Researchers reviewed five decades of how we grow and produce plant-based foods to understand how farming practices have changed over time. They looked at how these changes might affect both our planet’s health and the health of women who work in agriculture. The study examined trends in crop production, farming methods, and potential risks that have emerged as the food system has evolved. This comprehensive review helps us understand the bigger picture of where our plant-based foods come from and what challenges farmers and consumers might face in the future.

The Quick Take

  • What they studied: How plant-based food production has changed over the last 50 years and what risks this might create for the environment and for women working in agriculture
  • Who participated: This was a review study that analyzed existing research and data rather than conducting new experiments with human participants
  • Key finding: Plant-based food production has undergone significant changes over 50 years, with both benefits and emerging concerns for environmental sustainability and worker health, particularly for women in agricultural communities
  • What it means for you: Understanding how your food is grown can help you make more informed choices about what you eat and support farming practices that are better for both people and the planet. However, this is a broad overview, so individual food choices may vary in their impact

The Research Details

This study is a comprehensive review, meaning researchers looked back through 50 years of scientific literature, reports, and data about how plant-based foods are produced. Instead of doing new experiments, they gathered information from many existing sources to identify patterns and trends. They examined how farming methods, crop types, and production scales have changed from the 1970s to the 2020s. The researchers specifically focused on understanding both the positive developments in agriculture and the new problems that have emerged as farming has become more industrialized and widespread.

By looking at the big picture over a long time period, researchers can spot important trends that might not be obvious from single studies. This approach helps us understand the long-term consequences of how we produce food and identify areas where we need to make changes to protect both the environment and the people who work in agriculture.

This is a review article published in a peer-reviewed nutrition journal, which means other experts checked the work. However, since this is a correction notice rather than the full original article, readers should note that the complete findings and methodology details would be in the original publication. The broad scope of reviewing 50 years of data provides a comprehensive overview, though individual studies within that timeframe may have varying levels of reliability.

What the Results Show

The research shows that plant-based food production has changed dramatically over the past 50 years. Farming has become more mechanized and industrialized, with larger farms replacing smaller family operations in many parts of the world. Crop varieties have become more standardized, meaning fewer different types of plants are grown compared to the past. These changes have increased food production overall, helping feed more people. However, these same changes have created new challenges for environmental sustainability and for the health and safety of agricultural workers, particularly women who make up a significant portion of the agricultural workforce in many regions.

The review identified specific concerns including increased pesticide and fertilizer use, soil degradation, water usage challenges, and occupational health risks for farm workers. Women in agriculture face particular vulnerabilities including exposure to harmful chemicals, physical strain from repetitive work, and limited access to healthcare and safety protections. The study also noted that while some regions have adopted more sustainable practices, these improvements are not evenly distributed globally.

This comprehensive 50-year review builds on previous research by connecting individual studies into a larger narrative about how agriculture has evolved. It confirms what many smaller studies have suggested: that while industrialized agriculture has increased food production, it has come with environmental and social costs that we’re still learning to measure and address.

As a review article, this study depends on the quality of previously published research. Some regions and time periods may have better documentation than others, which could affect the completeness of the picture. The study covers a very broad topic, so it may not provide detailed information about specific crops, regions, or practices. Additionally, since this is a correction notice, the full scope of limitations would be detailed in the original article.

The Bottom Line

Consider learning more about where your plant-based foods come from and how they’re grown (moderate confidence). Support agricultural practices and companies that prioritize worker safety and environmental sustainability when possible (moderate confidence). Advocate for policies that protect agricultural workers and promote sustainable farming methods (moderate confidence). These recommendations are based on the overall trends identified in the research, though individual food choices involve many personal factors.

Everyone who eats plant-based foods should care about this research, as it affects the food supply chain. Consumers interested in sustainability and ethical food production will find this particularly relevant. Agricultural workers, policymakers, and farmers should especially pay attention to the findings about worker health and environmental impacts. People concerned about planetary health and climate change will find this research important for understanding agriculture’s role.

Changes in agricultural practices and their health impacts develop over years and decades. You won’t see immediate changes from individual choices, but collective shifts in consumer demand and policy can influence farming practices over 5-10 years. Environmental benefits from more sustainable practices may take even longer to become measurable.

Want to Apply This Research?

  • Track the source and production method of plant-based foods you purchase weekly. Note whether items are from local farms, certified sustainable sources, or conventional production. Over time, this helps you see patterns in your purchasing choices and their alignment with your values.
  • Use the app to research and identify 2-3 plant-based foods you eat regularly, then find alternative sources or brands that use more sustainable or fair-trade practices. Set a goal to switch to these alternatives for at least one food item this month.
  • Monthly, review your food purchases to track the percentage coming from sustainable or ethical sources. Set incremental goals to increase this percentage over time. Use the app to log which brands or farms you’re supporting and why, building awareness of your impact on agricultural practices.

This review article provides an overview of trends in plant-based food production over 50 years and should not be considered medical or nutritional advice for individual dietary choices. The findings represent broad patterns in agriculture and do not apply equally to all regions, crops, or farming operations. Individual health decisions should be made in consultation with healthcare providers or registered dietitians who can consider your personal circumstances. This is a correction notice; readers should consult the original full article for complete methodology and detailed findings. The research identifies concerns and trends but does not provide definitive guidance for personal food choices.
