The quest for eternal youth is as old as time. From magic potions and mythical vampires to skincare, cosmetics, and plastic surgery, we often chase extraordinary solutions to ageing. However, one of the most powerful anti-ageing secrets may be found simply in what we eat.

Which nutrients are best for anti-ageing?

Eating a nutrient-rich, balanced diet benefits our health in countless ways. Certain nutrients play a key role in supporting specific functions within your body. As we age, some become especially valuable in helping us stay healthy over time.

Dr Gail Clifford is a Wall Street Journal international best-selling author based in Greater Orlando, USA. She explains that these nutrients help keep your body working well for longer.

"They protect your cells, reduce inflammation, and lower your chance developing of long-term diseases - such as heart disease, cognitive decline, and even some cancers," she says. "When your body has what it needs to repair damage, manage stress, and stay balanced, you are more likely to feel better and stay active as you age."

She emphasises that your focus should not be on reversing ageing, but rather on ageing well - maintaining energy, sharpening your mind, and keeping your body strong for as long as possible.

Some foods are naturally richer in these nutrients than others. While a balanced diet that includes a variety of nutrients is key to staying in top shape, the foods that promote a longer, healthier life tend to be good for our overall well-being too.

"Whole, plant-forward foods are where it is at," says Clifford. "Eating a variety from the following food groups gives your body a strong nutritional foundation to thrive as you age."

Certain diets and eating patterns can help promote longevity and support healthy ageing.

Clifford explains that the Mediterranean diet is the best-known - and most widely studied - of these approaches.

"It is full of fruits, vegetables, olive oil, whole grains, fish, and legumes, and it has been linked to lower rates of heart disease and cognitive decline," she says.

"The DASH diet, which was initially designed to help lower blood pressure, is also excellent for healthy ageing."

Elena Rolt is a registered nutritional therapist from health.miro, UK. She explains that intermittent fasting can also offer health benefits, including potential effects in slowing the ageing process.

"Clinically, intermittent fasting supports metabolic and brain health, lowers inflammation, and improves gut integrity," she says. "It also helps to regulate your hormones related to hunger, satiety, and reproductive function."

She adds that calorie restriction and a fasting-mimicking diet can enhance nutrient-dense foods by boosting their benefits to improve metabolism, reduce inflammation, and support cell renewal

In short, being mindful of the foods we include in our diet is a key step toward staying healthier, and living longer. It works hand in hand with other building blocks of longevity - such as regular exercise, managing stress, and getting enough sleep. While diet isn’t the only factor that supports a long, healthy life, it plays a significant role in a lifestyle that benefits both our inner and outward health.
