Only one theory can account for all of the available evidence: the obesity epidemic is caused by one or more environmental contaminants, compounds in our water, food, air, at our jobs and in our homes, that change how our bodies regulate weight.https://t.co/o7lhK2QkOL
It’s been established that our modern diets make it harder to lose weight, and keep that weight off. Yet, people who eat all natural foods tend to have the same problem as those with modern processed food diets, why? Thanks to a growing field of research we’re uncovering multiple theories, and perhaps the most promising is that chemicals in the water are the cause behind our dieting struggles.
A simple diet change reduced diet-related greenhouse gas emissions of American adults between 2003 and 2018. The carobon footprint of their diets fell from 4 kilograms of CO2 equivalent to 2.45 kg CO2e over the 15 year study period. All it took was a slight reduction in meat consumption.
As an individual one of the biggest things you can do in the face of climate change is to change your diet. It’s easy and saves you money!
The main reason for this decline emerged clearly in the data: over this same period, daily beef consumption plummeted by an average 40% per person, which accounted for nearly half of the diet-related dip in emissions. But it wasn’t just beef: the data showed a slow shift away from all animal-based foods, including dairy, eggs, chicken, and pork—all of which US citizens gradually consumed less of in 2018 than 2003.
This overall shift away from meat occurred slowly but steadily: on average, the food-related carbon footprint of US consumers declined by 127 grams each year of the study period.
We are what we eat, and right now many of us need to change who we are. Changing one’s diet can be one of the biggest things one does for the environment since we must eat everyday. Researchers have yet again shown that just removing red meat from your diet can make a big difference for the environment.
If removing meat from your diet is too much of a challenge then just reduce your consumption of it. Fighting climate change requires big groups of people making tiny changes so even doing a little can add up to a lot.
The team used a mathematical model that considered increases in population growth, income and livestock demand between 2020 and 2050. Under a business-as-usual scenario, the global increase in beef consumption would require the expansion of pasture areas for grazing and of cropland for feed production, which would double the annual rate of deforestation globally. Methane emissions and agricultural water use would also increase.
Replacing 20% of the world’s per-capita beef consumption with mycoprotein by 2050 would reduce methane emissions by 11% and halve the annual deforestation and associated emissions, compared with the business-as-usual scenario (see ‘Meat substitution’). The mitigating effects on deforestation are so great because, under this scenario, global demand for beef does not increase, so there is no need to expand pasture areas or cropland for feeding cattle, Humpenöder says.
Absolutely no one is shocked by new research that concludes beef is the worst thing to eat. If we’re going to feed billions of people on the planet while also having a livable planet for billions then we all ought to consume less meat. Raising cattle only to slaughter is a wasteful use of land that can otherwise feed way more people and cause a lot less damage to the environment.
The production of food makes up a third of greenhouse gas emissions so just by making a small change to your diet you can make it easier on future generations to survive. Eat less meat, eat more vegetables.
The researchers built a database that provided a consistent emissions profile of 171 crops and 16 animal products, drawing data from more than 200 countries. They found that South America is the region with the largest share of animal-based food emissions, followed by south and south-east Asia and then China. Food-related emissions have grown rapidly in China and India as increasing wealth and cultural changes have led more younger people in these countries to adopt meat-based diets.
The paperâ€™s calculations of the climate impact of meat is higher than previous estimates â€“ the UNâ€™s Food and Agricultural Organizationhas saidabout 14% of all emissions come from meat and diary production. The climate crisis is also itself a cause of hunger,with a recent study findingthat a third of global food production will be at risk by the end of the century if greenhouse gas emissions continue to rise at their current rate.
We are what we eat, and what we eat can change the world. All of us can make tiny changes in the kitchen to help reduce the harm modern food consumption does on the planet. Over at Eater they explore some ideas that people can try in their kitchen to improve their diet while also improving the planet. The really neat thing in this article is that it promotes us to learn from lockdowns during the pandemic when we all ended up making more home cooked meals.
Do what you can keep doing
Since the pandemic began, many of us have adopted efficient shopping and cooking practices out of necessity, but maintaining those habits post-pandemic could help make our lifestyles greener (and easier) in the long run. Look for stores reintroducing self-serve bulk sections and invest in quality food containers to continue saving money on ingredients in bulk, cut down on packaging, and reduce the number of trips to the store. Even if you return to the office, continue prepping meals on weekends and remain flexible with how you use ingredients to ensure you always have a decent meal after work. Clean the kitchen faster by integrating composting into your cooking routine, and reorganize your fridge to keep perishable ingredients visible to avoid food waste in the back. And pass down all these good habits to your kids, along with family recipes, to make them great helpers in the future.
