My Experience
I cannot thrive on a diet that lacks flavor, so I have learned to cook and bake delicious meals. To optimize my health and manage multiple allergies, I regularly experiment with and adjust my diet. Over time, I have refined my eating habits to align with both my health needs and ethical values. I hope this section helps you better understand the environmental and health impacts of different dietary choices.
Your Choices
We explore the latest scientific research and assess the greenhouse gas emissions associated with adopting a more plant-based, organic, and/or local diet. We also examine the effects of grass-fed beef and food waste. Additionally, we offer tasty, practical tips to help you make your diet greener and healthier.
Action Choices (with Links) | Climate Change Impact | Other Environmental and Personal Impacts |
Eat Plant-Based | 4+ tons/year (70% of diet) | Environmental Benefit; water use, water eutrophication, land use Health benefits: Reduced chance of heart disease, cancers, diabetes, high blood pressure, lung, liver and kidney diseases, Parkinson’s disease, etc. |
Choose Organic Foods | Fruits, vegetables: <=2/3 ton (20-25% of diet) | Environmental Benefit: Minimized water eutrophication, Maximized wildlife & pollinator survival Health Benefits: Reduced allergies/asthma, chance of cancer |
Reduce food discards | <=1 ton (30% of diet) | Benefits: Reduced cost and cooking Reduced food production reduces environmental impact of that particular food |
Eat Local Foods | <=1/3 ton (10% of diet) | Benefit: Reduced transportation Support for local business and farmers |
Grass-fed vs. Grain-fed beef Aquaculture Greenhouses | Not quantified, but scientific research is discussed | Research evaluates environmental impact of traditional versus alternative methods of farming. |
Calculate Your Impact
Use the spreadsheet under the tab: Calculate Your Footprint. This Excel spreadsheet enables you to easily estimate the greenhouse gases, water use, and land use for you and your family’s diet.
