In recent years, natural products such as kratom, which derives from a Southeast Asian tree called Mitragyna speciosa, and cannabidiol (or CBD) which derives from the Cannabis plant, have gained significant popularity for their potential to relieve anxiety, manage pain, and enhance mood. While both substances are often praised by users for their plant-based origins, and are often considered safer than synthetic pharmaceuticals as a result, the scientific community is working to uncover the complexities behind how these compounds interact, not just with the human body but with each other. After all, plant-based compounds are still active, and have the same potential for benefit and harm as any drug. People who use kratom are also more likely to use CBD, meaning that they could potentially experience a drug interaction if both substances are ingested around the same time. A recent study by Dr. Erin Berthold and her colleagues at the University of Florida sheds new light on the pharmacokinetic interactions between kratom and CBD, revealing findings that are both fascinating and important for public health.

We think of our brains as safe and secure within our skulls, and not easily influenced unless we consume a mind-altering substance, suffer a traumatic injury or undergo invasive brain surgery. However, recent research shows that our brain activity can be influenced non-invasively using nothing but sound and that this technique could have therapeutic potential. As a postdoctoral researcher at UC Berkeley, Dr. Ben Sorum began to think about these types of question while in the Lab of Dr. Stephen G. Brohawn. Now, Dr. Sorum’s current research at Cooper Medical School of Rowan University explores how ultrasound, which can be non-invasively administered from outside the brain and through the skull, can activate specialized proteins in brain cells, changing their activity. The technique, if further developed, may play a key role in the future of neuromodulation, a field with enormous potential for treating neurological disorders.

In recent years, plant-based diets have gained significant traction, not just among vegetarians and vegans but also among individuals looking to improve their health and reduce their environmental impact. Increasing public awareness of the role of animal food production in driving climate change, along with the potential health risks of consuming large amounts of animal foods has powered this phenomenon. However, one of the ongoing debates in nutrition revolves around protein, a crucial nutritional component, and the nutritional quality of various protein sources. Can plant-based protein sources provide sufficient, high-quality protein compared with animal-based protein sources in the context of a dietary pattern? The question relates to consumer awareness and education, as not all plant proteins are created equal, and replacing meat, diary, and other animal proteins with just one or two plant protein sources may not provide everything we need nutritionally. Rather, a mix of plant protein sources may be required as an adequate replacement for high quality animal protein. As consumers increasingly replace animal proteins with plant proteins, potentially without awareness of these issues, is the overall quality of the protein they are consuming decreasing? Dr. Christopher Marinangeli of Protein Industries Canada and his colleagues set out to answer this question in their research on the effects of increasing plant protein intake on protein quality and nutrient consumption among U.S. adults.
