Food Sovereignty and Indigenous Health | Mariah Gladstone | TEDx

Colonialism systematically destroyed indigenous food systems across North America through policies like the Doctrine of Discovery and Manifest Destiny. Between 1800-1900, over 80% of U.S. territory under indigenous control was reduced to less than 2%. Key policies including the Indian Removal Act of 1830, Homestead Act of 1862, and Dawes Act of 1887 systematically dismantled indigenous sovereignty. The U.S. government deliberately destroyed bison populations (from nearly one billion to fewer than 500), eliminating a primary food source for plains tribes. Boarding school systems then stripped generations of indigenous peoples of ancestral knowledge about hunting, gathering, plant identification, and sustainable living through forced assimilation. This historical trauma explains why indigenous food knowledge was lost and why indigenous restaurants remain absent from major American cities despite indigenous peoples having lived on these lands for millennia.

Before European colonization, Native nations across North America maintained distinct, culturally defined relationships with traditional foods. Diets were local and seasonal, rotating among hundreds of plant and animal species. The Elgangquin associated June with strawberry season, while the Shauni called September the paw pa moon for large fruits. The Neoni and Cherokee relied on the 'three sisters'—corn, beans, and squash—that protected each other and grew better together. However, colonization devastated these systems over 300 years, with Native nations losing 99% of their traditional lands. Federal boarding schools separated children from families, languages, and foods, while settlers exploited resources unsustainably. The Great Sue viewed buffalo as essential to survival, but by 1887, fewer than 100 remained due to targeted extermination by soldiers who understood that eliminating buffalo would force starvation and treaty surrender.

This extended dialogue explains the historical reality of Native American displacement during westward expansion. The speaker describes how indigenous tribes were 'stolen clean away from them' and 'killed or herded up to the reservations in the middle of nowhere.' The conversation reveals the systemic injustice of forced relocation, where Native peoples lost their ancestral lands and were moved to remote areas. This reflects the broader historical pattern of land dispossession that accompanied American expansion.

Colonial policies systematically destroyed Native American food sovereignty through multiple mechanisms. The Indian Removal Act forced mass displacement, destroying ancestral food knowledge tied to specific landscapes. Reservations confined Native peoples to land unsuitable for traditional hunting and gathering. Government rations replaced nutritious traditional diets with nutritionally inadequate alternatives. This systematic destruction of food systems contributed to cultural trauma and health crises that persist today, demonstrating how food policy serves as a tool of colonial control.

Indigenous food systems were systematically destroyed through colonial policies spanning centuries. Colonialism—defined as acquiring political control, occupying with settlers, and exploiting economically—occurred globally but was particularly devastating in North America. Manifest Destiny, emerging from the Doctrine of Discovery, justified European land claims. Between 1800-1900, Indigenous land ownership dropped from over 80% to less than 2%. Key policies including the Indian Removal Act (1830), Homestead Act (1862), and Dawes Act (1887) systematically dispossessed Indigenous peoples. The systematic destruction of bison herds eliminated primary food sources, reducing populations from millions to fewer than 500. Simultaneously, military-style boarding schools stripped children of language, religion, and traditional knowledge through physical, sexual, and mental abuse. The Commodity Food Program replaced traditional diets with processed foods, contributing to health crises including diabetes and obesity. Over 100 tribes were dismantled, Indigenous peoples couldn't vote until 1965 or practice religions freely until 1978, preventing cultural continuity and food sovereignty.

Neurotransmitters—chemical messengers controlling mood, energy, and relaxation (serotonin for happiness, GABA for calmness, dopamine for energy)—require adequate B-vitamin levels to be synthesized properly. These vitamins are found in whole grains, seeds, animal products, and are produced by healthy gut flora. Whole grains are living organisms containing vitamins, enzymes, minerals, and antioxidants in the germ, while the bran contains B-vitamins and fiber that feeds beneficial gut bacteria. Refined grains remove these nutrients entirely. Beriberi disease epidemic in Asia occurred when rice was refined, causing heart failure and edema due to thiamine (B1) deficiency. Modern diets rich in refined carbohydrates lead to micronutrient deficiencies despite high caloric intake. The paradox of obesity and micronutrient deficiency occurs because the body signals hunger continuously when micronutrients are lacking, even when consuming excess calories.

