Concidering the amount of energy required to produce animal-based foods and goods, should humans change their habits so they consume products closer to the bottom of the food chain because it is more efficient?

It would be a good idea if more people did that

To evaluate whether humans should change their habits to consume products closer to the bottom of the food chain for efficiency reasons, let's consider a few factors:

1. Energy Efficiency: It is true that animal-based foods require more energy to produce compared to plant-based foods. This is because animals consume plants for their growth, and energy is lost at each trophic level. So, consuming products lower on the food chain can potentially be more energy-efficient.

2. Overall Resource Use: Producing animal-based foods not only requires more energy but also utilizes vast amounts of land, water, and other resources. Plant-based foods typically have a lower environmental footprint since they require fewer resources for cultivation.

3. Nutritional Needs: While consuming products closer to the bottom of the food chain can be more energy-efficient, it's crucial to consider nutritional requirements. Animal-based foods often provide essential nutrients like complete proteins, vitamins, and minerals. However, with careful meal planning, a well-balanced plant-based diet can also meet nutritional needs.

4. Personal Choices: Changing dietary habits is a personal decision influenced by factors like cultural, ethical, and health considerations. While energy efficiency and environmental impact are important, individuals have varying priorities and dietary preferences.

Considering these points, if one is concerned about energy efficiency, environmental sustainability, and can meet their nutritional needs with a plant-based diet, gradually incorporating more plant-based foods into their diet can be a positive step. However, it's essential to consult with a healthcare professional or registered dietitian to ensure a balanced intake of nutrients.

If you're interested in determining the energy efficiency or environmental impact of different foods, you can refer to studies or databases that provide life-cycle assessments for specific products. These assessments take into account factors such as energy use, land use, water consumption, and greenhouse gas emissions throughout the entire production process, which can help inform your decision-making process.
