Long-term adherence to a prescribed low-sodium diet is poor in
heart-failure patients, the population where the medical case for
restriction is unambiguous, where adherence is professionally
counseled, and where the cost of exceeding the limit is
hospitalization. Chung et al.’s peer-reviewed cohort documents this
directly: patients classified as non-adherent excreted about 4,135 mg
of sodium per day on objective 24-hour urinary measurement versus
about 3,086 mg among adherent patients. Pooled objective-adherence
rates across this broader literature run roughly 20-40%, implying that
the majority exceed their limit; we take a ~70% lapse rate as the
action-side proxy midpoint, not a figure reported by any single study.
That proxy is used because no published study asks “do you
regret going on a low-sodium diet?” head-on. Healthy US adults
attempting voluntary reduction without clinical pressure almost
certainly lapse at higher rates, not lower. Lapsing is not regretting:
some lapsed because food became unpalatable, some because of social
and family meals, some because they concluded the benefit was not
worth the sacrifice. The He, Li & MacGregor 2013 Cochrane meta-analysis
in BMJ — 34 trials, 3,230 participants — established that modest salt
reduction lowers systolic blood pressure by 5.39 mm Hg in hypertensives
and 2.42 mm Hg in normotensives, so the intervention itself delivers
real (if modest) benefits when sustained.
On the other side, 47.7% of US adults have hypertension per
CDC NCHS Data Brief No. 511 (Oct 2024), based on NHANES August 2021
August 2023 measurement data — a downstream clinical state that
excess sodium intake partly causes, used here as the inaction-side
proxy. This figure also falls short of a direct regret measure: many
of the 47.7% have never made the connection between their salt
intake and their blood pressure, and many of the 52.3% without
hypertension might still regret their salt habits for other reasons.
Hypertension has multiple causes (genetics, age, weight, alcohol,
sodium, physical activity); sodium is one contributor among several.
The two figures come from different instruments (clinical adherence
cohort vs federal surveillance survey) and measure different
constructs (behavioral abandonment of a prescribed regimen vs current
clinical state), so the apparent 1.5:1 action-to-inaction ratio
overstates the precision of the cross-side comparison. The American
Heart Association’s standing dietary guidance — no more than 2,300
mg/day with an ideal target of 1,500 mg/day — sits well below the
measured average US intake of roughly 3,400 mg per day.
The SSaSS NEJM 2021 cluster trial of 20,995 rural Chinese adults
provides the strongest hard-endpoint evidence on the inaction side:
switching from regular salt to a potassium-enriched substitute
reduced stroke by 14%, major cardiovascular events by 13%, and
all-cause death by 12% over 4.7 years. The Mente et al. 2016 Lancet
pooled analysis of PURE and three other cohort studies (133,118 adults,
49 countries) reported a U-shaped association with apparent excess
cardiovascular risk below ~3,000 mg sodium per day
— that finding is contested for methodological reasons (single-spot
urine with the Kawasaki formula) and is not currently reflected in
the AHA or WHO guidelines, but it is the cleanest published basis
for the J-curve concern at the lowest intake range. The
action-dominates pattern reflects the asymmetry between a very high
prescribed-diet lapse rate and a substantial but lower share of US
adults already living with the downstream condition the diet is
meant to prevent. Both figures are proxies for different constructs
(behavioral abandonment vs current clinical state), so the delta
should be read with caution.

Cálculo
Chung et al. (Western Journal of Nursing Research 2017) is the leading peer-reviewed cohort analysis of long-term low-sodium diet adherence in a population where the medical case for restriction is unambiguous (heart failure). Pooled long-term adherence rates in this literature run roughly 20-40% by objective 24-hour urinary sodium measurement, implying that 60-80% of patients exceed their prescribed limit despite professional counseling and clear motivation. We use the midpoint ~70% lapse rate as the action-side proxy. This is NOT a regret measure. The figure overstates the relevant population — most US adults considering a low-sodium diet do not have heart failure, so the motivational and counseling intensity that still produces ~70% lapse in HF patients is an upper bound on what a typical US adult would sustain. Among healthy adults attempting voluntary sodium reduction without clinical pressure, lapse rates are almost certainly higher than 70%, not lower. The figure brackets the direction (most attempts at sodium reduction fail to sustain) without isolating a regret signal: some lapsed because the food became unpalatable, some because of social and family meals, some because they concluded the benefit was not worth the sacrifice.

[2]BMJ / He, Li & MacGregor — Effect of longer term modest salt reduction on blood pressure: Cochrane systematic review and meta-analysis of randomised trials
Verificado
Revisado por pares
34 trials, 3,230 participants; modest salt reduction lowers systolic BP by 5.39 mm Hg in hypertensives and 2.42 mm Hg in normotensives
Trecho
“"in people with hypertension the mean effect was -5.39 mm Hg (-6.62 to -4.15, I(2)=61%) for systolic blood pressure and -2.82 mm Hg (-3.54 to -2.11, I(2)=52%) for diastolic blood pressure. In normotensive people, the figures were -2.42 mm Hg (-3.56 to -1.29, I(2)=66%) and -1.00 mm Hg (-1.85 to -0.15, I(2)=66%), respectively. A modest reduction in salt intake for four or more weeks causes significant and, from a population viewpoint, important falls in blood pressure in both hypertensive and normotensive individuals, irrespective of sex and ethnic group."

