For healthy bones and teeth, women need to eat a variety of calcium-rich foods every day. Calcium keeps bones strong and helps to reduce the risk for osteoporosis, a bone disease in which the bones become weak and break easily. Some calcium-rich foods include low-fat or fat-free milk, yogurt and cheese, sardines, tofu (if made with calcium sulfate) and calcium-fortified foods including juices and cereals. Adequate amounts of vitamin D also are important, and the need for both calcium and vitamin D increases as women get older. Good sources of vitamin D include fatty fish, such as salmon, eggs and fortified foods and beverages, such as some yogurts and juices.
Choose whole foods instead of processed. Swap your frozen pizza and instant ramen with whole foods like fresh fruits, vegetables, and whole grains. They are packed with essential nutrients like protein, fiber, healthy fats, vitamins and minerals as opposed to processed foods which contain empty calories. “Commit to adding veggies to your lunch and dinner and fruit to your snack,” suggests DiCarlo.
In between meals, go ahead and have a snack. "When you go too long in between meals without eating, it is difficult to go into your next meal in control and avoid overeating,” Julia Levine Axelbaum, R.D., L.D., Bariatric Dietitian at NewStart Clinic, tells SELF. Of course, you'll want to be thoughtful about the kind of snacks you opt for. She explains that those that are high in protein, fiber, and complex carbohydrates will give you the energy you need to get through the day and keep you satiated from one meal to the next. On the other hand, those that are high in refined carbs and sugar will give you a sudden blood sugar spike that will eventually cause you to crash and feel even more tired.
Animal products, such as meat, fish and poultry are good and important sources of iron. Iron from plant sources are found in peas and beans, spinach and other green leafy vegetables, potatoes, and whole-grain and iron-fortified cereal products. The addition of even relatively small amounts of meat or foods containing vitamin C substantially increases the total amount of iron absorbed from the entire meal.
Carbohydrates should provide 45%–65% of your daily calories. Most of those calories should come from the complex carbohydrates in high-fiber and unrefined foods, such as bran cereal and other whole-grain products, brown rice, beans and other legumes, and many fruits and vegetables. These carbohydrates are digested and absorbed slowly, so they raise the blood sugar gradually and don't trigger a large release of insulin. People who eat lots of these foods have higher HDL ("good") cholesterol levels and a lower risk of obesity, diabetes, and heart disease. A good amount of soluble fiber in the diet lowers LDL ("bad") cholesterol, and high-fiber diets reduce the risk of intestinal disorders ranging from constipation and diverticulosis to hemorrhoids. Some studies have shown that fiber may help reduce the risk of colon cancer. Men need more fiber than women: 38 vs. 25 grams a day before the age of 50 and 30 vs. 21 grams a day thereafter.
