Effects of Curcumin Supplementation on Inflammatory Markers, Muscle Damage, and Sports Performance during Acute Physical Exercise in Sedentary Individuals

Universidade Federal de Viçosa (Brazil), December 14, 2021 Exhaustive and acute unusual physical exercise leads to muscle damage. Curcumin has been widely studied due to the variety of its biological activities, attributed to its antioxidant and anti-inflammatory properties. Furthermore, it has shown positive effects on physical exercise practitioners. However, there is no literature consensus on the beneficial effects of curcumin in acute physical activities performed by sedentary individuals. Therefore, we systematically reviewed evidence from clinical trials on the main effects of curcumin supplementation on inflammatory markers, sports performance, and muscle damage during acute physical exercises in these individuals. Most studies have shown positive effects of curcumin supplementation in sedentary individuals undergoing acute physical exercise. Overall, participants supplemented with curcumin showed less muscle damage, reduced inflammation, and better muscle performance.


Long Term Study Alludes to Artificial Sweeteners and Cognitive Decline Link

University of Barcelona, December 10. 2021 Diet is considered an important modulator of cognitive decline and dementia, but the available evidence is, however, still fragmented and often inconsistent. Methods and Results In conclusion, our prospective and validated data suggest that food-related and microbiota-derived metabolites may play an important role in the later development of CD. Our results support a protective association between metabolites reflecting the consumption of polyphenol-rich foods (i.e., fruits and vegetables), cocoa, coffee, mushrooms and red wine with CD, whereas other food components related to unhealthy dietary components (i.e., alcohol, artificial sweeteners) may have deleterious effects on cognition.


Key role in brain health for vitamin E

University of Newcastle (Australia), December 18, 2021 Vitamin E has a key role to play in reducing the onset of Alzheimer’s disease, fatty liver diseases and other health risks, experts at a recent symposium on vitamin E have said. Eggersdorfersaid that more than 90% of the US’s population did not meet their recommended daily allowance of vitamin E, which was a worry. Consumers were expected to take in enough vitamin E through their diets, but “they are characterised by an increasing intake of processed foods”, said Lisa Wood, associate professor at the Centre for Asthma and Respiratory Diseases at Australia’s University of Newcastle.


Childhood obesity linked with mother's unhealthy diet before pregnancy

University of Southampton, December 22, 2021 New research led by the University of Southampton shows supporting women to eat a healthy diet pre-pregnancy could reduce risk of obesity for their children. New research, at the University of Southampton, has found children aged eight or nine were more likely to be obese if their mother had a poor diet during—and before—pregnancy. The research identifies these as critical times, when initiatives to reduce childhood obesity may be more effective. The results, published in the International Journal of Obesity, showed that if a mother-child pair was in a lower diet quality group, this was associated with child having a higher DXA percentage body fat and BMI at age eight or nine. This research shows the importance of intervening at the earliest possible stage in a child's life, in pregnancy or even before conception, to enable us to tackle it."


Can Oily Fish, Cherries Or Milk Help You Sleep? Here’s What The Evidence Shows

Aston University (UK), December 20, 2021 Almost one-in-five British people report they don’t get enough sleep each night. The problem is so bad that in total the UK public are losing around a night’s worth of shut-eye each week. Our diet has an influence upon sleep patterns by affecting the sleep hormone melatonin. For example, foods rich in the essential amino acid tryptophan are commonly cited as helping sleep, as tryptophan helps produce melatonin. Additionally, some vitamins and minerals may help sleep, such as vitamin D, magnesium and zinc. Oily fish: Evidence suggests the more oily fish, such as salmon or herring, you eat the better you sleep. Oily fish contain healthy fats such as omega-3 oils which have been shown to improve sleep in children and are involved in serotonin release. Tart cherries: Evidence suggests that tart cherries improves sleep in older adults, probably due to their ability to increase melatonin levels. And tart cherries are also rich in nutrients, including magnesium, which also may improve your sleep. Warm milk: Research conducted in the 1970s suggested that a glass of warm milk before bed could improve sleep quality. This research was performed in a very small group however, and little research has been done since. Drinking milk does increase melatonin levels which could help. But there isn’t enough evidence to support the claim that a glass of warm milk definitely makes you nod off. Herbal teas: Evidence for valerian, a common ingredient, to aid sleep is inconclusive. Decaffeinated green tea has been reported to improve sleep quality, which might be linked to the relaxing qualities of L-theanine, an amino acid it contains


War metaphors for cancer hurt certain prevention behaviors

University of Michigan, December 15, 2021 It's not unusual for people to use war metaphors such as "fight" and "battle" when trying to motivate patients with cancer. But a new University of Michigan study indicates that using those words can have an unintended negative effect. David Hauser, a U-M doctoral student in psychology, and colleague Norbert Schwarz of the University of Southern California, found in three studies that exposure to metaphoric language relating cancer to an enemy significantly lessens the extent to which people consider cancer-prevention behaviors.
