Basil, easily recognized by its fragrant, green, oval-shaped leaves, makes an appearance in many foods including pasta, salads, sandwiches, cocktails and more. This delicious herb is best known as the star ingredient in pesto, a thick paste made from basil, pine nuts, oil, and parmesan cheese. First cultivated in India thousands of years ago, basil has since been incorporated into a variety of ethnic cuisines from Italian to Thai.
As well as adding a fresh taste to food, this bright green herb also has beneficial health effects. Basil is a good source of vitamin K: 2 tablespoons of fresh basil contains about 20% of the daily recommended intake of this nutrient.(1) Fresh basil is also a good source of beta-carotene, a powerful antioxidant that is converted to vitamin A in the body. Antioxidants are vital for keeping cells healthy and reducing the number of damaging free radical molecules in the body. Basil is also widely used in Ayurvedic medicine to treat a variety of ailments, including arthritis and other inflammatory diseases. (2)
Basil oil, extracted from the leaves of the plant, is a natural antimicrobial and can kill or inhibit the growth of bacteria. Scientists have shown that basil oil reduces the growth of a number of food-borne bacteria species including cholera (V. cholera) and E. coli O:157:H7 (3-5). Given recent outbreaks of food-borne illnesses, cooking with natural ingredients such as basil oil which inhibit bacterial growth is a great way to make food safer as well as tastier. Although basil shows promise as a natural antibacterial agent, it's important to note that most scientific studies looking at this question have been done in laboratory settings using high doses of basil extract. The effect on bacterial growth observed by home cooks using smaller amounts of basil or basil oil is not clear.
In addition to its health-promoting qualities, basil is easy to grow in a sunny windowsill or garden. A handful of basil leaves can add a delicious flavor to a wide variety of dishes – a few ideas are listed below!
Cooking with basil:
- Use fresh basil as a pizza topping along with tomato sauce and fresh mozzarella
- Add fresh or dried basil to tomato-based pasta sauces
- Add chopped fresh basil to fruit salads or green salads for a refreshing flavor twist
- Mix with ripe tomatoes, garlic, oil, and balsamic vinegar for a quick bruschetta appetizer
- Choose fresh basil over dried basil when possible, as fresh basil contains the basil oils.
- Look for vibrant, green basil leaves. Store fresh basil in the refrigerator; fresh basil can also be frozen.
