The three costs
Health — the cost to your body
A label can carry a nutrition panel, an ingredient list, and sometimes a claim. Those are a starting point, not a verdict. A package statement is Reported until you check it, and how a food fits your body, history, and needs is not something a shelf can answer.
What you can usually see: the ingredient list and, on many packaged foods, the required nutrition facts. What stays Unknown at purchase: how it interacts with the rest of your week, your particular health situation, or a specific outcome. Those belong with a qualified professional, not a label and not this page.
Middle-path question: What can I actually read here, and what am I assuming?
Carbon — the cost to the living world
This is the axis where confident-sounding claims are least supported. A photo of a field, a leaf on a wrapper, or the word “eco-friendly” does not establish a footprint. The Federal Trade Commission warns marketers not to make broad, unqualified environmental-benefit claims precisely because they are so hard to substantiate, and recommends clear, specific qualification instead.
What you can sometimes see: a specific, qualified claim tied to a named program or a stated method. What stays Unknown at purchase: the actual emissions behind most products, which are rarely disclosed in any checkable form. A broad green claim with no basis is Unknown, not Verified.

Middle-path question: Does this claim say what was measured — or just feel green?
Cost — the price you pay
This is the honest one. Of the three costs, financial cost is the one you can most often actually verify at the shelf: the price is printed, and unit pricing — where it appears — lets you compare per ounce or per item rather than per package.
What you can usually see: the price, and often the unit price. What stays Inferred or Unknown: the fuller cost — how much you will waste, how long it lasts, cost per actual use. Those are reasoned estimates at best, not facts on the tag.
Middle-path question: Am I comparing price, or comparing unit price and likely waste?
