what it claims

You should monitor physical signs of dehydration (such as dark urine, fatigue, brain fog, or headaches) and use electrolyte-enriched hydration solutions to address them more easily.

Identifying urine color and thirst as direct indicators of hydration status is solidly validated by research, notably in the recommendations of the European Society for Clinical Nutrition and Metabolism (ESPEN, expert consensus). Regarding impacts on mental well-being (fatigue, decreased focus, irritability), a meta-analysis published by Zhang et al. (2019) confirms that even mild dehydration (1 to 2% water loss) impairs alertness and attention capacity. As for headaches, a randomized controlled trial (RCT) by Spigt et al. (2012) shows that increasing water intake helps significantly to reduce their intensity. However, presenting nausea as a daily sign is an exaggeration, as this symptom generally appears only in cases of very pronounced dehydration or extreme exertion. Finally, while electrolyte powders optimize water assimilation, plain water remains largely sufficient for basic hydration during a sedentary day.

Frozen vegetables are just as nutritious, if not more so, than fresh vegetables because they are frozen immediately after harvest, which preserves their nutrients, unlike fresh produce which loses its nutritional value during transport and storage.

Frozen vegetables are just as nutritious, and sometimes even more so, than fresh vegetables, because immediate freezing after harvest preserves their vitamins and minerals, unlike fresh produce which naturally loses nutrients during transport and storage in our refrigerators.

Others on this

The buzz from a Monster Energy comes almost entirely from its caffeine (and the sugar riding along with it) — the taurine and the B-vitamin megadoses on the can don't add a proven benefit beyond that.

Extreme, prolonged sun deprivation — like months aboard a nuclear submarine — is exactly the scenario where routine vitamin D supplementation makes real sense: several studies on submarine crews (Royal Navy, US Navy) show levels drop markedly within weeks without it.

For women in their 20s: four basics are enough — omega-3, vitamin D3, magnesium glycinate, and a quality probiotic — rather than 15 supplements.

Other advice in the Register that leans on the same research.

Drinking still water throughout the day can lead to dehydration; it is necessary to add a pinch of salt to your water for optimal hydration.

mixedDr. Stacy T. Sims

Systematically adding salt to drinking water is unnecessary for the majority of people, as hydration with plain water is sufficient for daily life.

Do not wait until you are thirsty to hydrate during exercise; it is recommended to drink regularly, ideally between 300 and 500 ml per hour, starting from the beginning of the session.
