Mediterranean diet voted best in the world — but a dietitian recommends this tweaked diet instead. Here's why

Here's what you need to know about the best-ranked diets in the world.

Welcome to Ask A Dietitian, a series where Yahoo Canada digs into food trends and popular nutrition questions with registered dietitian Abbey Sharp.

As health-conscious individuals seek the best dietary choices for optimal well-being, the Mediterranean diet has once again claimed the top spot in the annual rankings by US News.

According to the latest report, the Mediterranean diet secured the number one position for the seventh consecutive year, with an impressive score of 85 per cent. This recognition comes after experts assessed diet plans for nutritional values, health risks and benefits, long-term sustainability and effectiveness.

This diet is based on primarily plant-based foods and healthy fats from seafood and olive oil. It also promotes whole grains, legumes and some lean poultry. It's a "top-rated diet for those looking for a heart-healthy diet, a diabetes-friendly diet or to promote bone and joint health," US News reported.

The second best diet was the "heart-healthy" DASH diet, aimed to stop or prevent high blood pressure, rated at 75 per cent overall.

In light of this new and ongoing acknowledgment, Yahoo Canada revisited its conversation with registered dietitian Abbey Sharp, who shared valuable insights on why these diets — or better yet, a combination of both — is recommended for healthy aging.

Here's what you need to know.


Researchers recommend the MIND diet. What is it?

Canadian dietitian Sharp said one of the best diets as we age is the MIND diet — a combination of the Mediterranean diet and the DASH diet (a whole foods diet limiting sodium intake).

"Research suggests that folks with the highest mind diet scores had significantly lower rates of cognitive decline, to those who have the lowest score," Sharp explained.

The MIND diet approach emphasizes:

  • high-fibre

  • antioxidant-rich fruits and vegetables

  • whole grains

  • lean proteins (especially plant-based)

  • essential fats like omega-3s

  • mono-unsaturated fats

While there's no magic "superfood," incorporating nutrient-dense options can enhance your diet.

Lean proteins like fish and some poultry, and plant-based proteins like beans and legumes, are important for supporting muscle maintenance and preventing muscle loss. They also provide B12 vitamin which we absorb less of as we age.

Greek yogurt is another "calcium and protein powerhouse," aiding in maintaining bone and muscle mass.

Berries, with their antioxidant-rich profile, are linked to reduced cognitive decline and a lower risk of dementia. Healthy mono-unsaturated fats found in foods like fish or olive oil are important for heart health.

The MIND diet also recommends limit highly processed high sugar foods, such as pastries, fried foods, red meat and added fats, like butter and margarine.


How mindful should I be of sugar and salt consumption?

Sharp said the current recommendation around salt intake is no more than 2,300 milligrams of sodium a day, and no more than 10 per cent of calorie intake from sugars daily.

The MIND diet suggests restricting sweets and pastries to four servings per week.

But Sharp advises to be mindful of hidden sodium in processed foods. "A lot of people don't realize that sodium is not just what what you put on your meal at the table. We really want to focus on a lot of the ultra-processed foods."

This means opting for fresh herbs, lower sodium seasonings and reducing reliance on convenience and fast foods.


Can food help boost my immune system?

While you can't "boost" your immune system through diet alone, a nutrient-rich diet can support it, Sharp claimed.

Key nutrients, largely found in plant-based foods, contribute to the growth and function of immune cells, including: iron, vitamins A, C, D, E and zinc.

Lots of colorful foods like fruits and vegetables, nuts, beans, legumes, some greens, fatty fish — that's really what we want to be focusing on.

Those antioxidants work by neutralizing free radicals, which can help to contribute to chronic disease, the dietitian explained.


How can I transition to a healthier diet later in life?

For those looking to transition to a healthier diet, the key is to take gradual steps.

"They always say 'it's hard to teach an old dog new tricks.'... The last thing you need is to jump in too hard, too fast, and then just immediately throw in the towel," Sharp claimed.

Start with small changes, like eating one meatless meal a week. Other baby steps can include:

  • slowly cutting back on on red meat and eating more poultry or fish

  • serving fruit with your cookies at snack

  • swapping white bread for whole grain

  • mixing whole grain high-fiber cereal into your refined usual choice

  • choosing nuts instead of chips

"Just making those tiny little tweaks over time and seeing how they feel, and then going from there and kind of building as you go," Sharp said.
