Poojs replied. Stress is not usually a factor in miscarriage. In fact, most causes of miscarriage are either unknown or beyond your control. high levels of stress can affect a baby' s health during pregnancy. high stress levels can result in premature birth and low birth weight, and even lead to allergies and asthma later in life. And pregnant women who suffer the extreme psychological stress of being in a war zone are more likely to deliver a child who develops schizophrenia. Mihika replied. Uncooked seafood and rare or undercooked beef or poultry should be avoided because of the risk of contamination. Fish that contain high levels of mercury should be avoided. Mercury consumed during pregnancy has been linked to developmental delays and brain damage. Avoid fish from contaminated lakes and rivers that may be exposed to high levels of polychlorinated biphenyls. Raw eggs or any foods that contain raw eggs should be avoided because of the potential exposure to salmonella. Imported soft cheeses may contain bacteria called Listeria, which can cause miscarriage.
