Vitamin K2: A Silent Guardian of Heart Health?

Dr. Kumar’s Take:

Vitamin K2 doesn’t get much attention, but it plays a crucial role in protecting your heart and blood vessels. It activates proteins that stop calcium from building up in places it doesn’t belong—like your arteries and heart valves. This review highlights how low vitamin K2 levels are linked to stiffer arteries, more calcified heart valves, and a higher risk of heart failure and death. If you’re over 40, have kidney disease, or take a statin, you may especially benefit from paying attention to your vitamin K2 intake.

Vitamin K2 May Help Protect Against Heart Disease, Study Finds

Dr. Kumar’s Take:

This large study from the Netherlands found that people who ate more vitamin K2 (menaquinone)—mostly from fermented foods like cheese—had fewer heart attacks, lower risk of dying from heart disease, and less calcium buildup in their arteries. Interestingly, vitamin K1, which comes from leafy greens, didn’t show the same benefits. This tells us that vitamin K2 may play a special role in keeping our blood vessels healthy and flexible.

Walking Faster, Living Longer: Why Physical Activity Matters More for Men With Diabetes

Dr. Kumar’s Take:

This long-term study gives us something very simple and powerful: just walking faster or being a little more active in your free time could lower your risk of dying from heart disease—especially if you have type 2 diabetes or prediabetes. The more physically active you are, the better your chances of living longer and healthier. If you’re managing diabetes, building in physical activity isn’t just good advice—it might be life-saving.

Trans Fats and Heart Disease: What a Massive Harvard Study Found

Dr. Kumar’s Take:

This large study of over 85,000 women provides strong evidence that eating more trans fats—like those found in margarine, cookies, and processed foods—raises the risk of heart disease. Even after accounting for other factors like smoking, exercise, and cholesterol, the link remained strong. Not all fats are equal. This study reinforces that trans fats are some of the most harmful. Aim to cut them out wherever possible.

Vitamin K2 and Heart Health: A Promising Ally Against Artery Calcification

Dr. Kumar’s Take:

Most people don’t think about vitamin K2 when it comes to heart health—but this review shows we probably should. Vitamin K2 helps activate a special protein called matrix Gla protein (MGP), which stops calcium from building up in your arteries and heart valves. When you don’t get enough vitamin K2, this protein stays inactive, and your risk of artery hardening, heart valve disease, and even heart failure goes up.

Can One Simple Blood Test Predict Your Heart and Metabolic Health?

Dr. Kumar’s Take:

Many people believe that lowering their LDL cholesterol is enough to protect their heart—but this study tells a deeper story. Researchers found that the triglyceride to HDL cholesterol ratio (TG/HDL-C) is a powerful marker for heart disease, stroke, and metabolic syndrome, even when LDL is under control. This simple blood test could help catch risk earlier and personalize prevention.

Actionable Tip: Ask your doctor about your TG/HDL ratio next time you get blood work. A higher number may mean higher risk—even if everything else looks “normal.”

Meditation and Cardiovascular Health: A Scientific Statement

Dr. Kumar’s Take:

This study shows that meditation might be a simple, low-cost way to help improve your heart health. The research found that people who meditate tend to have lower risks of problems like high cholesterol, high blood pressure, diabetes, stroke, and heart disease. Adding a meditation practice to your daily routine could be a useful part of a healthy lifestyle when paired with good nutrition and regular exercise.

Do Plant Sterols Really Help Your Heart? A Closer Look at the Evidence

Dr. Kumar’s Take:

Plant sterols and stanols are natural compounds found in certain foods that can lower LDL cholesterol by about 10% when taken at recommended doses. While this sounds promising, there is no strong evidence that they actually reduce the risk of heart attacks or strokes. Some recent genetic studies even suggest that in certain people, high levels of plant sterols in the blood could increase heart disease risk. If you’re generally healthy and not on medication, sterol-fortified foods might help bring your LDL down. But if you’re at high risk for heart disease, it’s best to talk to your doctor before supplementing with plant sterols.

Aspirin for Heart Health: Does It Really Help?

Dr. Kumar’s Take:

Aspirin has long been promoted as a heart health booster, but does it truly prevent heart disease? A meta-analysis of nine major studies explored this question. The findings? Aspirin reduces the risk of heart attacks and certain strokes but does not lower overall heart-related death rates. Even more concerning, aspirin use increases the risk of serious bleeding, including hemorrhagic stroke and gastrointestinal bleeding.

What You Can Do:

✔ If you’re at high risk for heart disease, talk to your doctor about aspirin. The benefits might outweigh the risks.

Apolipoprotein B: A Better Predictor of Heart Disease Risk Than LDL Cholesterol?

Dr. Kumar’s Take:

A study published in the Journal of the American College of Cardiology found that apolipoprotein B (apoB) and non-HDL cholesterol are better markers of cardiovascular risk than LDL cholesterol in patients taking statins. If you’re on cholesterol-lowering medication, relying solely on LDL cholesterol may not give you the full picture of your heart health. Instead, measuring apoB could provide a clearer assessment of your risk for heart disease.

Mediterranean Diet and Heart Health: How Much Does It Really Help?

Dr. Kumar’s Take:

The Mediterranean Diet has long been praised for its heart-protective benefits, but how much does it actually reduce the risk of heart disease? A recent systematic review examined both primary prevention (for people without heart disease) and secondary prevention (for those with existing cardiovascular disease, CVD). The findings suggest that the Mediterranean Diet significantly lowers the risk of heart-related deaths and major cardiovascular events. However, the way risk reduction is reported—absolute vs. relative risk reduction—can be misleading. Let’s break it down so you can understand what it really means for your health.

Mediterranean Diet vs. Low-Fat Diet: Which One Protects Your Heart Better?

Dr. Kumar’s Take:

The CORDIOPREV study is one of the most comprehensive long-term studies examining whether a Mediterranean diet rich in extra-virgin olive oil or a low-fat diet is better at preventing heart disease recurrence. After 7 years of follow-up, the results were clear: the Mediterranean diet significantly reduced cardiovascular events compared to the low-fat diet.

For patients with coronary heart disease (CHD), these findings are game-changing. They suggest that switching to a Mediterranean diet could reduce the risk of future heart attacks, strokes, and other cardiovascular events—without strict fat restrictions.
