Medical claims, wellness fads, and what the evidence actually supports.
Claim:
Under normal conditions, only a very small fraction of dietary amino acids in the small-intestinal lumen are diverted by other substances or are consumed by colonic bacteria before being absorbed, so amino-acid loss is very low.
HARDLY BS
Claim:
Most intestinal juice in the small intestine comes from the contents released when small-intestinal epithelial cells rupture and slough off, rather than from fluid actively secreted by intestinal glands.
TOTAL BS
Claim:
After proteases finish digesting food in the duodenum, they move with chyme into the mid and distal small intestine and begin digesting themselves and other enzymes into amino acids.
MOSTLY BS
Claim:
During acute stress, pulmonary blood flow increases mainly because cardiac output increases.
HARDLY BS
Claim:
Physiologic stress can increase intestinal permeability by disrupting tight junctions between enterocytes, which increases translocation of luminal antigens and bacteria.
HARDLY BS
Claim:
Villous blunting can reduce intestinal absorption of nutrients including glucose, amino acids, and fat-soluble vitamins.
NOT BS
Claim:
During an acute stress response, splanchnic vasoconstriction reduces gastrointestinal perfusion and prioritizes blood flow to the heart, lungs, and skeletal muscle.
HARDLY BS
Claim:
Reduced perfusion of the small-intestinal mucosa can impair enterocyte renewal and contribute to villous blunting (villous atrophy), reducing absorptive surface area.
NOT BS
Claim:
Consuming sugary drinks before midnight makes babies hyperactive and less likely to fall asleep at their usual bedtime.
TOTAL BS
Claim:
During emulsification in digestion, each microscopic fat droplet contains only lipids inside, bile salts form an outer coating with their hydrophobic ends facing inward and hydrophilic ends facing outward, and water surrounds the droplet…
HARDLY BS
Claim:
Pancreatic proteases such as trypsinogen and chymotrypsinogen are synthesized as inactive zymogens and are activated in the duodenum by an intestinal enzyme (enterokinase/enteropeptidase), which helps prevent autodigestion of the pancreas.
NOT BS
Claim:
Creatine supplementation improves brain fog in humans.
SOME BS
Claim:
Creatine supplementation reduces S-adenosylmethionine (SAMe) demand by decreasing endogenous creatine synthesis.
NOT BS
Claim:
COVID-19 vaccines did not help contain the COVID-19 pandemic.
TOTAL BS
Claim:
Cashiers are at increased risk of disease due to exposure to chemicals from handling thermal paper receipts.
SOME BS
Claim:
Dimethyl sulfoxide (DMSO) has anti-inflammatory effects in humans.
HARDLY BS
Claim:
Genetically modified (GMO) foods are dangerous to human health because DNA modification in the food can harm human health.
TOTAL BS
Claim:
Organic fruits are healthier than non-organic fruits.
SOME BS
Claim:
A meta-analysis published in 2023 found that taking 3,200 to 4,000 International Units (IU) of vitamin D daily is associated with a higher risk of hypercalcemia.
NOT BS
Claim:
Taking 5,000 IU of vitamin D daily does not cause side effects for most people.
HARDLY BS
No checks match that verdict.
