Raumgarten Makes the Difference - Nutrient Comparison: Supermarket Vegetables vs. Homegrown

Today, we're focusing on "nutrients."

Food we buy in supermarkets has already lost many important nutrients.

A main reason is the "dilution effect," which occurs when plants are bred for higher yields. This distributes nutrients over more plant material, and the ๐—ฐ๐—ผ๐—ป๐˜๐—ฒ๐—ป๐˜ ๐—ฝ๐—ฒ๐—ฟ ๐˜‚๐—ป๐—ถ๐˜ ๐—ฑ๐—ฒ๐—ฐ๐—ฟ๐—ฒ๐—ฎ๐˜€๐—ฒ๐˜€. Genetic adaptations, intended to make plants more resilient, also often lead to nutrient deficiency.

Modern cultivation methods further exacerbate the problem.

Long transport and storage times also damage sensitive vitamins like A, C, D, and E. In extreme cases, these vitamins can ๐—ฏ๐—ฒ ๐—ฎ๐—น๐—บ๐—ผ๐˜€๐˜ ๐—ฐ๐—ผ๐—บ๐—ฝ๐—น๐—ฒ๐˜๐—ฒ๐—น๐˜† ๐—น๐—ผ๐˜€๐˜. An example of this is the dramatic decrease in vitamin C content in tomatoes, which has ๐—ฑ๐—ฟ๐—ผ๐—ฝ๐—ฝ๐—ฒ๐—ฑ ๐—ฏ๐˜† ๐˜‚๐—ฝ ๐˜๐—ผ ๐Ÿณ๐Ÿฎ%. As shown in the following view, the content of all listed vitamins and nutrients in tomatoes has decreased.

Indoor gardens offer a solution here, as in our systems plants are grown under ๐—ถ๐—ฑ๐—ฒ๐—ฎ๐—น ๐—ฐ๐—ผ๐—ป๐—ฑ๐—ถ๐˜๐—ถ๐—ผ๐—ป๐˜€, with precisely controlled light, temperature, and humidity. This enormously increases nutrient density.

Since plants are ๐—ด๐—ฟ๐—ผ๐˜„๐—ป ๐˜„๐—ต๐—ฒ๐—ฟ๐—ฒ ๐˜„๐—ฒ ๐—ฐ๐—ผ๐—ป๐˜€๐˜‚๐—บ๐—ฒ ๐˜๐—ต๐—ฒ๐—บ, there are no long transport routes, which also minimizes nutrient loss. Additionally, indoor gardens protect plants from environmental influences that could damage vitamins, ensuring fresher and more nutrient-rich food.
