Grocery Delivery Services: A Mixed Bag

This is a cross-posted blog from the Berman Institute of Bioethics’s Global Food Policy and Ethics (GFEPP) blog. It was written by Leslie Engel, MPH, a Science Writer Consultant for the GFEPP.

Americans have more ways than ever to shop for the ingredients needed for their meals. This was not always the case. Prior to the first self-service grocery store opening over a century ago, shoppers had to rely on clerks to retrieve and package items for them. Since then—aside from the invention of scanners and self-checkout—the grocery shopping experience has remained largely unchanged. It’s an industry ripe for disruption, and tech companies have seized upon this.

Enter grocery delivery services. These companies make lofty promises—to eliminate the hassle of grocery shopping, meal planning, preparation, and even the act of cooking itself—while also being good for you and the environment. And more Americans than ever are now using them.

I worked as a recipe manager for a leading grocery delivery startup whose mission is to make healthy eating easy by using artificial intelligence (AI) technology to predict customer food preferences. As a professionally trained chef with a background in public health, I was fascinated with the ability of such services to seamlessly deliver top-quality, nourishing, and sustainable products and recipes to customers, potentially as another avenue to improve health and wellbeing through home cooking. However, as I developed yet another recipe involving ground beef, I began to question how healthy this industry really is, both for ourselves and for our food system.

Convenience, for a price
Convenience, safety, and accessibility are the main appeal of these delivery services. This was especially evident during the COVID-19 pandemic, when many consumers turned to delivery to avoid in-person shopping. In theory, this means that more people will have better access to food, especially those with health, mobility, or other constraints. However, convenience comes at a price, and grocery delivery services pass this cost onto consumers in the form of markups, service, and delivery fees. Additionally, increased food costs due to inflation likely render this convenience financially out of reach for those most in need.

Reduction in greenhouse gas emissions?
There’s some evidence that grocery delivery could be more environmentally friendly than hopping into the car because it reduces greenhouse gas emissions. A study in Washington State demonstrated that it may be more efficient for a fully stocked truck to deliver to multiple households in the same neighborhood rather than individuals driving to the store themselves. But this is a best case scenario. The biggest emissions reductions would require households to cluster their orders together and forgo specific delivery times, thus reducing the convenience factor and the main selling point of such services.

Reliance on California’s Central Valley
Twenty-five percent of our nation’s food is produced in the Central Valley of California. The area is so integral to business that the company I worked for hired someone specifically from the region to oversee produce sourcing. But its agricultural future is in peril: water is scarcer than ever, severe droughts related to climate change have diminished groundwater stores and decimated crops, and intensive farming practices exacerbate the problem.

Crop failures or shortages were a huge sourcing and supply chain headache with trickle down effects. Customers often complained about receiving an inferior product, or one not as uniform as what they were accustomed to. Receiving a last minute vegetable “swap” presented a whole new set of customer challenges: I don’t like the cauliflower that replaced my broccoli! And how am I supposed to cook this?

The end result was often wasted food, as evidenced in the customer comments I analyzed. Food wasted at the household level is especially egregious because it squanders all the resources that went into growing, processing, packaging, and shipping it. In the U.S., between 73 and 152 metric tons of food is wasted somewhere along the supply chain annually. About half of that waste is happening at the household or food service level. And worldwide, food waste contributes 8% of human-generated greenhouse gas emissions, making it a significant contributor to climate change.

Technology
When customers rated a product or recipe, it became a data point used to further refine the AI, which then “decides” what product or recipe will go into their next delivery. You’ve no doubt seen the effectiveness of this technology in eerily relevant pop-up ads. Similar to how AI learns which ads you are most likely to click on, it can also learn which foods you’re going to enjoy or not. Like that hamburger? You shall receive more ground beef! It becomes a feedback loop designed to retain customers and increase profits, but not necessarily improve your health or the environment.

Looking Ahead
I still believe that grocery delivery services and the technology that drives them are the way of the future and can be a positive force within the food system. AI can potentially be used to improve diets, not just increase profits; researchers have harnessed this technology to help people grappling with obesity and diabetes to eat better.

To improve access for everyone, the U.S. government should make it easier for grocery delivery companies to accept Supplemental Nutrition Assistance Program (SNAP).The USDA is currently piloting a program that enables SNAP recipients to purchase groceries online from select retailers. Incentives should also exist for companies to waive delivery and service fees for SNAP recipients.

In addition, produce should be sourced regionally when possible. Shorter transit distances from farm to fridge mean less greenhouse gas emissions and fresher, more nutritious produce with a longer shelf life that’s less likely to be tossed. Fresh Direct offers a selection of local produce and more services should follow suit. The increased demand could help boost struggling regional agriculture and decrease demand on the imperiled Central Valley. Finally, the biggest thing missing from this new grocery shopping experience are people. AI may be “filling” your cart, but humans still harvest, process, pack and deliver everything we eat for low wages in unsafe working conditions. The pandemic has revealed that the meatpacking industry will go to great lengths–at the expense of humans–to maintain production and profits. Most recently, dozens of children were found to be illegally working as sanitation workers in meatpacking plants. By further alienating ourselves from where our food comes from, we’re less likely to see the value in the people behind the scenes making sure your fridge is full.

