Eating from 30+ plant foods daily shifted gut microbiome composition more than a standalone probiotic — and reduced GI symptoms across the board in a 399-person RCT. (Sometimes the research just confirms what good practitioners already know.) A new meta-analysis adds Chlorella to the short list of supplements showing movement on LDL, insulin resistance, and body fat simultaneously. Plus: the skin-longevity science is more interesting than it sounds, and a clinical webinar on pediatric gut-brain overlap you won’t want to miss.

Evidence Spotlight
|
Plant Diversity vs. Single Probiotic
A 6-week RCT (n=399 adults with low fiber intake) compared a whole-food plant blend containing 30+ ingredients against both a control diet and a Lactobacillus rhamnosus probiotic. The plant blend shifted 57 gut microbiome species — compared to 14 for the control and just 4 for the probiotic — while also reducing GI symptoms and increasing energy. Adherence exceeded 98% with no serious adverse events.
Takeaway: For nutrition practitioners, this head-to-head comparison is notable: broad plant food diversity appears to be a stronger lever for microbiome modulation than single-strain probiotic supplementation at this dose, while also delivering real-world GI symptom benefits. It reinforces the clinical case for prioritizing variety of whole plant foods alongside — or sometimes ahead of — probiotic recommendations.

Chlorella’s Multi-Marker Metabolic Signal
A systematic review and meta-analysis of 24 studies found Chlorella supplementation was associated with improvements in LDL cholesterol, insulin resistance, and body fat percentage — alongside reductions in inflammation markers. However, evidence quality was rated low to very low, meaning the underlying trials had significant methodological limitations. These findings should be interpreted as directional signals rather than established effects.
Takeaway: Chlorella is worth understanding as a conversation piece for practitioners whose clients ask about algae-based supplements — the breadth of markers showing movement is clinically interesting. However, the very low evidence quality rating means the underlying trials were so methodologically flawed that we can’t confidently say these effects are real. This is hypothesis-generating territory, not a basis for confident clinical recommendations.

NO-Boosting Food, Unexpected BP Signal
A small Phase IIb crossover trial (n=21 adults with metabolic syndrome) tested a trigonelline-rich Sakurajima radish powder against a standard radish powder and usual diet, measuring flow-mediated dilation (FMD) as the primary outcome. Despite raising nitric oxide production, the intervention paradoxically increased oxidative stress and systolic blood pressure by roughly 9–10 mmHg — and did not improve blood vessel function. The small sample and crossover design mean these findings need replication, but the direction of the adverse signal is clinically meaningful.
Takeaway: This trial offers a clinically meaningful caution: in the pro-oxidant environment of metabolic syndrome, a nitric oxide–boosting functional food produced the opposite of the expected hemodynamic benefit. For practitioners recommending NO-pathway interventions to clients with metabolic syndrome, this is an early signal that the underlying oxidative environment may blunt — or reverse — expected effects.

By The Numbers
57 vs. 4 species
changed relative abundance after 6 weeks on a 30+ plant food blend — compared to just 4 species on a standalone probiotic.
This 399-person RCT compared a diverse whole-food plant blend against both an isoenergetic control and a Lactobacillus rhamnosus probiotic. The plant blend shifted 57 gut microbiome species versus 14 for the control and just 4 for the probiotic. Participants also reported less indigestion, constipation, heartburn, and flatulence — with no serious adverse events across the trial.

CLINICAL PEARL
When boosting nitric oxide backfired in metabolic syndrome
A trigonelline-rich radish successfully increased nitric oxide production in adults with metabolic syndrome — but paradoxically raised blood pressure by 9-10 mmHg instead of lowering it. The finding suggests that in high oxidative-stress environments, NO-boosting interventions may produce the opposite of the intended hemodynamic effect. It’s an early signal that underlying metabolic context can flip expected outcomes.

The Skin Longevity Breakthrough | Carolina Reis Oliveira
New Frontiers in Functional Medicine® with Dr. Kara Fitzgerald • July 7, 2026
Dr. Kara Fitzgerald speaks with Carolina Reis Oliveira, PhD — CEO and co-founder of OneSkin — about the science of cellular senescence in skin and its broader connections to systemic inflammation and aging. The conversation covers how a topical peptide (OS-01) emerged from screening over 900 candidates, skin-specific biological age testing, and how factors like rapid weight loss and GLP-1 use affect skin quality and barrier function. Functional medicine practitioners curious about the skin-longevity intersection — or fielding client questions about GLP-1-related body composition changes — will find the mechanistic framing here genuinely useful.

Gut, Brain, and Hormones: The Menopause Connection with Dr. Amy Shah
unPAUSED with Dr. Mary Claire Haver • June 30, 2026
Dr. Mary Claire Haver and Dr. Amy Shah dig into how declining estrogen during menopause affects the estrobolome — the subset of gut bacteria involved in estrogen metabolism — and how that cascade can contribute to symptoms including brain fog, mood changes, and weight gain. Dr. Shah also introduces a practical nutrition framework (30 grams of protein at first meal, 30 grams of fiber daily, and 3 servings of fermented foods) alongside discussion of cortisol dysregulation, insulin resistance, and circadian fasting. Practitioners working with perimenopausal and menopausal clients will find this episode clinically rich, especially for linking gut health conversations to hormonal symptom patterns. Listen →

US BioTek Adds New Markers to Organic Acids Profile
US BioTek published new practitioner guidance clarifying how arabinose and arabinitol — two markers on organic acids profiles — work together to improve the specificity of fungal and microbial activity assessment. Arabinose alone flags possible fungal activity or carbohydrate fermentation, while arabinitol adds the resolution needed to distinguish true fungal overgrowth from other causes. The combined pattern is more clinically informative than either marker in isolation. Read more →
