It's a cliché, to be sure, but a balanced diet is the key to good nutrition and good health. Following that diet, however, isn't always that easy. One challenge is that women often feel too busy to eat healthfully, and it's often easier to pick up fast food than to prepare a healthy meal at home. But fast food is usually high in fat and calories and low in other nutrients, which can seriously affect your health. At the other extreme, a multimillion dollar industry is focused on telling women that being fit means being thin and that dieting is part of good nutrition.
Iron is one of the keys to good health and energy levels in women prior to menopause. Foods that provide iron include red meat, chicken, turkey, pork, fish, kale, spinach, beans, lentils and some fortified ready-to-eat cereals. Plant-based sources of iron are more easily absorbed by your body when eaten with vitamin C-rich foods. So eat fortified cereal with strawberries on top, spinach salad with mandarin orange slices or add tomatoes to lentil soup.
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.
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!]
A healthy vegetarian diet falls within the guidelines offered by the USDA. However, meat, fish and poultry are major sources of iron, zinc and B vitamins, so pay special attention to these nutrients. Vegans (those who eat only plant-based food) may want to consider vitamin and mineral supplements; make sure you consume sufficient quantities of protein, vitamin B12, vitamin D and calcium. You can obtain what you need from non-animal sources. For instance:
Trans fatty acids, also known as trans fats, are solid fats produced artificially by heating liquid vegetable oils in the presence of metal catalysts and hydrogen. They also pose a health risk, increasing LDL or "bad" cholesterol and increasing your risk of coronary heart disease. They are often found in cookies, crackers, icing and stick margarine, and in small amounts in meats and dairy products. Beginning in January 2006, all food manufacturers had to list the amount of trans fatty acids in foods, resulting in a significant reduction in the amount of these fats used in prepared foods. In its guidelines, the American Heart Association notes that trans fats increase risk of heart disease by raising "bad" LDL cholesterol and should be avoided as much as possible. In addition, research has shown that trans fats can also decrease "good" HDL cholesterol, increase inflammation, disrupt normal endothelial cell function and possibly interfere with the metabolism of other important fats—even more evidence that they are very bad for overall health.
There's not much doubt about this one: Women need more iron than men, because they lose iron with each menstrual period. After menopause, of course, the gap closes. The RDA of iron for premenopausal women is 18 mg a day, for men 8 mg. Men should avoid excess iron. In the presence of an abnormal gene, it can lead to harmful deposits in various organs (hemochromatosis). Since red meat is the richest dietary source of iron, it's just as well that men don't need to wolf down lots of saturated fat to get a lot of iron.
Also known as “myofascial release,” foam rolling is an easy way to benefit your entire body. “While stretching addresses the length of muscle fiber, rolling improves the quality of the tissue,” says Rob Sulaver, CEO and founder of Bandana Training. This leads to tension- and pain-free muscles, which function better so you perform better. Be sure to roll for five minutes before your workout. Not sure what to do? Try these 10 ways to use a foam roller.
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.
Native to East Asia, soybeans have been a major source of protein for people in Asia for more than 5,000 years. Soybeans are high in protein (more than any other legume) and fiber, low in carbohydrates and are nutrient-dense. Soybeans contain substances called phytoestrogens, which can significantly lower your "bad" LDL cholesterol and raise your "good" HDL cholesterol.
Obviously, the best treatment plan for poor nutrition is to change your diet. Most Americans eat too little of what they need and too much of that they don't. For many women, decreasing fat and sugar consumption and increasing fruit, vegetables and grains in your diet can make a big difference. Many women also need to boost consumption of foods containing fiber, calcium and folic acid. Compare your diet to that suggested by the food pyramid and compare your nutrient intake to the suggested daily levels. Adjust accordingly, and you may be able to dramatically improve your health.
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.
