The notion that people can get all their essential nutrients from food is outdated. While it’s possible to obtain many nutrients from your diet, there are a plethora of influences in the modern world that make it difficult for the average American adult to maintain their health strictly through food. Emerging research demonstrates that many people are deficient in critical nutrients, like omega-3 fatty acids, vitamin D, and magnesium, among others. There are many reasons why nutritional deficiencies exist. The lack of nutrients in processed and junk foods plays a role, as does nutrient-depleted soil, environmental toxins, and chronic stress. Most people need customized nutritional therapies and supplements to fight off disease, combat inflammation, increase energy, and maintain health over the course of their lifetimes.
