Food Sovereignty Is Health Sovereignty: What Structures Shape Cancer Risk in Black Communities

Environmental Justice · Public Health · Social Justice

The question is not whether processed meats and excessive alcohol increase cancer risk. The research is clear: they do. Cancers linked to diet and behavior are among the most preventable. But framing this as a matter of individual food choices — myths to debunk, better decisions to make — misses the structural reality that shapes what most communities actually eat, and why.

Black Americans face disproportionately high rates of colorectal cancer, breast cancer, and stomach cancer. More than 5% of new cancer cases each year are associated with poor diet. But “poor diet” does not happen in a vacuum. It happens in communities that were systematically denied access to fresh food, whose corner stores were stocked with processed alternatives because supermarkets refused to build there, whose ancestral food traditions were disrupted first by enslavement and then by commodity programs that funneled processed food into low-income households.

This is not a personal failure. This is policy.

What the Research Confirms

Oncology dietitians and cancer researchers are consistent on the evidence: processed meats — sausages, bacon, deli meats, cured and smoked products — carry measurable cancer risk. Consuming processed meat is linked to a 6% higher risk of breast cancer, primarily in postmenopausal women. Colorectal cancer risk is also significantly elevated with regular processed meat consumption. Alcohol compounds these risks across multiple cancer types — including stomach cancer, as identified by the World Cancer Research Fund.

Many other commonly feared foods — non-organic produce, food dyes, artificial sweeteners, eggs, dairy — do not carry the same evidence-based risk. A diet high in flavonol-rich foods — dark leafy greens, berries, tea, onions — is associated with a 50% reduction in cancer mortality risk. The protective elements of diet are as real as the harmful ones. And many of those protective foods are central to ancestral African food traditions.

But knowing the research and having access to its recommendations are two different things. And the gap between them is structural.

How Policy Shaped What We Eat

The concentration of processed food in low-income, predominantly Black communities did not happen by accident or by individual preference. It was produced by decades of policy. USDA commodity support programs historically subsidized industrially processed foods — canned goods, processed cheese, ground beef — and funneled them into school lunch programs, food assistance, and community food banks serving low-income populations. Fresh produce, whole grains, and the foods that ancestral African diets centered received no equivalent support.

Simultaneously, redlining and discriminatory business lending practices meant that full-service grocery stores systematically avoided Black neighborhoods. The result was food apartheid: communities with the highest nutritional need surrounded by processed food, with fresh produce inaccessible or unaffordable. The global pattern of colonialism and health policy follows the same logic — the most vulnerable communities bear the costs of systems designed to extract, not nourish.

This is not ancient history. It is the immediate context of today’s cancer disparities.

What Ancestral African Diets Actually Looked Like

Before the disruption of enslavement and colonization, African dietary traditions across the continent were — by the standards of modern cancer prevention research — extraordinarily protective. West African cuisines centered legumes, dark leafy greens, root vegetables, whole grains like millet and sorghum, fermented foods, and healthy fats from palm oil, groundnuts, and coconut. East African dietary traditions included abundant fermented dairy, legumes, and vegetables. Southern African traditions included wild-harvested plants, organ meats from animals raised on natural diets, and fermented grain beverages that supported gut microbiome diversity.

Obesity, closely linked to cancer recurrence and risk, is also tied to the nutritional displacement communities experience when ancestral food is replaced by processed alternatives. The evidence for ancestral dietary patterns as cancer-protective is not hypothetical — it is the pattern that existed before policy dismantled it.

The Planetary Health Diet — shown to reduce premature death risk by 30% — looks remarkably similar to traditional African dietary patterns: plant-centered, whole-food-based, rich in legumes and vegetables, minimal processed meat. Science is describing what African grandmothers already knew.

Food Sovereignty as the Actual Prevention Strategy

Individual dietary choice matters. But it is not the primary lever for addressing cancer disparities in Black communities. The primary lever is food sovereignty: the right of communities to define their own food systems, grow and distribute food according to their own traditions, and access the foods that their cultural knowledge and nutritional needs require.

Food sovereignty means community gardens in neighborhoods where fresh produce is inaccessible. It means supporting Black farmers and indigenous seed preservation. It means policy advocacy for food assistance that supports fresh food access rather than processed commodity distribution. It means honoring the ancestral knowledge of how to grow, prepare, preserve, and share food as a community practice rather than an individual consumption decision.

It means naming that when a community has higher cancer rates, the first question is not “what are they eating” but “what were they given access to, and who made that decision.” —MM
