Popular belief says if you really want to make a big change, focus on one new healthy habit at a time. But Stanford University School of Medicine researchers say working on your diet and fitness simultaneously may put the odds of reaching both goals more in your favor. They followed four groups of people: The first zoned in on their diets before adding exercise months later, the second did the opposite, the third focused on both at once, and the last made no changes. Those who doubled up were most likely to work out 150 minutes a week and get up to nine servings of fruits and veggies daily while keeping their calories from saturated fat at 10 percent or less of their total intake.
The best evidence that ALA can protect the heart comes from the Lyon Diet Heart Study, a randomized clinical trial in Europe. It tested the effects of an ALA-enriched Mediterranean diet in 605 patients with coronary artery disease. Over a four-year period, the high-ALA diet produced a 72% reduction in heart attacks and cardiac deaths and a 56% lower risk of dying from any cause (including cancer). The Mediterranean diet differed from the standard Western diet in many respects, but because it contained a special canola oil margarine, the greatest difference was in its ALA content, which was nearly eight times higher in the protective diet.
Although canola oil appears to be good for the cardiovascular system, two Harvard studies have raised concerns that ALA might be bad for the prostate. In 1993, the Health Professionals Follow-up Study of 47,781 men published a major evaluation of dietary fat and prostate cancer. It found that saturated fat from animal sources such as red meat and whole-fat dairy products was linked to a 2.6-fold increase in prostate cancer. But the study also provided some disquieting news about ALA: Men who consumed the most ALA were 3.4 times more likely to be diagnosed with prostate cancer than those who had the lowest dietary intake.
Women have many unique health concerns — menstrual cycles, pregnancy, birth control, menopause — and that's just the beginning. A number of health issues affect only women and others are more common in women. What's more, men and women may have the same condition, but different symptoms. Many diseases affect women differently and may even require distinct treatment.
Calcium: “Getting enough calcium is important for all ages, but it's particularly important during adolescence and early adulthood, when bones are absorbing calcium,” says Heather Schwartz, MS, RD, a medical nutrition therapist at Stanford University Hospital and Clinics. Calcium and vitamin D are often paired in fortified foods such as milk. The reason: The body needs D in order to absorb calcium.
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.
If you usually head to the gym after work, take heed: Mental exhaustion can make you feel physically exhausted, even when you have plenty of energy, reports a Medicine & Science in Sports & Exercise study. When people played a brain-draining computer game before exercising, they reported a subsequent workout as being harder, yet their muscles showed the same activity as they did doing the same workout after an easy mental game. So if you think you can’t eke out those last 10 minutes on the rowing machine, remember: You can! [Tweet this motivation!]
If you’re not lifting weights already… what are you waiting for? Let me start by answering a question I get all the time — no, lifting weights isn’t just for men, everyone can reap the benefits of muscle growth. Lifting weights stimulates your lean body mass (i.e. muscle) to strengthen you from within and helps maintain healthy bone density (as mentioned earlier). Having more lean body mass – versus more fat mass – provides us with the strength we need to carry out our daily tasks, supports our core and spine, supports hormonal and bone health, AND allows our bodies to burn more calories and burn fat even while sitting. Resistance training can help decrease risks for osteoporosis, heart disease, type 2 diabetes, depression, obesity, aches and pains, and lastly arthritis. It also helps us mentally since weight training and working out, in general, makes us feel good thanks to all those endorphins that are released when your workout. You also get the added benefit of helping our metabolism, getting stronger, building muscle, and decreasing body fat when paired with well-balanced nutrition!
Sugar is a source of calories, not nutrients. Consuming too much sugar can lead to weight gain and tooth decay. Contrary to what many people think, there is no evidence linking high-sugar diets to hyperactivity or diabetes. However, high-fructose corn syrup, found in most processed foods, is linked with obesity, and obesity increases your risk for developing diabetes and other conditions.
Calcium: For adult women aged 19-50, the USDA recommended daily allowance is 1,000 mg/day. For women over 50, the recommended daily allowance is 1,200 mg/day. Good sources of calcium include dairy products, leafy green vegetables, certain fish, grains, tofu, cabbage, and summer squash. Your body cannot take in more than 500 mg at any one time and there’s no benefit to exceeding the recommended daily amount.
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:
Oils. When cooking try to use oils from plants instead of solid fats like butter, margarine, or coconut oil. See this list of oils and fats to see how healthy each type of cooking oil and solid fat is. Most women eat too much solid fat through packaged foods like chips or salad dressing, and not enough healthy fats like olive oil or the type of fat in seafood.
