Most of the food system conversation happens at the level of policy, science or capital. Erik Oberholtzer operates in a different register. He has built a metabolically conscious food business from scratch, taken it to scale, seen how growth can compromise founding values, and spent the years since figuring out how to protect them. His conclusions are more nuanced and more useful than most.
Tender Greens, which Oberholtzer co-founded in Culver City, California in 2006, was built on a single proposition: that fresh, organic, chef-driven food didn’t have to be expensive or exclusive. By the time he stepped back in 2020, the company had grown to more than 30 locations across California, New York and Massachusetts. The model worked. And it has since been replicated by Sweetgreen and Cava in the United States, and by Honest Greens, which opened recently in London.
But the fact that it can be done does not mean it is easy. Oberholtzer is specific about why California worked as a starting point – the climate, the proximity of farms, the ability to cut out distributors and buy direct. The conditions that made Tender Greens possible are not automatically transferable. The question is what it takes to create them elsewhere.
Oberholtzer is unambiguous on ultra-processed food (UPF). He has called it ‘poison’, and he stands by that framing. But his critique goes beyond the nutritional. The dominance of UPFs in the Western food system, he argues, is the result of consolidation, convenience and a cost calculation that systematically excludes the downstream consequences.
The true cost to planet and people is crazy
‘The true cost to [the] planet and people is crazy. Ultra-processed food is not ultimately a cheaper pathway. It is a lazy shortcut to a near issue of hunger, but a longer epidemic of food-related disease.’
He is equally clear that the problem is structural, not individual. The reason UPF is the default for millions of families is not that people prefer it – it is because the food system has been engineered to make it the path of least resistance. School lunch programmes, retail shelf space, marketing to children: the architecture of the food environment has been built by and for the processed food industry. Changing it requires more than consumer choice.
Oberholtzer’s most distinctive contribution to the Metabolica conversation is the connection he draws between agricultural biodiversity and metabolic health. He has spent years working to reintroduce heirloom crop varieties – older, often open-pollinated strains preserved over generations outside industrial cultivation – into the food system through the Crop Trust’s Spice of Life Project and the Agrobiodiversity Accelerator.
Oberholtzer’s argument is that the consolidation of the food supply around a narrow range of commercially optimised varieties has not just reduced flavour complexity – it has reduced the micronutrient diversity that a metabolically healthy diet requires.
Call it alchemy, call it romance, or back it up with science
‘If one has a diet that is incredibly diverse, not just in the type of food but the ingredients, the effect is compounded, both in flavour complexity and in micronutrients. Call it alchemy, call it romance, or back it up with science. You will find a better pathway to nutrition and ultimately health.’
Locality is the important point here. Just as a Pinot Noir from a specific hillside carries characteristics absent in a generic varietal of the same grape, an heirloom variety grown in specific soil carries micronutrient profiles that a mass-produced equivalent does not. At the level of a single piece of fruit, the difference may be negligible; across a lifetime of eating, it compounds.
On regulation, he is realistic without being defeatist. Washington has always been compromised by food industry lobbying. The more reliable lever is local and regional food systems that can scale through local movements, not top-down policy.
For investors and food brand leaders, Oberholtzer’s most actionable observations concern the mechanics of growth. His framework distils to five principles: 1) know your non-negotiable values and live them; 2) stay focused on the job you are doing for your consumer; 3) grow at a pace that preserves both; 4) maintain a financially and culturally healthy business; and 5) hold the vision clearly enough that the whole organisation can navigate obstacles without losing direction.
Outdoor clothing brand Patagonia is Oberholtzer’s benchmark model – a business that has made the environment its primary stakeholder and left money on the table rather than compromise that commitment. The underlying discipline – deciding what is non-negotiable before the pressure to compromise arrives – is transferable.
‘When the business takes over, oftentimes you lose your way. The pressures are real. But decide what is non-negotiable, and then hold the line.’
Oberholtzer’s perspective is a useful corrective to two failure modes that afflict the metabolic health conversation. The first is the assumption that the food system’s problems can be solved by consumer education and individual choice alone; the structural conditions that make UPF the default have to change as well. The second is the assumption that scale and integrity are fundamentally incompatible. They are not – but maintaining both requires a deliberate architecture of values that most businesses build too late, if at all.
For food manufacturers specifically, the implication is stark. The brands that will survive the coming regulatory, legal and reputational reckoning are the ones that decide now, not later, what they are not willing to compromise on. The ones that wait for the pressure to arrive will find, as Oberholtzer has observed in brand after brand, that by then the values have already faded.
