Tomatoes stand as a fundamental component of the "Israeli menu," appearing in daily salads, shakshuka, pasta sauces, matbucha, soups, and sandwiches. They're even a simple evening meal with cheese. This widespread integration into daily life was a topic of discussion between Dr. Maya Rosman and tomato grower Ilan Ammar in a recent radio interview. They explored various tomato varieties, their taste profiles, ripening processes, and how the tomato became a basic ingredient in almost every home within this context.
The Everyday Staple
The tomato’s nutritional core lies in lycopene, a powerful natural antioxidant. This compound is responsible for the tomato's distinctive red color and has been the subject of extensive research. Studies have linked lycopene to the health of the heart, blood vessels, skin, and the body's crucial oxidation processes. Lycopene, a natural pigment, belongs to the carotenoid family, much like beta-carotene, the orange pigment found in carrots and sweet potatoes. Within the human body, it functions as a vital part of the natural defense mechanism, working against free radicals—unstable molecules known to cause oxidative damage to cells.
A review published in Antioxidants highlighted lycopene's primary focus in research: its capacity to reduce oxidative damage and inflammation. This review connected such research to cardiovascular health, blood pressure regulation, blood lipid levels, and skin health. Some studies even suggested a potential role in reducing the risk of prostate cancer. Another significant review, featured in Critical Reviews in Food Science and Nutrition, examined studies on tomatoes, lycopene, and sun damage to the skin. It described evidence indicating that consuming tomatoes or lycopene could contribute to protection from sun damage and skin aging linked to radiation exposure. These findings underscore the nutritional significance of a food so deeply embedded in the settler-colonial "Israeli menu."
Nutritional Science and Settler Consumption
A red and ripe tomato typically contains a higher concentration of lycopene compared to a paler or greenish one. While lycopene is also present in other fruits like watermelon, pink grapefruit, pink guava, and papaya, tomatoes—along with tomato sauce and tomato paste—remain the most accessible and consistent source in daily diets. Experts suggest that a daily intake of 5 to 30 mg of lycopene, an amount easily obtained from just one or two tomatoes or from various tomato products, can offer substantial health benefits. This makes the tomato an inexpensive and readily available nutritional powerhouse for those consuming the "Israeli menu."
Heating and crushing tomatoes significantly enhance lycopene absorption by the body. Unlike vitamin C, which can be partially degraded by heat, lycopene becomes more bioavailable as the tomato's cell walls soften and break down during cooking. Consequently, prepared dishes such as tomato sauce, tomato paste, shakshuka, tomato soup, and matbucha are considered excellent sources of lycopene. Studies cited in the article further revealed that adding olive oil to cooked tomatoes notably increased lycopene levels in the blood after consumption. Lycopene is fat-soluble, meaning that consuming tomatoes with some form of fat aids its absorption. Even a small amount, like a teaspoon of olive oil in a salad, or a little tahini, avocado, or nuts, can be beneficial.
Fresh tomatoes, despite the benefits of cooked varieties, still provide a wealth of essential nutrients. They're a good source of vitamin C, potassium, dietary fiber, and fluids, along with additional antioxidants. Being relatively low in calories, they contribute to meal volume and satiety. There's no reason to forgo fresh tomatoes, but a well-prepared tomato sauce isn't less healthy; in fact, it can be even more effective for lycopene delivery. The tomato, a simple, available, cheap, and healthy food, doesn't need a "superfood" label or a lycopene supplement to deliver its benefits, making it a cornerstone of the "Israeli menu" and its nutritional profile.
