A roundup of today's exercise, healthy-living, and nutrition developments for October 14, 2026, with summaries, links, and commentary.
I. Nutrition and Diet
1. Chemical Senses: In 6,690 adults in South Tyrol, healthier plant-rich diet scores tracked with better odor identification (Nutrition)
Summary:
Essi Hantikainen, Roberto Melotti, Martin Gögele, Peter Pramstaller, Christian Fuchsberger, and Johannes Frasnelli published a cross-sectional analysis online in Chemical Senses on October 6 (doi: 10.1093/chemse/bjag028). News-Medical reported it on October 14. The analytic sample from the CHRIS population study in South Tyrol, Italy, was 6,690 adults, mean age 44.5 years, 54% women. Diet came from the GA2LEN semiquantitative food-frequency questionnaire, scored as the Alternate Healthy Eating Index 2010 (AHEI), a Mediterranean diet index (MED), and overall, healthful, and unhealthful plant-based diet indices (PDI, hPDI, uPDI). Smell was the 16-item Sniffin' Sticks identification test, with hyposmia defined as 12 or fewer correct. Per 1-standard-deviation higher score, the odds of a better olfactory category were 1.09 for AHEI, 1.06 for MED, 1.05 for PDI, and 1.07 for hPDI; uPDI ran in the opposite direction. The paper describes the continuous associations of AHEI, MED, and PDI with hyposmia as very similar, about an odds ratio of 0.87 (95% CI 0.81 to 0.94); hPDI was 0.92 (0.85 to 0.99) and uPDI was 1.12 (1.04 to 1.21). Highest versus lowest quartile, the hyposmia odds ratio was 0.65 (0.56 to 0.86) for PDI and 1.37 (1.11 to 1.69) for uPDI. Reported fruit, vegetable, tea, and coffee intake tracked with better odor identification. After further adjustment for Parkinsonism screening and the Mini-Mental State Examination, the PDI and MED associations with olfactory function, and the hPDI association with hyposmia, were no longer significant. The authors say the alcohol-consumer association is not evidence that drinking improves smell, and they cite guidance that no level of alcohol is safe.

Commentary:
If odor identification is slipping, put fruit, vegetables, tea, and coffee into this week's meals as a pattern that points the same way; a questionnaire plus a smell test cannot show that diet repairs smell, because smell loss can also change what people choose to eat.
2. BMC Nutrition: Among 120 healthy Syrian adolescents, systolic pressure was 17 mmHg lower in week 3 of Ramadan than in week 1, with no change in weight (Nutrition)
Summary:
Samah Jalal Jabr and colleagues at the Faculty of Medicine, Syrian Private University, published an open-access repeated-measures observational study in BMC Nutrition on October 14. The sample was 120 healthy adolescents (65 male, 55 female; mean age 18) at a specialized secondary school in Daraa, Syria, during Ramadan 1447 AH in 2026. Measurements were taken in week 1 and week 3. Systolic pressure moved from 129 mmHg to 113 mmHg, mean difference −17 mmHg (95% CI −20 to −14; Cohen's d = 1.17). Diastolic pressure moved from 81 mmHg to 73 mmHg, mean difference −8 mmHg (−11 to −6; d = 0.65). Resting heart rate moved from 90 to 95 beats per minute, mean difference +5 (3 to 8; d = 0.45). Rate-pressure product fell and shock index rose. Body mass, BMI, and overall fatigue-related symptoms did not change significantly. Blood-pressure reductions were similar in males and females; the heart-rate rise was larger in males. Participants who skipped suhoor had larger drops in systolic and diastolic pressure and a larger rise in heart rate. The study did not measure diet composition, fluid intake, or laboratory markers, and it had no non-fasting control. Ethics approval was SPU-MED-2025-IRB-07. The authors report no funding and no competing interests.

Commentary:
Adolescents who are fasting can still eat suhoor: those who skipped it had larger blood-pressure drops and higher heart rates, and body weight did not fall; this is a within-Ramadan comparison, so it is not a protocol for lowering blood pressure by fasting.
II. Exercise and Training Science
3. Scientific Reports: In 16 elite female boxers, punching sprints at 80% arterial occlusion pressure raised the growth-hormone change and reduced punch output (Training)
Summary:
Shenguang Li, Dexin Wang, Pedro G. Morouço, Chao Chen, and Zixiang Zhou published an open-access randomized crossover trial in Scientific Reports on October 14. Sixteen national-level elite female boxers (age 22.51 ± 3.27 years, height 165.11 ± 4.64 cm, weight 54.76 ± 8.01 kg) completed four conditions separated by 7 days: no blood-flow restriction, and 45%, 60%, and 80% of arterial occlusion pressure. Mean occlusion pressure was 322 ± 41 mmHg. Each session was 3 sets of 6 repetitions of 10-second all-out straight punches, with 20 seconds between repetitions and 1 minute between sets; cuffs were deflated between sets. Restriction, especially at 80%, produced higher muscle activation and larger changes in muscle oxygen saturation. Growth hormone rose after exercise in every condition, and only the 80% condition had a significantly larger growth-hormone change than no restriction. Nitric oxide rose versus pre-exercise at 60% and 80%. Insulin-like growth factor-1 rose versus pre-exercise only at 80%. Leg soreness scores were higher under restriction in set 3, and at 24 hours the 80% condition remained higher than no restriction. Punch count and cumulative punch force fell as pressure rose. The authors say soreness and the performance drop generally recovered within 48 hours. This is one acute session, not a multi-week adaptation trial. Ethics approval was Shanghai University of Sport 102772023RT128.

