Longevity after 45: 5 diets that can add up to 3 years to your life

Could changing what’s on your plate really add years to your life? A study published in the journal Science Advances, conducted on over 105,000 adults, reveals that certain diets are associated with an extended life expectancy of 1.5 to 3 years from the age of 45. Here’s what these models have in common, and how to adopt them.

Diet and longevity: what this major study reveals

The analysis involved adults aged 40 to 69 from the UK Biobank cohort. Participants with the best dietary scores lived longer. They also had less cardiovascular disease, type 2 diabetes and certain cancers.

Significantly, the researchers observed these benefits irrespective of genetic longevity profile. In other words, diet can partially compensate for less favorable genes. This discovery opens up new perspectives for all those who wish to take action on their health.

The study estimates remaining life expectancy from the age of 45. These diets target the main age-related chronic diseases. They are therefore a concrete lever for healthier aging.

“Strong adherence to certain dietary patterns is associated with an extended life expectancy of 1.5 to 3 years from the age of 45.”

What these effective diets have in common

These five models share a common foundation. They all focus on more fiber and unsaturated fats. These nutrients come from fruits, vegetables, legumes, wholegrain cereals, nuts, seeds and fish.

At the same time, these diets restrict certain foods. Ultra-processed products, red or processed meats, excess salt and sugary drinks are to be reduced. This dual approach promotes better overall health.

• More fiber and unsaturated fats
• Fewer ultra-processed foods
• Reduce red and processed meats
• Limiting excess salt
• Fewer sweet drinks

5 winning diets to extend life expectancy after age 45

The Alternative Mediterranean Diet (AMED ) adapts the Mediterranean diet to Western countries. It favors vegetables, whole grains and fish. Red meat is rare, and alcohol remains moderate.

The DASH diet was designed to combat hypertension. It focuses on fruits, vegetables, whole grains and low-fat dairy products. The main focus is on salt reduction.

The hPDI formalizes a plant-based diet. It favors whole plant foods. This model is suitable for those who wish to limit their consumption of animal products.

The DRRD aims to prevent type 2 diabetes. Its principles are similar to those of the other models. The emphasis is on foods with a low glycemic index.

The AHEI-2010 index: a global quality tool

TheAHEI-2010, developed at Harvard, serves as a global index of food quality. It evaluates all food choices. This score measures adherence to good nutritional practices.

Each of these diets has its own specific angle. Yet they all converge on similar principles. Their effectiveness depends on the quality of the foods chosen on a daily basis.

How to adopt these models after 45

After the age of 45, these diets must preserve protein and energy intakes. Age changes nutritional needs. Particular attention must be paid to maintaining muscle mass.

Medical or dietetic advice helps to adjust these models without risk. Each person has a unique profile. Adaptations allow you to enjoy the benefits without deficiencies.

The results of this study encourage us to rethink our habits. Gradually changing your diet can make all the difference. These diets offer an accessible route to a longer, healthier life.
