Disease fighting foods for women

Wednesday, August 1st, 2007

It’s well known that cranberries can help protect against cystitis but there are other foods for women with disease fighting properties:

  1. Papaya. This tropical fruit packs about twice the vitamin C of an orange. After analyzing the blood of over 13,000 people, scientists from the University of California, San Francisco, found that women who had lower levels of vitamin C were more likely to have gallbladder illnesses. One medium papaya (about ten ounces), with its 188 mg of vitamin C and a mere 119 calories, is a good source of the vitamin. The once exotic fruit now can be found in most supermarkets.
  2. Flaxseed. Rich in oestrogen-like compounds called lignans which are a potential weapon against that lady killer breast cancer. You can add flaxseeds (also called linseeds) to cakes and bread, but the easiest and healthiest way to get the beneficial lignans is to sprinkle a few tablespoons of ground flaxseed on your morning cereal. Look for the seeds in health food stores or in supermarkets and buy organic ones. They’re easy to grind in a blender or coffee grinder or you can get them ready ground in a vacuum pack and then store them in the fridge. Buy the seeds if you want the lignan-effect as there are no lignans in the oil.
  3. Tofu. Foods high in soya protein can lower cholesterol and may minimize menopausal hot flushes and strengthen bone. Isoflavones, plant chemicals in soya beans that have a structure similar to oestrogen, may be the reason. A half-cup of tofu contains about 25 to 35 mg of isoflavones. Other beans like lentils, chickpeas, kidney beans etc are a good source of isoflavones too.
  4. Collard Greens. This humble vegetable may help fight osteoporosis, which afflicts many women late in life. In addition to getting adequate amounts of calcium and vitamin D, some studies suggest that vitamin K may have a bone-protective effect as well. Based on data from one of the largest studies of women, the Nurses’ Health Study, researchers discovered that women who ate enough vitamin K-rich foods (at least 109 micrograms of the vitamin daily) were 30 percent less likely to suffer a hip fracture during ten years of follow-up than women who ate less. The researchers stated that dark-green leafy vegetables — Brussels sprouts, spinach, broccoli — are all good sources of the vitamin. But collard greens, with about 375 micrograms per half-cup, are among the best.

In the News: calcium – the key to staying slim after 50

In the News: calcium helps you lose weight after 50For years, women around the menopause have been told to take calcium and vitamin D tablets to protect their bones. But researchers believe there could be another incentive – staying slim.

Women over 50 who regularly take calcium and vitamin D supplements are less likely to gain weight than those who do not, according to a study. Researchers found that those who were deficient in calcium and vitamin D got the greatest benefits. The finding comes from a seven-year study of more than 36,000 U.S. women aged 50 to 79 enrolled in the Women’s Health Initiative Study. Half the women took 1,000mg of calcium and 400 ius of vitamin D every day; the other half took placebo pills.

After the menopause, women tend to gain weight especially around the middle. The results of the study showed that calcium and vitamin D supplements slowed the weight gain — particularly among women who weren’t getting enough calcium to begin with. The important thing about this study is that by taking extra calcium and vitamin D you are not only protecting your bones but can easily prevent some of that weight gain after menopause.

Calcium seems to reduce fat absorption and increase leptin, the substance that curbs appetite. Older women are encouraged to take calcium supplements to prevent osteoporosis, so this research suggests there may be a double benefit. In addition, we’ve seen recent reports that vitamin D may play a part in preventing breast cancer and other disorders. Most good ‘bone’ supplements will contain both calcium and vitamin D so you do not have to take separate supplements of the two nutrients.

Mastering your metabolism by the decade

Sunday, July 1st, 2007

As you get older there is a steady, gradual drop in your basal metabolic rate (BMR). This drops by two per cent for every decade of your life. Therefore, over the years you may need to change what you do to stay fit slim and toned.

In your early twenties you naturally have more lean muscle and less fat, so your metabolic rate will be high. Staying in shape is also likely to be easier as the chances are you have more time to get active and to spend on yourself. Bear in mind though that by your mid-twenties, if you’re not exercising regularly – concentrated exercise, such as power walking, cycling or aerobics, say three times a week – muscle mass gradually starts to decline, slowing your metabolic rate and increasing your fat stores. It’s also crucial to make sure you eat breakfast because if you don’t, you slow down your metabolism and send the body into “hoard mode,” thinking it’s starving because you’re going a long period of time frequently 8 to 10 hours or more, without food.

The thirties, like the forties, can be a busy decade for most women jugging career and family life but extra weight tends to head for the hips on women and most of us try to work it off with running or aerobic exercise but what we really need is to do more toning – not only because toning helps you to control your shape, but crucially because toning also helps to protect against osteoporosis.

Dinner should be your lightest meal, and some experts recommend you don’t anything after 8 p.m., or any later than 3 to 4 hours before bedtime. This helps your body process and burn the food when you’re awake and moving around and burning more calories per hour. It’s also not a good idea to drop your calorie intake below 1,000 calories a day during this decade (or any decade) because this will signal to your body that you are in starvation mode, and will slow down your metabolism.

During your forties your BMR starts to slow down as hormone fluctuations occur and weight starts to settle around the stomach and waist. It is absolutely crucial during these years to do toning weight resistance exercises two to three times a week to build up your metabolism boosting muscle and to help prevent osteoporosis. Also instead of three to five aerobic sessions every week you need to do at least 30- 40 minutes of aerobic exercise a day to keep your metabolism boosted.

Smaller, more frequent meals and snacks keeps your blood sugar stable and provides a steady source of energy to fuel metabolism so don’t go for more than three hours without eating. You’ve heard it before, but drink those 8 glasses of water every day. The energy burning process of metabolism needs water to work effectively.

The average age for the onset of the menopause is 51. During the menopause the body produces less oestrogen, which can cause the rapid loss of bone density. For some women, the hormonal changes can trigger weight gain. Given that the metabolic rate continues to slow with age unless it’s speeded up by regular exercise and weight training exercises to build metabolism boosting muscle, menopause weight gain can be difficult to lose. Make sure you get some good quality muscle building protein with every meal you eat, such as eggs, fish, pulses, nuts, seeds and especially hormone balancing soya.

During the sixties and beyond, weight generally stabilises but this is the time when you need to keep a very close eye on your cholesterol levels to protect the health of your heart. Once again aerobic exercise is vital because it helps to lower high cholesterol and eating a diet naturally high in fibre, not adding bran, is also sound advice.
