Backyard Gardens Boost Health
Starting a backyard vegetable garden is being touted as one of the healthiest choices for both people and the planet. The practice promotes local, organic, and seasonal eating while reducing environmental impact. A master gardener also offered tips on growing tricky celery in challenging climates like Missouri.
A meta-analysis of 22 studies found that gardening leads to significant health benefits, including reductions in depression, anxiety, and body mass index, along with increases in life satisfaction and a sense of community. These positive effects on well-being were found to be even more pronounced than the physical health benefits. The nutritional value of vegetables begins to decline the moment they are harvested. Produce from a backyard garden is often more nutrient-dense as it can be picked at peak ripeness, unlike store-bought options which are often harvested early to withstand shipping and may be treated with waxes or chemicals to extend shelf life. For example, spinach can lose over half of its folate within a week of being harvested. Home gardening allows for the cultivation of a wider array of vegetable varieties, including heirlooms, which can offer a greater range of colors, textures, and flavors than typically found in supermarkets. Research comparing USDA data from 1950 and 1999 found significant drops in several key nutrients in commercially cultivated varieties, which are often bred for high yields and durability rather than nutritional content. The concept of producing food at home has a rich history, notably with the "victory gardens" or "war gardens" during World War I and World War II. These gardens were promoted by governments to counter food shortages and reduce pressure on the commercial food supply. By 1944, an estimated 20 million victory gardens in the U.S. produced about 8 million tons of food, equating to more than 40% of the fresh fruits and vegetables consumed in the country at the time. Community gardens serve as hubs for social connection, with one study indicating that neighborhoods with these gardens see a 20% increase in neighborly interactions. These shared spaces have also been linked to reduced crime rates as they foster a sense of community ownership and pride. While beneficial, urban gardening can have a larger carbon footprint than conventional farming, primarily due to the materials used for infrastructure like raised beds. However, certain crops like tomatoes grown in open-air urban plots can have a lower carbon intensity than those grown in conventional greenhouses. Extending the life of garden infrastructure and using recycled materials can help mitigate the environmental impact.
