If you're trying to conceive, it's time to change your eating habits. You can boost your body's nutritional intake by eating healthy foods and maintaining a healthy lifestyle. Nutrient-rich foods, including fruits and vegetables, fish, oysters, plant proteins and whole grains, may help support fertility, some studies show. Limit alcohol, trans fats and caffeine. Encourage your partner to eat a healthy diet as well, as this supports healthy sperm. So what foods and nutrients do you need most to help you get pregnant? And how?
