Ask a Dietician — Foods that Prevent Illness
Question: Are there some foods that can prevent illnesses?
Foods that offer additional health benefits other than basic nutrition are known as functional foods. These foods contain a naturally present biologically active component that is believed to decrease the risk of developing a chronic disease. Some of these foods have gained popularity in the media because they are widely promoted to prevent conditions such as cancer, osteoporosis and obesity.
Oats – Oat Products contain a soluble fibre called b-glucan. This fibre has been shown to reduce total and low-density (LDL) cholesterol. This effect can reduce one’s risk for coronary heart disease. Tasty Tip – try a steamy bowl of oatmeal for breakfast.
Tomatoes – Tomatoes contain a powerful antioxidant called lycopene that is perceived to reduce the risk of developing certain types of cancers because it is an effective quencher of free radicals. Tasty Tip – add sliced tomatoes to your sandwiches; bring some color to your salad with cherry tomatoes or make some homemade tomato soup.
Tea – Tea, especially green tea, contains a high concentration of polyphenols and flaveniods. These compounds are respectively suspected to have anticancer properties and reduce risks for developing cardiovascular disease. Tasty tip – Caffeine-free green tea with a little bit of honey can be a refreshing way to end a nice meal with family or friends.
Citrus Fruits – In addition to the essential nutrients of vitamin C, folate and fibre, citrus fruits such as oranges, grapefruit, lemons and limes contain a class of phytochemincal called limonoids. Limonoids are currently being studied to explore their role in fighting and preventing cancer. Tasty tip – On a warm day, juice your own citrus fruits to make a fresh squeezed class of citrus or try some grapefruit and oranges in a refreshing fruit salad.