Commentary:
A commercial gym session should not copy 80% arterial occlusion on all-out punches: these 16 elite women did it once, threw fewer punches, and the highest pressure still hurt at 24 hours, with recovery described as generally within 48 hours, without evidence of later size or fight-performance gains.
III. Sleep and Mental Health
4. PLOS Mental Health: High-arousal index rose after the threat was removed in 24 adults with insomnia and fell slightly in 24 good sleepers (Sleep)
Summary:
Tianyu Hwang, Saman Khazaei, and Rose T. Faghih at the NYU Tandon School of Engineering, with Edward F. Pace-Schott and Ryan Bottary at Massachusetts General Hospital and Harvard Medical School, published in PLOS Mental Health on October 14 (doi: 10.1371/journal.pmen.0000720). They reanalyzed an existing fear-conditioning dataset: 24 people with insomnia disorder and 24 good sleepers, 18 women and 6 men in each group. Original recruitment ran from February 10, 2014, to February 4, 2017. A visual cue was paired with a mild shock, then presented without the shock so participants could learn that it was safe, with recall the next day. Skin conductance was split into autonomic spikes and the continuous background. A spikes-only model did not separate the groups. Once the background signal was included, the average high-arousal index rose from conditioning to extinction in the insomnia group and fell slightly in the good sleepers. Lower average arousal during conditioning and higher arousal at next-day recall pointed the same way and did not reach significance. The authors read this as a safety memory that was not fully acquired on day one or retained to day two. Funding included NIH R35GM151353 and NSF 2226123, with no funder role in design or publication. This is a computational reanalysis of skin conductance, not a treatment trial.

Commentary:
When exposure practice or the lesson that a cue is safe will not stick, treat the insomnia as sustained arousal that needs its own plan; a 24-versus-24 skin-conductance reanalysis does not specify which sleep treatment to use.
IV. Public Health and Disease Prevention
5. BMC Public Health: Among 84,797 Italians aged 0–29, having a foreign-citizen parent corresponded to a sedentary odds ratio of 1.73 and an overweight-or-obesity odds ratio of 1.15 (Public health)
Summary:
Leonardo Maria Siena, Antonio Sciurti, Anteo Di Napoli, Christian Napoli, Corrado De Vito, Valentina Baccolini, and Alessio Petrelli, at Sapienza University of Rome and Italy's National Institute for Health, Migration and Poverty, published an open-access analysis in BMC Public Health on October 14. The source was ISTAT's Daily Life Aspects surveys for 2015–2022. The sample was 84,797 people aged 0–29: 77,097 with two Italian-citizen parents and 7,700 with at least one foreign-citizen parent. Multivariable logistic regression with household-clustered standard errors found an adjusted odds ratio of 1.05 (95% CI 0.93 to 1.18) for self-rated health that was not good, with no significant group difference. Young people with at least one foreign-citizen parent had adjusted odds ratios of 1.15 (1.07 to 1.24) for overweight or obesity and 1.73 (1.59 to 1.87) for a sedentary lifestyle. At-risk alcohol use was 0.66 (0.58 to 0.75) and smoking was 0.85 (0.76 to 0.95). Fruit and vegetable intake showed no clear difference. Models adjusted for demographic, socioeconomic, household, and contextual factors. These are repeated cross-sectional surveys, not a cohort of the same children followed into adulthood. The authors report no funding.

Commentary:
For children and young adults with a foreign-citizen parent, the practical targets in these surveys are long sitting time and rising weight; alcohol and smoking were less common in that group, and the surveys do not establish a genetic difference.
6. Science Advances: After pregnant mice received a K1/K2 capsule vaccine, more than 80% of two-week-old pups survived Klebsiella challenge (Public health)
Summary:
Washington University School of Medicine in St. Louis announced on October 14 that a mouse study by Paeton L. Wantuch, David A. Rosen, and colleagues appeared the same day in Science Advances (doi: 10.1126/sciadv.aeh8222). Klebsiella pneumoniae is a major cause of infant bloodstream infection in low- and middle-income countries, resistance is increasing, and no preventive vaccine is available. Female mice were immunized at mating and again once or twice during pregnancy. The vaccine, developed by the St. Louis company Omniose, targets the K1 and K2 capsule types. Rosen had previously reported protection in adult mice. Two weeks after birth, pups received a lethal dose of K1 or K2. Among pups of unvaccinated mothers, survival was 0% for K1 and under 35% for K2. Among pups of vaccinated mothers, survival exceeded 80% for either type. Two maternal doses and three maternal doses did not differ in pup survival. The release attributes protection to maternal immunity. This is a mouse challenge experiment, with no human pregnancy data.

