The Scoop on Bioactive Peptides
With the annual national conference right around the corner, many dietitians are gearing up for a trip to this year’s Minneapolis-based event. Presenters will cover trending topics in integrating obesity medications and nutrition therapy, health equity in nutrition care, advances in approaches to weight management, and other updates in targeted MNT for select populations and health conditions of interest. Come say hello to us at Today’s Dietitian (TD), booth location #918. I look forward to seeing you there!
In this month’s E-News Exclusive, TD reviews the latest research on bioactive peptides. Bioactive peptides are specific small amino acid fragments capable of promoting physiological changes in the body.1 Bioactive peptides can be found alone, though many of them are tucked away in the intact structure of protein molecules, and their unique amino acid composition, sequence, and molecular weight allow them to exert specialized effects on target tissues.1 Due to their potential health-related applications, including antimicrobial, antihypertensive, antioxidant, blood lipid-lowering, antidiabetic, and antiaging effects, new research seeks to identify progressive therapeutic applications.1 |

Bioactive Peptides and Nutrition Therapy
By Heather Davis, MS, RDN, LDN
Beyond a classic appreciation of its nutritive value, protein exerts specialized physiochemical action that expands its health impact. Bioactive peptides (BPs) are specific protein fragments, often three to 20 amino acids long, with unique health effects.1
Since many bodily functions are guided by amino acid interactions between peptide fragments or small protein chains, BPs offer potential for targeted therapeutic applications, including use in nutrition therapy.2
All About BPs
BPs are classified into two main groups: endogenous and exogenous. Endogenous forms are produced in certain cells, such as neural and immune cells, or in the pituitary and adrenal glands; exogenous forms are found in foods, dietary supplements, and pharmaceutical drugs.1 It’s also possible to synthesize BPs in a lab with the help of chemical reagents.
Some of the earliest syntheses of BPs took place in 1953 to produce prescription insulin. However, some of the synthetic processes, such as ones involving dimethylformamide and dichloromethane, have been criticized for their environmental harm and the fact that these compounds are difficult to remove from nature.1

Healthful Diet With Less Sugar Is Linked to Younger Biological Age
Researchers at the University of California, San Francisco (UCSF) have found a link between following a diet that’s rich in vitamins and minerals, especially one without much added sugar, and having a younger biological age at the cellular level.
They looked at how three different measures of healthful eating affected an “epigenetic clock”—a biochemical test that can approximate both health and lifespan—and found that the better people ate, the younger their cells looked. Even when people ate healthful diets, each gram of added sugar they consumed was associated with an increase in their epigenetic age.

“The diets we examined align with existing recommendations for preventing disease and promoting health, and they highlight the potency of antioxidant and anti-inflammatory nutrients in particular,” explains Dorothy Chiu, PhD, a postdoctoral scholar at the UCSF Osher Center for Integrative Health and first author of the study. “From a lifestyle medicine standpoint, it’s empowering to see how heeding these recommendations may promote a younger cellular age relative to chronological age.”

Eating These Foods Lowers Dementia Risk, Study Says
A new study suggests that swapping ultraprocessed foods like pizza and ice cream for anti-inflammatory foods like fruit and whole grains could lower risk of dementia by 31%, reports CNN.
FDA Moves to Further Reduce Salt Levels in Food
The FDA has announced its proceeding with Phase 2 of its to reduce salt in foods, reports U.S. News. The new voluntary targets are in an effort to limit individual sodium intake to 2,750 mg per day and coincide with the USDA’s efforts to limit sodium in school lunches. |
