In the News: The chips are down while onions go up!

Thursday, May 1st, 2008

Here’s another reason to watch your intake of chips and crisps. Eating fried food every day isn’t just bad for your waist line and your heart – it can also increase your risk of ovarian or womb cancer.

Scientists from the Maastricht University in the Netherlands believe a chemical called acrylamide, found in chips, crisps, burnt toast and grilled or barbecued meat, could be the culprit. Women with the highest amounts of acrylamide in their bodies were found to be twice as likely to have one of these cancers. All processed foods, such as chips and crisps are best avoided, but if you do decide to indulge now and again it’s best to cook chips to a golden yellow rather than a golden brown

Meanwhile a new study by the Institute of Food research has suggested that an onion a day may be all that it takes to keep heart disease at bay. Research from the Institute of Food has shown that quercetin, a compound in onions helps prevent chronic inflammation that can lead to thickening of the arteries and an increased risk of heart disease. (Quercetin can also be taken in supplement form – see the Resources Page).

Is your thyroid making you gain weight?

Thursday, May 1st, 2008

 

If you’re gaining weight without eating any more, feeling tired, get constipated a lot, suffer from dry skin and feel cold most of the time even when it’s a warm day, you could have an under active thyroid (hypothyroidism). Around 1 in 50 women develop an under active thyroid and it tends to be most common in women aged over 40.

The thyroid gland situated in your neck, helps control your metabolism which in turn controls your weight. Your thyroid produces a number of hormones, the most important being thyroxine (also called T4).   Thyroxine, an inactive hormone, becomes activated when converted to triidothyronine (called T3).  Your thyroid gland is like a thermostat that regulates your body temperature and tells your body to burn calories and use energy. It is the T3 hormone that makes the metabolism work faster and burn fat.  An underactive thyroid may be caused by one of two things: either your pituitary gland is not producing enough thyroid-stimulating hormone (TSH) or your thyroid is not working properly. 

 

How can you tell if your thyroid isn’t working properly?

 

If you answer ‘yes’ to four or more of the following questions, your thyroid gland could be underactive. Ask your doctor for a blood test, which can establish how well your thyroid is functioning.

 

  • Has your weight gone up gradually over months for no apparent reason?
  • Do you often feel cold?
  • Are you constipated?
  • Are you depressed, forgetful or confused?
  • Are you losing hair or is it drier than it used to be?
  • Are you having menstrual problems?
  • Are you having difficulty getting pregnant?
  • Have you noticed a lack of energy?
  • Are you getting headaches?

 

If a blood test does not show that you have an under active thyroid, you may only have a mild problem, which could go undetected in a blood test. In most cases healthy diet and lifestyle changes (see below) will get your thyroid back on track.

 

The other way to test whether you have low thyroid function is to measure your temperature. If your temperature is too low, it may indicate that you have a sluggish metabolism caused by an underactive thyroid. Aim to take your temperature once a day for three days. If you have periods you should take your temperature on the second, third and fourth days of your cycle. A woman’s body temperature rises after ovulation so it would not give a clear picture if done later in the cycle. If you are not menstruating, take your temperature on any three consecutive days.

 

Put a thermometer by your bed before you go to sleep (a mercury thermometer is fine but there are some good electronic ones on the market). When you wake, lie still in bed and take your temperature before drinking or visiting the bathroom. Put the thermometer in your armpit and leave it until it bleeps. If you are using a mercury thermometer, leave it for 10 minutes. If your average temperature over the three days falls below 36.4ºC (97.6ºF), your thyroid may be under functioning and you should consult your doctor or health professional immediately.

 

The thyroid diet

 

As with so many conditions concerning hormonal imbalance the first line of treatment is dietary. While no diet works for everyone, the same is true with a thyroid-supportive diet. In general, however, the better the quality of your diet, the healthier your thyroid gland will be, as well as every other gland, organ and cell within your body. More specific dietary recommendations are outlined below.

