Recently, our focus has been on heart health, eye health, weight loss medications, and nutrition, brought to you by MNT Design and photography by DZ FILM/Stocksy, BONNINSTUDIO/Stocksy, & Ángela Rober/Stocksy. We have gathered the latest notable news in health and well-being, centering on heart health, GLP-1 medications for type 2 diabetes and weight loss, and cholesterol. Within our selected studies, we explore the debated link between eggs and cholesterol, the impact of GLP-1 drugs on eye and heart health, and a supplement that may reduce the risk of heart disease. We provide insights on the limitations and new discoveries from these research pieces, along with suggested articles for further reading. Amidst our coverage of peer-reviewed research and preliminary findings, a few studies and reviews have stood out. We have curated this collection to offer our readers a glimpse into the current developments in health and wellness, complemented by expert commentary for those seeking further knowledge. Here are this week’s featured picks and additional reading recommendations from the latest medical updates.
Pick #1: The Egg-Cholesterol Debate
The ongoing discussion on whether egg consumption raises cholesterol levels and increases the risk of heart disease has captivated attention for years. A single large egg contains up to 186 milligrams of dietary cholesterol, as per the American Heart Association (AHA). Previously, the daily recommended cholesterol limit was 300 milligrams, sparking concerns. Current dietary guidelines, however, suggest keeping this intake “as low as possible” without compromising nutritional requirements. Despite this, a recent study revealed that outdated misconceptions about eggs persist, deterring individuals from including them in their daily diets. Experts, such as registered dietitian nutritionist Kelsey Costa, emphasize that eggs offer a rich source of protein and essential micronutrients. “Eggs are a valuable source of lean protein and key nutrients like folate, vitamin A, B vitamins, phosphorus, and selenium,” Costa shared with Medical News Today. She also highlighted that the production and preparation of eggs can influence their potential benefits or drawbacks.
When did the guidelines shift?
The recommendation to restrict egg consumption and monitor cholesterol levels was initially advocated by the AHA in 1968. The conversation gained renewed attention in 2015 when the Dietary Guidelines for Americans (DGA) eliminated the daily egg consumption limit due to cholesterol concerns. Donna Kritz-Silverstein, PhD, noted, “Previously, there was a belief that dietary cholesterol, particularly in eggs, could elevate plasma cholesterol levels. Subsequent research led to a reduction in the permissible dietary cholesterol intake for individuals at high risk of heart disease. It wasn’t until 2015, following extensive research, that these guidelines were revised.”

Evaluating cholesterol levels and glaucoma risk, experts like Yu-Ming Ni, MD, suggest a potential link between “good” HDL-C and lower glaucoma rates, and “bad” LDL-C and higher glaucoma rates. If you’re wondering why doctors refer to cholesterol as good or bad, read on.
Shifting focus to GLP-1 drugs, commonly associated with weight loss despite being primarily for type 2 diabetes treatment, ongoing research explores their broader health impacts. Recent evidence highlights concerning effects on eye health, including vision problems like NAION. Should this be a cause for concern?
Further investigations show that certain GLP-1 medications could potentially lead to eye complications like nonarteritic anterior ischemic optic neuropathy. As usage of these drugs increases, monitoring for adverse effects on the eyes and other body parts becomes crucial.
On a positive note, recent studies also suggest a connection between GLP-1 medications and reduced COPD symptoms in individuals with type 2 diabetes. Such findings provide valuable insights for managing chronic conditions effectively.
In the realm of heart health, ketone supplements have gained popularity alongside the ketogenic diet. Research indicates a potential improvement in heart function after consuming ketone drinks, particularly in older adults with type 2 diabetes. Exploring further into the dose-response relationship of ketones and heart function could offer valuable insights for healthy individuals.
While the study’s findings on ketone supplements may seem promising, it’s essential to remember that they were specific to a small group of participants. Exploring the potential benefits of the keto diet in treating autoimmune diseases adds another layer to its versatility beyond its initial recommendation for epilepsy.
