Cows are easy to love. Their eyes are a liquid brown, their noses inquisitive, their udders homely; small children thrill to their moo. Most people like them even better dead. Americans eat three hamburgers a week, so serving beef at your cookout is as patriotic as buying a gun. In fact, of course, its authors were merely advocating a sensible reduction in meat eating.

Meat vs Veg: An energy perspectiveVIDEO ON THE TOPIC: How To Slice Every Fruit - Epicurious
More recent studies show that food system emissions could account for as much as quarter of all human emissions. This analysis tries to answer that question using data from the US. In it we compare five different diets:. Nor do we consider land use change emissions. For a Vegan it is even lower. But perhaps most interestingly, eating chicken instead of beef cuts a quarter of emissions in one simple step.
For a Meat Lover this rises to 3. Each of these estimates includes emissions from food that is eaten, wasted by consumers and lost in the supply chain. For the Meat Lover beef consumption causes almost half of emissions from just a tenth of food energy. In the No Beef diet all the reductions from the Average foodprint come by switching from beef to chicken.
The difference between the Vegetarian and Vegan diets arises from dairy consumption being switched to a mix of cereals and vegetables. Perhaps the most fascinating thing is that although the foodprints vary greatly, three fifths of each diet is identical.
The share that is constant accounts for kcal of food energy per day and about 0. So all the variation depends on the remaining 1, kcal per day. The Vegan gets these kcal for 0. This should not be confused with total food supply which is around 3, kcal each day. In each diet food energy is split up among nine different food groups. The five diets are all variations on the average diet. We assume the Meat Lover eats more red meat, white meat and dairy in place of some cereals, fruit and vegetables.
The No Beef diet is just the average diet with all beef consumption switched to chicken. The Vegetarian switches away from beef and chicken to fruit and vegetables, while also reducing oils and snacks. The Vegan does much the same as the vegetarian while also eliminating dairy through further switching to cereals, fruits and vegetables. The food energy that remains the same is each diet is roughly kcal of cereals, 80 kcal of fruit, 50 kcal of vegetables, kcal of oils, kcal of snacks and kcal of drinks.
The reason that these five foodprints vary so much despite being so similar is that the carbon intensity of food consumption differs greatly between the food groups. To estimate each foodprints we first calculated the carbon intensity of food consumption in each group. For a more complete explanation see our shrink your food footprint page.
These figures estimate the emissions produced in the process of supplying a kilocalorie of food energy for each food group. They show on average how carbon intensive it is for Americans to get their energy from the different food groups. Unsurprisingly red meat is the most carbon intensive way to get food energy, followed by dairy, fruit and chicken.
Cereals, oils and snacks are the least carbon intensive. These factors are the reason why foodprints gets smaller as less red meat, dairy and chicken are consumed. Although the carbon intensity of food production is the main driver in these figures, each is also influenced by how calorific foods are and what scale of supply chain losses and consumer waste they suffer.
For example oils, snacks and cereals are each highly calorific and have relatively low losses and waste, which results in them performing very well. The opposite is true of fruits and vegetables which are less calorific per unit weight but have a very high share of consumer waste and supply chain losses. Using food groups also hides great variation of carbon intensity within each group.
A hot housed tomato can have emissions 5 times higher than one grown in season, potatoes have tiny footprints compared to many other vegetables, and cheese has much higher emission than milk. So by limiting ourselves to just nine food groups we greatly understate the potential that changing diet has to reduce food emissions.
Such caveats aside, this analysis does highlight that a small share of the food we eat can cause the majority of our food emissions. Beef, lamb and cheese are among the most carbon intensive things we can eat, while milk, out of season fruit and other meats can also have relatively high emissions. Shifting some of your diet away from these foods towards cereals or in-season fruit and vegetables is a very effective way to shrink your foodprint.
Carbon footprint.. The numbers do not lie. It will be interesting to see if education or the onslaught of negative consequences is the final motivator; one can only hope that it is education, however I fear for the latter. It should be clear that all those farm animals farting and pooping will increase the carbon footprint for everyone.
A carbon footprint argument can be against keeping goldfish, a rabbit, or any pet. I found out while reading articles in Consumer Health Digest that there are in fact lots of ways safe practices in the meat industry. The human body can be vegan, but the types of plants required to sustain the body away from certain habitats cannot be done without supplementation or very expensive and eco-unfriendly agricultural practices used to bring non-native plants to places they cannot otherwise survive.
These hidden requirements, completely missed from the study, are a major contributor to energy consumption through transportation and general local energy consumption to sustain otherwise unviable crops locally were missed from this study. Drop meat, but embrace dairy and eggs if your body can tolerate them. Check it out please. Likewise, plenty of common plant foods are good sources of protein and calcium. Many dietetic authorities around the world have advised that well-planned whole-food plant-based WFPB diets are healthful for humans for all stages of life.
In fact, meat-based diets need to be as equally well planned as WFPB diets. I eat meat. I also only eat every one or two days, because I fast. My meals take minutes to cook and there is no waste, except for a small bone here and there which can be re-used to make a broth. I even walk to my supermarket, so I do not add car fuel to the air. I also, where I can, buy naturally raised meat that has no toxins.
There are many others like me. A vegan? Eat eat eat eat eat. Not to mention poop poop poop. Fruit and veg go rotten quickly so imagine for a moment how much is thrown out because someone not even vegans, just people who eat vegetables in general forgot to eat it. I viewed it only as one of the most decent references to calculate my efforts for CO2 reduction. Hello Lindsay, will you be creating a new article like this soon? I really loved this but it is getting pretty old.
I am wondering if the numbers have changed due to diet shifts, agricultural shifts, and more. It is very interesting! Thank you for the article. I took a different approach than most people here. I was interested in seeing my personal reduction of carbon footprint via fuel and food. Here are my results. Thank you for creating this, Lindsay. I have one thought I would like to plant with the you and readers: for the person who is a vegetarian, I challenge the notion that you can subtract ALL beef-related emissions from the diets of those consuming dairy.
High demand for dairy enables cheap beef and high consumption of that cheap beef. I get sick when I eat grains, I can only tolerate rice, rarely. This report is flawed as it does not include the growing movement of hunter gathers all over North America whom do not use any form of factory farming goods, this has been studied to be the lowest footprint of all in regards to food consumption because waste is almost completely eliminated. Hi, Like the article, very useful. Can you tell me if you are using short tons us or metric tons in the unit — t CO2e Thanks.
Once livestock respiration and the loss of greenhouse gas reductions from photosynthesis that are foregone by using large areas of land for grazing or feedcrops are taken into account, livestock is found to be responsible for 51 per cent of anthropogenic greenhouse gas missions.
I am moving to a region where legumes, soy etc. I would expect small wild game to be lower on the emissions output. Industrial meat farming is a horribly inefficient process, wasting, in particular a lot of water. Smaller farms are much more sustainable in that respect. What about the people working the farms, is the footprint of their lifestyle taken into consideration? Healthcare for the ongoing metabolic syndrome epidemic, root cause sugar, refined grains and vegetable seed-oils: obesity, T2D, cancer, heart-disease, cancer — needs to be taken into account.
Without the meat industry, billions of animals would never have been born. I would encourage you to try to publish your results in a peer-reviewed journal to if academic experts can certify your methodology. It would also give you a broader audience and might encourage more studies. Skip to content. Forget it France, move over Brazil. Paraguay is the greenest place on the planet to drive an electric car!

