Bridging the cognitive health nutrient gap

·42 min·2 clips

Clinical trials show cognitive benefits at 900 mg or more of omega-3, while food-based guidelines recommend only 250 to 500 mg.

1. Food Matters Live Podcast presents a session recorded live at the Rotterdam event in September on nutrient gaps in cognitive health across life stages. 2. Anthony Zahra introduces the episode, and the speakers are Dr. Sophie Putnam, head of science at Holland and Barrett, and Dr. Aniko Korozy, Associate Professor at the University of Amsterdam's Faculty of Science. 3. The thread running through both talks is that nutrition early in life may protect the brain decades later, with Putnam stating that prevention starts "scarily early." 4. Putnam cites 50 million people living with dementia globally, a figure set to triple by 2050, and says one in four older adults in Europe report subjective cognitive impairment. 5. She reports that UK and EU intakes of omega-3 (EPA and DHA) and choline fall below recommendations across life stages, and that 76% of countries consume less EPA and DHA than the minimum global recommendation. 6. Putnam contrasts the 250 to 500 mg omega-3 guideline with trials showing benefit at 900 mg or more, and says none of the 10 best-selling brain health supplements on Amazon contain choline. 7. On emerging botanicals, she cites a 900 mg spearmint extract giving an 11% increase in sustained attention over 90 days, curcumin raising working memory by 5 to 10% at 12 weeks, and cocoa flavanols raising BDNF by about 15%. 8. Korozy covers the first 1,000 days of life, where adversity such as abuse, neglect, maternal depression or malnutrition (including the Dutch Famine Birth Cohort) raises the risk of mental and metabolic disease, and she links it to Alzheimer's disease risk. 9. In her mouse experiments, an omega-3-enriched diet fed through the mothers until postnatal day 42 rescued brain fatty acid levels and memory performance and removed the pro-inflammatory microglial state caused by early life stress. 10. Suited to nutrition scientists, supplement and food developers, and listeners following brain health research.
