Memory, attention, and energy all start to decline as we get older. A recent study suggests that taking curcumin supplements may improve attention, fatigue, and working memory in mature adults.
Participants in the study included 60 healthy people between the ages of 60 and 85 who were given either 80 mg of curcumin or a placebo every day for four weeks. One hour after taking the supplements, the researchers tested attention and working memory and found that the curcumin group showed improvements in both.
Working memory and fatigue were also improved in the curcumin group following four weeks of supplementation. The curcumin group experienced an average 1.82% decrease in fatigue following a mental challenge, while the placebo group had a 17% increase in fatigue. Additionally, measures of calmness and contentedness were higher in the curcumin group.
Researchers from the University of Melbourne conducted the study. It was published on October 2, 2014, in the Journal of Psychopharmacology.
Curcumin has been used in folk remedies for years to ease menstrual cramping, help heal wounds, and to improve the appearance of skin. Recent studies have suggested that it may also protect against prostate cancer, Alzheimers, diabetes and arthritis. All of these benefits are attributed to the anti-inflammatory properties of curcumin.
A recent study suggests that eating a breakfast rich in protein from dairy - but not from soy - may stimulate mTOR (mammalian target of rapamycin). mTOR is an enzyme that is the primary regulator of muscle protein synthesis.
Participants in the study included 10 healthy men and 10 men with metabolic syndrome (MetS). Metabolic syndrome is the group of risk factors that contribute to coronary artery disease, stroke, and type-2 diabetes. The risk factors include high blood pressure, insulin resistance, large waist circumference, high triglyceride levels and high cholesterol.
Half of the men ate a breakfast with a dairy protein while the other half ate a calorie-matched breakfast with soy protein. The researchers took muscle biopsies two and four hours after the meals. They found that mTOR levels were higher at the two- hour mark in the dairy group, but not the soy group. They also found higher levels of ribosomal protein S6 phosphoylation in that group. Ribosomal protein S6 phosphoylation is required for protein synthesis in human skeletal muscle.
The men with MetS showed no changes in mTOR levels.
Researchers from Deakin University conducted the study. It was published on September 30, 2014, in Nutrition & Metabolism.
Dairy consumption has also been linked to bone health, diabetes prevention, weight loss, and improved mental function. If youre looking to add more dairy to your diet, consider sticking to the low-fat dairy products as the high fat content of whole milk products could negatively affect other areas of the body.
