When it comes to diet trends, it can be hard to know which ones truly benefit your heart and which may do more harm than good. Professor Jason Kovacic, a leading cardiologist and Institute Director, recently shared his expert ranking of popular diets—from the best choices to the worst offenders for long-term heart health.
Mediterranean Wins, Carnivore Fails
In his breakdown, Professor Kovacic rated the Mediterranean diet a perfect 10/10, calling it the gold standard for cardiovascular health. Rich in vegetables, fruits, olive oil, fish, whole grains, and nuts, this diet supports balanced nutrition, lowers cholesterol, and reduces inflammation.
On the other end of the spectrum, he gave the carnivore diet just 1/10. The reason? Eliminating fruits, vegetables, and fibre-rich foods places heavy stress on the heart, increases cholesterol, and deprives the body of essential nutrients. He cautioned that extreme, restrictive diets are rarely sustainable and often harmful in the long run.
Other Diet Habits in Focus
Professor Kovacic also addressed some popular misconceptions. For instance, while red wine is often praised for being “heart-friendly,” he only gave it 2–3/10, warning that alcohol’s risks outweigh its benefits when consumed regularly. Similarly, fad diets promising fast weight loss but relying on processed or unbalanced eating patterns were deemed damaging.
His advice was clear: “Your heart needs balance, variety, and sustainability—not just one macronutrient on repeat.”
Building Heart-Healthy Habits
Fortunately, supporting heart health doesn’t mean settling for boring meals. The cardiologist recommends:
- Following a Mediterranean-style diet packed with colourful vegetables, lean proteins, olive oil, and nuts.
- Avoiding processed foods, excess sugar, and trans fats.
- Limiting alcohol consumption.
- Focusing on moderation rather than cutting out entire food groups.
- Pairing good nutrition with regular exercise, quality sleep, and stress control.
The Verdict
Fad diets will always come and go, but your heart needs consistent care. The takeaway from Professor Kovacic’s verdict is simple: Mediterranean-style eating supports a longer, healthier life, while extreme diets like carnivore put your heart at risk.
