Nutrients and how the body handles them — fiber, resistant starch, beta-glucan, glucose response, and what to make of dietary fats and proteins.
Sweeteners
Sweeteners span everything from table sugar and high-fructose corn syrup to artificial sweeteners (aspartame, sucralose, saccharin) and natural or sugar-a…

18 claimsPesticide residues on food are one of the most-searched health worries and one of the most consistently mis-scoped. The honest split: the genuine harms in…

6 claimsThe world's most-used herbicide, and an unusual case of open regulatory disagreement: IARC called it probably carcinogenic in 2015 while EPA and EFSA conc…

5 claimsPrebiotic fibers (inulin, oligofructose). Lower fasting glucose in type-2 diabetes (well-supported); raise the appetite hormone GLP-1 and reduce body weig…

4 claimsPost-meal rises in blood sugar. In people with diabetes they clearly matter; the contested part is the popular claim that normal-range spikes meaningfully…
Explore Postprandial glucose spikes →Resistant starch
3 claimsA starch that resists digestion and ferments in the colon. Improves insulin sensitivity and blunts post-meal glucose; does NOT meaningfully reduce body we…
Explore Resistant starch →A1 beta-casein
2 claimsThe A1 variant of milk's beta-casein (releases BCM-7). Reliably worsens GI symptoms versus A2 milk in sensitive people; the claimed effect on cognition is…
Explore A1 beta-casein →Beta-glucan
2 claimsSoluble fiber from oats and barley. Well-supported for lowering LDL cholesterol and reducing the post-meal glucose spike.
Explore Beta-glucan →Dietary fiber
2 claimsBroad viscous/fermentable fibers. Help mitigate the GI side effects of GLP-1 drugs and may reduce GLP-1 resistance via gut-barrier support (an emerging, s…
Explore Dietary fiber →Psyllium
2 claimsA viscous soluble fiber (husk). Well-supported for both lowering LDL cholesterol and blunting the post-meal glucose rise.
Explore Psyllium →Saturated fat
2 claimsSaturated fat's clearest, best-established effect is raising LDL cholesterol. Its role in heart disease is more nuanced than either camp claims: swapping…

Is dietary fibre useless or unnecessary for health?
No — fibre is among the best-supported protective nutrients, consistently linked to lower all-cause, cardiovascular and cancer mortality with a plausible SCFA mechanism.
dietary fibre provides no health benefit
Do humans need dietary fibre for healthy bowels?
Mostly yes for population gut health, but fibre is not universally required and can worsen some idiopathic constipation — Baker overgeneralizes a real exception.
dietary fibre is-necessary-for bowel regularity and gut health
Is a fiber-free all-meat carnivore diet nutritionally safe, or is fiber genuinely necessary?
Fiber isn't a classical essential nutrient and some people tolerate low intake, but large dose-response meta-analyses tie higher fiber to lower all-cause, cardiovascular and cancer mortality and better glycemic control — and cutting all plants also drops vitamin C — so 'fiber is not needed' is contradicted by the weight of evidence.
