Understanding the Link Between Ultra‑Processed Foods and Chronic Disease

A landmark study published in The BMJ in 2024 has drawn a powerful connection between ultra‑processed food (UPF) consumption and a wide array of adverse health outcomes. Titled “Ultra‑processed food exposure and adverse health outcomes: umbrella review of epidemiological meta‑analyses,” the study provides a comprehensive evaluation of existing meta‑analyses on the topic, bringing new clarity to a rapidly growing field of research.

At Healthspan Longevity, we emphasize optimizing long‑term health through proactive testing, personalized insights, and science‑backed interventions. This study reinforces the need to minimize UPF intake to prevent disease, extend healthspan, and optimize key biomarkers through lifestyle‑first strategies.

What Are Ultra‑Processed Foods?
The study categorizes foods using the NOVA food classification system, which divides foods into four groups based on the extent and purpose of processing. Ultra‑processed foods (Group 4) include industrial formulations with little to no intact whole foods. They are often high in added sugars, unhealthy fats and artificial additives, and designed for hyper‑palatability.

Common UPFs include:

  • Sweetened breakfast cereals

  • Snack bars and chips

  • Soft drinks and energy drinks

  • Packaged baked goods

  • Flavored yogurts with additives

  • Instant noodles and frozen meals

These products are typically energy‑dense and nutrient‑poor, disrupting hunger cues and metabolic regulation.

The Scope and Strength of the BMJ Study
This umbrella review synthesized data from 45 pooled analyses across 14 meta‑analyses, involving over 9 million participants. Using the GRADE system to assess quality of evidence, researchers determined the strength and credibility of associations between UPF consumption and various health risks.

Key Findings:

  • Cardiometabolic Disease
    • Obesity: High UPF intake was strongly associated with increased risk of overweight and obesity.
    • Type 2 Diabetes: A consistent link was found between UPF consumption and elevated risk of insulin resistance and diabetes onset.
    • Cardiovascular Disease: Evidence indicated a moderate to strong association with coronary artery disease and hypertension.

  • Mental Health and Cognitive Decline
    • Depression and Anxiety: Higher intake of UPFs correlated with increased incidence of mood disorders.
    • Potential Cognitive Impact: Though less conclusive, some studies indicated risk of cognitive decline linked to poor diet quality, which includes high UPF consumption.

  • Cancer and Mortality
    • Cancer: Increased risks were found for colorectal and breast cancer, with biological plausibility tied to pro‑inflammatory ingredients and endocrine‑disrupting additives.
    • All‑Cause Mortality: High UPF consumption was associated with a marked increase in overall mortality.

Study Limitations
While this umbrella review offers a robust synthesis, several limitations should be noted:

  • Observational Nature: The included meta‑analyses are observational, so causality cannot be definitively established.

  • Confounding Variables: Lifestyle factors like physical activity, smoking and socioeconomic status may have influenced results.

  • Dietary Assessment Limitations: Self‑reported food intake data can introduce measurement errors.

  • Heterogeneity Across Studies: Different definitions and classifications of UPFs may affect consistency.

Despite these limitations, the strength and consistency of the associations across diverse populations lend significant weight to the study’s findings.

Why This Matters for Healthspan Optimization
At Healthspan Longevity, we do not benchmark against “normal” ranges defined by population averages. Instead, we align all recommendations with optimal healthspan ranges that correlate with lower chronic disease risk and enhanced physiological resilience.

The biomarkers most impacted by UPF intake include:

  • ApoB: A primary indicator of atherogenic lipoproteins and cardiovascular risk.

  • Triglycerides and HDL‑C: Affected by diet quality and linked to insulin sensitivity.

  • HbA1c and fasting glucose: Reflective of glycemic control and metabolic health.

  • CRP (C‑reactive protein): A marker of systemic inflammation exacerbated by poor diet.

  • Vitamin D and homocysteine: Tied to inflammation, methylation and cardiovascular integrity.

Clients with suboptimal ranges in any of these markers are often advised to assess their dietary patterns in light of the NOVA classification system. Reduction of UPFs is frequently our first‑line intervention.

Implementing the Science: Our Approach

  1. Blood Biomarker Testing
    We monitor over 60 biomarkers, including lipid subfractions, inflammatory markers, glycemic control indicators, micronutrient levels and hormone balance. Many of these are adversely affected by frequent UPF consumption. Early identification allows for personalized, food‑first interventions.

  2. Nutrition Coaching Based on NOVA Principles
    Our team educates clients on how to:

    • Identify ultra‑processed foods using ingredient lists and food labels

    • Replace UPFs with minimally processed alternatives

    • Build meals from whole, NOVA Group 1 foods such as legumes, vegetables, fruits, whole grains and seeds

  3. Prioritizing Protein and Fiber Intake
    Adequate, high‑quality protein is essential for preserving lean mass, supporting metabolic rate and improving satiety. We help clients meet optimal protein targets with:

    • Legumes, lentils and tofu

    • Eggs and plain Greek yogurt

    • Fish, poultry and lean meats

    • Supplemental support if medically indicated (e.g., in sarcopenic risk)

    Alongside protein, we emphasize fiber‑rich whole foods, aiming for 30–40 g of daily fiber to improve glycemic control, lower ApoB and support gut health. Top sources include chia and flaxseeds, avocados and leafy greens, lentils and chickpeas, and oats and berries.

  4. Resting Metabolic Rate and VO₂ Max Testing
    These tests inform us about caloric needs and cardiorespiratory fitness. High UPF diets are known to impair metabolic flexibility and exercise capacity, two key pillars of longevity.

  5. Cognitive and Sleep Assessments
    Mood and cognitive function are closely tied to dietary quality. Clients undergoing cognitive testing or sleep apnea screening often benefit from dietary shifts that reduce neuroinflammation, including lowering UPF intake.

  6. Movement and Exercise Guidance
    Exercise is a cornerstone of the Healthspan Longevity philosophy. Physical activity supports metabolic health, preserves lean body mass and improves cardiovascular resilience. Our programs integrate strength training and aerobic conditioning tailored to biomarker and VO₂ max data.

Practical Strategies

  • Reframe Convenience: Many UPFs are chosen for convenience. We help clients build fast, nutrient‑dense meals using pre‑chopped vegetables, frozen fruits and batch‑cooked legumes— all minimally processed.

  • Use Data to Stay Accountable: Biomarker tracking is the ultimate feedback loop. Clients who reduce UPF intake and focus on whole foods often see tangible improvements in lipid profiles, inflammation and energy levels within weeks.

  • Optimize Protein, Fiber and Exercise Together: We encourage clients to anchor each meal with a protein source, boost fiber through plant diversity and pair dietary improvements with consistent movement.

The Bigger Picture: Public Health and Policy
This study aligns with global calls to reduce UPF availability and marketing. At the individual level, it underscores that dietary choices powerfully influence healthspan.

At Healthspan Longevity, we go beyond generic advice to deliver data‑driven, personalized health optimization, using tools like advanced blood testing, RMR analysis, DEXA scans and evidence‑based nutrition guidance. Minimizing ultra‑processed food is not a fringe idea—it’s foundational.

For those looking to extend both lifespan and quality of life, the evidence is clear: whole foods are medicine, and ultra‑processed foods are a risk multiplier. Use the science to take control.
