WHAT CAN YOUR PREGNANT CLIENT DRINK? When it comes to drinking during pregnancy, alcohol isn’t the only thing that needs to be taken into consideration, writes nutritionist and exercise scientist Brooke Turner. t is well known that alcohol should be avoided during pregnancy as there is no safe limit – but what about caffeine, kombucha, smoothies or protein powder? With confusion surrounding these beverages during pregnancy, do you know what recommendations you can make for your expecting clients? I Caffeine Australian guidelines recommend expecting women limit their caffeine intake to less than 200mg per day, which equates to about two instant coffees or three black teas. It is important for women to be mindful of their caffeine intake during the first trimester due to this time bearing the greatest risk of miscarriage, and higher consumption of caffeine having been linked to low birth weights. There has been a reasonable amount of research into consumption of caffeine during pregnancy. Studies have reported that excessive caffeine intake has been associated with a reduction in birth weight, though the exact level is still unknown. One UK study involving more than 2,500 women confirmed that a maternal intake of more than 300mg per day was associated with low birth weight or foetal growth restriction, and that no ill effects were recorded in the babies of the women who consumed 100mg or less daily. It is also important to consider other sources of caffeine, such as chocolate, soft drinks and energy drinks. Consumption of these contribute to daily caffeine intake. The table over the page lists some common sources of caffeine and their concentration levels. With regards caffeine and micronutrients, tannins found in caffeinated substances, like tea and coffee, can inhibit the absorption of iron, as can calcium (think milky coffee). If clients are struggling with iron levels, then check in with them on how much coffee, tea or chocolate they are consuming per day, advise them to have any pre-natal vitamins they may take at a separate time from their coffee, and ensure they are meeting their recommended daily intake of vitamin C, which assists with the absorption of iron. THE QUICK READ • Pregnant women should not consume more than 200mg of coffee per day • Inclusions of protein and fat sources in smoothies are beneficial for tissue growth, cognitive and retinal development of the growing baby • Smoothies are a great way to hit micronutrient requirements during pregnancy, particularly in women who become averse to fresh fruit and/or vegetables due to morning sickness or nausea • Protein powders can be useful throughout pregnancy, however, not all are created equal and artificial sweeteners, additives, fillers and stimulants should be avoided • Pregnant women should choose a diet high in fresh, whole, healthy foods and engage in regular physical activity.
