Vaping and e-cigarettes could ‘harm your DNA’ and ‘increase risk of cancer’

DUBAI: Electronic cigarettes, or e-cigarettes, can increase the risk of heart disease and cancer, as well as damage DNA, according to a recent study from the Proceedings of the National Academy of Sciences.
Despite being promoted as “safer” alternatives to cigarette tobacco, the study claims the battery-driven devices could still pose grave health consequences.
“We propose that ECS (e-cigarette smoke) is carcinogenic and that e-cig smokers have a higher risk than non-smokers to develop lung and bladder cancer and heart diseases,” researchers wrote.
According to tests run on mice, those that were exposed to smoke from e-cigarettes had higher levels of DNA damage in the bladder, heart and lungs as opposed to those breathing regular filtered air.
But the repair systems that protect against cancer in the mice that were exposed to e-cigarette fumes were also damaged.
“It is important to note that many e-cig smokers (who) have taken up the e-cig smoking habit are not necessarily doing it for the purpose of quitting TS (tobacco smoking), rather, it is because they are assuming that e-cig smoking is safe,” the scientists wrote.

Where We Are Going Today: Yu by Toki Restaurant in Riyadh

  • One order comes with two rolls on a plate, perfect for those looking to share one of the best dishes on the menu

Bringing its flavors from Toki in Jeddah, Yu by Toki is in Riyadh at Mamlaka Social Dining, tucked into a back corner, where the Chinese restaurant offers dishes inspired by Cantonese and Szechuan cuisine, with a modern twist.

At Mamlaka Social Dining, guests order directly from each restaurant’s booth before choosing a table within the shared dining area. Many opt for the outdoor terrace, which offers sweeping views of Riyadh from the iconic tower.

Yu’s one-page menu is concise yet diverse in options, with a particular focus on starters and dim sum. The starters introduce the menu’s flavor palette.

To start, I opted for the Szechuan crispy duck roll which comes wrapped in homemade pancake and stuffed with cucumber and spring onion alongside the crispy duck meat.

One order comes with two rolls on a plate, perfect for those looking to share one of the best dishes on the menu. The crunchy duck meat, fresh cucumber, and sweet sauce provides a balanced and delicious starter experience.

Another popular dish — often sold out — is the bang bang chicken, served with chili and pandan cream for a bold, spicy kick. For a milder option, the smoked corn chicken offers a deeper, caramelized flavor profile.

When it comes to buns and dumplings, I would go for either the baked smoked angus bun or the Szechuan sui mai.

If you are looking for something on the heavier side, the baked smoked angus bun is intense with strong flavors of beef paired with a sauce and fluffy bun.

On the other hand, the Szechuan sui mai is a light and fresh dish, paired with soybean, chili, Chinese mushrooms, and spring onion.

For the main course, I selected the sweet and sour chicken and paired it with the vegetable noodles.

Unfortunately, Yu by Toki’s does not offer dessert, which can be disappointing for those looking to indulge in Chinese varieties. Mamlaka Social Dining solves this by offering a vast array of options.
