Eat a Rainbow – Red Foods

Red foods are real health heroes when it comes to a balanced diet. Packed with lycopene they can protect our skin as well as reduce risks of cancer. Dietitian Juliette Kellow, BSc RD takes a look at why we should get red foods onto our plates.

Why Should I Eat Them?

Red foods such as tomatoes, watermelon, guava and pink grapefruit are a good source of a carotenoid called lycopene, which gives these foods their red colour. This antioxidant has been shown to help protect against cancers of the lung, colon, oesophagus, breast and skin. However, it’s thought to be a true health hero when it comes to preventing prostate cancer. Five studies suggest the risk of prostate cancer drops by 30-40 percent when high intakes of tomatoes or lycopene are consumed.

An Italian study reveals that consuming seven or more servings of tomatoes or tomato products every week, compared with less than two servings, may reduce the risk of gastric cancer by 50 percent. Research also shows that lycopene may help to lower blood cholesterol and so may reduce the risk of heart disease. And foods rich in lycopene may also help to make the skin more resistant to sunlight.

In a small British study, adults who consumed a large amount of tomato puree (5tbsp) with olive oil every day for 12 weeks and then were exposed to UV sunlight at the beginning and end of the trial had 33 percent more protection against sunburn than those who just consumed olive oil! Far more research is needed to understand the potential skin protective effects of lycopene and it’s unlikely that eating more lycopene-rich foods such as tomatoes will ever replace sun safety messages such as advice to wear sun-screen. That said, adding more to your diet is unlikely to do any harm.

Better still, our bodies are able to absorb more lycopene when it’s in the form of food that’s been cooked or processed. This makes tomatoes an important provider of lycopene – ketchup, puree, canned tomatoes and ready-made sauces all contain more lycopene than fresh tomatoes, and the body is better able to use it. Adding fat also seems to boost the absorption even more, so don’t be afraid to serve tomatoes with a little mozzarella or drizzling a salad with a teaspoon of olive oil.

It’s not just lycopene that gives red foods their health hero status. Many, including cherries, cranberries, red plums, red onions, radishes, raspberries and strawberries are also good sources of anthocyanins, which are also found in large amounts in blue and purple foods (see Purple and Blue).
