We can't prevent ageing, but we can age well. Our five tips for healthy ageing - including diet, exercise and outlook - will increase your vitality at any age.
For as long as humans have known about ageing, we have been searching for a fountain of youth. Although we cannot prevent ageing, there are certainly things we can do to help us embrace our age and to enjoy a good level of health well into our golden years. Here are five basic lifestyle tips that anyone can adopt to help maintain vitality in later life.
1. Quell inflammation
Inflammation is at the root of many chronic health problems, including those associated with ageing. Atherosclerosis (hardening of the arteries) and joint pain are two key examples.
The right foods
Dietary choices can go a long way towards stopping inflammation before it starts.
Avoid sugars, processed foods and high intakes of saturated fats.
Increase foods that help quell inflammation, such as fresh vegetables (especially green leafy vegetables) and omega-3 fatty acids from fish and seeds.
Helpful herbs and spices
Various herbs and spices also have potent anti-inflammatory effects.
Turmeric’s key component, curcumin, has anti-inflammatory abilities, which makes it of interest in helping to relieve many painful conditions. Much interest also exists for the possible role of curcumin in cancer prevention due to promising results seen in animal studies.
In humans, turmeric, in combination with soy isoflavones, has been shown to help reduce elevated PSA (prostate-specific antigen) levels. This could make this combination helpful in the prevention of prostate disease, possibly including prostate cancer, one of the most common cancers in men as they age.
Fish oil supplements allow people to take in the higher doses of fish oil required to help control inflammation, without a very high intake of fish (which may increase intake of unwanted contaminants such as heavy metals). Fish oils have the added benefit of supporting healthy triglyceride (blood fat) levels, which can contribute to heart health.
2. Load up on antioxidant-rich foods
Diets high in antioxidant-rich foods have been linked to a reduced risk of many diseases. Antioxidants are vital in protecting the body from free-radical damage and keeping cells and tissues healthy.
Oxidative damage has been shown to play a role in many age-related health problems, including macular degeneration (the leading cause of blindness in the developed world), cataracts, cardiovascular disease and neurological diseases such as Parkinson’s.
The right foods
Conveniently, most of the same foods listed earlier for their anti-inflammatory effects are also rich in antioxidants, so reaching for more fruits, vegies, fish, nuts and seeds will allow you to support healthy ageing in multiple ways.
Helpful supplements
Some supplements may also offer benefits when it comes to the prevention and management of health complaints seen more frequently as we age.
Resveratrol is a polyphenol, first identified in grape skins, and is thought to be a key player in the reputed health benefits of red wine. Unfortunately, almost all of the research on resveratrol was conducted in vitro (in a test tube) or in animals until very recently.
But study results published in the last two years are now showing that resveratrol could offer benefits in the prevention and management of common health problems in humans, such as diabetes and cardiovascular disease.
Pycnogenol is an extract of French pine bark that has a long list of studies citing its benefits.
3. Keep on rollin’ (the importance of exercise)
As the old saying goes, a rolling stone gathers no moss, and active bodies are generally healthier bodies at any age. The importance of regular exercise to healthy ageing cannot be overemphasised.
The research
Study after study has shown the positive effects of physical activity on age-related concerns.
It’s never too late
Best of all, it’s never too late to get rolling! Even in elderly adults, regular exercise can produce beneficial effects. One study found that six months of resistance training produced significant gains in muscle strength and lean body mass in elderly participants.
Add fish oil
Want to get even more out of your exercise? Try adding fish oil. It turns out fish oil may also enhance the benefits of exercise in those over 60. In a study of women with an average age of 64, adding 2 g a day of fish oil to a strength training program resulted in greater gains in muscle strength compared to women on the same program who did not receive fish oil.
4. Drink more tea
I remember, growing up, that a cup of tea was my mother’s cure for just about anything that ailed us. Turns out Mum was not far off, with more and more research showing the health benefits of tea. There is now little doubt that tea should be part of everyone’s healthy ageing program.
Heart health
Findings in recent studies make tea a real contender in the search for dietary factors to improve cardiovascular disease risk.
Blood pressure and cholesterol—Regular tea drinking has been associated with lower blood pressure readings in women over the age of 70 and with significant reduction of total and LDL cholesterol in both men and women who have elevated cholesterol levels.
Inflammation markers—In a study of men 55 years and younger, six weeks of black tea consumption was shown to reduce both markers of platelet aggregation (a clotting risk factor) and C-reactive protein (CRP), an inflammation marker considered a risk factor for cardiovascular disease. Other studies have confirmed the effects of tea on CRP levels with one showing that 3 cups (750 ml) of black tea a day for 12 weeks could reduce CRP levels by more than 50 per cent in men and by 41 per cent in women.
Cancer fighter
Tea, and specifically green tea, is also a potential cancer fighter.
In a group of men at high risk of prostate cancer, one year of supplementation with high doses of green tea catechins resulted in a dramatic reduction in the formation of prostate tumours compared to placebo. At the end of one year, only one tumour occurred in the green tea group, compared to nine in the placebo group—a remarkable difference and with no reported side effects.
Brain boost
Regular intake of either green or black tea has also been associated with better cognitive function in older adults, with improvements in memory and other important markers of mental sharpness.
Smooth skin
As an added bonus, tea may also keep you looking younger! In a 12-week study, women who received a supplement providing 1400 mg of catechins from green tea were found to have better overall skin quality, including improved blood flow and oxygenation of the skin, reduced roughness and better elasticity.
5. Keep a positive outlook
Evidence is accumulating for a link between negative outlooks and bad health. The link seems particularly strong for cardiovascular health, with researchers showing that regularly experiencing hopelessness, pessimism, worry, anxiety, anger or hostility can increase disease risk.
Heart concerns
People who regularly experience the world through these types of emotions have been found to be at increased risk of concerns such as coronary artery disease, slower recovery from bypass surgery and complications from such surgery, or increased risk of heart attack.
How, exactly, negative outlooks affect cardiovascular health (and potentially health in general) is not fully understood, but it is likely a result of a variety of factors such as increased stress hormones, tendency towards more unhealthy lifestyle choices and withdrawal from or rejection of important social support networks.
Menopausal symptoms
The impacts of negative outlooks are not restricted to cardiovascular health. In a revealing study on the impact of attitude on menopausal symptoms, a 2010 study found that women with a negative attitude towards menopause were likely to report a higher number of symptoms when they themselves began their menopausal transition.
In another study, postmenopausal women with high levels of hostility had a 23 per cent higher risk of cancer-related deaths as compared to optimistic women. So how you look at things can have a major impact on how they affect you!
Although there will likely never be a fountain of youth, getting older does not have to mean a dramatic reduction in health or vitality. Taking steps such as keeping active, controlling inflammation, boosting antioxidant intake and staying positive can go a long way towards helping to keep you healthy at any age.
