The A-Z Of Good Antenatal Nutrition

THE A-Z OF GOOD ANTENATAL NUTRITION

 A

Alcohol

• There is no definite safe level of alcohol intake for pregnancy.
• It is best to avoid alcohol completely as it can impact on baby’s development.

C

Constipation

• Pregnancy hormones and pressure from the growing uterus can make constipation more likely.
• Eat wholemeal bread, high fibre breakfast cereal, fruit (fresh, dried or tinned) and lots of vegetables (fresh, frozen, raw or cooked) daily.
• Include different types of fibre from beans, lentils, chickpeas, oats, nuts and seeds several times a week
• Drink plenty of water and other fluids daily, at least 2 litres.
• Exercise regularly at a mild or moderate intensity (e.g. brisk walking or swimming).

Calcium Content of Full-Fat and Low-Fat Dairy

• Low-fat dairy products (milk, cheese and yogurt) contain exactly the same amount of calcium as full-fat dairy products – the only difference is the fat content.

Cheese

• Some cheeses should be avoided during pregnancy if they are unpasteurised because they can carry listeria. These include soft, mould-ripened cheese (e.g. Brie, Camembert, Chevre/ goats cheese) and blue-vein cheese (e.g. Danish Blue and Stilton).
• Hard cheeses (Cheddar, Edam, Emmental and Parmesan) and Feta, Cottage, mozzarella, mascarpone and spreadable cheeses are safe.
• Cooking destroys all bacteria that can be harmful in pregnancy, so any cheese in cooked dishes is safe e.g. quiche, lasagne, pizza.
• If you are overweight or obese opt for low-fat varieties.

E

Eating for Two

• It is the quality of what you eat – not always the quantity – that is most important. Eat more nourishing foods and limit ‘junk’.
• You only need on average an extra 20 calories a day in the 1st trimester, 85 calories extra in the 2nd trimester, and 200-400 calories extra in the 3rd trimester.

A Healthy Snack Might Be:

• 1 medium banana or
• 1 slice of toast with butter or
• 20g of almonds (handful) and fruit
• Fruit and yoghurt
• Cheese and crackers
• Vegetables and humus
• Eggs

Eggs

• Fresh, well-cooked eggs are safe to eat during pregnancy.
• Avoid soft-boiled eggs and foods that are made with raw eggs, e.g. homemade mayonnaise, homemade mousse, homemade ice cream, homemade Caesar dressing and homemade unbaked cheesecakes.

F

Fish

• Oily fish like mackerel, salmon, trout and herring are rich in omega 3 oils and vitamin D. Include these fish 1-2 times a week.
• Shark, marlin, swordfish and Bluefin can contain high levels of mercury so these should be avoided during pregnancy.
• Tuna contains moderate levels of mercury: limit tuna to 2 medium (140g) tins or 1 steak per week.
• Avoid raw fish sushi.
• Shellfish are safe to eat as long as they are fully cooked.

Folic Acid

• To help prevent neural tube defects (NTD) you should take a 400µg folic acid supplement daily before (when stopping contraception) and up to the 12th week of pregnancy.
• Folic acid is also important for healthy red blood cells.
• You should also include folate-rich foods (green vegetables, fortified bread, citrus fruit and cereals) in your diet.
• If you have diabetes, had a previous NTD-affected pregnancy, take drugs for epilepsy or are obese you should speak to your doctor about taking a higher dose of folic acid before and up to the 12th week of pregnancy.

H

Heartburn

• Try eating small regular meals and snacks and avoid large meals.
• Avoid fatty, fried and spicy foods.
• Avoid eating 1 hour prior to bed time.
• Avoid drinking too much with meals. Sip drinks in between meals instead.

Herbal Teas and Herbal Remedies

• Do not drink more than 2 cups of fruit, berry, mint or chamomile tea a day. Use teabags rather than loose leaves, and try to make weak tea rather than strong tea.

I

Iron

• Include foods high in good quality (haem) iron such as meat, dark poultry and fish every day.
• Combine plant sources of iron (leafy green vegetables and beans), eggs or fortified breakfast cereals with vitamin C-rich foods to aid iron absorption, e.g. a fresh orange or berries with fortified breakfast cereal, grilled tomatoes with scrambled eggs.

M

Meat

• Avoid raw or undercooked meat and fish.

N

Nuts

• All nuts are safe to eat during pregnancy, even if there is a strong family history of nut allergy, asthma or eczema.
• Unsalted and unroasted nuts are a healthy snack because they are high in protein, vitamins, minerals and healthy fats.
• Only avoid them if you have a nut allergy yourself.

Nausea

• Eat little and often through the day choosing mainlystarchy foods such as toast, crackers.
• Cold, bland, non-greasy foods are often better tolerated.
• Drink fluids often through the day to prevent dehydration.
• You may find ginger-rich foods or drinks, or wrist acupressure travel bands help.
• Some nausea and food aversion is common in pregnancy and in most cases, should have eased by 16 - 20 weeks.
• Severe nausea, vomiting and weight loss needs medical attention.

S

Supplements

• Extra folic acid is necessary for the first 12 weeks of pregnancy. Take a 400µg tablet daily.
• A supplement of 5µg Vitamin D daily is also recommended.

V

Vitamin A

• Vitamin A is an essential nutrient, but high amounts are not recommended during pregnancy.
• Because liver is high in vitamin A, you should avoid it and its products, such as fish liver oils, liver paté and liver sausage.
• Avoid multivitamin tablets that may contain high levels of Vitamin A.
• Beta carotene is a pre-cursor of vitamin A found in some vegetables and fruit and is safe in pregnancy

W

Weight Gain

• You can expect to gain 0.5kg a week on average from the second trimester onwards.
• It should be slightly less if you are overweight and more if you were underweight before pregnancy or carrying twins or more.

Whipped Ice-Cream

• Avoid soft-whip ice cream as it may carry harmful bacteria.

Z

Zinc and Other Minerals

• Minerals and trace elements like magnesium, copper, selenium, iodine and zinc are also important for healthy fetal growth and development.
• They are all provided in a balanced diet that contains wholegrain starches, fruit & vegetables, milk & yogurt, fish & meat, nuts & seeds.
