The tiny gender differences in minerals other than calcium and iron depend on body size. But while the dietary requirements for selenium fit this rule, men may benefit from supplements of about 200 micrograms a day, a level about four times above the RDA. That's because both a clinical trial and an observational study suggest that selenium may reduce the risk of prostate cancer. It's far from proven, but it's something for men to consider.
Young adults. Teen girls and young women usually need more calories than when they were younger, to support their growing and developing bodies. After about age 25, a woman’s resting metabolism (the number of calories her body needs to sustain itself at rest) goes down. To maintain a healthy weight after age 25, women need to gradually reduce their calories and increase their physical activity.
The U.S. Department of Health and Human Services declared last week National Women’s Health Week (May 14-20th), but in reality we should be taking care of ourselves and have this awareness all year round, right? To kick this month off inspired by women’s health, let’s talk about health, nutrition, and of course answer your questions from Instagram, Twitter, and email from over this year!
The average woman should get 10 to 35 percent of her daily calories from protein. Protein helps prevent muscle tissue from breaking down and repairs body tissues. Sources of animal proteins include meat, fish, poultry, eggs, milk and cheese. Vegetable proteins include dried beans and peas, peanut butter, nuts, bread and cereal. (A three-ounce serving of cooked chicken contains about 21 grams of protein.)
Calcium: Although some bone loss is inevitable with age, women can slow the process by getting enough calcium and vitamin D. Women between the ages of 50 and 70 need 1200 mg of calcium and 600 IU of Vitamin D a day. Women older than 70 require 1200 mg of calcium and 800 IU of Vitamin D a day. Because the skin becomes less efficient at converting sunlight to vitamin D as we age, older women may need more vitamin D in the form of supplements. Talk to your doctor.
Poor nutrition may be one of the easiest conditions to self-diagnose. Look at the food pyramid and the suggested servings. Look at your diet. Are you getting the recommended daily amounts of fruits and vegetables? Enough calcium? Read the labels and compare what you eat to what you need. You may discover that even if your weight is ideal, you are not getting enough nutrition.
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.
Salads can be a great source of nutrients while being low in saturated fat and simple carbohydrates. The key word is "can." Too many times I see individuals pass up perfectly healthy sandwiches and entrees, opting instead for a salad drenched in dressing, bacon bits, and croutons. These items, loaded with fat and calories while scant on nutrients, will not only sabotage a diet but will often fail to make you full.
The new guidelines encourage eating more nutrient-dense food and beverages. Many of us consume too many calories from solid fats, added sugar and refined grains. The guidelines promote a diet that emphasizes vegetables, fruits, whole grains, fat-free or low-fat dairy products, seafood, lean meat and poultry, eggs, beans and peas, and nuts and seeds.
The overall effect is a tighter, more toned physique, but body weight could stay the same or even increase. Therefore, the obsession with numbers on a scale is unfounded; one can greatly improve appearance, enhance fitness levels, and eliminate unwanted fat all while maintaining a constant weight. Focus instead on a combination of body fat measurements in trouble spots and the image in the mirror.
