A push to eliminate food dyes gains momentum nationwide, according to RFK Jr.

The movement to ban synthetic dyes in food across the US is gaining momentum, driven by critics who argue that these dyes pose a problem that should not be ignored.

States like West Virginia are referencing the Make America Healthy Movement, led by Health and Human Services Secretary Robert F. Kennedy Jr., as a key driving force. There is no established monitoring for this issue.

In the first three months of the year, 20 states, including Oklahoma, West Virginia, and New York, have introduced nearly 40 bills aimed at restricting artificial dyes and other food additives, the highest number in any year according to the Environmental Working Group, a food safety advocacy group.

Advocate Brandon Cowd, who with his wife Whitney created the film “Documentary” cited by West Virginia lawmakers, expressed optimism about the progress being made. “We have bills on the table in states like Oklahoma, Tennessee, Florida, New York, Texas, and Arizona. There is a strong showing from all these states,” Cowd said.

The FDA has approved 36 color additives, including nine synthetic dyes used in food and beverages. Despite their approval, concerns have led to bans on certain dyes like Red No. 3 in January due to potential cancer risks.

These synthetic dyes are commonly found in products marketed to children such as candies, breakfast cereals, and soda, due to their bright and eye-catching colors.

Recently, West Virginia lawmakers passed a bill to ban seven dyes, including Red 40 and Green 3, effective 2028 upon the governor’s signature. This follows a previous ban on six dyes from foods served in public schools, similar to actions taken in California.

Lawmakers in Arizona also discussed a bill to ban certain chemicals, including synthetic dyes, from foods served in public schools.

Kennedy advocates for the elimination of artificial dyes

While the FDA has not established direct links, some government officials and groups claim a connection between these dyes and health issues.

Harvard nutrition professor Jerrold Mande noted the increasing attention to this issue and credited grassroots movements for the shift in focus. Studies have suggested possible links between dye consumption and behavioral issues in children.

Kennedy has been a vocal advocate for the elimination of artificial dyes, citing reports that indicate these dyes could disrupt normal behavior in children. He also plans to address major food company executives on this issue.

While scientific evidence regarding the effects of artificial dyes on health is inconclusive, many state lawmakers have taken action based on precautionary principles, pointing to stricter regulations in European countries.

Consumers like Wendy Bacos and Liz Dent have taken the initiative to avoid foods containing artificial dyes for their children, citing health concerns and seeking out alternatives to these additives.

Physicists generate quantum tornadoes in momentum space

Physicists have long known that electrons can form vortices from quantum materials. What's new is evidence that these small particles create tornado-like structures in momentum space.

Momentum space is a fundamental physics concept that explains electron motion in terms of energy and orientation rather than precise physical location.

The counterpart, the position space, is an area where familiar phenomena such as water vortices and hurricanes occur.

Until now, even quantum vortices of materials have been observed only in positional space.

Eight years ago, Dr. Roderrich Mossner of the Max Planck Institute for the Physics of Complex Systems and the Excellence ct.qmat of the Würzburg Denden cluster theorized that quantum tornadoes could also form in momentum spaces.

At the time, he described this phenomenon as a smoke ring. Because, like a ring of smoke, it is made up of vortices.

But up until now, no one knew how to measure them.

To detect quantum tornadoes in momentum space, Dr. Moessner and colleagues have enhanced a well-known technique called ARPES (angle-resolved light emission spectroscopy).

“ARPES is a fundamental tool in experimental solid-state physics,” explained Dr. Maximilian ünzelmann, researcher at the University of Werzburg, the experimental Physik VII and the Würzburg-Dresden Cluster of Excellence Cluster.

“It involves shining light on a material sample, extracting electrons, and measuring energy and outlet angles.”

“This allows us to see the electronic structure of the material directly in the momentum space.”

“By skillfully adapting this method, we were able to measure orbital angular momentum.”
