Dietary fiber is found in plant foods like whole-grain breads and cereals, beans and peas, and other vegetables and fruits. At least one study suggests that women who eat high amounts of fiber (especially in cereal) may have a lower risk for heart disease. High-fiber intake is also associated with lower cholesterol, reduced cancer risk and improved bowel function. And one long-term study found that middle-aged women with a high dietary fiber intake gained less weight over time than women who ate more refined carbohydrates, like white bread and pasta.
A BMI of 25 to 29.9 is considered overweight and one 30 or above is considered obese. For an idea of what this means, a 5-foot 5-inch woman who weighs 150 pounds is overweight with a BMI of 25. At 180 pounds, she would be considered obese, with a BMI of 30. Keep in mind that the tables aren't always accurate, especially if you have a high muscle mass; are pregnant, nursing, frail or elderly; or if you are a teenager (i.e., still growing).
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.
Foods that contain natural folic acid include orange juice, green leafy vegetables, peas, peanuts and beans. (One cup of cooked kidney beans contains 230 mcg of folic acid.) Fortified foods, such as ready-to-eat breakfast cereals, also contain a synthetic form of folic acid, which is more easily absorbed by your body than the natural form. Folic acid is now added to all enriched grain products (thiamin, riboflavin, niacin, and iron have been added to enriched grains for many years).
Fluids: Fluid needs increase as women age. The reason: Kidneys become less efficient at removing toxins. “Drinking more fluids helps kidneys do their job,” Schwartz says. “Unfortunately, thirst signals often become impaired with age, so people are less likely to drink enough water and other fluids.” Rather than fret about how many glasses to drink, Frechman says, check the color of your urine. "It should be clear or very pale colored. If it becomes darker, you need more fluid.”
Nutrition-sensitive approaches are difficult to link to women's nutritional status (5, 102). This is due to limited measurement of benefits to program beneficiaries, families, households, and communities, limited timeframes to evaluate long-term impact, logistical and political realities that make implementation difficult, and different priorities of different stakeholders in multisectoral programs (102). Many nutrition-sensitive approaches, as will be described, thus focus on more distal measures of impact (e.g., coverage, knowledge) and not more proximal measures of women's nutritional status (e.g., BMI, anemia status, etc.).
The daily calcium recommendations are 1,000 milligrams a day for women under 50, and 1,500 milligrams a day for women 51 and older. Oddly enough, these are the same requirements for men, who are much less prone to osteoporosis than women. But the recommendation takes into account the fact that women are smaller than men. Thus the amount of daily calcium is greater for women on a proportional basis.
The best training tool you're not using: a jump rope. “It may seem a little juvenile until you think of all the hot-bodied boxing pros who jump rope every single day,” says Landon LaRue, a CrossFit level-one trainer at Reebok CrossFit LAB in L.A. Not only is it inexpensive, portable, and easy to use almost anywhere, you’ll burn about 200 calories in 20 minutes and boost your cardiovascular health while toning, he adds.
When layering for an outdoor activity this winter, consider a compression fabric for your base layers. “These fabrics are fantastic at wicking moisture from the body, which allows you to sweat and breath while keeping you warm,” says Chiplin, who notes they can also reduce fatigue and muscle soreness so you’re ready to head out again tomorrow. Consider throwing them in the dryer for a minute before dressing to further chase away the morning chill.
Grains, vegetables and fruits are essential to getting the vitamins, minerals, complex carbohydrates (starch and dietary fiber) and other nutrients you need to sustain good health. Some of these nutrients may even reduce your risk of certain kinds of cancer. But experts say we rarely eat enough of these foods. To make matters worse, we also eat too much of unhealthy types of food, including fat (and cholesterol), sugar and salt.
In addition to diet, exercise and other lifestyle factors can also play an important role in bone health. Smoking and drinking too much alcohol can increase your chances of developing osteoporosis, while weight-bearing exercise (such as walking, dancing, yoga, or lifting weights) can lower your risk. Strength or resistance training—using machines, free weights, elastic bands, or your own body weight—can be especially effective in helping to prevent loss of bone mass as you age.