Cálculo
He, Li & MacGregor (BMJ 2013) is the canonical Cochrane meta-analysis underpinning current sodium-reduction guidelines. Provides the action-side evidence that the intervention itself produces real (if modest) blood-pressure reductions, especially in hypertensives. Used here as the peer-reviewed basis for the clinical rationale to attempt sodium reduction; not the source of the 70% lapse rate (that is from Chung et al. 2017). The magnitude of the BP effect is small in normotensives, approximately -2.4 mm Hg systolic, which weakens the regret- avoidance case for adherence pressure on people without hypertension.

The 47.7% headline is rounded to 48% in our regret_rate field for display, since the data brief explicitly notes consistency with the prior 48.1% figure from 2017-March 2020. We use that as the inaction-side downstream-risk proxy. This is NOT a regret measure about salt habits. Hypertension has multiple causes (genetics, age, weight, alcohol, sodium, physical activity), and sodium is one contributor among several. Many of the 47.7% have never made the connection between their salt intake and their blood pressure, and many of the 52.3% without hypertension might still regret their salt habits for other reasons. The figure brackets the downstream-cost direction without isolating a regret signal. Sample N=6,084 for the prevalence analysis.

Neal et al. SSaSS (NEJM 2021, presented at ESC 2021), cluster- randomized trial of 20,995 rural Chinese adults with prior stroke or hypertension. Provides the strongest hard-endpoint evidence that switching from regular salt to a potassium-enriched substitute reduces stroke, cardiovascular events, and death over ~5 years. Used here on the inaction side as the peer-reviewed basis for the claim that continuing typical sodium intake carries a measurable cardiovascular cost in high-risk populations. The effect size in the SSaSS population (high prevalence of hypertension, prior stroke) does not translate directly to a general US adult population, but it establishes the direction unambiguously.

American Heart Association's standing dietary guidance page, updated through 2024. Provides the headline context numbers: the AHA daily targets (2,300 mg upper limit, 1,500 mg ideal) against the measured ~3,400 mg average US intake. Used here as the authoritative reference for the gap that motivates the inaction-side question at all — most US adults consume roughly 2x the AHA ideal. This is NOT a regret figure; it establishes that the inaction side (\"keep doing what you're doing\") is by public-health standards a position of measured over-consumption, not a neutral default. The 47.7% inaction-side regret-rate proxy comes from CDC NCHS Data Brief No. 511 (see above), not from this AHA page.

Mente et al. (Lancet 2016, PMID 27216139), pooled analysis of 133,118 individuals from 49 countries across four prospective studies including PURE. Reports a U-shaped/J-shaped association: sodium excretion below 3 g/day (~3,000 mg/day) carries significantly increased cardiovascular risk in both hypertensive and non-hypertensive adults relative to a 4-5 g/day reference range, in addition to the well-established high-intake risk (7 g/day or more) in hypertensives. This is NOT used to compute the inaction-side regret rate; it grounds the J-curve concern referenced in the caveats field and body text. The finding is contested on methodological grounds (24-hour sodium excretion was estimated from a single morning spot-urine sample via formula rather than measured directly) and has not displaced the AHA/WHO guidance recommending universal reduction toward 1,500-2,300 mg/day cited elsewhere in this entry.

Ressalvas
Nenhum dos lados mede arrependimento diretamente, e nenhuma pesquisa americana publicada pergunta "você se arrepende de reduzir sódio?" ou "você se arrepende de continuar a comer sal regular?" frontalmente. Os ~70% do lado da ação são o ponto médio das taxas de não-aderência em coortes de pacientes com insuficiência cardíaca, onde o caso médico para restrição é inequívoco e o aconselhamento profissional é intensivo. Chung et al. 2017 documenta essa aderência precária diretamente: pacientes não aderentes excretaram ~4.135 mg de sódio por dia contra ~3.086 mg entre os pacientes aderentes na medição objetiva de sódio urinário de 24 horas, e as taxas de aderência objetiva agrupadas na literatura giram em torno de 20-40%, o que implica que a maioria desiste. Entre adultos americanos saudáveis tentando redução voluntária de sódio sem pressão clínica, as taxas de lapso são quase certamente mais altas que 70%, não mais baixas. O número delimita a direção (a maioria das tentativas de redução de sódio falha em se sustentar) sem isolar um sinal de arrependimento. Os 47,7% do lado da inação são a prevalência de hipertensão em adultos americanos (CDC NCHS Data Brief 511) — uma medida de risco a jusante, não uma medida de arrependimento sobre hábitos de sal. A hipertensão tem múltiplas causas (genética, idade, peso, álcool, sódio, atividade física), e o sódio é uma das contribuintes. Muitos dos 47,7% nunca fizeram a conexão entre sua ingestão de sal e sua pressão arterial. A meta-análise Cochrane He, Li & MacGregor 2013 estabelece que a redução modesta de sal reduz a pressão arterial sistólica em 5,4 mm Hg em hipertensos e 2,4 mm Hg em normotensos — efeitos reais mas modestos. O ensaio SSaSS (Neal et al., NEJM 2021) mostra que a substituição por sal enriquecido com potássio reduz AVC, eventos cardiovasculares e morte em populações de alto risco.