 

Unhelpful Foods

You don’t need to cut them out of your diet completely but foods to eat LESS of as they may interfere with thyroid function are: cabbage, kale, broccoli, kohlrabi, mustard, lima beans, sweet potato, peanuts, and soya products, so keep these to a minimum. These foods are called goitrogens which means they can block the uptake of iodine (see below) and make thyroid problems worse. These foods only seem to be a problem when they are raw and eaten excessively, so make sure they are cooked well and eat in moderation.

 

Avoid Stimulants

A diet that is heavy on the consumption of alcohol, caffeine and sugar will over-stimulate the thyroid, and this overwork leads to the thyroid eventually being unable to fulfil its function. Cutting back on sugary foods and drinks, limiting or eliminating alcohol and caffeine and eating a healthier balanced diet will give your thyroid the break it needs to rejuvenate and start working properly.

 

Protein

Since it takes more energy to break down protein than carbohydrate and fat, it is easy to see that your metabolic rate increases in relation to protein intake. Hence, a healthy thyroid diet entails eating good sources of such as fish, legumes, egg, nuts and seeds.  An adequate intake of protein will also deter the hair loss that often accompanies an underactive thyroid condition.

 

Fibre

The recommended daily amount of fibre is 25 grams a day. Since fibre slows down the rate at which food, including simple carbohydrates, is digested, getting this quota is important for keeping insulin production in check when incorporating a thyroid-friendly diet into your lifestyle. High fibre foods include lentils, kidney beans, apples, pears, broccoli, cauliflower, green leafy vegetables, whole grains (which naturally contain bran rather than adding in refined bran), almonds, and flaxseed (linseed) to name a few.

 

Supplements

In general, a multivitamin and mineral is essential in the thyroid diet (choose one that is appropriate for your age, if you are over 45 then MenoPlus is a good one, see the Resources page) but the following specific nutrients also help optimise healthy thyroid function.

 

Iodine

This mineral is a necessary component of T3 and T4. Iodine combines with the amino acid tyrosine and gets converted into the two thyroid hormones. For this reason, getting sufficient amounts of iodine through fish, seaweed and shellfish is critical for the optimal function of the thyroid. It is well documented that a diet low in iodine is associated with hypothyroidism or under-active thyroid. The best supply of iodine is from sea salt and seaweed. In Japan, for instance, the daily intake of iodine from seaweeds is estimated to average 3mg per day and thyroid disorders are known to be extremely rare.

 

Herbalists have traditionally used bladderwrack which is a sea weed rich in iodine to help with under active thyroid. Some studies show that a combination of iodine and vitamin E is most effective in boosting thyroid function.  If you take too much iodine you can actually make an under-active thyroid condition worse.  I would recommend that you see a qualified practitioner to help with thyroid problems.

 

Selenium

Increasing your intake of selenium has also been shown to boost thyroid function as selenium; along with zinc are both essential for the prevention of diminishing T3 hormone levels. T3, remember, is the active thyroid hormone which burns fat. If your T3 levels are low, your metabolism inevitably slows down. You can boost your intake of selenium by eating foods such as whole wheat bread, brazil nuts, tuna, onions, tomatoes and broccoli. Include some of these foods on a regular basis in your diet.

 

Zinc

One study in Italy revealed that supplementing the diet with zinc improves thyroid function. Many patients with hypothyroidism have low levels of zinc, and the study demonstrated that over 50% of patients given zinc supplementation experienced improved thyroid function which reduced the incidence of clinical hypothyroidism.

 

Hypothyroidism and Toxic Materials

Preliminary studies have found an association between multiple chemical sensitivities and hypothyroidism. One study found a correlation between high blood levels of lead, a toxic heavy metal, and low thyroid hormone levels in people working in a brass foundry. Many of these people also complained of depression, fatigue, constipation, and poor memory (symptoms of hypothyroidism). Occupational exposure to other chemicals has also been associated with decreased thyroid function

 

Exercise

Physical activity is especially important if you suffer from an under-active thyroid because it can help speed up your metabolism and boost weight loss. A daily 30 minutes of brisk walking, building up to 45 minutes is fine. If you currently take regular exercise, it will help to increase what you do by just 10 minutes extra per day.

