That\u2019s why I\u2019ve taken the time to sort through the most common nutrition misconceptions surrounding pregnancy, providing clear, practical and science-backed guidance. To make this as helpful as possible, I\u2019ve organised the advice by trimester, addressing the most frequently asked questions and common symptoms experienced along the way, so that you can give clients the essential nutrition guidelines for pregnancy and health.<\/p>\n<h4><strong>Trimester one<\/strong><\/h4>\n<h5><em>The symptom: Morning sickness<\/em><\/h5>\n<p>The hormonal shifts during this trimester can lead to fluctuations in blood sugar levels, often triggering morning sickness. Nausea is more likely to occur on an empty stomach \u2013 hence the term\u00a0\u2018morning sickness\u2019 \u2013 as it typically strikes when you&#8217;ve gone the longest without eating.<\/p>\n<h5>Practical strategies for easing nausea:<\/h5>\n<ul>\n<li>Eat small, regular meals: Going too long without food can worsen nausea, so aim for a steady intake of easy-to-digest foods.<\/li>\n<li>Prioritise nourishment, but don\u2019t stress about perfection: If you&#8217;re struggling to keep food down, just focus on getting\u00a0<em>something <\/em>in rather than achieving the ideal balanced diet. Nutrient-dense choices can come later.<\/li>\n<li>Ginger can be a game-changer: Studies support its role in reducing nausea. Try ginger tea, cordial, dried ginger chews or flat ginger ale. Lemon slices and dry crackers can also help settle the stomach.<\/li>\n<li>Trust your body\u2019s signals: Aversions are your body&#8217;s way of guiding you. Strong smells or spicy foods may trigger nausea, so opt for room-temperature or cold foods, which tend to have milder aromas.<\/li>\n<\/ul>\n<h4><strong>Trimester two<\/strong><\/h4>\n<p>In the second trimester, hormone levels begin to stabilise, bringing relief from early pregnancy symptoms. This is often when the renowned\u00a0<em>pregnancy glow<\/em>\u00a0appears \u2013 along with a natural and necessary increase in weight as your baby grows.<\/p>\n<h5><em>Common myth: I\u2019m eating for two<\/em><\/h5>\n<p>Sadly not. While you do need extra nutrients like calcium and iron when you are pregnant, you do not need many extra calories until the third trimester and it\u2019s only 350 calories each day. And guess what? Those extra calories need to be nutritious calories, not junk calories. If you do end up \u2018eating for two\u2019, you will simply just gain excess weight.<\/p>\n<h5><em>Myth 2: I should always give in to my pregnancy craving<\/em><\/h5>\n<p>While pregnancy cravings are a real thing (caused by hormonal changes), there is no evidence to suggest that cravings are a sign of what your body needs, as the old wives\u2019 tales makes us believe. Spoil yourself in moderation. If you have non-food related cravings (such as ice or clay) this is a condition called pica that you need to discuss with your doctor.<\/p>\n<h5><em>Myth 3: A mug of coffee is a no-no when I\u2019m pregnant <\/em><\/h5>\n<p>It can take pregnant women 1.5-3.5 times longer to eliminate caffeine from the body. However, moderate amounts of caffeine (200mg per day) have not been found to have a negative effect on pregnancy, so your daily cup of coffee is OK to keep having if you still fancy it. However, it\u2019s not just coffee that contains caffeine. Chocolate does too, so keep track of your intake across your day. If you are experiencing or have a history of high blood pressure, you should consider reducing your caffeine intake and speak to your doctor about it.<\/p>\n<h5><em>Myth 4: The occasional small glass of merlot is not allowed when you are pregnant<\/em><\/h5>\n<p>It is not clear cut how much alcohol it takes to cause health problems. The current advice is therefore that women should avoid alcohol if they are pregnant. Although, that said, it\u2019s up to each mum-to-be to consult her doctor and decide if she\u2019ll have the occasional drink or not.<\/p>\n<h5><em>Myth 5: If I avoid some foods (like peanuts, wheat or cow milk) during my pregnancy, I can prevent my child from developing food allergies<\/em><\/h5>\n<p>As the research in this area is inconclusive, it is recommended for mums-to-be not to avoid foods. Those mums who have a history of severe atopic disease (eczema, asthma, etc.) should still be vigilant about their intake of peanuts while more research is done.<\/p>\n<h4><strong>Trimester three<\/strong><\/h4>\n<p>As your bump starts to get bigger, you do experience more symptoms like constipation, heartburn and fatigue.<\/p>\n<h5><em>The symptom: Constipation<\/em><\/h5>\n<p>Constipation is a common concern during pregnancy, primarily due to hormonal changes that slow down digestion. Increased levels of\u00a0progesterone\u00a0relax the muscles of the digestive tract, causing food to move more slowly through the intestines. This allows for greater nutrient absorption but can also lead to harder, drier stools. Additionally, as pregnancy progresses, the growing uterus places pressure on the intestines, further slowing bowel movements. Other factors, such as increased iron intake from prenatal supplements and reduced physical activity, can also contribute. Staying hydrated, consuming fibre-rich foods and maintaining gentle movement can help alleviate discomfort.