Want to live longer? These 3 foods are linked to better heart health and lower disease risk, studies show |
Diet plays a crucial role in determining long-term health and lifespan. Global research has consistently shown that certain foods contain powerful nutrients that can protect against chronic diseases and support longevity. Among these, whole grains, nuts, and fresh fruits and vegetables have received the strongest scientific backing. They not only provide essential vitamins, minerals, and antioxidants but also help regulate cholesterol, blood pressure, and inflammation, all key factors linked to ageing and disease.Over the years, multiple large-scale studies involving hundreds of thousands of participants have confirmed that regular consumption of these foods is strongly associated with a lower risk of heart disease, type 2 diabetes, and premature death. Here’s a detailed look at how each of these three food groups supports long-term health and what science says about their impact on longevity.
3 everyday foods that can help you live longer, according to science
Whole Grains: The foundation of a healthy heart
- What they are: Whole grains include foods like oats, brown rice, barley, millets, quinoa, and whole wheat. Unlike refined grains, they retain all parts of the grain, the bran, germ, and endosperm, which makes them richer in nutrients and fibre.
- Scientific findings: Meta-analyses of cohort studies involving over a million people have shown that individuals who regularly consume whole grains have a significantly lower risk of cardiovascular disease and total mortality. A 2016 review published in BMJ and later systematic analyses confirmed that consuming about 90 grams of whole grains per day could reduce the risk of heart disease by up to 20%.
- Mechanisms: Whole grains are packed with dietary fibre, B vitamins, magnesium, and plant compounds that promote healthy digestion and metabolism. The fibre content helps control cholesterol and blood sugar levels, while antioxidants reduce inflammation in the arteries. Together, these mechanisms improve heart function and support long-term cardiovascular health.
- How to include them: Replacing refined carbohydrates like white rice or white bread with brown rice, oats, or whole-wheat chapatis is a simple way to increase whole-grain intake. Even small, consistent changes over time can have a measurable effect on overall health.

Nuts: Tiny nutrient powerhouses that protect the heart
- What they are: Nuts such as almonds, walnuts, pistachios, and cashews are energy-dense foods containing healthy fats, proteins, and essential micronutrients.
- Scientific findings: Research published in BMC Medicine and other peer-reviewed journals has found that eating a small handful of nuts daily (around 28 grams) can reduce the risk of heart disease by 25% and all-cause mortality by nearly 20%. Regular nut consumption has also been linked to a lower risk of type 2 diabetes and inflammation-related conditions.
- Mechanisms: Nuts are rich in monounsaturated and polyunsaturated fats that help reduce LDL (bad cholesterol) while maintaining HDL (good cholesterol). They also contain magnesium, selenium, and antioxidants that reduce oxidative stress, one of the key factors in ageing and heart disease.
- How to include them: A handful of unsalted nuts as a snack or as a topping on salads, yoghurt, or breakfast cereals provides an easy daily boost. Studies show that even moderate intake a few times per week contributes to cardiovascular protection.
Nuts
Fruits and vegetables: Natural defenders against ageing
- What they are: Fruits and vegetables form the cornerstone of a longevity-focused diet, providing an array of vitamins, minerals, antioxidants, and fibre.
- Scientific findings: Large cohort studies, including data from over two million participants across 95 populations, show that individuals consuming five servings of fruits and vegetables daily have a 13% lower risk of death from all causes compared to those consuming less than two servings. An optimal mix of two fruits and three vegetables per day has been associated with the strongest protective effect.
- Mechanisms: Fruits and vegetables contain compounds like flavonoids, carotenoids, and polyphenols that protect cells from oxidative damage. Their potassium and fibre content also support heart health by regulating blood pressure and improving digestion. Additionally, these foods help maintain a healthy weight by providing nutrients with minimal calories.
- How to include them: Aim for at least five servings daily, preferably of different colours leafy greens, cruciferous vegetables, berries, citrus, and seasonal produce. Fresh and lightly cooked options retain the most nutrients.
Why these foods matter for longevity
Scientific consensus suggests that no single food guarantees a longer life. However, consistent dietary patterns that prioritise plant-based, minimally processed foods, such as the Mediterranean or DASH diets, have shown measurable benefits in lowering the risk of premature death. Whole grains, nuts, and fruits and vegetables are common elements across these diets. They provide nutrients that reduce inflammation, improve metabolic function, and support healthy ageing at the cellular level.Furthermore, replacing refined or processed foods with these nutrient-dense options has a cumulative positive effect. Over decades, even small dietary improvements can significantly impact longevity and quality of life.
Practical tips for everyday eating
- Start with breakfast: Choose oatmeal, whole-grain toast, or millet porridge instead of refined cereals.
- Snack smart: Replace chips or sweets with a small portion of nuts or seeds.
- Fill half your plate with plants: Include a mix of cooked and raw vegetables in every meal.
- Stay consistent: Long-term habits matter more than short-term diets.
