Nutrition and Lifestyle During Pregnancy

Introduction to Healthy Pregnancy Nutrition

• A balanced diet that includes essential vitamins, fiber, and other nutrients is crucial for supporting pregnancy health, with guava being a beneficial fruit due to its high content of vitamins, fiber, and other nutrients that can help manage pregnancy-related constipation, which affects 20-40% of pregnant women 1

Benefits of Specific Foods and Beverages

• Guava consumption can contribute to the recommended daily intake of 400 μg of folate, as suggested by the American College of Obstetricians and Gynecologists, and it also provides vitamin C that supports immune function and iron absorption 2, 3
• Peppermint tea and chamomile tea may help with digestive issues, nausea, and sleep, with no significant increase in risk of low birth weight, as shown in studies 1

Safety Profile of Herbal Teas and Supplements

• Certain herbal teas like licorice root, black cohosh, and dong quai may be potentially harmful during pregnancy due to their effects on cortisol levels, uterine contractions, and estrogenic effects, and yerba mate and some specialty teas with added caffeine should be consumed in moderation due to their high caffeine content 1
• Guava fruit is not listed among plants with known abortifacient or teratogenic properties, and its safety profile during pregnancy is favorable, with no specific warnings against consumption in pregnancy guidelines or drug safety databases 1

Consumption Guidelines for Pregnant Women

• Pregnant women should consume guava and other fruits in moderation as part of a balanced diet, ensuring the fruit is thoroughly washed to remove potential pesticides or contaminants, and fresh guava is preferable to processed forms with added sugars or artificial ingredients 1
• The American Heart Association recommends being mindful of added sugars in guava juice to avoid excessive weight gain during pregnancy, and individual food sensitivities or allergies should be considered 1
• Herbal tea consumption should be limited to 2-3 cups daily, with caffeinated teas counted toward the 200 mg daily caffeine limit, and tea should be consumed between meals to minimize impact on iron absorption, as recommended by the American College of Cardiology 1

Caffeine Intake Recommendations

• Pregnant women should limit caffeine intake to 200 mg/day, while children and adolescents should not exceed 2.5 mg/kg body weight per day, as recommended by general medical guidelines and supported by the European Food Safety Authority and the American Academy of Pediatrics 4, 5
• The recommended daily caffeine intake is:

• Average caffeine intake in the US is approximately 165 mg/day, with coffee being the primary source of caffeine, and filtered coffee is preferable to boiled or percolated coffee due to its lower content of compounds that can increase cholesterol 5

General Dietary Recommendations

• Choose organic tea options when possible, use commercial tea bags from reputable companies, and avoid teas with artificial additives or sweeteners, as well as discussing tea consumption with a healthcare provider 1
• Be aware that "natural" doesn't always mean "safe", as herbs contain bioactive compounds that can affect pregnancy, and individual responses to herbal teas may vary, with concentration of active compounds varying by preparation method 1
