Blood pressure “normal numbers” changed: what the Instagram post gets right and wrong
A verified Instagram post from Suzana Pavlovic / msglucoseofficial says “normal” blood-pressure numbers changed from 160/95 in 1970 to 140/90 in 1985 to 110/70 in 2026. The useful question is real: thresholds and treatment targets have changed. The exact graphic is too simple.
Short answer
Partly true, but misleading as written. It is true that hypertension definitions and treatment targets have shifted lower over time as observational and trial evidence linked lower pressures with lower cardiovascular risk. It is also true that metabolic health, body weight, diet, activity, sodium, alcohol, sleep, kidney/RAAS factors and insulin resistance can all matter. But 110/70 is not the universal “normal blood pressure” cutoff in 2026. Canada.ca says levels lower than 120/80 are considered normal; AHA uses normal as below 120 and below 80; Hypertension Canada 2025 defines hypertension at ≥130/80 under standardized conditions and recommends a treatment target of systolic <130 when tolerated.
What the post claims
The image says: “They changed the blood pressure numbers… again,” then lists 1970: 160/95, 1985: 140/90, 2026: 110/70. The caption asks whether people are getting healthier or whether high blood pressure affects bodies earlier than once thought, then points to insulin resistance, chronic inflammation, nutrition, movement and lifestyle factors. It ends with a “comment BP” protocol offer.
Claim table
| Claim | Finding |
|---|---|
| Guidelines changed over time. | Supported. AHA/ACC, Hypertension Canada and historical literature show definitions/targets have shifted. |
| 1970 normal was 160/95. | Oversimplified. Older treatment/acceptability thresholds were higher, but PBC did not verify a universal official 1970 “normal = 160/95” standard. |
| 1985 normal was 140/90. | Partly supported but imprecise. 140/90 became a major hypertension threshold/target, not necessarily a “normal” ideal. |
| 2026 normal is 110/70. | Misleading. Public guidance commonly says normal is below 120/80; Canada and AHA do not make 110/70 the universal normal cutoff. |
| Insulin resistance can matter. | Research kernel. Insulin resistance and metabolic syndrome correlate with hypertension risk, but reviews caution the mechanism is complex and not “insulin alone.” |
| An Instagram protocol can replace medical care. | Unsupported and unsafe. Lifestyle matters, but blood-pressure diagnosis and treatment decisions need proper measurement and clinical context. |
What current sources say
Canada.ca says more than one reading is needed because blood pressure varies, home readings matter, and levels below 120/80 mmHg are considered normal. It also gives practical measurement instructions and lists prevention steps including salt reduction, physical activity, healthy weight, smoking cessation, stress management and limiting alcohol.
Hypertension Canada’s 2025 primary-care guideline recommends standardized measurement, out-of-office confirmation where possible, defines hypertension as BP ≥130/80 under optimal validated measurement conditions, recommends healthy lifestyle changes for all adults with hypertension, starts medication at ≥140/90 and at 130–139 systolic for high-risk adults, and targets systolic BP <130 if tolerated.
Metabolic-health kernel
The caption’s root-cause instinct is not wrong. Insulin resistance, obesity/metabolic syndrome, sodium intake, activity, alcohol, kidney function, sympathetic nervous-system activity and RAAS physiology can all be relevant. But the insulin-resistance literature is more nuanced than Instagram slogans: reviews report correlations, while also saying insulin resistance/hyperinsulinemia may not be the main initiating cause of hypertension in humans.