Food Bytes: Aug 26 - Aug 31

Food Bytes is a weekly blog post of “nibbles” of information on all things food and nutrition science, policy and culture.

Have you ever wondered which cuisine the world craves? Turns out, Italy. Yeah, no shit Sherlock. Italy is the largest exporter of their cuisine followed by Japan, Turkey and Mexico — Órale! Who is the largest importer, meaning, their food just sucks? You guessed it Sherlock. America. F!@#%* yah! China and Brazil don’t seem so keen on their local cuisine either. They follow the U.S. on importing other country cuisines. Funny. Brazil’s food based dietary guideline boasts harnessing its local cuisine. We guess people just don’t read those pesky guidelines…

Dari Mozaffarian and Dan Glickman wrote a timely op-ed piece in the New York Times that diets are now the number one risk factor killing Americans, costing the U.S. health care system billions each year. They provide a range of solutions and signify that governments and food and beverage industries need to be held accountable. While unhealthy diets continue to kill so many, politicians completely ignore the issue. As America moves towards what will be a contentious, decisive election year, they suggest that “every candidate should have a food platform, and every [presidential] debate should explore these positions.” Not sure this rhetoric will be high on the Trump “make American great again, for real this time” re-election campaign because the “Potus” just ain’t really that into food. Unless you consider consuming fast food a gourmand type diet.

Another op-ed piece in the New York Times by Catherine Kling urges that producers who cause “nutrient pollution,” in the form of nitrogen and phosphorus coming from agriculture fertilizer and manure run-off, should be required to pay for the cleanup. She suggests that state government regulations should be enforced to ensure that farmers reduce nutrient pollution. Wonder how livestock ranchers feel about that? Gee, take a guess.

IFAD and Bioversity just put out a great guideline on supporting nutrition-sensitive neglected and underutilized species (NUS) and wild edibles (check out Figure 2 particularly). The guideline is led by the great Stefano Padulosi at Bioversity who has some deep experience working on NUS value chains in many parts of the world. He is also the “Rocket Man.” What are NUS you ask? Here is how they define it in the guideline:

Many are the synonyms which have been used since the mid-1980s to refer to NUS, including minor, under-used, under-exploited, under-developed, orphan, promising, lost, alternative, traditional, niche crops, crops of the future, future smart food. In reality, all these terms are often context-specific and loaded with heavy cultural meanings and not easily understood in the same way by everybody. The term “Neglected and Underutilized Species” might not be the ideal expression and may not be appealing to people.

There is so much focus these days on diet and the food system footprints on climate change. It is seriously having its moment. But in the back of our mind’s eye, we hark back to an article published in 2017 in Environmental Research Letters, that indicated that largest impact an individual can make to reduce their greenhouse gas footprint is to have one less child. Check out this graphic to the right. Powerful. This action is followed by living car free. Diet is further down the list of impacts. Food for thought…

Interestingly, they didn’t model reducing food waste by individuals. The World Resources Institute (WRI) has just released a global action agenda on reducing food loss and waste by 2030. It is a really practical guide to setting targets, honing in on who should take action and what scalable interventions are available. Everything WRI puts out is pretty stellar and this is another data rich, practical guide to tackle one of the most important issues of the food system.

What if all Americans ate less meat? Not necessarily eliminating meat completely, but just much less? By the way, American are already slowly and steadily decreasing their beef consumption since the 1980s. In the Nature journal Scientific Reports, scientists tested this idea. By replacing 25% meat with plant alternatives dominated (strangely) by soy, green pepper, squash, buckwheat, and asparagus, Americans can eliminate pastureland use while saving 35–50% of their diet related needs for cropland and 330 million metric tons of greenhouse gas emissions each year, but increase their diet related irrigation needs by 15%.

These advertisements on the left for PETA Vegan guides are all over DC (note the elephant in the background just to remind you that yes, DC is the capitol of the U.S. and the district lives and breathes politics. You can’t get away from it. It will smother, suffocate and slowly destroy you). Where were we? Oh yeah. We picked up the guide and thumbed through it. Some of the recipes didn’t look so tantalizing, and much of what was recommended wasn’t all that healthy. There were lots of photos of faux meat mimicking fried chicken fingers, hotdogs, and meatballs doused in sticky sauce, as well as lots of cakes. Is it possible to promote sustainable, healthy, and animal cruelty free vegan diets for those who choose to go that route PETA? That can’t be too hard can it? While it was an A for effort, maybe version 2 of the guide will feature more healthy foods and less overly processed, junk food.

In other news, with Uber Eats and other gig economy food deliveries on the rise, so is the toll on the drivers delivering food. They are risking their lives in places like South Africa. Tragic. And just to deliver the ultimate convenience to our dinner table.

