PREGNANCY DIET & HEALTHY BABY PLAN: WEEKS 14–27 — PART 2
Weeks 14–27: The Second Trimester
The first trimester is a period of remarkable development. As pregnancy moves beyond week 13, the body enters a new stage.
Weeks 14–27 are known as the second trimester.
For many women, nausea and extreme tiredness begin to improve during this period. At the same time, the baby's growth accelerates, the mother's abdomen becomes more noticeable, and nutritional needs continue to increase.
This is the stage when a pregnancy diet should become a little more structured—not necessarily more expensive.
A healthy second-trimester diet can still be built around affordable everyday foods such as rice, dhal, eggs, vegetables, leafy greens, seasonal fruits, beans, chickpeas, green gram, fish, milk and yoghurt.
The goal is not to eat expensive foods.
The goal is to provide a variety of nutrients regularly.
Important: This is an educational guide, not an individualized medical diet. Pregnancy needs differ between women. Supplement doses, weight-gain targets, exercise restrictions and dietary changes should be discussed with an obstetrician, midwife or other qualified healthcare professional.
What Happens During Weeks 14–27?
During the second trimester, the baby continues developing rapidly.
The baby's:
- Bones continue developing
- Muscles become stronger
- Nervous system continues maturing
- Hearing develops
- Movements become increasingly noticeable
- Brain continues developing
- Organs continue growing and maturing
For the mother, several changes may occur:
- The abdomen grows
- Appetite may increase
- Breast changes continue
- Weight increases
- Constipation may occur
- Heartburn can develop
- Leg cramps may occur
- Back or pelvic discomfort may appear
- Energy may improve compared with the first trimester
This is why nutrition, movement, sleep and antenatal care remain important.
1. The Second Trimester Is Not a Time to "Eat for Two"
As pregnancy progresses, energy requirements increase, but this does not mean doubling food portions.
A common mistake is to interpret increased appetite as a requirement to eat large quantities of sweets, fried foods and processed snacks.
Instead, additional food should ideally provide useful nutrients.
For example:
Instead of:
Cake + biscuits + sugary drinks
Choose:
Fruit + yoghurt + nuts
Or
Instead of:
Large portions of fried snacks
Choose:
Egg + whole-grain bread + fruit
The quality of additional calories matters.
2. Build Every Main Meal Around Protein
Protein continues to be important because the baby's tissues are growing and the mother's body is adapting to pregnancy.
You don't need expensive meat every day.
Affordable protein sources include:
🥚 Eggs
A convenient and versatile protein source.
🥣 Dhal
One of the most useful budget-friendly foods in a Sri Lankan household.
🫘 Green gram
Can be eaten boiled or incorporated into meals.
🫘 Chickpeas
Provide protein, fibre and several micronutrients.
🫘 Cowpea
Another economical plant-based protein.
🐟 Fish
Provides protein and, depending on the species, omega-3 fatty acids.
🥛 Milk and yoghurt
Provide protein and calcium.
🍗 Chicken
Can be included when affordable.
A simple rule:
Try to include at least one meaningful protein source in each main meal.
For example:
Rice + dhal + egg + vegetables
is a much more balanced meal than:
Rice + one vegetable curry
3. Iron Becomes Even More Important
Iron is particularly important during pregnancy because the mother's blood volume increases and the developing baby requires iron.
Low iron levels can contribute to iron-deficiency anaemia.
Affordable iron-containing foods include:
- Dhal
- Lentils
- Chickpeas
- Green gram
- Cowpea
- Dark green leafy vegetables
- Eggs
- Fish
- Lean meat
A useful habit is to combine plant-based iron sources with vitamin-C-rich foods.
Example:
Dhal + leafy vegetables + tomato
followed later by:
Guava or orange
Vitamin C can improve absorption of non-haem iron from plant foods.
If an antenatal clinic has prescribed an iron supplement, it should be taken according to the healthcare professional's instructions rather than replacing it with food.
4. Calcium for Bones, Teeth and Muscle Function
The baby's skeleton continues developing during the second trimester, making calcium an important nutrient.
Calcium also has important functions in the mother's body.
Affordable sources include:
- Milk
- Yoghurt
- Curd
- Calcium-rich foods recommended locally
- Certain leafy vegetables
- Small fish eaten with edible bones
A useful budget combination can be:
Rice + dhal + leafy vegetables + small fish
or:
Oats + milk + banana
Calcium supplements may be recommended for some pregnant women, particularly where dietary calcium intake is low. The appropriate amount should be determined by the healthcare provider.
