Influencer Grace Beverley Warns Fans After Borderline Mercury Poisoning Scare

Fitness entrepreneur and content creator Grace Beverley is issuing a vital health warning to her millions of followers after a routine blood test revealed she was on the brink of mercury poisoning. The 28-year-old founder of Tala gymwear took to TikTok on Wednesday, April 29, 2026, to share the startling results of a medical evaluation that has completely changed her diet.

Beverley, who is currently pregnant, sought medical advice after experiencing unexplained weight gain, severe inflammation, and symptoms she described as her hormones being “f–ked up.”

The ‘One-a-Day’ Habit

Like many fitness enthusiasts looking for a quick, high-protein meal, Beverley turned to canned tuna as a pantry staple.

• The Frequency: She admitted to eating one to two tins of tuna every single day, often grabbing them when in a rush at work.
• The Doctor’s Call: After hormone and gastrointestinal testing in winter 2025, her doctor called with an urgent warning. “You do know you’re meant to have two servings a week?” the doctor asked.
• The Diagnosis: The tests showed Beverley was borderline for mercury poisoning and had “incredibly high arsenic levels.” Her medical team recommended she stop eating fish entirely for several months to allow her levels to drop.

Why Tuna is Risky in High Volumes

Mercury is a naturally occurring element, but it accumulates in the ocean and is absorbed by fish. Large predators like tuna (specifically albacore and bigeye) contain higher concentrations than smaller fish.

• The Damage: According to the World Health Organization (WHO), mercury is a neurotoxin that can damage the nervous system, kidneys, and gastrointestinal tract.
• The Guidance: Health organizations typically recommend no more than two to three servings of low-mercury fish per week, with extra caution for pregnant individuals due to the risks to fetal development.

“I Need the Protein”: The Fan Reaction

The news sent shockwaves through the fitness community, where canned tuna is often viewed as the “holy grail” of low-cost, high-protein snacks.

• The Response: “Watching this as a pescatarian who eats tuna every day,” one follower commented with concern. Another echoed the sentiment: “Wait, I’ve been eating canned tuna nearly every day since Jan… I need the protein.”

Safer Protein Alternatives

For those looking to hit their macros without the heavy metal risk, nutritionists suggest diversifying your protein sources:

1. Lower-Mercury Fish: Swap tuna for salmon, sardines, or Atlantic mackerel, which are generally much lower in mercury.
2. Plant-Based Staples: Lentils, chickpeas, and edamame provide significant protein and fiber without the risk of elemental metal buildup.
3. Canned Chicken: If you need the convenience of a “tin,” canned chicken breast offers a similar protein profile to tuna with zero mercury risk.

Grace Beverley’s experience is a powerful reminder that even “healthy” foods can be harmful in excess. As she focuses on her recovery and pregnancy, her story serves as a cautionary tale for the “meal prep” generation: moderation is key, even for staples.