<\/p>\n<h5>Practical strategies to ease constipation:<\/h5>\n<ul>\n<li>Keep an eye on your fibre intake. Aim for\u00a030g per day\u00a0from a variety of sources to support healthy digestion. Incorporate a mix of\u00a0whole grains\u00a0(such as oats, brown rice, wholegrain bread and sweet potatoes),\u00a0legumes\u00a0(beans and lentils) and\u00a0fibre-rich fruits and vegetables\u00a0like kiwi, berries, mushrooms and leafy greens. Nuts and seeds, particularly\u00a0ground flaxseeds and chia seeds, are also excellent choices for promoting regularity.<\/li>\n<li>Keep your water bottle close. Hydration is just as important as fibre needs water to work effectively, so keep a water bottle with you throughout the day. If additional support is needed, psyllium husk can be a gentle, natural option to aid digestion and prevent constipation.<\/li>\n<\/ul>\n<h5><em><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-12978\" src=\"https:\/\/www.fitpro.com\/blog\/wp-content\/uploads\/2025\/02\/NL-blog-featured-image-4-300x200.png\" alt=\"nutrition guidelines for pregnancy and health\" width=\"800\" height=\"533\" srcset=\"https:\/\/www.fitpro.com\/blog\/wp-content\/uploads\/2025\/02\/NL-blog-featured-image-4-300x200.png 300w, https:\/\/www.fitpro.com\/blog\/wp-content\/uploads\/2025\/02\/NL-blog-featured-image-4-1024x683.png 1024w, https:\/\/www.fitpro.com\/blog\/wp-content\/uploads\/2025\/02\/NL-blog-featured-image-4-768x512.png 768w, https:\/\/www.fitpro.com\/blog\/wp-content\/uploads\/2025\/02\/NL-blog-featured-image-4-900x600.png 900w, https:\/\/www.fitpro.com\/blog\/wp-content\/uploads\/2025\/02\/NL-blog-featured-image-4.png 1254w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/em><\/h5>\n<h5><em>The symptom: Heartburn<\/em><\/h5>\n<p>Heartburn during pregnancy is primarily caused by hormonal and physical changes. Increased\u00a0progesterone\u00a0relaxes the lower oesophageal sphincter, allowing stomach acid to rise into the oesophagus more easily. As pregnancy progresses, the growing\u00a0uterus presses against the stomach, further contributing to acid reflux.<\/p>\n<h5>Practical strategies to ease heartburn<\/h5>\n<ul>\n<li>Eat small, frequent meals vs large meals. Focus on\u00a0smaller, more frequent meals\u00a0rather than large portions, which can put added pressure on the stomach and increase acid reflux.<\/li>\n<li>Minimise trigger foods. Identify and\u00a0avoid common trigger foods, such as spicy dishes, citrus fruits, caffeine, carbonated drinks and high-fat or fried foods, as these can relax the oesophageal sphincter or stimulate acid production.<\/li>\n<li>Pay attention to what you eat and when you eat it. You might want to skip spicy foods and not eat too close to bedtime, as this will exacerbate it. Also, don\u2019t lie down for at least an hour or so after eating a meal.<\/li>\n<li>Stay upright after eating. Remain upright for at least 30-60 minutes\u00a0to allow food to digest properly and reduce the likelihood of acid rising into the oesophagus. Sleeping with your upper body slightly elevated and wearing loose-fitting clothing can also help prevent discomfort.<\/li>\n<\/ul>\n<h5><em>The symptom: Fatigue<\/em><\/h5>\n<p>Fatigue is a common symptom during pregnancy, especially in the first and third trimesters, due to significant hormonal, metabolic and physiological changes. Increased\u00a0progesterone levels\u00a0promote relaxation and sleepiness, while the body works harder to support the developing baby, leading to higher energy demands. Additionally, increased\u00a0blood volume and\u00a0iron needs\u00a0can contribute to fatigue, particularly if iron levels are low. In later pregnancy, disrupted sleep from physical discomfort, frequent urination and hormonal shifts can further exacerbate tiredness.<\/p>\n<h5>Practical strategies to ease fatigue:<\/h5>\n<ul>\n<li>Stay hydrated: Even mild dehydration can reduce blood flow and oxygen delivery, leaving you feeling sluggish. Aim for\u00a0at least two to three litres of water per day and increase intake if you&#8217;re active.<\/li>\n<li>Prioritise iron-rich foods: Low iron levels can lead to anaemia and exacerbate fatigue. Include\u00a0iron-rich foods such as\u00a0lean red meat, beans, lentils, dark leafy greens (e.g., spinach, kale) and fortified cereals. Pairing these with vitamin C-rich foods (like citrus fruits or bell peppers) enhances absorption. If needed, consult your doctor about iron supplementation.<\/li>\n<li>Maintain balanced nutrition: Keep blood sugar levels stable by focusing on\u00a0nutrient-dense meals\u00a0with a mix of\u00a0complex carbohydrates, protein and healthy fats. Avoid excessive processed sugars, which can cause energy crashes.<\/li>\n<li>Prioritise rest and recovery: Acknowledge the immense energy demands of growing a human.\u00a0Listen to your body, nap when needed and don\u2019t hesitate to slow down. Good-quality rest is just as important as good nutrition.<\/li>\n<li>Follow the 3:2:1 rule for optimal sleep hygiene:\n<ul>\n<li>3 hours\u00a0before bed \u2013 Avoid large meals and caffeine.<\/li>\n<li>2 hours\u00a0before bed \u2013 Reduce screen time to support melatonin production.<\/li>\n<li>1 hour\u00a0before bed \u2013 Wind down with a relaxing routine, such as reading or deep breathing.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><strong>References<\/strong><\/p>\n<ol>\n<li>British Dietetic Association.
