Single dose of medical LSD shows promise in reducing anxiety

About 4% of the global population lives with an anxiety disorder, such as generalized anxiety disorder (GAD). While there are currently treatment options available for GAD, past studies show that about 50% of people will not respond to first-line treatments like antidepressant therapy. A new study reports the results of a phase 2b clinical trial of an LSD medication that shows promise in treating anxiety. The drug, called MM120, is an oral pharmaceutical form of LSD, the hallucinogenic drug also known as acid.

Keto diet may affect aging speed differently in males and females

A new study in mice found that a ketogenic diet did not accelerate the aging of females, although it did cause males to age more rapidly. The authors of the study found that the presence of estrogen in the female mice blocked the aging effect of the diet. When males were treated with estrogen, estradiol, and antioxidants, the rapid-aging effects of the diets decreased. Further study is required to determine if these effects translate to humans.

Eating breakfast late linked to biological aging, depression, and oral health issues

Past studies show that certain healthy lifestyle habits, such as eating a nutritional diet, can help people live longer and healthier. A new study found the time of day people eat their meals — especially breakfast — may also affect longevity. Eating breakfast later in the day, for example, was linked to depression and oral health issues.

Why potassium supplements might help lower heart failure risk

A new trial investigating high-normal serum potassium levels for people at high risk of ventricular arrhythmias delivered promising results. Compared to a control group, people with these elevated potassium levels fared better over the approximately 3 years of the trial. Too little potassium is bad for the heart, and so is too much. The trial suggested a new sweet spot for at-risk heart patients.

7 sugar substitutes linked to 62% faster decline in thinking, memory skills

Low-calorie sweeteners and sugar substitutes such as aspartame, saccharin, and xylitol have been used since the early 1900s. Past studies show there may be potential health risks to using sugar substitutes, including cognitive issues. A new study provides more evidence suggesting a correlation between sugar substitute use and cognitive decline.

Beta-blockers may be harmful for women with some heart conditions

Beta-blockers are a type of medication used after heart attacks. A recent study suggests that using beta-blockers does not improve certain outcomes after heart attacks where the left ventricular ejection fraction is preserved. Further analysis suggests that beta-blocker use may be harmful for women, especially for those who take beta-blockers at higher doses and for women who have preserved left ventricular ejection fraction.

Routine eye exams may help spot early signs of Alzheimer's

One way scientists think Alzheimer’s disease may be detected early is through eye health. Specifically, scientists have been looking into the retina and its blood vessels in hopes that they could help identify changes that are also occurring in the brain. Results of a recent mouse study suggest distinct vascular changes in the eyes and brain occur at the same time, and that closer eye examination could ultimately help doctors detect Alzheimer’s and related dementias sooner.

IBS, vitamin D deficiency may predict Alzheimer's, Parkinson's disease

Currently, neurodegenerative conditions, such as Parkinson’s and Alzheimer’s diseases, are challenging to preempt. A large-scale, innovative new study investigates how hormonal, dietary, metabolic, and digestive issues may help predict these conditions years before they begin. The study identifies several conditions that are associated with an increased risk of Alzheimer’s and Parkinson’s. Importantly, the findings also hint at ways to help reduce the risk of developing these disorders.

Could eating more broccoli help lower your colon cancer risk?

Colorectal cancer is the third most common cancer in the world. Colon cancer diagnoses under the age of 50 are on the rise for a number of reasons, including eating a diet high in processed foods. Past studies show that focusing on certain types of foods may help lower a person’s colon cancer risk. A new study says consumption of cruciferous vegetables may help decrease colon cancer risk.

Mediterranean diet may slow cognitive decline in those at high genetic risk

Previous studies have identified specific genetic variants that may increase a person’s risk for Alzheimer’s disease, such as the APOE4 variant. A new study found that following a Mediterranean diet may help lower a person’s risk of developing dementia and decelerate cognitive decline. Scientists discovered that this protective effect was strongest in high risk participants with two copies of the APOE4 gene variant.

Low-calorie Mediterranean diet and exercise may help lower diabetes risk

About one in every nine adults around the world lives with diabetes, with 90% of them having type 2 diabetes. Past studies show that certain lifestyle factors can help lower a person’s risk for type 2 diabetes, such as exercising regularly and eating a healthy diet like the Mediterranean diet. A new study has found that a combination of following a calorie-restricted Mediterranean-style diet, plus moderate exercise and following a weight-loss program, is a more effective way to lower type 2 diabetes risk compared to only following the Mediterranean diet.

3 diet types may help reduce chronic disease risk in older adults

Researchers from Karolinska Institutet studied how dietary patterns influence the development of chronic diseases such as heart disease, dementia, and diabetes in older adults. Older adults who regularly ate healthier diets that included vegetables, whole grains, nuts, and healthy fats experienced a slower buildup of chronic illnesses. Those who consumed more red meat, processed foods, and sugary beverages were more likely to develop multiple chronic conditions over time.
