Ageing is inevitable, but the speed at which it happens is not and there are a number of ways we can put the brakes on. Ageing is driven by the build-up of damage in our cells, tissues and organs, which is a result of our lifestyle and our genetics. Eating a healthy, balanced diet can affect how we look and the condition of our skin, but we now know it can also reduce our chances of developing age-related diseases such as diabetes and cancer, as well as other negative aspects of getting older.
Our genes play a part in how we age; the rest is down to our lifestyle, so the choices we make regarding what we eat, the amount of exercise we do and how we manage stress all have an effect on our individual ageing process.
With regards to nutrition, it’s really important to include antioxidants in our diet. Antioxidants are substances that help protect the body against damage from free radicals. Free radicals can cause oxidative damage to cells and tissues, resulting in age-related diseases and symptoms of ageing such as developing wrinkles, declining vision, poor digestion, fatigue, a decrease in cognitive function and so on.
The following vitamins and minerals have antioxidant properties:
l Vitamins – A, C and E
l Minerals – Zinc, manganese, copper, selenium
Good sources of antioxidants include broccoli, carrots, peppers, apricots, whole grains, nuts and seeds.
However, antioxidants are only half the story. B vitamins control a process in the body called methylation, which protects DNA and allows healthy new cells to develop. You can check how well your methylation processes are working by measuring your homocysteine (an amino acid) levels, as high levels indicate a higher risk for degenerative diseases. Changes to diet and ensuring the right intake of B vitamins can help to reduce your homocysteine levels.
Regular exercise can add an average of 7 years to your lifespan. Ideally, incorporate a combination of regular gentle stretching exercise, such as Pilates or yoga, along with aerobic activity such as brisk walking, swimming or playing tennis, into your daily routine. The benefits of aerobic exercise include reducing blood cholesterol levels, pulse rate and blood pressure, which all support improved cardiovascular health. Resistance training is good for bone health, so also try to include three to four sessions every week.
It’s important to avoid or reduce stress as much as possible as prolonged periods of stress can result in the depletion of the adrenal hormone DHEA. Low levels of DHEA are associated with a higher risk of developing many diseases and speeds up the ageing process in general.