 

Reduce Stress

Stress is thought to be a contributing factor to the development of hypothyroidism. This is because high cortisol levels released when you are stressed reduce levels of the thyroid hormone T3.  Added to this, high levels of cortisol will urge your body to break down muscle to provide glucose for your brain and the less muscle you have the slower your metabolism will be. Stress management techniques such as breathing, meditation and yoga are all recommended. Another great way to reduce stress is to take regular exercise. Taking regular time out is also crucial.

 

Master of your metabolism

Remember, the thyroid hormone is the master metabolism hormone. And even if your thyroid is functioning healthily eating a healthy diet and exercising regularly can help keep it healthy and functioning optimally.

 

If your thyroid is out of balance, your metabolism is out of balance too and this will make any attempt at weight loss tough. You may be prescribed medication by your doctor, and this can work alongside your new eating habits to help resolve your difficulties. However, in my experience, even while on medication, weight loss is slower than normal, so it is VERY important to stick closely to a healthy eating plan AND take regular exercise.

 

Whether or not you have a thyroid problem it is important to eat healthily, exercise regularly and ease up on stress to keep the thyroid working as well as possible to keep your weight under control, and help you feel better.

Can you prevent stretch marks naturally?

Thursday, May 1st, 2008

Stretch marks appear when the tissue under the skins expands faster than the skin itself. This will cause tiny tears in the skin. Stretch marks are basically scars that form to protect the skin.

 

One obvious reason for getting stretch marks is weight gain and as women tend to gain the most weight during pregnant stretch marks are often inevitable when you’ve had your baby. Losing a lot of weight can also cause stretch marks as well, so if you are losing weight, you have to use a solution in order to prevent it from occurring.

 

How can you prevent stretch marks if you are pregnant or if you have gained a lot of weight and are now losing it?

 

The first thing is to pinpoint the areas where a person can have stretch marks. Pregnant women typically have stretch marks on their hips, bellies and breasts. People who are losing and gaining weight can have stretch marks on the part where they gained or lost weight. Identifying the areas is very important so you would know which areas to prevent stretch marks.

 

If you’re having a baby gaining no more than the recommended amount of weight and gaining it slowly may help reduce your chances of getting them. Rapid or excessive weight gain will only compound the problem of stretch marks and likely cause you to have more in the end. The same rule applies if you are losing weight; keep your weight loss slow and steady, say no more than 1 or 2 pounds a week, as this will decrease your risk of stretch marks.

 

Keeping your skin well-moisturised may help prevent stretch marks. A nourishing lotion, oil or cream applied on a daily and nightly basis will moisturise your skin (and also reduce itching!) There are many products especially for stretch mark prevention that contain ingredients such as vitamin E, vitamin A, emu oil, cocoa butter, wheat germ oil. Certainly moisturising helps to improve the skin’s elasticity, however, do bear in mind that the effectiveness of these products in preventing stretch marks have been shown to be rather limited.

 

A sensible diet containing plenty of fruits, vegetables and leafy greens is a must. Excellent nutrition also contributes to the strength and health of your skin. Eating foods such as those high in vitamins C, found in fruits and vegetables and vitamin E found in nuts and seeds, zinc, found in pumpkin seeds and silica, found in soybeans, will help your skin to stretch better and also help your skin to bounce back quicker after giving birth. Drinking plenty of water and taking your prenatal vitamins (like Ante Natal Plus – see the Resources Page) or a daily multi vitamin and mineral if you aren’t expecting are also critical for beautiful skin.

 

Laser treatments may be beneficial and are rapidly gaining in popularity. Using a laser or intense light, stretch marks are treated by flashes or beams of laser light that pass through the skin into the collagen within the second layer of skin. These treatments are quick, with little recovery time involved. Cosmetic surgery is another option, but is used as a last resort- for the most severe scarring from stretch marks. Unfortunately, these kinds of procedures are expensive.

 

The bad news is that stretch marks are permanent and very rarely disappear. The good news is that stretch marks usually become considerably less noticeable over time (naturally), eventually becoming a few shades lighter than your natural skin tone and the best way to help that natural process along is to lose weight slowly and steadily, to eat healthy, drink plenty of water and exercise regularly.
