Monounsaturated and omega 3 are the fats that should be included in diet. Getting enough omega-3 during pregnancy is important, but it can be confusing to understand which foods provide what you need.

Omega-3 fatty acids fall into two categories:

  • ALA: found in a range of plant sources, including chia seeds, ground flaxseed, rapeseed oil, walnuts, hazelnuts, pecans and green leafy vegetables. ALA can’t be made by the body so it’s important to get enough from these sources. Omega-3 enriched eggs are also a good source.

  • DHA and EPA: long-chain omega-3 fats have important benefits to brain development, especially in pregnant women and young children. The body can make these from ALA but not as efficiently as consuming them directly. Fish oil and microalgae-based omega-3 supplements are available, as are omega-3 enriched eggs.

Fish liver oil supplements should be avoided because they also carry high amounts of vitamin A. Foods which are higher in monounsaturated fats are foods like olive oil, sesame oil, peanut oil, canola oil, avocados, nuts, seeds.


Fiber

It is very important to have fiber in the diet as it helps the metabolism and also improves the bowel movement and reduces constipation.

Women are more prone to develop constipation and also the risk of having haemorrhoids is higher in pregnancy. Increasing the fiber content in diet is very important to avoid constipation in females. Hence, it is very important to have plenty of fibers in the diet of a pregnant female.

  • Uncooked or partially cooked meat- Uncooked or partially cooked food carry risk of developing bacterial or viral infection in woman, but it may also pose harm to the growing baby.

  • Alcohol consumption- Alcohol consumption is not advised in pregnant females. Growing fetus cannot process alcohol during fetal life as well as even in their growing ages. Hence, consumption of alcohol should be avoided during pregnancy. Few researches say that, very small amount of alcohol may be recommended during each week, however, heavy drinking is totally restricted and may cause severe damage to the growing fetus and mother as well. Conditions like fetal alcoholic syndrome may be noted in cases where mother is a heavy drinker . So, most of the doctors advise to avoid drinking alcohol completely during pregnancy.

Iron

Iron is the major component of hemoglobin. It carries oxygen in the body . During pregnancy there is increased demand of iron for the extra need of the growing baby. Decrease in the iron count can cause anemia which can pose risk of various defects in the baby like; preterm delivery, low birth weight, still birth, new born death. A pregnant woman requires 27mg of iron , which is mostly obtained very well from normal healthy diet, but if it is reduced too much then supplements may be required.

Pregnancy diet misconceptions


Morning sickness:


When a mother-to-be is experience morning sickness, the biggest mistake she can make is thinking that if she doesn't eat, she'll feel better, Krieger said. 


The exact causes of morning sickness are not known, but it may be caused by hormonal changes or lower blood sugar, according to the Mayo Clinic. This common complaint can bring on waves of nausea and vomiting in some women, especially during the first three months of pregnancy. 


Studies say that, feeling of nausea or vomiting can be in any time of the day.


Food cravings:


It is common for women to develop a sudden urge or a strong dislike towards food during pregnancy. Some common cravings are for sweets, salty foods, red meat or fluids, Krieger said. Often, a craving is a body's way of saying it needs a specific nutrient, such as more protein or additional liquids to quench a thirst, rather than a particular food, she said. 


Eating for two:


When people say that a pregnant woman is "eating for two," it doesn't mean she needs to consume twice as much food or double her calories. During the first three months, their calorie needs are basically the same as they were before pregnancy. During the first trimester, the recommended weight gain is between 1 and 4 pounds pregnant women is advised add 200 calories to their usual dietary intake during the second trimester, and to add 300 calories during their third trimester when the baby is growing quickly.


Healthy snacks in pregnancy

If you get hungry between meals, try not to eat snacks that are high in fat and/or sugar, such as sweets, biscuits, crisps or chocolate. Instead, choose something healthier, such as:

  • small sandwiches or pitta bread with grated cheese, lean ham, mashed tuna, salmon, or sardines, with salad

  • salad vegetables, such as carrot, celery or cucumber

  • low-fat, lower-sugar fruit yoghurt, plain yoghurt or fromage frais with fruit

  • hummus with wholemeal pitta bread or vegetable sticks

  • ready-to-eat apricots, figs or prunes

  • vegetable and bean soups

  • a small bowl of unsweetened breakfast cereal, or porridge, with milk

  • milky drinks

  • fresh fruit

  • baked beans on toast or a small baked potato

  • a small slice of malt loaf, a fruited tea cake or a slice of toasted fruit bread


Preparing food safely

  • Wash fruit, vegetables and salads to remove all traces of soil, which may contain toxoplasma (a parasite that can cause toxoplasmosis) which can harm your unborn baby.

  • Wash all surfaces and utensils, and your hands, after preparing raw foods (poultry, meat, eggs, fish, shellfish and raw vegetables) to help you avoid food poisoning.

  • Make sure that raw foods are stored separately from ready-to-eat foods, otherwise there's a risk of contamination.

  • Use a separate knife and chopping board for raw meats.

  • Heat ready meals until they're steaming hot all the way through – this is especially important for meals containing poultry.

You also need to make sure that some foods, such as eggs, poultry, burgers, sausages and whole cuts of meat like lamb, beef and pork, are cooked very thoroughly until steaming all the way through.
