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…

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 required for bowel regularity and gut health
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 does not improve health outcomes
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.
dietary fibre is a non-essential so an all-meat diet is nutritionally safe
