1. Boil the yam rounds in lightly salted water for 20 minutes until tender.
Step 2. Rub the mackerel with a little oil and ginger and grill for 6–8 minutes each side.
Step 3. Meanwhile heat the remaining oil, soften the onion, then add the tomato and pepper and cook for 8–10 minutes.
Step 4. Check the fish is cooked through — the flesh should be opaque and flake easily from the bone.
Step 5. Serve the fish with the yam and spoon the vegetable sauce over.

Food safety

Wash fruit, vegetables and leafy greens in clean water before cooking or eating raw.
Cook eggs, chicken, meat and fish thoroughly, and keep raw and cooked foods on separate boards and plates.
Cool leftovers quickly, refrigerate where you have reliable power, and reheat once until piping hot throughout. If refrigeration is unreliable, cook only what you will eat.
Anyone planning a pregnancy is generally advised to take a daily folic acid supplement before conception — ask your doctor, pharmacist or fertility clinic what is right for you.
Commonly eaten fish such as tilapia, croaker, mackerel and sardines are the everyday choices here. Large predatory fish such as shark, swordfish and marlin are best limited, as they may contain higher levels of mercury.

Supplements and drinks

The Federal Ministry of Health and the World Health Organization advise a daily folic acid supplement (usually 400 micrograms) before conception and through early pregnancy to help prevent neural tube defects. Folate-rich foods such as ugu, soko and beans do not replace the supplement. Buy supplements that carry a valid NAFDAC registration number from a registered pharmacy, and ask your doctor whether you need a higher dose.
Iron and folic acid supplementation is routinely recommended in pregnancy in Nigeria, and anaemia is common. Ask your doctor or antenatal clinic which supplements you need rather than buying combinations yourself, and check that any product is NAFDAC-registered.
There is no known safe level of alcohol in pregnancy, and locally brewed drinks vary widely in strength, so the safest course when trying to conceive is none. Keep caffeine moderate — around 200 mg a day, roughly two mugs of instant coffee. Recipes here contain no alcohol.
