While none of us will live forever, you can add some extra years on to your life by paying attention to what you eat. To increase your lifespan as well as improving the quality of your life, check out these eight foods that help you live longer.

1. Brightly coloured fruit and vegetables

Research suggests that those who eat more fruit and vegetables tend to live longer than those who don’t, due to the nutrients they contain. While all fruit and veg is good for you, brightly coloured produce is particularly beneficial as the natural pigments which give them their color can also help prevent cancer. The Okinawans – who are reputed to have the world’s longest life expectancy and who have low rates of heart disease and cancer – have a diet that is rich in fruit and veg, especially dark green and yellow varieties. In particular, the Okinawan diet features large quantities of sweet potatoes, having replaced the traditional Japanese staple of rice with this vibrant veg.

2. Dark chocolate

Good news for chocoholics – chocolate can help you live longer!  Cocoa beans are packed with antioxidants which studies have found can help cut your risk of heart disease – the biggest killer in the Western world.

This may be why Jeanne Louise Calment, who lived a grand total of 122 years and 164 days (the oldest verified age of any human being ever) put her good health down to her regular chocolate consumption. However, before you go stocking up on chocolate bars, it is worth bearing in mind that one square a day is enough to boost your health. Also, make sure you go for the over 70 per cent cocoa bars which contain more flavonoids and less sugar.

3. Oily fish

People in Japan have the longest life expectancy in the world, which may be down to their traditional diet which is high in fish. Not only does opting for fish over meat reduce your risk of many of the health problems associated with red meat, such as heart disease, but oily fish such as salmon, mackerel, sardines and trout are renowned for their health benefits. Oily fish are a good source of vitamins A and D which are good for the immune system. They are rich in omega-3 fatty acids which have been linked to a lowered risk of heart disease, brain damage and stroke. Scientists have also discovered that the DHA (docosahexaenoic acid) in fish is the key to combating Alzheimer’s: DHA slows down the progression of Alzheimer’s disease, making this the key ingredient for a healthy brain and, ultimately, a healthier lifestyle too.

4. Green tea

Another staple of the Japanese diet, green tea boasts an impressive array of health benefits, helping to improve cardiovascular health, regulate blood pressure, boost the immune system, and lower cholesterol. Studies have even suggested that drinking green tea – which is rich in health-boosting flavonoids – can help to lower your risk of cancer. Research findings published in the Journal of the American Medical Association appear to back up these health claims, as the Japanese study of more than 40,000 participants found that those who drank five or more cups of green tea a day had a death rate that was 16 per cent lower than those who drank one cup, over the course of 11 years.

5. Olive oil

Many of us stay away from fats and oils in a bid to stay trim and healthy; however, ‘good’ monounsaturated fats, which are found in olive oil, are actually essential for good health. Studies have found that regularly consuming olive oil can help cut your risk of stroke and heart disease, due to its high content of micronutrients called phenols which have anti-inflammatory and antioxidant properties. The oil is also a staple of the healthy Mediterranean diet, which studies suggests can help you live longer. Research has found that those who follow this eating plan have a 20 per cent higher chance of living longer, gaining an estimated average of two to three years.

6. Garlic

More and more evidence seems to be emerging that, of the many compounds found in garlic, 10 of them help to combat cancer. Garlic also contains immune-enhancing compounds that help to break down the substances that cause cancer. For example, diallyl sulphide, a component of garlic, is known for its ability to break down carcinogens in the body, which may have led to cancer if they weren’t destroyed. According to research, people who consume garlic regularly face half the risk of stomach cancer than those who eat little or none.

7. Cranberries

It would take a long time to list the many health benefits of cranberries but, in short, this tiny fruit is a life-saver (literally) when it comes to our health. Indeed, the little cranberry is full of antioxidant, anti-inflammatory, antibacterial and immune-boosting properties, as well as being jam-packed full of phytonutrients. The more phytonutrients we have in our body, the greater the protection. Moreover, the phytochemicals found in red fruits and berries help to combat cancer-causing molecules. In a study conducted by Cornell University, researchers tested cranberry extracts on human breast cancer cells and discovered that, over four hours, many of the same breast cancer cells had begun to die. So not only do they taste amazing, but these little red gems make a powerful addition to any diet.

8. The coffee bean

A study by the University of Scranton found that the flavonoids contained in coffee can prevent heart disease. The professor who led the experiment, Dr. Joe Vinson, says that “antioxidants are your army to protect you from the toxic free radicals, which come from breathing oxygen and eating sugar, that start chronic diseases”. The antioxidants in coffee ward off life-threatening diseases such as cancer, heart disease, diabetes, and stroke. It’s worth bearing in mind though, that caffeine raises your blood pressure, so if you’re drinking a large amount it’s best to opt for decaf, which offers the same amount of antioxidant properties as regular coffee. So let’s raise our warm mugs of coffee to health, happiness, and battling horrible diseases the tasty way. Here’s to a prosperous life!
