Food’s Most Dangerous Ingredient Is Getting a Healthy Makeover
Imagine eating a slice of cake for breakfast. It's deliciously indulgent, but instead of your blood sugar spiking, your body processes all that sweetness as a healthy high-protein meal. It may sound like sci-fi, but this scenario is not necessarily far off.
"People with diabetes could especially benefit because sweet proteins don't trigger a need for insulin."
The Lowdown
An award-winning agtech startup called Amai is developing "sweet proteins," based on the molecular structure of naturally occuring exotic fruits. These new sugar substitutes could potentially replace artificial sweeteners and help people who are trying to curb their sugar intake. People with diabetes could especially benefit because sweet proteins don't trigger a need for insulin.
While there is a sweet protein currently on the market today called thaumatin, it's expensive, has a short shelf life, and is lacking in the taste department. But Amai's proteins taste 70 to 100 percent identical to the sweet ones found in nature. Once their molecular structure is designed through a sophisticated computing platform, they are made through fermentation, which is akin to brewing beer. These non-GMO proteins are over 10,000 times sweeter than sugar, which means much less needs to be produced and used.
Diseases like diabetes and heart disease, which are often linked to sugar overconsumption, have been on a major upswing over the last few decades, especially in the United States. According to the CDC, 100 million adults in the United States are now living with diabetes or prediabetes, which if not treated, often leads to type 2 diabetes within five years. By 2030, scientists predict cases of diabetes in the U.S. will increase by 54 percent. If sugar proteins like the type Amai is creating become widely available, these numbers could begin to decrease.
Next Up
Amai's sweet proteins are still in the research and development stage, but the Israeli startup is raising significant funding that should help expedite the process. They're also substantially upping their production ability by expanding their facilities.
Will consumers be comfortable ingesting a lab-designed food product?
And in March, the USDA and FDA announced plans to regulate cell-cultured foods, the category in which these sugar proteins would fall, so Amai researchers are hopeful they'll have an easier path to approval once their product is market ready.
Open Questions
All this progress may sound promising, but Amai still has a long way to go before the reality of healthy cake becomes tangible. Some questions to consider: Will consumers be comfortable ingesting a lab-designed food product? Will it taste enough like real sugar?
And if some products and brands begin to adopt it, will it ever overtake the real thing in popularity and make a dent in diseases like diabetes and obesity? Only time, more research, and a lot more money will tell, but in the meantime, feel free to daydream about eating entire pints of ice cream without needing to hit the gym.
When a patient is diagnosed with early-stage breast cancer, having surgery to remove the tumor is considered the standard of care. But what happens when a patient can’t have surgery?
Whether it’s due to high blood pressure, advanced age, heart issues, or other reasons, some breast cancer patients don’t qualify for a lumpectomy—one of the most common treatment options for early-stage breast cancer. A lumpectomy surgically removes the tumor while keeping the patient’s breast intact, while a mastectomy removes the entire breast and nearby lymph nodes.
Fortunately, a new technique called cryoablation is now available for breast cancer patients who either aren’t candidates for surgery or don’t feel comfortable undergoing a surgical procedure. With cryoablation, doctors use an ultrasound or CT scan to locate any tumors inside the patient’s breast. They then insert small, needle-like probes into the patient's breast which create an “ice ball” that surrounds the tumor and kills the cancer cells.
Cryoablation has been used for decades to treat cancers of the kidneys and liver—but only in the past few years have doctors been able to use the procedure to treat breast cancer patients. And while clinical trials have shown that cryoablation works for tumors smaller than 1.5 centimeters, a recent clinical trial at Memorial Sloan Kettering Cancer Center in New York has shown that it can work for larger tumors, too.
In this study, doctors performed cryoablation on patients whose tumors were, on average, 2.5 centimeters. The cryoablation procedure lasted for about 30 minutes, and patients were able to go home on the same day following treatment. Doctors then followed up with the patients after 16 months. In the follow-up, doctors found the recurrence rate for tumors after using cryoablation was only 10 percent.
For patients who don’t qualify for surgery, radiation and hormonal therapy is typically used to treat tumors. However, said Yolanda Brice, M.D., an interventional radiologist at Memorial Sloan Kettering Cancer Center, “when treated with only radiation and hormonal therapy, the tumors will eventually return.” Cryotherapy, Brice said, could be a more effective way to treat cancer for patients who can’t have surgery.
“The fact that we only saw a 10 percent recurrence rate in our study is incredibly promising,” she said.
Few things are more painful than a urinary tract infection (UTI). Common in men and women, these infections account for more than 8 million trips to the doctor each year and can cause an array of uncomfortable symptoms, from a burning feeling during urination to fever, vomiting, and chills. For an unlucky few, UTIs can be chronic—meaning that, despite treatment, they just keep coming back.
But new research, presented at the European Association of Urology (EAU) Congress in Paris this week, brings some hope to people who suffer from UTIs.
Clinicians from the Royal Berkshire Hospital presented the results of a long-term, nine-year clinical trial where 89 men and women who suffered from recurrent UTIs were given an oral vaccine called MV140, designed to prevent the infections. Every day for three months, the participants were given two sprays of the vaccine (flavored to taste like pineapple) and then followed over the course of nine years. Clinicians analyzed medical records and asked the study participants about symptoms to check whether any experienced UTIs or had any adverse reactions from taking the vaccine.
The results showed that across nine years, 48 of the participants (about 54%) remained completely infection-free. On average, the study participants remained infection free for 54.7 months—four and a half years.
“While we need to be pragmatic, this vaccine is a potential breakthrough in preventing UTIs and could offer a safe and effective alternative to conventional treatments,” said Gernot Bonita, Professor of Urology at the Alta Bro Medical Centre for Urology in Switzerland, who is also the EAU Chairman of Guidelines on Urological Infections.
The news comes as a relief not only for people who suffer chronic UTIs, but also to doctors who have seen an uptick in antibiotic-resistant UTIs in the past several years. Because UTIs usually require antibiotics, patients run the risk of developing a resistance to the antibiotics, making infections more difficult to treat. A preventative vaccine could mean less infections, less antibiotics, and less drug resistance overall.
“Many of our participants told us that having the vaccine restored their quality of life,” said Dr. Bob Yang, Consultant Urologist at the Royal Berkshire NHS Foundation Trust, who helped lead the research. “While we’re yet to look at the effect of this vaccine in different patient groups, this follow-up data suggests it could be a game-changer for UTI prevention if it’s offered widely, reducing the need for antibiotic treatments.”