Commentary:
Prenatal vaccine schedules stay as they are after this mouse result; it shows maternal antibody can protect newborn mice from Klebsiella bloodstream infection, and human safety and efficacy trials are still required before any dose exists for people.
7. International Archives of Occupational and Environmental Health: In 388 adults aged 60 and older in Antalya, a higher fatigue index tracked with a higher musculoskeletal burden (Public health)
Summary:
Barış Kılıç and colleagues published a cross-sectional indirect-association analysis on October 14 in the International Archives of Occupational and Environmental Health. In 2021 they surveyed 400 community-dwelling adults aged 60 and older in Antalya, Türkiye. Activity was the Physical Activity Scale for the Elderly (PASE), musculoskeletal discomfort the Cornell questionnaire (CMDQ), and fatigue the Multidimensional Assessment of Fatigue, summarized as a Global Fatigue Index (GFI). The regression sample was 388 people, and 54.1% had a CMDQ score of zero. Higher GFI corresponded to greater CMDQ burden (B = 3.114, SE = 0.566, p < 0.001), and the direction stayed positive after transformation, winsorization, and influential-point checks. In the primary model, total PASE was not associated with CMDQ (B = −0.053, p = 0.245); after dropping influential observations the coefficient was −0.044 (p = 0.027). Bootstrap 95% confidence intervals from 5,000 resamples for indirect estimates through GFI excluded zero: prior infection 15.55 (6.02 to 26.89), female sex 8.66 (1.49 to 17.55), and ordinal education −4.61 (−9.68 to −0.65). The authors state that the indirect estimates are cross-sectional and do not establish temporal order or causal mediation.

Commentary:
When adults over 60 have widespread aches together with daytime fatigue, address fatigue and recovery before expecting a higher activity-scale score to explain the pain; the activity association was unstable in the main model, and the questionnaires were collected in 2021.
V. Evidence and Clarification
8. Sleep and Vigilance: Seven days of 20 g creatine a day did not improve cognition or frontal oxygenation after one 3-hour night in 8 healthy adults (Evidence check)
Summary:
David M. Shaw, Juliette Janvresse, Margo van den Berg, Peter Michael Bloomfield, and Nicholas Gant, including investigators at Massey University, published an open-access randomized, double-blind, placebo-controlled crossover pilot in Sleep and Vigilance on October 14 (retrospectively registered as ACTRN12626000301369). Eight healthy adults (4 women, 4 men; ages 18–50, BMI under 30) started after at least two nights of sufficient sleep, then took 20 g per day of creatine monohydrate or a tapioca placebo, split into four doses, for 7 days, and restricted one night in bed to 3 hours (about 03:30–06:30). Arms were separated by a washout of at least 5 weeks. Sleep restriction slowed mean reciprocal response time and the mean fastest 10% of reaction times, and it increased fatigue, workload, and sleepiness while reducing vigor (all p < 0.05). Lapses, the slowest 10% of reaction times, running-memory continuous performance, logical relations, Stroop interference, and task-evoked cerebral hemoglobin oxygenation did not change significantly (all p > 0.05). Creatine had no significant effect on any cognitive or physiological variable (all p > 0.05). Equivalence held for the fastest 10% reaction time, the slowest 10% reaction time, and running-memory throughput; for the other variables a meaningful effect could not be excluded. Recruitment ran from March 1 to September 30, 2022. The authors say the study was underpowered to confirm or rule out smaller effects.
Links:
Commentary:
After a night of about 3 hours in bed, the next step is sleep, not a prior week of 20 g creatine a day as a cognitive rescue; this eight-person pilot saw no benefit and is still too small to declare creatine useless for every kind of sleep loss.
Today's Summary
- Diet: In 6,690 adults in South Tyrol, fruit, vegetables, and healthier plant-rich scores tracked with better odor identification; in 120 Syrian adolescents, week 3 of Ramadan brought lower blood pressure and a higher heart rate, with larger shifts when suhoor was skipped and no change in weight.
- Training: Sixteen elite female boxers at 80% arterial occlusion pressure showed larger muscle-activation and growth-hormone changes, fewer punches, and soreness that could last 24 hours.
- Sleep: The high-arousal index rose after the threat was removed in 24 adults with insomnia; in an eight-person pilot, 20 g of creatine a day for 7 days did not improve cognition or frontal oxygenation after one 3-hour night.
- Public health: Young people in Italy with a foreign-citizen parent had higher odds of sedentary behavior and overweight; a K1/K2 vaccine in pregnant mice left more than 80% of two-week-old pups alive after Klebsiella challenge, still in mice.
Daily Framing:
Today in the sports, health, and nutrition cycle was a day of boundaries: plant-rich eating only tracked with smell, boxing blood-flow restriction was one acute stress, a creatine load did not replace a 3-hour night, and the maternal Klebsiella vaccine remains a mouse experiment.
