In January you can barely go anywhere without being confronted by yet another new year’s diet. But what you eat can have an effect on how quickly you age, so it’s worth paying attention to what you’re putting in your body.

Writing for NDTV, nutritionist Shilpa Arora gave five top tips for your diet if you want to slow the ageing process.

Number one on the list is to eat more antioxidant rich food. The best way to ensure you do this is to include fresh fruit and vegetables in your diet, and to use colours as an indication of high antioxidant content – so think green spinach, red tomatoes, purple beetroots.

Buying seasonal vegetables and fruit is also beneficial for your health, as these products will be rich in phytonutrients.

As well as fruit and vegetables, protein is an important part of your diet, and Ms Arora advises buying organic meats and using beans and pulses in dishes to ensure you’re getting enough protein.

Meanwhile, two scientists have written about how diet can affect ageing in the Daily Mail. They highlight the importance of telomeres, which sit at the end of your DNA strands and protect it. The longer your telomeres, the more resilient your body will be to illness and ageing.

So, among the telomere-lengthening foods they recommend are nuts, legumes and seeds, wholegrain produce, all fruit and vegetables, and foods high in omega-3 oils.

If you undertake thread lift courses to help people get a youthful glow in their faces, you might want to advise them of the role their diet plays in ageing, and encourage them to read up on foods that can help slow the ageing process.
