In each edition, I’ll share the most interesting and actionable findings from the latest health studies so you can stay informed (without sifting through dense medical journals).
Here’s what I found this month:

Ashwagandha Helped Stressed Adults Lose Weight |
|
Stress and stubborn weight tend to travel together. Cortisol drives cravings, and cravings drive eating, so the two can reinforce each other over time. A randomized, placebo-controlled trial (gold-standard study design) put that link to the test in 100 stressed adults carrying excess weight. Half took ashwagandha root extract (300 mg twice daily), half took placebo, for 24 weeks. The ashwagandha group lost noticeably more weight than the placebo group, about 8.5 kg compared to 2.4 kg. They also saw lower BMI, less perceived stress, fewer food cravings, and better quality of life scores. Dr. Ruscio’s Take: When stress and weight are tangled together, addressing the stress side can help more than white-knuckling the diet alone. Ashwagandha won't do the work by itself, but as an adaptogen with a good safety record, it's a reasonable addition when someone feels stuck and stressed at the same time. |

When Red Meat Triggers Delayed Symptoms, Consider a Tick Bite |
|
Some food reactions are easy to trace. Alpha-gal syndrome usually isn't. Alpha-gal is a delayed allergy to red meat triggered by a tick bite, and because symptoms show up hours later instead of minutes, it's easy to miss entirely. A meta-analysis pooled 15 studies and 1,162 patients to sharpen the clinical picture. Hives were the most common sign, showing up in about 64% of patients. Gut symptoms were close behind at 69%, including abdominal pain, diarrhea, nausea, and vomiting. A tick bite was recalled by 79% of patients, and in 92%, symptoms started at least an hour after eating red meat. On follow-up, 87% improved, with complete resolution in 43%. Dr. Ruscio’s Take: The delayed timing is exactly what throws people off. A reaction hours after dinner doesn't register as a food allergy to most people, including many clinicians. If someone has unexplained gut or allergic symptoms after red meat, and any history of tick exposure, alpha-gal belongs on the list. It's underdiagnosed largely because the timeline hides it. |

A Spore-Based Probiotic Got Things Moving |
|
Infrequent, hard-to-pass stools are common, and most people reach for fiber or laxatives first. A randomized, placebo-controlled trial tested a different approach in 144 healthy adults with sluggish bowel habits. Participants took either Bacillus coagulans (2 billion CFU/day) or placebo for four weeks. The probiotic group had more frequent bowel movements and softer, easier-to-pass stools. Broader GI symptoms, quality of life, and overall microbiota composition didn't shift, so the benefit looks specific to regularity rather than a general gut reset. Dr. Ruscio’s Take: If your main complaint is simply not going often enough, a spore-based strain like this is a gentle, targeted option worth trying before reaching for a laxative. Bacillus coagulans is one of the two strains in our own Soil-Based Probiotic, alongside B. subtilis, so it's a reasonable place to start if regularity is your main issue and you want that species specifically. |