5. Don't Forget Vitamin D
Vitamin D supports calcium metabolism and bone health.
Sources include:
- Sunlight
- Eggs
- Some fish
- Fortified foods
- Certain dairy products
However, sunlight exposure does not have to mean deliberately staying in strong midday sun.
Vitamin D supplementation may be recommended depending on individual circumstances and local antenatal guidance.
Avoid taking large doses of vitamin D without medical advice.
6. Omega-3 and the Developing Brain
Fish can be an economical source of protein and omega-3 fatty acids.
Omega-3 fatty acids such as DHA are important components of the developing brain and eyes.
Examples of fish that may provide omega-3s include:
- Sardines
- Mackerel
- Salmon
- Other appropriate low-mercury fish
However, not every fish is equally suitable during pregnancy.
Some large predatory fish can contain higher amounts of mercury, which is why pregnant women should follow local food-safety advice regarding fish selection and serving frequency.
Fish should also be thoroughly cooked.
7. Fruits for the Second Trimester
There is no single "best fruit" for pregnancy.
The better strategy is variety.
🍌 Banana
Provides carbohydrates, fibre and potassium and makes an easy snack.
🍊 Orange
Provides vitamin C and can complement iron-containing meals.
🍈 Guava
A useful source of vitamin C and fibre.
🍉 Watermelon
Contains a high proportion of water and can be refreshing in hot weather.
🥭 Mango
A nutritious seasonal fruit that can be included in reasonable portions.
🥑 Avocado
Provides fibre and unsaturated fats, although it may cost more than seasonal local fruits.
🍍 Pineapple
Can be included as part of a normal varied pregnancy diet.
🍎 Apple
Provides fibre and is convenient as a snack.
🍐 Papaya
Ripe papaya can be part of a varied diet. Internet claims that ordinary ripe papaya automatically causes miscarriage are not a reliable basis for dietary advice. However, pregnant women should still follow their own healthcare provider's advice, particularly concerning unusual preparations or quantities.
The budget principle
You don't need imported berries every day.
A combination such as:
Banana + guava + papaya + seasonal local fruit
can provide variety at a much lower cost.
8. Vegetables: More Variety, Not More Expense
Vegetables provide fibre, vitamins, minerals and other beneficial plant compounds.
Try to rotate different vegetables rather than eating the same vegetable every day.
Affordable choices can include:
- Pumpkin
- Carrot
- Beans
- Cabbage
- Brinjal
- Okra
- Beetroot
- Gotukola
- Mukunuwenna
- Spinach and other leafy greens
- Tomato
- Cucumber
- Drumstick
- Sweet potato
A useful habit:
Try to include different colours of vegetables throughout the week.
Green, orange, red, purple and yellow vegetables provide different combinations of nutrients.

10. How to Save Money Without Sacrificing Nutrition
Pregnancy doesn't have to become financially overwhelming.
Buy seasonal fruits
Seasonal fruits are often more affordable than imported fruits.
Buy pulses in larger quantities
Dhal, chickpeas, green gram and cowpea can be economical sources of protein.
Use eggs strategically
Eggs can provide protein at a relatively low cost.
Choose local fish
There is no requirement to buy expensive imported fish to obtain useful nutrients.
Cook at home
Home-cooked meals make it easier to control salt, sugar, oil and portion sizes.
Don't spend heavily on "pregnancy superfoods"
Foods marketed as pregnancy superfoods are not necessarily nutritionally superior to ordinary foods.
A meal of:
Rice + dhal + leafy vegetables + egg + fruit
can be nutritionally useful without being expensive.
11. Healthy Weight Gain During the Second Trimester
Weight gain during pregnancy is normal and expected.
However, the appropriate amount varies considerably depending on the mother's pre-pregnancy body mass index (BMI), height, health and whether she is carrying one baby or more.
Therefore, there should not be one universal weight target for every pregnant woman.
Healthcare professionals normally monitor:
- Weight
- Blood pressure
- Baby's growth
- Maternal health
- Nutritional status
- Other pregnancy-specific measurements
Avoid two extremes:
"I should gain as little weight as possible."
and
"I'm pregnant, so I can eat anything."
