Omega-3s: These essential fatty acids, EPA and DHA, play many roles in the body, including building healthy brain and nerve cells. Some studies show that omega-3s, especially DHA, can help prevent preterm births. Even women who don't plan to have children should be sure to get plenty of omega-3s. These healthy oils have been shown to reduce the risk of heart disease, the number one killer of women.
Weighing yourself too often can cause you to obsess over every pound. Penner recommends stepping on the scale or putting on a pair of well-fitting (i.e. not a size too small) pants once a week. “Both can be used as an early warning system for preventing weight gain, and the pants may be a better way to gauge if those workouts are helping you tone up and slim down.” [Tweet this tip!]
It doesn't matter how many pushups you can do in a minute if you're not doing a single one correctly. “There is no point in performing any exercise without proper form,” says Stokes, who recommends thinking in terms of progression: Perfect your technique, then later add weight and/or speed. This is especially important if your workout calls for performing “as many reps as possible” during a set amount of time. Choose quality over quantity, and you can stay injury-free.
If you do decide to diet, you still need to maintain good nutrition. You want to cut back on calories, not nutrients. And while you want to reduce fat, don't eliminate it entirely. Some studies suggest that older women who maintain a higher body-fat percentage are less likely to suffer from osteoporosis and other conditions associated with menopause. Fat cells also retain estrogen, which helps maintain the calcium in your bones. Younger women should be careful, too: a low body fat percentage can lead to infertility; below 17 percent may lead to missed periods, also known as amenorrhea.
When women reach childbearing age, they need to eat enough folate (or folic acid) to help decrease the risk of birth defects. The requirement for women who are not pregnant is 400 micrograms (mcg) per day. Including adequate amounts of foods that naturally contain folate, such as citrus fruits, leafy greens, beans and peas will help increase your intake of this B vitamin. There also are many foods that are fortified with folic acid, such as breakfast cereals, some rices and breads. Eating a variety of foods is recommended to help meet nutrient needs, but a dietary supplement with folic acid also may be necessary. This is especially true for women who are pregnant or breast-feeding, since their daily need for folate is higher, 600 mcg and 500 mcg per day, respectively. Be sure to check with your physician or a registered dietitian nutritionist before taking any supplements., .
For a strong backside that will turn heads wherever you go, Marta Montenegro, a Miami-based exercise physiologist and strength and conditioning coach, recommends completing 100 kettlebell swings nonstop with a moderate weight at the end of a legs workout. [Tweet this tip!] If you can’t access a kettlebell, do deadlifts and hip-thrusters instead. “Women tend to overemphasize the quadriceps even when they think they are working the butt. With these two exercises, you'll have no problem engaging the glutes and posterior muscles of the legs,” Montenegro says.
Getting enough water also is important. Many experts recommend at least eight 8-ounce glasses of water daily—more if you exercise frequently or are exposed to extremes of heat and cold. The 2010 Dietary Guidelines for Americans emphasize drinking more water and other calorie-free beverages, along with fat-free or low-fat milk and 100 percent fruit juices, instead of calorie-packed regular sodas.
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.
The U.S. Public Health Service recommends that all women of childbearing age consume 400 mcg of folic acid (a B vitamin) daily to reduce their risk of having a pregnancy affected with spina bifida or other neural-tube defects. Women who are actively trying to get pregnant should consume 600 mcg, and lactating women should consumer 500 mcg. Women of childbearing age should also take care to meet the daily requirements for calcium, fiber, iron, protein and vitamin D. Discuss supplements with a health care professional, however. Iron and vitamin D in particular can be dangerous in high amounts.
Women who have very low levels of sunlight exposure or have naturally very dark skin are at risk of vitamin D deficiency. Those affected may include women who cover most of their body when outdoors, shift workers, those who are unable to regularly get out of their house or women in residential care. Women who have certain medical conditions or are on some medications may also be affected.
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.”
Having the proper footwear is essential for any workout, and for winter runs, that means sneaks with EVA (ethylene vinyl acetate), says Polly de Mille, an exercise physiologist who oversees New York Road Runner's Learning Series for first-time New York City Marathon runners. “Polyurethane tends to get really stiff and cold in the winter, which could increase your risk of injury.” Another important feature is a waterproof and windproof upper: Look for shoes made with Gortex, or wrap your mesh uppers in duct tape to keep feet dry and warm.
A year later, a second Harvard study added to the concern. The Physicians' Health Study of 20,885 men did not evaluate diet per se, but it did measure the blood levels of ALA in 120 men who developed prostate cancer and compared them with the levels in 120 men who remained free of the disease. Men with moderately high ALA blood levels were 3.4 times more likely to develop prostate cancer than men with the lowest levels; curiously, though, men with the very highest levels were only 2 times more likely to get the disease.
