trying to eat well may mistakenly assume that more is better when it comes to vitamin - mineral supplements. This is simply not true, many vitamin are toxic when taken in excess, and the minerals are even more so, some at levels not far above recommendations. g) Caffeine Caffeine crosses the placenta, and the developing foetus has a limited ability to metabolize it. For this reason, pregnant women may wonder whether they should give up coffee, tea, and colas because of their caffeine contents.
Research studies have not proved that caffeine (even in high doses) causes birth defects in human infants (as it does in animal), but limited evidence suggests that moderate - to - heavy use may lower infant birth weight. h) Weight loss dieting Weight loss dieting, even for short periods, is hazardous during pregnancy. Low - carbohydrate diets or fats that causes ketosis deprive the foetal brain of needed glucose and may impair its development. Such diets are also likely to lack other nutrients vital to foetal growth.
Regardless of prepregnancy weight, pregnant women should never intentionally lose weight. i) Sugar substitutes Artificial sweeteners have been extensively investigated and found to be safe for use during pregnancy. (Women with phenylketonuria should not use aspartame). It would be prudent for pregnant women to use sweeteners in moderation and within an nutritious and well balanced diet.
