Salt Water Makes Tomatoes Healthier

We’ve talked about how seaweed can improve your tomato growth, yield, and flavor here, but did you know that simple seawater can also help your tomatoes?

Researchers at the University of Pisa in Italy have found that diluted seawater can not only be used to grow tomatoes but can even produce fruit with higher concentrations of cancer-fighting antioxidants.

Riccardo Izzo and his colleagues in Pisa used cherry tomatoes to determine whether the use of diluted seawater for irrigation combined with selective picking could improve the nutritional qualities of tomatoes.

In fact, cherry tomatoes exposed to about 10% seawater and picked at the “red-ripe stage” showed significantly improved antioxidant-related nutritional values. The seawater probably actually caused salt-related stress, according to researchers, stimulating production of healthy antioxidants as well as Vitamins C and E.

Besides producing healthier and tastier tomatoes, using seawater can also be a rather “green” thing to do. According to the researchers’ report, “The controlled use of alternative water resources, such as diluted seawater, could be a valid tool to face drought in the Mediterranean region.”
