LONDON: British scientists have developed a far more accurate blood test to diagnose peanut allergy, offering a better way to monitor a significant food hazard.
Peanuts are the most common cause of fatal food-induced anaphylaxis, or severe allergic reaction, and allergy cases among children have risen sharply in recent years. Britain’s Food Standards Agency estimates up to one in 55 children have a peanut allergy.
In contrast to existing skin-prick and other blood tests that produce a large number of false positive results, the new diagnostic has 98 percent specificity, researchers from the Medical Research Council (MARC) reported on Thursday.
Current tests, in use for decades, are based on looking for antibodies — but they cannot differentiate between sensitivity and true food allergy.
As a result, doctors often have to conduct a further round of testing in which patients are fed incrementally larger doses of peanut in a controlled hospital setting to confirm their allergy, a process that can itself trigger anaphylactic shock.
So-called oral food challenges require the presence of an allergist and specialist nurses and they cost around £1,000 to conduct. The new blood test is five times cheaper.
Dr. Alexandra Santos, an MRC scientist and pediatric allergist at King’s College London, who led the research, believes the new test will not only save money on testing but also reduce by two-thirds the number of stressful oral food challenges that are needed.
The development of the new test follows advances in science that allow the detection of biological signals from much small blood samples than in the past.
“The technology has evolved. Now we have better ways to look at immune cells and to see how they respond,” Santos said.
The new tests focus on mast cells, which play a pivotal role in triggering allergic symptoms, such as skin reactions or constricting of the airways.
In a study involving 174 children, published in the Journal of Allergy and Clinical Immunology, Santos and colleagues showed the new test tracked closely the severity of allergies, with the worst-affected patients having the most activated mast cells.
The team is now discussing plans for the widespread roll-out of the test with an unnamed commercial partner. There are also plans to adapt it to other foods, such as milk, eggs, sesame and tree nuts.
There are currently no approved drugs for peanut allergies, although two biotech companies — US-based Aimmune Therapeutics and France’s DBV Technologies — are working to develop rival treatments.

Where We Are Going Today: ‘Phet Phet’ Thai restaurant in Riyadh
Located at Pure Center on Takhassusi Road, Phet Phet is one of the boldest Thai kitchens to hit Riyadh — and it lives up to its name, which literally means “very spicy.”
With its neon signs, playful branding, and sleek modern seating, the place feels like a Bangkok street stall reimagined with modern aesthetics.
The menu leans heavily into bold, unapologetic flavors. I started with the shrimp cashew for SR75 ($20) — a standout dish that combined sweet, savory, and spicy notes perfectly, with just the right crunch.
Another favorite was the tom yum nam khon for SR 55, a rich and creamy soup layered with lemongrass, lime, and plump shrimp. It was intense and comforting at the same time.
Among the many appetizers we tried, the pow pow shrimp, chili wontons, and prawn toast all delivered.
The pad ki mao chicken and panang curry chicken were flavorful, with deep spice profiles that felt authentic. Even side dishes like sticky rice, coconut rice, and the playful Kinza cola added to the experience.
For dessert, the mango sticky rice (SR 35) offered a cool, sweet end to the fiery meal.
The place runs on energy — fast service, loud tables, and constant movement from the open kitchen to the packed dining area.
But here’s the only downside: Phet Phet is small. With how popular it already is, the space can feel cramped, and getting a seat without a wait is tricky.
Still, for those who love real heat, bold flavors, and a vibe that feels straight out of Thailand, Phet Phet is a must-visit.