Both approaches can be unhelpful.
The focus should be healthy nutrition and appropriate pregnancy weight gain.
12. Constipation During Pregnancy
Constipation can become troublesome during pregnancy.
It can be associated with hormonal changes, reduced activity, dietary factors and some iron supplements.
Helpful habits can include:
- Drinking enough fluids
- Eating vegetables
- Eating fruit
- Including pulses
- Choosing high-fibre foods
- Staying physically active when medically appropriate
Fibre-rich budget foods:
- Dhal
- Chickpeas
- Green gram
- Fruits
- Vegetables
- Oats
- Whole grains
- Sweet potatoes
If constipation becomes severe or persistent, discuss it with the healthcare provider rather than taking laxatives or herbal remedies without advice.
13. Heartburn and Indigestion
As pregnancy progresses, some women experience heartburn.
Some practical habits may help:
- Eat smaller meals
- Avoid lying down immediately after eating
- Eat slowly
- Identify foods that trigger symptoms
- Avoid very large late-night meals
- Stay adequately hydrated
Spicy or oily foods may trigger symptoms in some women but not others.
There is no requirement to completely eliminate spicy food unless it causes problems or a healthcare professional advises otherwise.
If heartburn is severe or persistent, discuss pregnancy-safe treatment options with a doctor or pharmacist.
14. Exercise During the Second Trimester
For women with uncomplicated pregnancies who have been advised that exercise is appropriate, regular physical activity can provide important benefits.
Walking
Walking remains one of the easiest choices.
A comfortable daily walk can help maintain fitness without requiring expensive equipment.
Swimming
Swimming can be comfortable because the water supports the body and may reduce the feeling of carrying extra weight.
Pregnancy-specific exercise
Prenatal exercise classes can be useful when led by appropriately qualified instructors.
Pelvic-floor exercises
Pelvic-floor exercises can help strengthen muscles that are important during pregnancy and after childbirth.
Gentle strength exercises
If approved by the healthcare professional, light resistance exercises can help maintain muscle strength.
15. Exercise Safety Matters
Pregnancy exercise should be comfortable rather than competitive.
She should avoid activities with a high risk of falling or abdominal trauma.
She should also avoid becoming overheated or dehydrated.
Stop exercising and seek medical advice if symptoms such as:
- Vaginal bleeding
- Significant abdominal pain
- Dizziness or fainting
- Chest pain
- Severe shortness of breath
- Fluid leakage
- Regular painful contractions
- Other concerning symptoms occur.
Women with pregnancy complications or specific medical conditions may need individualized exercise restrictions.
16. Sleep and Rest
The second trimester can feel easier than the first, but rest is still important.
A healthy routine can include:
- Consistent sleeping hours
- A comfortable sleeping environment
- Daytime rest when necessary
- Regular physical activity
- Avoiding excessive caffeine
- Limiting screen use immediately before bed
As pregnancy progresses, finding a comfortable sleeping position can become more difficult.
Pregnant women should follow the sleeping-position advice given by their own healthcare team, particularly later in pregnancy.
17. Continue Antenatal Appointments
A healthy diet cannot replace antenatal care.
During pregnancy, healthcare professionals monitor things such as:
- Blood pressure
- Maternal weight
- Baby's growth
- Blood tests
- Urine
- Anaemia
- Pregnancy-related complications
- Fetal development
Scheduled scans and tests should be attended according to the maternity-care plan.
The second trimester is also a time when some important pregnancy screening tests may be offered, depending on the country, healthcare system and individual circumstances.
18. Vitamins and Minerals Checklist
A pregnancy supplement should not simply be chosen from a supermarket shelf based on the number of ingredients.
Depending on individual needs and local recommendations, healthcare professionals may recommend:
Folic acid
Especially important in early pregnancy.
Iron
Helps prevent or treat iron deficiency and anaemia when prescribed.
Calcium
Important for bone health and may be recommended depending on dietary intake and local guidance.
Vitamin D
Important for calcium metabolism and bone health.
Iodine
Important for thyroid function and fetal development, but supplementation should follow local clinical guidance.
Vitamin B12
Particularly important for people who eat little or no animal-source food.
Omega-3/DHA
May be obtained from appropriate fish or supplements when recommended.
The important rule:
Do not combine several pregnancy supplements without checking their ingredients.
