A Mouse Study Says Sweeteners Left Marks Two Generations On, and It Is Being Read Far Too Confidently

47 mice drank water, sucralose or stevia. Their children and grandchildren, who drank only water, showed some of the same changes to gut bacteria and gene activity. That is genuinely interesting and it is not a finding about people.

They Changed the Light and the Algae Started Making the Vitamin B12 a Human Can Actually Use

Ordinary spirulina is full of a B12 lookalike the body cannot use, which is why it has never been the answer for anyone avoiding animal food. Adjusting the light it grows under produced 1.64 micrograms of the active form per 100 grams.

Every One of 212 Plant Based Products Tested in Britain Contained a Fungal Toxin

A survey published in Food Control screened UK burgers, vegan sausages and oat, almond and soy drinks for 19 mycotoxins. All 212 carried at least one. Every measured level sat below the European guideline, which is the part people keep skipping.

Wine Drinkers Died Less Often in a 340,000 Person Study, and the Most Likely Explanation Is Dinner

An analysis of 340,924 UK Biobank adults found moderate wine drinkers had a 21 per cent lower risk of cardiovascular death, while beer, cider and spirits went the other way. The researchers' own leading explanation is not the wine.

The Mice Kept Eating Less and Put the Weight Back On Anyway. That Is the Interesting Part.

A Yale study found semaglutide switches the brain's hunger neurons on rather than off, and that those neurons are required for fat loss to last. Remove them and the mice ate just as little and regained the weight within fifteen days.

Psyllium Husk Is the Dullest Thing in the Supplement Aisle and Almost the Only One That Works

It has an authorised FDA health claim, which almost no supplement does, and meta-analyses behind it for cholesterol, blood glucose and constipation. One gel-forming property explains all three, and so does the way it goes wrong.

Sugar-Free Does Not Mean Carbohydrate-Free, and the Biscuit Knows That Even If You Do Not

A product can be free of sugar, full of refined flour, sweetened with something that still raises glucose, and carry more fat and calories than the version it replaced. Regulators in Europe eventually stopped allowing a diabetic food category altogether.

Eating the Same Meal in a Different Order Cut Post-Meal Glucose by More Than a Third

Identical food, identical calories, identical macronutrients. The only variable was what went in the mouth first, and glucose at sixty minutes fell by 36.7 per cent. It is the cheapest intervention in diabetes nutrition.

A Protein Bar Is Ultra-Processed. New Trial Data Says That May Not Be the Point

Protein-enriched processed foods produced higher satiety hormones and lower calorie intake than normal-protein versions of the same products. It complicates a classification a lot of advice now rests on.

Nobody Counts What They Drink, Which Is Where Most of the Sugar Is

Liquid sugar arrives faster than any solid food, does almost nothing to make you feel full, and is invisible in the mental accounting people do about their diet. Four cups of sweet karak is a dessert nobody counted.

A Diet Trial Was Stopped Early Because the Control Group Was Doing Measurably Worse

PREDIMED tested a Mediterranean diet with added olive oil or nuts against low-fat advice. Diabetes incidence was 6.9 per cent with olive oil against 8.8 per cent on the low-fat arm, and the follow-up trial did considerably better.

Watermelon Has a High Glycaemic Index and It Does Not Matter, Which Tells You What Is Wrong With the Number

Glycaemic index measures the quality of a carbohydrate in a standardised portion nobody eats. Glycaemic load multiplies it by the amount actually on the plate, and the two frequently disagree.

People With Diabetes Are Still Being Told to Avoid Fruit, and the Evidence Points the Other Way

Fruit contains sugar, so the advice writes itself and it is wrong. The relevant distinction is not sweet versus not sweet. It is whether the sugar is still inside a structure that has to be dismantled before it can be absorbed.

Somebody Actually Measured What Five Varieties of Dates Do to Blood Sugar, in the UAE, in People With Diabetes

Dates are sweet, so the assumption is that people with diabetes should avoid them. A study of Fara'd, Lulu, Bo ma'an, Dabbas and Khalas found low glycaemic indices and no significant glucose excursions in the diabetic group.

The WHO Advised Against Sweeteners, and Then Made One Exception That Nobody Reported

The 2023 guideline told people not to use non-sugar sweeteners for weight control. It explicitly does not apply to people who already have diabetes, which is precisely the group that read the headline and threw them out.

Brown Bread Is Usually White Bread With Colouring, and the Label Is Allowed to Say So Quietly

Wholemeal, wholegrain, multigrain, brown, granary and wheat all sound like the same promise. Only one of them reliably means the whole grain is in there, and the difference shows up in your glucose two hours later.

You Do Not Have to Give Up Rice. You Do Have to Change Which One, How Much, and What Is On It

Telling a household built around rice to stop eating rice is advice that gets nodded at and ignored. Four changes to the same plate do more for post-meal glucose than an instruction nobody will follow.

Histamine Intolerance: Popular Online, Thin on Evidence
