Liquid Apple Cider Vinegar May Help Reduce Depression Symptoms
Acetic acid is the main compound found in vinegar. It has anti-bacterial properties and has been used for centuries as a digestive aid. A new study has found that daily consumption of apple cider vinegar in liquid form may help reduce depression symptoms by up to 34%.
25 healthy adults with an average age of 21 participated in the study. Half consumed 2 tablespoons of apple cider vinegar containing 1.5 grams of acetic acid diluted in 1 cup of water twice daily with meals for 4 weeks. The other half consumed a vinegar tablet containing 0.015 grams of acetic acid daily for 4 weeks.
Participants completed the Profile of Mood States and the Center for Epidemiological Studies-Depression questionnaires at baseline and at week 4. The questionnaires assessed tension, depression, anger, fatigue, confusion and vigor. Urine samples were used to evaluate metabolite levels.
Participants in the apple cider vinegar group saw a 20-34% decrease in depression scores compared to slight increases in the vinegar tablet group. They also saw significant increases in the metabolism of acetate.
The study was conducted by researchers from Arizona State University. It was published online ahead of print on November 9, 2021 in the journal Nutrients.
