Cut down on sugar
Around now you'll probably notice that you're gaining weight steadily - about half a pound a week. If you are overweight, don't go on a diet, but eat healthily and avoid high-fat and high-sugar foods.
You may notice that your gums bleed when you brush your teeth. Look after your teeth and keep your dental appointments. If your diet is low in added sugar - and you generally avoid cakes, sweets and biscuits - you will also reduce your risk of tooth decay.
Our bodies need vitamin A in pregnancy to help our eyes adapt to light and dark, to help our skin and tissues to grow healthily. Vitamin A comes in two forms - retinol and betacarotene. Both are needed in pregnancy but too much retinol can harm a developing baby by causing birth defects.
Good sources of retinol are egg yolk, butter or margarine and milk. Liver is very high in the retinol form of vitamin A and therefore should be avoided when you are pregnant. Good sources of betacarotene are carrots, sweet potatoes, papaya, oranges and green vegetables, especially broccoli, watercress, spinach and spring greens.
