Think Z’s for winter protection

I am not talking about catching up on your sleep, though winter is the time for slowing down and even hibernating if you are a bear! Z is for zinc and although perhaps it’s best known, and most popular effect is on the sex drive, it is also essential for supporting the immune system.

Many people get shots for flu or pneumonia with the onset of winter, but their effectiveness is reduced if you don’t have a strong immune system to help support their benefits. It’s a bit like swallowing vitamins to help your health,but not eating regularly or well – they will not do the job on their own. The truth is that once you get over the age of 55, you are likely to have a zinc deficiency and this leads to a greater susceptibility to infections, and increased oxidative stress. The good news is that this is easily reversed by taking a zinc supplement for just one year. The suggested dose is 45mg daily and a US study that showed that just that amount reduced the incidence of infections and inflammation. Speaking specifically about pneumonia, there is a new study from the Research Center on Aging at Tufts University in the US that looked at residents in Nursing homes in Boston. Half the residents were given a placebo, and half given daily supplements of vitamins, including zinc. The trial lasted a year and at the end of it everyone was given a blood test to check their zinc levels. Interestingly the trial only gave people half the recommended dietary allowance, and yet those who received the supplements and had nearly normal zinc levels had less incidence and duration of pneumonia, together with less use of antibiotics. Of those who were given antibiotics, the patients with low blood levels of zinc needed greater amounts than those with reasonable zinc levels.

The researchers were very clear that taking zinc supplements could help the over 55′s to reduce the frequency and serious effects of attacks of pneumonia – which can be fatal in vulnerable patients.

Although the US study suggested 45mg a day for supplementation, the RDA (recommended daily allowance) is just 11 mg for men and 8 mg for women. Many nutritionists consider the RDA to be far too low but you might want to start with that and gradually increase the amount – or talk it over with your doctor if you are concerned.

Need more reasons to up your zinc levels? As well as helping protect your immune system zinc is an antioxidant and anti-inflammatory, protects your eyes from age-related macular degeneration and it inhibits the abnormal blood clotting that contributes to heart disease. Don’t like supplements? Make a point of adding zinc-rich foods to your daily diet such as red meat, poultry, beans, nuts, whole grains, and dairy products. Two of the best sources are oysters and cabbage, though not at the same time if you have any respect for your taste buds!

Women smokers at greater risk for heart attacks

Traditionally women have enjoyed a natural shield against a major cardiac event such as a heart attack. Being a woman has ensured a huge nine year barrier before women become more prone to heart disease, but now a new finding has been reported by the American Heart Association. A study of more than 7,000 men and women undertaken at Johns Hopkins University in Baltimore has found that women who smoke eliminate that beneficial barrier and their risk of a heart attack is exactly the same as a man’s.

In real terms, this means that up to now, women who do not smoke would not normally present with heart problems until on average around the age of 71 but women smokers are being seen with heart problems at around the age of 62. That is a loss of nine years, but if you need an even greater incentive to give up – or persuade the woman in your life to do so = then the researchers also found that if a woman quits smoking for at least six months, her risk factors for heart attacks reverts to average.

Interestingly, the analysis of men showed virtually the same, although men only lost 3.8 years because of smoking. Men who didn’t smoke tended to show up with a heart attack at age 61; men who smoked showed up at the emergency room when they were 57.

A final cheery note from the director of the New York University Women’s Health Program. “Smoking among women causes heart attacks, lung disease, and wrinkles so this study is just another reason for women to quit or never start. It takes nine years off your life.”

Three minutes a day for a better back

Suffering from back pain and poor posture is sadly all too frequent these days. We spend a lot of time sitting for long periods, whether at a computer or in front of a television and what our back needs is gentle and regular stretching and exercise.

Visiting a chiropracter is essential for serious or chronic back problems, but if you want a simple, preventive routine then the British Chiropractic Association have devised a three minute daily stretching routine that will improve your posture and strengthen your spine. The exercises have delightful names like Twirling Star, Humming Bird and Butterfly – or if you are feeling a little more warrior-like there is also Extending the Sword and Tightrope.

They also offer you some good advice, like checking the weight of your bag or briefcase and dumping any unnecessary items out and implementing the ten minute rule – if it takes less than that to walk, then do so and leave the car at home.

To get your copy call the British Chiropractic Association on 0118 950 5950 or download a copy straight from the web, it’s only a couple of A4 pages at www.straightenupuk.org and click on the downloads link. There are two leaflets, one for adults and one for children, just click on the one you want, print it out and off you go on your way to a healthier back.

Is organic always worth it?

The sales of organic food has rocketed with our increasing concern about the effects of herbicides, pesticides and pollution. However, it can be an expensive alternative and recent research has shown that for some foods it is worth paying the difference, but not for others. Here’s how it checks out:

- Organic whole milk was shown to contain 68% more beneficial omega 3 fatty acids in one UK study

- Potatoes and Green Beans both have a much higher vitamin C content than their non-organic equivalent

- Peaches contain more nutrients in terms of their vitamin content when organically grown

- Kiwi fruit studied by the University of California scientists were revealed to have 17% more cancer-busting polyphenols and 14% more vitamin C than non-organic fruit

BUT if bananas are your favourite fruit, don’t waste your money buying organic as one study found that the fruit was so well protected by its thick skin from the 50 or more chemicals routinely used during growing and storage that virtually no trace was found of them in the fruit itself.

