Watch nowIf you're struggling to remember things, a robust workout might help. Scientists have discovered that exercise can increase levels of brain-derived neurotrophic factor (BDNF), a protein that supports learning and memory. A recent study in rats found that low-speed uphill exercise raises blood lactate levels, increasing lactate and BDNF in key brain regions involved in cognition. Researchers divided rats into three groups: One remained inactive, another walked on a flat treadmill, and a third walked uphill at a 40% incline. The exercise sessions lasted either 30 or 90 minutes. To see if lactate... exercise brain memory bdnf lactate

Watch nowFlaxseed oil is rich in alpha-linolenic acid (ALA), a precursor to docosahexaenoic acid (DHA), an omega-3 fatty acid critical for infant brain and eye development. A recent study found that supplementing the diets of lactating women with flaxseed oil altered the levels of some omega-3 fatty acids in breast milk, plasma, and red blood cells but not DHA. The study involved seven lactating women who consumed 20 grams of flaxseed oil daily for four weeks. Researchers collected and analyzed samples of the participants' breast milk and blood before, during, and after the supplementation period to a... omega-3 development breast milk
Read moreEvidence demonstrates that lactate, once considered a metabolic waste product, participates in diverse roles in metabolism, sensing, and signaling under normal and pathological conditions. Its functions range from influencing muscle adaptation and heart fueling during exercise to moderating insulin release, carcinogenesis, and various aspects of health, including neurobiology and nutrition. This review describes the multiple roles of lactate in human physiology. ... nutrition exercise cancer aerobic lactate
Read moreLactate boosts cognitive function in mice, according to a new study. Mice had better spatial working and long-term memory after exercising and receiving supplemental lactate. Researchers studied the effects of exercise – with or without supplemental lactate – on cognitive function in mice. The mice engaged in moderate-intensity exercise (about 55 to 60 percent of their VO2 max) five days a week for five weeks. This level of intensity is just below the "lactate threshold" – the point at which lactate builds up in the bloodstream and compromises performance. At the end of the five-week period, ... exercise brain dementia bdnf lactate
Read moreLactate is a compound that is produced primarily in the muscles via the breakdown of glucose during exercise. It can be "shuttled" from the muscles to various tissues, including the heart, and brain, where it can be used as an energy source. Evidence from a recent study suggests that lactate rejuvenates immune cells that target cancer. Specialized immune cells called CD8+ T cells are the primary drivers of anti-tumor immunity. During cancer progression, CD8+ T cells can experience "exhaustion," (https://www.frontiersin.org/articles/10.3389/fimmu.2020.622509/full) a dysfunctional state caused ... exercise cancer lactate
