Health Alert: Fatty Liver Disease May Increase Risk for Heart Failure. Non-alcoholic fatty liver disease (NAFLD) is a condition that occurs when fat accumulates in the liver from causes other than excessive alcohol consumption, and it is associated with a number of poor health outcomes. Following an analysis of national health survey data from 2005-2018, researchers report that NAFLD patients are 3.5 times more likely to develop heart failure than individuals with healthy liver function.                                                                                        American Heart Association, November 2022

Diet: A Low-Carb Diet Might Raise Type 2 Diabetes Risk. Past research has shown that a low-carbohydrate diet can lower the risk for type 2 diabetes, but a recent study suggests this may not always be the case. Researchers analyzed data concerning over 200,000 adults and found that individuals on a low-carb diet featuring protein and fat that is primarily from animal-based sources had a 35% increased risk for type 2
diabetes.                                                                                          American Heart Association, November 2022

Exercise: When Is Exercise Too Intense for the Heart? When exercising, it’s important to elevate your heart rate enough to get a good workout, while not too high as to place unnecessary stress on the heart. The American College of Sports Medicine recommends keeping your heart rate below 85% of your maximum heart rate, which is calculated by subtracting your age from the number 220. For example, a 50-year-old man should keep their heart rate under 144.5 beats per minute. WebMD, November 2022

Diet: Unhealthy Diet Linked to Depression. Kynurenic acid is a normal byproduct of the metabolism of tryptophan, which is known to affect neurophysiological and neuropathological processes. A recent study that included 169 adults found that those who consumed a Western-style diet had lower levels of kynurenic acid and a higher risk for depression than participants who consumed a healthier diet. Neuroscientist Dr. Edwin Lim explains, “Western-style diets high in fat, sugar, and processed foods were already known to increase the risk of depression, but this is the first time a biological link involving the kynurenine pathway has been established… People from the
group eating an unhealthy diet had lower levels of [kynurenine acid] and more severe symptoms of depression. This indicates that [kynurenine acid] may help to protect us against depression.”                                                                              Frontiers in Nutrition, October 2022
