Our motivation to grow nutrient-dense foods has been gaining steam over the past few years. But how do we achieve nutrient-dense food? Well, it really begins with your soil quality, and anyone who has farmed or grown vegetables using natural methods will recognize that this process doesn’t happen overnight. But luckily, there is a good place to start. Brix is a measurement of the sugars, amino acids, oils, proteins, flavonoids, minerals and other nutrients in food.Therefore, the Brix level of a crop is directly correlated with nutrient density. In order to test Brix, you take some of your sample and squeeze out some of the juice (plant sap) using a vice grip or garlic press. You then squeeze the juice onto a refractometer and look through it to see the results (this would ideally be done on a clear day).In the same way that a pencil placed in a glass of water appears bent because of the light passing through it, the plant juice will also bend and the amount of bending reflects the richness of the juice. The richer the juice, the more dissolved sugar, the higher the Brix. Higher Brix equals higher complex sugar level yielding a sweet fruit. Higher Brix also equals higher minerals, and higher minerals equal fewer diseases and pests. Measuring Brix levels are important to know if you want to be able to detect problems before they become an issue. They are also helpful in determining what kind of minerals may be deficient in your soil, as well as giving you an idea any amendments that may radically affect the success of your crop. Keeping in mind that great soil doesn't happen overnight, Brix test can also help measure soil progress over time and give you an idea of how far you've come at achieving truly nutrient-dense food.