Processing and Preservation of Fresh-Cut Fruit and Vegetable Products
Authors: Wallace H. Andrews and Thomas S. Revision History: April Revised section A. The adequacy and condition of the sample or specimen received for examination are of primary importance. If samples are improperly collected and mishandled or are not representative of the sampled lot, the laboratory results will be meaningless. Because interpretations about a large consignment of food are based on a relatively small sample of the lot, established sampling procedures must be applied uniformly.

Chapter 8 Fruit specific preservation technologies. Contents - Previous - Next. Fruit quality goes back to tree stock, growing practices and weather conditions. Closer to the shipper and processor, however, are the degrees of maturity and ripeness when picked and the method of picking or harvesting. There is a distinction between maturity and ripeness of a fruit. Maturity is the condition when the fruit is ready to eat or if picked will become ready to eat after further ripening.
Plant-based meats sound healthy, but they’re still processed foods
Quorn is a meat substitute product originating in the UK and sold primarily in Europe, but is available in 18 countries. All Quorn foods contain mycoprotein as an ingredient, which is derived from the Fusarium venenatum fungus and is grown by fermentation. A vegan formulation also exists that uses potato protein as a binder instead of egg albumen.
By Afam I. Jideani, Tonna A. Anyasi, Godwin R. Mchau, Elohor O. Udoro and Oluwatoyin O. Fruits and vegetables are plant derived products which can be consumed in its raw form without undergoing processing or conversion. Fresh-cut fruits and vegetables FFV are products that have been cleaned, peeled, sliced, cubed or prepared for convenience or ready-to-eat consumption but remains in a living and respiring physiological condition. Methods of preserving FFV to retain its wholesomeness includes washing with hypochlorite, hydrogen peroxide, organic acids, warm water and ozone for disinfestation and sanitization; use of antimicrobial edible films and coatings; and controlled atmosphere storage and modified atmosphere packaging of fruits and vegetables.

The carbon foodprint of 5 diets compared
Mindful of the carbon emissions that come from raising cows, he orders a plant-based burger. He asks where this wondrous environmentally friendly virtueburger was made? Sheepishly, staff inform him that the patty—supplied by Beyond Meat, a California-based company—has been flown in from America. To be fair, Beyond Meat has plans to begin production of its foods in the Netherlands. A niche business is becoming mainstream. Startups and established food conglomerates are hungry for a share of a rapidly growing market for plant-based meats—foods that mimic the taste, texture and nutritional qualities of meat, without a single animal in sight.
On December 14, , amendments to nutrition labelling, list of ingredients and food colour requirements of the Food and Drug Regulations came into force. Regulated parties have a five 5 year transition period to meet the new labelling requirements. This section summarizes the labelling requirements that apply to imported meat products definition which includes poultry products , as well as those that are manufactured, processed, treated, preserved, graded, packaged or labelled in Canada for interprovincial trade and for export. In some cases, the labelling requirements would also apply when these products are intraprovincially traded.
