  • Yes. Because we live in a setting of specialists.

    I am no specialist at efficiently growing healthy food. So if I try it, it will be objectively worse than if someone else more proficient does it for me. And if that one is worse in doing something I am better in, we both are off worse and everything overall.

    So if we both would do things we are good at, the resulting products/services would be better, the processes would be more efficient (time, ressources, waste), which in return benefits all participants and the environment at the same time.

    Actually that is so efficient, it is possible to pay for the store’s rent, the wage of the people transporting, managing and selling that stuff to me. If I ineffectively grow my own food, all these are out of their jobs or have to (badly) grow their food at home, which they cannot afford anymore and they even do not have the necessary space for a field to do so.



  • You should shop by ingrediends and ecological reasons. That’s sadly not represented by $/g.

    The heavier product with the better “bang for the buck” is usually the one with the poorest quality and lots of sugar/additives/flavours/etc.

    Discounter products like “Great Value” can easily have a better quality than stuff produced by “Kraft” and other Unilever/Nestle/etc. products.

    Checking the ingredients list and the nutrition table should be a natural first instinct when grabbing something off the shelf.

    From Wikipedia:

    In a 2021 study published in the journal Plant Signaling & Behavior, Felipe Yamashita and Jacob White claimed that B. trifoliata may employ a primitive form of vision to identify and mimic their hosts. This hypothesis is based upon 1905 and 1907 claims by Gottlieb Haberlandt and Francis Darwin, respectively, that some plants use ‘ocelli’ or lens-like cells to focus light onto other light sensitive cells. In this study, B. trifoliata was observed mimicking the leaf shapes of plastic plants, and researchers refined Haberlandt and Darwin’s ocelli hypothesis, claiming that B. trifoliata may be using convex shaped lenses in epidermal tissue that can detect light and “see” the shapes of nearby leaves.[24] They further proposed that, B. trifoliata processes that information through an unknown means, possibly through neuron-like structures in order to initiate mimicry.[18][23] The study also found that non-mimetic leaves have more free-end veinlets and identified the hormone auxin as a possible mediator in changes to leaf morphology.[24]

    This paper received substantial media coverage, was praised by F1000’s Faculty Opinions, and went viral on the social media platform TikTok following its release. František Baluška, a plant biologist and editor-in-chief of Plant Signaling & Behavior, praised this hypothesis, and claimed that root skototropism and photoreceptive cells in algae were analogous mechanisms for “plant sight”. However, the paper’s conclusions have largely been met with skepticism by scientists. Criticisms of the paper include poor methodology, White’s lack of a scientific background, and possible conflicts of interest between Baluška and Yamashita.[18][23] The research was awarded the 2024 Ig Nobel Prize for botany.[25]
