Ultraprocessed foods, seed oils, herbicides and pesticides, and fluoride: They're all targets of the "Make America Healthy Again" movement, whose chief proponent is US Health and Human Services Secretary Robert F. Kennedy Jr. Now, MAHA Films, a production company dedicated to promoting the movement's values, has released its first documentary. "Toxic Nation: From Fluoride to Seed Oils " How We Got Here, Who Profits, and What You Can Do." [The film] highlights those four food- and environmental-related issues that Kennedy's nonprofit MAHA Action ... says "silently endanger millions of Americans every day." The documentary's release follows the May 22 publication of the first MAHA Commission report, which lays the groundwork for an overhaul of federal policy to reduce the burden of chronic disease on American children. Composing up to 70% of the US food supply, ultraprocessed foods are made with industrial techniques and ingredients never or rarely used in kitchens, or classes of additives whose function is to make the final product palatable or more appealing. Ultraprocessed foods are typically low in fiber; are high in calories, added sugar, refined grains and fats, and sodium; and include additives. The [also] film raises concerns about the herbicide glyphosate, citing previously documented links to cancer. Sources also said glyphosate may cause endocrine disruption and damaged gut microbiomes, with the latter potentially increasing risk for irritable bowel diseases and celiac disease.