Different products may contain overlapping nutrients, and some vitamins can be harmful in excessive amounts.
19. Be Careful With Herbal and "Natural" Remedies
"Natural" does not automatically mean "safe during pregnancy."
This is particularly important with:
- Herbal drinks
- Traditional remedies
- Herbal supplements
- Weight-loss products
- Detox products
- Concentrated extracts
- Unregulated supplements
Some substances have not been adequately studied in pregnancy.
Before taking a herbal preparation or supplement, ask the doctor, midwife or pharmacist.
20. Continue Avoiding Alcohol and Limit Caffeine
Alcohol should be avoided during pregnancy.
Caffeine should also be limited. A commonly used guideline is to keep total caffeine intake below 200 mg per day during pregnancy.
Remember that caffeine isn't only found in coffee.
It can also occur in:
- Tea
- Energy drinks
- Cola
- Chocolate
- Some medicines
Therefore, consider the total amount consumed throughout the day.
21. Food Safety Still Matters
As pregnancy progresses, food hygiene remains important.
Wash fruits and vegetables thoroughly.
Cook meat, poultry, eggs and seafood appropriately.
Avoid raw or undercooked animal foods.
Avoid unpasteurized dairy products.
Store cooked foods safely and refrigerate foods that require refrigeration.
Be particularly careful with foods that have been sitting at room temperature for long periods.
Pregnancy changes the body's immune response, making certain foodborne infections more concerning.
22. A Simple Second-Trimester Daily Routine
A practical routine might look like this:
🌅 Morning
☀️ Mid-Morning
🍚 Lunch
🌤️ Afternoon
🌙 Dinner
🛏️ Night
The exact timing of supplements should follow the instructions provided by her healthcare professional.
23. The Husband's Role During the Second Trimester
The second trimester is also a great time for the husband to become more involved.
A husband can help by:
🛒 Shopping together
Choose affordable fruits, vegetables, pulses, eggs and appropriate protein foods.
🍳 Preparing meals
Pregnancy doesn't mean the mother should be responsible for every meal.
🚶 Walking together
A short evening walk can become a healthy routine for both parents.
💧 Encourage hydration
Keep water available throughout the day.
💤 Protect her rest
Pregnancy can be physically tiring even when she appears energetic.
🏥 Attend appointments
When possible, attending antenatal appointments together can help both parents understand the pregnancy.
❤️ Provide emotional support
Pregnancy brings physical and emotional changes. Listening and supporting her can be just as important as preparing healthy food.
24. The Second-Trimester Budget Formula
If money is limited, remember this simple formula:
Staple + Protein + Vegetables + Fruit
For example:
Rice + dhal + leafy greens + banana
or:
Rice + fish + pumpkin + guava
or:
Oats + milk + banana + egg
or:
String hoppers + dhal + egg + vegetables
Healthy pregnancy nutrition does not have to mean luxury groceries.
25. The Most Important Habits From Weeks 14–27
Try to build these habits consistently:
🥗 Eat variety
Don't rely on one food.
🥚 Include protein
Eggs, dhal, pulses, fish, chicken and dairy can all contribute.
🥬 Eat vegetables every day
Especially leafy and colourful vegetables.
🍌 Eat different fruits
Choose affordable seasonal options.
💧 Drink enough fluids
Make water the main drink.
💊 Take prescribed supplements
Don't skip supplements prescribed by the maternity team.
🚶 Stay active
If exercise is medically appropriate.
😴 Get enough rest
Pregnancy is physically demanding.
🚭 Avoid smoking and second-hand smoke
A smoke-free environment is important for maternal and fetal health.
🍺 Avoid alcohol
There is no known safe amount of alcohol during pregnancy.
☕ Watch caffeine
Keep total intake within recommended limits.
🏥 Attend antenatal appointments
Nutrition is only one part of a healthy pregnancy.
A Final Reminder for Weeks 14–27
The second trimester is not about finding one miracle food.
It is about building a pattern.
A mother who regularly eats affordable nutritious foods, takes the supplements recommended for her, stays hydrated, remains appropriately active, gets enough rest, follows food-safety practices and attends antenatal appointments is creating a strong foundation for the remainder of pregnancy.
The best pregnancy diet is not necessarily the most expensive one.
It is the one that is nutritious, varied, safe, affordable and sustainable.
