Sour foods are generally acidic. This quality can be measured, but it’s tricky. Sour does have other chemical properties and some foods can be acidic because they are pungent. Many people do not like to eat their vegeta- bles, their phytonutrient content can make them bitter. These seem to have been produced by the plant though its evolution fo r self-protection. These phytonutrients are things like phenols, flavonoids, isoflavones, terpenes, glucosino- lates, and other compounds that can help fight off cancer and produce positive health effects, but may not appeal to our sense of taste. Healthy plants produce more of these; this is what gives them the ability to fend off pests. Because of this bitterness, many large food suppliers or growers have sought to breed a lower level of these nutrients into their crops to improve desirability and hence sales. Though calcium is vital for the health of plants and humans, its content in veggies has also been thought to increase bitterness. A reduction in the supply of calcium to a plant will reduce its calcium content and lower bitterness, but is it appropriate to reduce calcium? Whether we realize it or not, the aspect of bitter within a vegetable adds to the overall richness and enjoyability of food and can balance out a dish that would otherwise be too sweet or salty. grow cycle 111