Natural remedy for cold sores

Lemon Balm is best known for its calming properties, and has been used for centuries as a mild form of tranquilliser, (a sort of medieval form of Valium if you like), and it has properties that inhibit bacteria and viruses. It now appears that it can also help you with one of winter’s biggest bugbears, cold sores. A study carried out in Germany at the University of Heidelberg has found that the plant contains a naturally occurring ingredient that actually stops the herpes virus from getting into the skin cells. If you are prone to this unpleasant and unsightly condition, then get a natural lip balm from the health store that contains the herb, or make a daily cup of lemon balm tea part of your winter regime – it makes a very refreshing herbal tea and would be a very calming start, or end, to the day – certainly a bit healthier than coffee!

High blood pressure in pregnancy may pose long-term risk

High blood pressure is closely monitored during pregnancy but there is new evidence from a study at the Mayo Clinic in the USA that it is an under-recognized risk factor for cardiovascular disease. Compared with women who have had normal blood pressure throughout their pregnancies, those who had high blood pressure are at greater risk of heart disease later in life. One reason could be that having high blood pressure in pregnancy has some of the same risk factors for cardiovascular disease such as diabetes or obesity. Another theory is that hypertension in pregnancy could induce long-term metabolic and vascular abnormalities that might increase the overall risk of heart disease later in life. Anyone with a family history of heart disease is well advised to have their blood pressure very closely monitored during pregnancy.

Probiotics strengthen immune system

Probiotics are living microorganisms, usually lactic acid bacteria, that help maintain the natural balance of the intestines especially after a period of taking antibiotics which can seriously disrupt that balance. Now it appears they can also help to strengthen the immune system and reduce the effect of allergies. A quick look in the chiller cabinet in the supermarket will show you that ‘probiotics’ are listed on the labels of products like drinks and yoghurts, though as these often contain sugar it might be better to take a plain acidopholus supplement or add in foods that contain probiotics such as plain, live, yoghurt and aged cheeses.

China has longevity licked

Generally speaking, you would think China would be an unhealthy place to live given all the bad press they have received about their lack of food standards, dangerous lead-laced toys, environmental abuses, exorbitant pollution, and widespread poverty. However, there are two surprising facts that have emerged recently: China boasts a life expectancy surprisingly close to that of the United States and perhaps not surprisingly they do this by spending a lot less money.

The US life expectancy is about 78 years, compared to China’s of 73 years overall, though it rises to around 80 years in cities like Beijing and Shanghai and Hong Kong is out in front with over 82 years. What do the Chinese pay for these extra years of life? Just $277 a head on healthcare in a year, compared to the United States where it is a staggering $6,100 a head each year.

The Chinese are great smokers, live with the many health hazards inherent with living in hugely over-crowded cities and in one of the most polluted countries on earth. So what is their secret? Well it is very simple and down to the fact that daily exercise is widespread and woven into the Chinese culture, offering more than just a way to burn calories. It also enforces social interaction, limiting the isolation that so often comes with old age in the West. Any visitor to China is struck by the way masses of people can be seen practicing tai-chi, aerobics, games, and even open air ballroom dancing. Every day exercise is vital for health and longevity and if you want to try something different from your usual morning or evening walk, then studies have pinpointed several benefits of Tai Chi, as it stimulates your central nervous system, lowers your blood pressure, relieves stress, tones muscles and helps with digestion and waste elimination.

Chlamydia and male fertility

Chlamydia is a sexually transmitted infection caused by the bacterium chlamydia trachomatis. In the UK, the number of new diagnoses has been steadily increasing each year since the mid-1990s, and it has now become the most commonly diagnosed STI.

There has been much publicity about the devastating effects of chlamydia on fertility in women, where, if left untreated, it can affect the uterus, ovaries and fallopian tubes. It is estimated that sexually active women aged under-25, have a 1 in 10 chance of getting chlamydia but scientists from Spain and Mexico have now established that it presents similar risks for men.

They have estimated that men who are aged between 20 and 30 are most at risk of becoming infected and that it can make men infertile by damaging the quality of their sperm. As chlamydia often has no symptoms, in both men and women, it can often go undiagnosed, but is easily treatable in the early stages. It is when it is well established that damage can occur so prevention is the best plan by always using condoms and having regular checkups. STI clinics can perform a simple urine test, or there are also home testing kits available.

Natural tips for weight loss

Quick fix diets are just that – quick, but not necessarily healthy. Do you think eating salad will help? Well, it could but you would do better apparently by switching it for a nutritious soup before your main course. Medical researchers in Texas found that by giving their volunteers a bowl of a high-fat soup then sending them off to a pizza buffet – only in America would that be in a diet trial – the participants followed it by eating considerably smaller portions, and fewer calories from the buffet table. Apparently the reason it works is that when the small intestine absorbs fat it releases hormones that make you feel full, if you then wait 20 minutes before your second course – just keep talking, or read a book – then you will definitely eat less of a second course and so lose weight. Of course anyone on a limited budget discovered this all on their own without the benefit of a research grant. When I was at university, I made pots of homemade soup, which was cheap, so I wouldn’t need so much of the more expensive protein main meal that usually followed. I wasn’t trying to lose weight, but the end result was that I felt full by eating less. Ahead of my time, as usual.

Oh and the second tip? It’s often suggested you drink a glass of water before you eat, again to fool the stomach into thinking you are full before you start eating, but a more pleasant way to do it is include lots of water-rich foods in your diet and that means plenty of fruit and vegetables. Researchers from Penn State University found that those who did so on average ate 25% more food by weight but still lost more pounds than the control group. Again, it’s because you can eat lots of fruit and vegetables so you get the feeling of richness from the quantity, and the fibre fills you up but gives you far fewer calories.
