Gastrointestinal HealthApr 30, 2026
Orange-colored stool that catches you off guard is almost certainly tied to a recent meal, not a serious illness. The most well-documented cause is a specific reaction to certain deep-sea fish, and it has a name: keriorrhea. It looks alarming, but it resolves on its own and is not dangerous.
Stool color alone is rarely enough to diagnose anything. Clinical guidelines consistently emphasize other factors, like how long diarrhea lasts, whether there's blood, fever, or weight loss, over the shade in the bowl. Understanding that distinction is the most useful thing you can take away here.
NutritionApr 29, 2026
Protein bars can be a healthy, convenient protein source, but many commercial options are loaded with added sugars, unhealthy fats, and additives that undermine their supposed health benefits. A study of foods with protein claims in Spain found that products carrying protein labels were actually 13% more likely to be classified as "less healthy" by objective nutrient profiling standards than products without such claims.
The word "protein" on the package doesn't guarantee you're making a good choice. This article will walk you through exactly what to look for when you flip that bar over, with specific numbers and red flags backed by clinical research.
Bone HealthApr 28, 2026
Potassium bicarbonate consistently does one thing well in human studies: it reduces the amount of calcium your body dumps into urine. Multiple controlled trials confirm this. It also lowers markers of bone breakdown. On paper, that sounds like a clear win for your skeleton. But the research stops short of proving what most people actually care about: stronger bones and fewer fractures over the long haul.
The gap between "less calcium lost" and "bones that don't break" is wider than supplement marketing would have you believe. Here's what the evidence actually supports, where it falls apart, and what that means if you're considering potassium bicarbonate for bone health.
SupplementationApr 28, 2026
Isolated soluble fibers, the same types used in most fiber gummies (inulin, fructooligosaccharides, resistant starch), produce small but measurable improvements in body weight, blood sugar, and body composition. In adults with overweight or obesity, these fiber supplements reduced body weight by roughly 2.5 kg, along with improvements in BMI, body fat, fasting glucose, and insulin, over study periods ranging from 2 to 17 weeks.
That's a genuine effect, not a marketing fantasy. But it's also not the whole story. Most of the big, impressive health associations tied to fiber come from diets rich in whole plant foods, which bundle fiber with micronutrients and phytochemicals that an isolated supplement simply doesn't contain. Fiber gummies occupy a real but narrow lane.
CortisolApr 28, 2026
Almost any meal raises your cortisol. That is the blunt, slightly inconvenient finding from controlled feeding studies: carbohydrate, protein, and fat each triggered a cortisol increase of roughly 90 nmol/L, lasting one to three hours in both lean and obese men. The spike comes from two routes at once, direct adrenal secretion and the liver regenerating cortisol on its own.
So the question isn't really which magical "cortisol food" to avoid. It's which eating patterns push that normal, transient bump into something your body has to deal with repeatedly, and whether certain meals hit harder than others. The research points to three clear amplifiers.
Weight LossApr 28, 2026
Most of what you lose in your first week of 16:8 intermittent fasting is not fat. Clinical trials consistently show that meaningful, measurable weight loss from time-restricted eating builds over weeks, not days. After just seven days, the research points to changes under 1 kg, driven largely by shifts in water and glycogen rather than real fat reduction.
That doesn't mean the week was wasted. It means you're looking at the opening act, not the finale. Understanding the actual timeline helps you set expectations that won't collapse the moment progress feels slow.
ColonoscopyApr 28, 2026
Most people assume colonoscopy prep means days of dietary misery. The research tells a different story. For generally healthy, average-risk outpatients using a modern split-dose bowel prep, prospective data show no association between what you eat 2 to 3 days before the procedure and how clean your bowel ends up being.
That means the restrictive eating many people dread can usually be compressed into a single day, not two or three. Several randomized trials and meta-analyses back this up: extending a low-residue or low-fiber diet beyond one day before the colonoscopy does not improve prep quality. It just makes the whole process harder to follow.
Healthy EatingMar 15, 2026
The most effective vegetarian dinners aren't exotic or complicated. They're the meals you already make, with the meat swapped out. Research on plant-based versions of familiar dishes like lasagne, chilli, stir-fries, and curries finds they tend to have better nutrient profiles than their meat-based counterparts, while costing less and producing fewer emissions.
That last point is worth sitting with. You don't need a new cookbook or a pantry overhaul. You need lentils where the mince used to be.
