All youth need calcium to build peak (maximum) bone mass during their early years of life. Low calcium intake is one important factor in the development of osteoporosis, a disease in which bone density decreases and leads to weak bones and future fractures. Women have a greater risk than men of developing osteoporosis. During adolescence and early adulthood, women should include good food sources of calcium in their diets This is when bone growth is occurring and calcium is being deposited into the bone. This occurs in women until they are 30 to 35 years of age. Women 25 to 50 years of age should have 1,000 mg of calcium each day, while women near or past menopause should have 1,200 mg of calcium daily if they are taking estrogen replacement therapy; otherwise, 1,500 mg per day is recommended. Women older than 65 years of age should have 1,500 mg per day.
Women have many unique health concerns — menstrual cycles, pregnancy, birth control, menopause — and that's just the beginning. A number of health issues affect only women and others are more common in women. What's more, men and women may have the same condition, but different symptoms. Many diseases affect women differently and may even require distinct treatment.
As the science of nutrition continually evolves, researchers recognize that nutrients needed to maintain a healthy lifestyle must be tailored to the individual for maximum effectiveness. Recognizing that people are not all alike and that one size does not fit all when it comes to planning and achieving a healthful diet, the Institute of Medicine's dietary guidelines, titled "Dietary Reference Intakes for Macronutrients," stress the importance of balancing diet with exercise and recommends total calories based on an individual's height, weight and gender for each of four different levels of physical activity.
Actually, more people suffer from food intolerances, which don't involve the immune system. However, food intolerance symptoms—such as intestinal distress—may mimic those of a food allergy. If you have a food intolerance, talk to a nutritionist about diagnosis and treatment; if you have food allergies, you need to see an allergist. Whether you have food allergies or intolerance, you will need to develop a diet that fits your needs and avoids foods that trigger a reaction.
It takes a lot of discipline to turn down a cupcake or roll out of your warm bed for a cold morning run. To make staying on track easier, it's important to make a real connection with your motivation, says Tara Gidus, R.D., co-host of Emotional Mojo. So think less about fitting into your skinny jeans or spring break bikini and more about emotional ties to the people you love. “Your relationships will grow stronger when you are physically healthy and taking care of yourself,” she says.
Even if you are the most independent exerciser around, give a group fitness class a shot at least once a week—you may find that you enjoy it more than sweating solo. “Happiness and health are shared through social connectedness and closeness,” says Greg Chertok, director of sport psychology at the Physical Medicine and Rehabilitation Center in New Jersey. “Geography and proximity are predictors of how contagious emotions can be, and this may translate into an athletic environment too.” Sign up for Bikram, CrossFit, spin, or Zumba, and you could find yourself—gasp!—smiling at the gym thanks to your classmates.
“The reason most people don't see changes isn't because they don't work hard—it's because they don't make their workouts harder,” says Adam Bornstein, founder of Born Fitness. His suggestion: Create a challenge every time you exercise. “Use a little more weight, rest five to 10 seconds less between sets, add a few more reps, or do another set. Incorporating these small variations into your routine is a recipe for change,” he says.
