What counts as a basic need — and what doesn't

Start here, because everything else in this course assumes you can tell a real need from a manufactured one. The word 'need' gets used to sell things. It also gets used by clinicians and public-health bodies to describe conditions a human actually requires to function. Those are not the same word.

A field skill: when you're cold and wet at altitude, the difference between 'I want a dry layer' and 'I need a dry layer' is the difference between discomfort and a survival problem. The wellness industry blurs that line on purpose. This chapter is about un-blurring it.

Two camps of 'need'

Evidence-based needs come from population-health research and clinical observation. They have validated measurement instruments, peer-reviewed outcome data, and authoritative bodies that update guidance as evidence accumulates. They tend to be boring: enough calories, enough movement, enough sleep, enough contact with people who know you.

Industry-driven 'needs' come from someone with a product to sell. The marker is usually that addressing the 'need' requires you to buy a specific thing — a supplement, a protocol, a subscription, a piece of equipment that looks impressive in a kitchen. The outcome data is thin or absent. The endorsement comes from a celebrity, a podcast, or a TikTok, not from a guideline body.

Where the line lives — five markers

• There's a validated short instrument that measures it (PHQ-2, GAD-2, USDA DRI calculator, AASM sleep screen, UCLA-3 loneliness scale, etc.)
• There's an authoritative body that publishes a guideline about it (CDC, NIH, USDA, USPSTF, WHO, Cochrane, NICE)
• The outcome data appears in peer-reviewed journals indexed in MEDLINE — not just on the producer's website
• The guideline body updates the recommendation as new evidence arrives, not as new sponsorships do
• The intervention doesn't require buying one specific company's product to address

The wellness-industry markers (five anti-patterns)

• Addressing the 'need' requires a specific purchase — a supplement, a protocol, a subscription, a device
• The endorsement comes from a celebrity, an influencer, or a podcast — not from a guideline body or clinical society
• The outcome claim is based on a single study, often industry-funded, often not replicated
• The 'before/after' photos do the work that the data should be doing
• The framing implies your doctor is hiding this from you — the conspiracy frame is the tell

The seven dimensions we'll cover

Chapter 2 walks each dimension end-to-end with a validated short-form instrument. The dimensions are drawn from Healthy People 2030's social determinants frame, the WHO International Classification of Functioning, and the major US clinical society guidelines (one society per dimension):

• Food adequacy — USDA Dietary Guidelines, USDA DRIs
• Movement — ACSM Physical Activity Guidelines
• Sleep — AASM sleep duration + quality recommendations
• Mind — USPSTF depression / anxiety screening (PHQ-2, GAD-2)
• Connection — UCLA-3 loneliness scale; CDC social-connectedness reports
• Sense / pain — AAFP pain red-flag screening
• Function — CDC STEADI fall-risk screening; AGS ADL assessment

That's the frame. Evidence-based needs map to indicators a public-health body actually tracks. Wellness-industry 'needs' rarely do. When you can't find a Healthy People indicator (or a USPSTF recommendation, or a Cochrane review) on a topic, that's information by itself.