Where We Are Going Today: ‘Noria Furn’ bakery in Riyadh
- Noria Furn is a charming bakery with an early closing time that makes it ideal only for those who rise with the sun
Nestled in the lively Rayyan district of eastern Riyadh, Noria Furn is bakery that specializes in Middle Eastern breakfast staples.
Open from 6 a.m. to 1:30 p.m., it is an ideal spot for early birds eager to indulge in freshly baked goods, such as pies, mankoosha, falafel, and more.
The smell of freshly baked bread sets the tone as you enter, offering an appetizing and warm welcome.
On recent visits, I was impressed by the attentive and welcoming service, even when the outlet was bustling with customers.
Each dish I tried, from the taghmeesat shakshouka to the akawi cheese, was fresh, flavorful, and artfully presented. The cozy atmosphere, enhanced by the absence of background music, creates an inviting space for a leisurely meal.
However, there are areas for improvement. Prices are on the high side, which might not suit every budget, even if the quality largely justifies the cost.
I noticed their hot drinks, such as karak and tea, did not stay warm long enough. Using kettles with a base to maintain temperature could greatly enhance the overall experience.
While the tandoor bread was delightful, offering a wheat option would accommodate a wider range of dietary preferences.
Noria Furn is a charming bakery with an early closing time that makes it ideal only for those who rise with the sun. I look forward to returning and seeing how they continue to develop their offerings.
Where We Are Going Today: ‘Sign’ burgers in Riyadh
- One of the highlights was the Sign box, which includes four burgers and four fries, ideal for gatherings
If you’re in Riyadh and looking for a burger spot that delivers on both taste and value, Sign should be on your list.
With eye-catching pink branding and loyal customers, it is clear they have tapped into a winning formula: simple, good food done right.
I tried their classic burger meal, which includes fries and a drink, and was genuinely surprised to get all that flavor for just SR24 ($6.40). The patty was juicy, the bun soft, and the sauce had the perfect tang without overpowering the rest of the ingredients. It felt well-balanced and satisfying, not greasy or heavy.
One of the highlights was the Sign box, which includes four burgers and four fries, ideal for gatherings. Sign uses locally sourced ingredients from Saudi farms, which is also a major plus — you can taste the difference in the quality of the meat and vegetables.
Whether you’re grabbing a quick bite through their drive-thru or sitting down with friends, it’s a spot that gets it right without overcomplicating things.
If there is one downside, it is the wait. The place is almost always packed — a sign (no pun intended) of how popular it has become. But if you are happy to queue, it is absolutely worth checking out.

- The lights are dimmed every Tuesday night for a candlelit experience with a pianist playing live music, creating an atmospheric experience for guests
With four locations across the Kingdom’s capital, Avindar Lounge offers a space where you can enjoy lush greenery and good food.
The lounge I visited is located on the northeast side of Riyadh and includes a separate section for smokers.
The menu is diverse and appeals to different tastes, so you can sample anything from Middle Eastern kebabs to pasta and burgers.
The lights are dimmed every Tuesday night for a candlelit experience with a pianist playing live music, creating an atmospheric experience for guests.
I tried the mixed appetizer, which was flavorful and memorable. It included hummus, tabouli, dolma, and baba ghanoush.
And while I am generally not a fan of sweet beverages, I genuinely enjoyed their hot chocolate, which was not overwhelmingly sweet or creamy.
However, considering the portion sizes, which are enough for one person, customers might find the prices a bit high.
But the music and bird sounds, paired with the lounge’s colorful and cozy interior, make Avindar a refreshing spot for dining or coffee with friends.
Where We Are Going Today: ‘Dakkat Haretna’ restaurant in Riyadh
Located in the bustling Al-Munsiyah neighborhood of Riyadh, Dakkat Haretna is a charming eatery that captures the essence of Saudi Arabia cuisine.
The interior is adorned with Qatt Asiri art, traditional Saudi motifs that resonate with the spirit of the region. The windows, designed in the Hijazi roshan style, add to the charming appeal of the space which is cozy and family friendly.
Behind the menu is chef Douha Al-Otaishan, whose vision brings to life dishes that celebrate the rich culinary heritage of Saudi Arabia.
I sampled the beetroot salad, which had refreshing ingredients, complemented by feta cheese balls and crisp lettuce, that set the stage for the main course.
The marqooq beef and “happiness kabsa,” Al-Otaishan’s signature dish, were both memorable. I polished off the flavorful marqooq in no time.
The kabsa, with its tender chicken, was delightful despite the rice being a tad drier than what I usually enjoy. The accompanying tangy red sauce elevated the dish by adding a burst of flavor.
Other notable options for those wishing to explore Saudi cuisine are jareesh, qursan, and kubaiba Hail.
Their breakfast menu is equally enticing, providing classics including tamees, foul, and shakshooka, available from 7 a.m.
If you enjoy cooking and want to recreate Saudi dishes at home, the restaurant also offers the chef’s blends of spices.
With attentive service, fair prices, and a calm ambiance free of noisy music, Dakkat Haretna is a comfortable place to enjoy traditional dishes or try something new.
Whether you are familiar with Saudi cuisine or just curious, it is a spot worth visiting.