Venezuela. Talk about a free fall into despair and chaos. Because of the turmoil, food security and the deeper issues of consistent insecurity have taken a big hit. Venezuelans lost an average of twenty-four pounds in body weight. Nine out of ten live in poverty. Roughly one in ten have left the country.

A paper just published in the Lancet hits right at the heart of the trade war between the U.S. and China. The authors feel that it is time to reshape trade policies towards those that favor sustainable food and nutrition systems. They argue there are three starting points for public health actors to take up this agenda.

  1. Recognize the fundamental and front-line nature of trade policy as both a barrier and potential catalyst for health.

  2. Engage more effectively and with the right stakeholders to push for policy space within trade and investment agreements.

  3. Reach beyond trade to promote a development discourse that makes explicit the nutrition imperative — nutrition is crucial to achieving most of the Sustainable Development Goals.

The Food Archive holds a special place in its heart for special focus issues that scientific journals put out. That is, when journals hone in on a hot topic and publish a complementary set of articles on the topic to show different facets and perspectives on the topic.

Here are some recent highlights:

In the last food bytes post, the hard to watch unfold Brazilian Amazon fires were highlighted. This piece highlights that forest fires are happening all over the world, many in biodiverse hotspots, making climate change all that much worse. Very sad not only for forests but for those who live among and depend on them. The map on the right shows fires over the last year. Look at southwest Africa and Southern Africa. Look at Madagascar (think lemurs…) and Southeast Asia. Wah!!

One place prone to massive forest fires (the 2018 fires were the most devastating in the state’s history) is California but every day it finds a way to rub its beauty in our face. Geez, okay Cali, you win.

Speaking of California, and to keep the whole Woodstock vibe going, let’s just end with a little Joni Mitchell, because she sings about omelets and stews and well, because this has to be one of the best albums ever recorded. Click below to hear her beautiful song, California.

Oh the rogue, the red red rogue
He cooked good omelets and stews
And I might have stayed on with him there
But my heart cried out for you, California
Oh California, I'm coming home
Oh make me feel good rock'n roll band
I'm your biggest fan

California, I'm coming home

— Joni Mitchell

 

 

Food Bytes: Weekly Nibbles from Jan 1 - 7

Food Bytes is a weekly blog post of “nibbles” of information on all things food and nutrition science, policy and culture.

As the world slowly wakes up to a new year, there are already some interesting food nibbles published this week.

Great commentary in Lancet Planetary Health on a new, longitudinal study being led by researchers at the Australian National University to understand the relationship between culture and health of the Aboriginal and Torres Strait Islander people, a group of indigenous peoples who have been discriminated against, underserved and disrespected for too long. The study is actually being designed BY and WITH Aboriginal and Torres Strait Islander people and will gather comprehensive data to explore the links between land, culture, and health amidst the “backdrop of an evolving human civilization and changing state of planetary health.” Looking forward to seeing the results and the transferability of the research to other indigenous peoples.  

In light of the frightening IPCC report on climate change, the Washington Post asked activists, politicians and researchers for 11 climate policy ideas that offer hope. Two involve food. One is about cutting the food we waste in half and is a “win-win-win-win-win for waste mitigation, jobs, economic activity, food security and of course, the climate.” The second is reducing the expansion of CAFOs - concentrated animal feeding operations, and instead, supporting smaller-scale farmers practicing sustainable grazing practices, expanding the infrastructure for grass-fed beef and dairy markets, and enforcing fair market and fair contract rules for the livestock industry.

The Lancet published a very short piece on how digital technologies may revolutionize nutritional sciences. One big gap in the science is that we do not know what people eat, and for everyone who does eat (which is everyone…), we have no way of tracking the health of those foods without going through a very laborious process. Now, with the advancement of technology, we may be able to carry our own personal nutritionist in our pocket, that is, through our smart phones. “By synchronizing various health data types from multiple sources, such as wearable sensors, electronic health records, metabolic profile, gut microbiome, and diet, all analyzable in real-time using machine or deep-learning algorithms, a person’s smartphone has the potential to function as a digital nutritionist.” I am particularly keen to see how the photo-based dietary tracking through automated food image recognition that determines calorie and nutritional content will work.

Gerald Nelson and colleagues published a Nature Sustainability paper and a follow-up op-ed piece in the Washington Post that the global agriculture sector’s narrow focus on feeding the world, in the form of carbohydrate calories (mainly maize, rice and wheat), has led us and will continue to lead us down a dangerous path. In their study, they found that there will be more than enough food per capita to feed 10 billion people by 2050, even with the business as usual climate change pathway. They argue that the focus on carbohydrates has been a contributor to the rising rates of obesity and continued micronutrient deficiencies. They recommend that agriculture shift gears and increase production of major nutrient-rich foods such as fruits, vegetables, nuts, seeds and beans instead of the forty-year focus on staple grains.
