Avoid coffee, alcohol, coke, diet coke, raw eggs or half cooked egg, raw fish, smoked fish. Limit your fish intake especially in first trimester because high content of mercury in certain fish can harm the baby. Also avoid mouldy ripened, soft cheeses such as brie and camembert but cottage cheese mozzarella, feta, paneer, goat and ricotta are safe. Cold cuts like salami are not cooked and therefore should be avoided. Goes without saying that alcoholic beverages should be avoided! Spicy food and chillis in first trimester can exaggerate your morning sickness so best to avoid..