Over 90% of patients cannot tolerate refined sugar and refined flour. This is not because sugar or flour are inherently bad, but because modern versions are ultra-refined. Traditional diets included occasional consumption of natural sugar and whole grain bread without problems. The problem lies in the processing that removes beneficial nutrients and creates easily digestible, inflammatory foods.

When flour was first refined, people experienced massive nutritional deficiencies because the B vitamins in whole grain were removed. This led to conditions like thiamine deficiency and pellagra. The term 'enriched flour' was introduced because people were getting sick from the lack of nutrients. This historical context shows how the refining process itself created nutritional problems, and the question remains whether the bigger issue is the gluten or the glycemic index.

The primary nutritional cause of diabetes is constant consumption of simple carbohydrates including sugar and refined flour products. Refined sugar is identified as the number one cause of diabetes, obesity, dental caries, and osteoporosis. Refined sugar is unnatural and lacks the nutrients found in natural sugar (piloncillo), causing the body to draw calcium from bones and teeth to compensate. A single can of Coca-Cola contains 10-27 teaspoons of sugar. Mexican bakeries' products contain three lethal ingredients: refined flour, refined sugar, and vegetable shortening. The natural diet should include fruits, vegetables, whole grains, legumes, seeds, nuts, fish, and poultry, while avoiding red meat and pork.

Whole foods are becoming less common as processed foods increase. Processed foods contain high levels of fat, salt, and sugar, are easy to store, taste good, and are inexpensive, but lead to health problems over time. The recommended ratio is 80% whole foods and 20% processed foods. Whole foods like cottage cheese, plain meat, and homemade salads are easily identifiable by their simple ingredient lists. Macronutrients affect body composition, while micronutrients affect health. Modern foods have lost 5-10% of their micronutrient content compared to 50 years ago, which is considered a mathematical error rather than a significant change. Supplements are temporary solutions and often work as placebo effects. All micronutrients should be consumed from food because the body absorbs minerals much better from food than from supplements.

Bison are the keystone species that maintain healthy North American grassland ecosystems, as they evolved in concert with these landscapes and their grazing patterns, waste decomposition, and movement create the conditions necessary for plant and animal biodiversity; the restoration of bison populations is essential for ecological balance, food sovereignty, and the health of both the land and human communities.

Bison are keystone species essential for maintaining healthy North American grassland ecosystems, as they perform critical ecological functions including carbon sequestration through their digestive processes and enabling the decay of organic matter in their stomachs, which cannot occur naturally in areas with irregular rainfall; their historical near-extinction and subsequent restoration efforts demonstrate how reintroducing keystone species can restore biodiversity and ecosystem health while supporting food sovereignty and cultural preservation for Native American communities.

The American bison is a keystone species whose grazing patterns can restore native prairie grasslands when managed correctly, and ranchers are working to preserve pure Yellowstone bison genetics to help rebuild these ecosystems.

Bison function as keystone species that maintain prairie ecosystem health through multiple mechanisms. Their wallowing behavior creates soil depressions that become critical microhabitats, exploding with life during spring when water saturates the ground. Bison dung fertilizes soil and supports hundreds of insect species, while their fur provides nesting material for birds and small mammals. The Nature Conservancy's Bison Project at the Tallgrass Prairie Preserve demonstrates how reintroduced bison populations can restore native plant communities, increasing biodiversity to include 750 plant species, 250 birds, and 80 mammals. This ecological impact validates bison as essential components of healthy prairie ecosystems.

Bison are keystone species whose populations have rebounded from near extinction in the 1800s to tens of thousands today, and transferring bison from federal to tribal land under the Inflation Reduction Act is expected to improve conservation outcomes because tribal governments have stronger economic and cultural stakes in protecting these animals, which in turn positively impacts the entire ecosystem through their grazing and movement patterns.
