Health care experts haven't reached a consensus on the issue of vitamin and mineral supplements. Many say that if you are healthy and eat a well-balanced diet, you don't need any. But not all of us eat a well-balanced diet. And sometimes, you may follow a nutritious diet and still be deficient. Many women fail to get the adequate amount of vitamins and minerals. Stress increases your need for vitamins and minerals, especially C, B-complex and zinc.
Studies link high sodium intake to higher blood pressure, and evidence suggests that many people at risk for high blood pressure can reduce their risk by consuming less salt or sodium, as well as following a healthy diet. Most Americans consume more sodium than they need. The recommended amount is less than 2,300 mg per day for children and adults to age 50. The limit drops to 1,500 mg per day for those 51 and older or those of any age who are African American or have hypertension, diabetes or chronic kidney disease. You get 2,300 mg in just one teaspoon of salt. One good way to reduce your sodium intake is to eat fewer prepared and packaged foods.
No matter how busy you are, eat lunch before 3 p.m., a Spanish study suggests. Researchers placed a group of women on a diet for 20 weeks; half ate lunch before 3 and half consumed their midday meal after 3. Although both groups’ daily caloric intake, time spent exercising and sleeping, and appetite hormone levels were the same, those who lunched late lost about 25 percent less weight than earlier eaters. Being European, lunch was the biggest meal of the day for these women, constituting 40 percent of their calories for the day, so consider slimming down dinner in addition to watching the clock.
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).
Rocking out to your fave playlist helps you power through a grueling workout, and now research shows singing, humming, or whistling may be just as beneficial. [Tweet this tip!] A German and Belgian study found that making music—and not just listening to it—could impact exercise performance. People who worked out on machines designed to create music based on their efforts exerted more energy (and didn't even know it) compared to others who used traditional equipment. Sweating to your own tune may help make physical activities less exhausting, researchers say.
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.
Fiber is an important part of an overall healthy eating plan. Good sources of fiber include fortified cereal, many whole-grain breads, beans, fruits (especially berries), dark green leafy vegetables, all types of squash, and nuts. Look on the Nutrition Facts label for fiber content in processed foods like cereals and breads. Use the search tool on this USDA page to find the amount of fiber in whole foods like fruits and vegetables.
Before you start a juice cleanse diet, know that drastically restricting your caloric intake to drop pounds may backfire: In a 2010 study, women placed on a 1,200-calorie diet for three weeks had elevated levels of cortisol, our primary stress hormone. [Tweet this fact!] Chronic stress has been associated with an increased risk of weight gain as well as coronary heart disease, hypertension, diabetes, cancer, and impaired immune functioning.
If you thought texting changed your love life, imagine what it could do for your waistline. When people received motivational text messages promoting exercise and healthy behaviors twice a week (i.e., “Keep in the fridge a Ziploc with washed and precut vegetables 4 quick snack. Add 1 string cheese 4 proteins”), they lost an average of about 3 percent of their body weight in 12 weeks. Participants in the Virginia Commonwealth University study also showed an improvement in eating behaviors, exercise, and nutrition self-efficacy, and reported that the texts helped them adopt these new habits. Find health-minded friends and message each other reminders, or program your phone to send yourself healthy eating tips.
