Dans quelle mesure le sucre et le sel ajoutés durant les deux premières années de vie augmentent-ils le risque de diabète de type 2 et d'hypertension à l'âge adulte ?
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.

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.

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.

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.

CDC NCHS Data Brief No. 511 (October 2024), based on NHANES August 2021 - August 2023 measurement data. 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.

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.

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.

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.

Aucun des deux côtés ne mesure le regret directement, et aucune enquête américaine publiée ne demande frontalement « regrettez-vous d'avoir adopté un régime pauvre en sodium ? » ou « regrettez-vous vos habitudes en sel ? ». Le taux d'environ 70 % côté action est un taux d'abandon à long terme issu de cohortes d'insuffisance cardiaque (Chung et al. 2017) où l'adhésion est prescrite, conseillée par des professionnels et médicalement urgente — Chung et al. 2017 documente directement cette mauvaise adhésion : les patients non adhérents excrétaient ~4 135 mg de sodium par jour contre ~3 086 mg chez les patients adhérents à la mesure objective de l'urine sur 24 heures. Nous utilisons ces ~70 % comme proxy côté action parce que les taux d'adhésion objective regroupés dans la littérature avoisinent 20-40 %, ce qui implique que la majorité abandonne ; chez les adultes américains en bonne santé tentant une réduction volontaire sans pression clinique, le taux d'abandon est presque certainement plus élevé, pas plus bas. Abandonner n'est pas regretter : certains ont abandonné parce que la nourriture est devenue inappétissante, certains à cause des repas sociaux ou familiaux, certains parce qu'ils ont conclu que le bénéfice ne valait pas le sacrifice. Le 47,7 % côté inaction est la prévalence d'hypertension chez les adultes américains de 18 ans et plus du CDC NCHS Data Brief N° 511 (oct. 2024), basée sur les données de mesure NHANES août 2021 - août 2023 — un état clinique en aval que l'apport en sodium cause en partie, pas une mesure de regret sur les habitudes en sel. Beaucoup de ces 47,7 % n'ont jamais fait le lien entre leur apport en sel et leur tension artérielle, et beaucoup des 52,3 % sans hypertension pourraient encore regretter leurs habitudes en sel pour d'autres raisons (goût, antécédents familiaux, conseil médical). La réanalyse PURE du Lancet de Mente 2016 a rapporté une association en U entre l'excrétion urinaire de sodium et les événements cardiovasculaires, avec un risque excessif apparent en dessous d'environ 3 000 mg/jour — ce résultat est contesté pour des raisons méthodologiques (urine ponctuelle unique avec la formule Kawasaki) et n'est pas actuellement reflété dans les directives majeures (AHA, OMS), mais c'est la base publiée la plus propre pour la préoccupation de courbe en J selon laquelle les régimes pauvres en sodium pourraient ne pas bénéficier aux adultes normotendus à l'apport le plus bas. L'essai SSaSS du NEJM 2021 en Chine rurale fournit la preuve la plus solide sur critères durs (AVC, événements cardiovasculaires, mortalité toutes causes tous réduits d'environ 12-14 %) pour la réduction de sodium, mais la population (adultes chinois plus âgés avec hypertension ou AVC antérieur, apport de référence d'environ 5 000 mg/jour) ne se traduit pas proprement à la population générale d'adultes américains. Les deux chiffres encadrent une réponse directionnelle (la plupart des tentatives de réduction du sodium échouent à se maintenir ; la plupart des adultes américains consomment bien au-dessus de la cible AHA avec des conséquences cardiovasculaires en aval) sans produire de comparaison numérique propre du regret.
