American Heart Association Releases New Dietary Guidance To Improve Heart Health

The American Heart Association (AHA) has shared "2026 Dietary Guidance to Improve Cardiovascular Health", which provides an updated set of rules for eating in a way that protects your heart. These guidelines emphasise that healthy eating patterns can help reduce the risk of cardiovascular diseases and related conditions. According to the AHA, cardiovascular diseases begin early in life, and the relevance of diet quality on cardiovascular health starts as early as the prenatal period. Poor dietary patterns are strongly linked to risk factors associated with cardiovascular conditions such as obesity, metabolic syndrome, hypertension, dyslipidemia, and type 2 diabetes. The guidance notes that a heart-healthy diet centres on fruits, vegetables, whole grains, plant-based proteins, and unsaturated fats, while limiting sugar, sodium, and ultraprocessed foods.

AHA has also mentioned that early and consistent adoption of healthy eating, alongside other healthy lifestyle behaviours, can help prevent up to 80% of heart disease and stroke. Here are the 9 key features of a heart-healthy diet.

9 Features of dietary patterns to support cardiovascular health

1. Balance calories with exercise

Maintaining a healthy body weight is crucial for cardiovascular health. AHA states that obesity affects 21% of children and adolescents, and 40% of adults in the United States. Energy intake should be balanced with physical activity, with guidance on appropriate activity levels for various age groups.

2. Eat lots of fruits and vegetables

Whole, minimally processed vegetables and fruits are vital for heart health, providing essential nutrients and dietary fibre. AHA mentions that if frozen or canned varieties are purchased, they should preferably not contain added sugars or sodium.

3. Choose whole grains

Whole grains contain all parts of the grain kernel and are associated with a lower risk of cardiovascular disease and better heart health markers. Shifting from refined to whole grains can improve health outcomes. Commonly consumed whole grains are whole wheat, oats, brown rice, quinoa, barley, and rye.

4. Pick healthy protein

Focus on protein sources with favourable fatty acid profiles and fibre content to promote cardiovascular health. This feature is divided into 4 subgroups:

• Shift from meat to plant sources

Incorporate legumes (beans, peas, lentils) and nuts, which are associated with lower cardiovascular disease and coronary heart disease risk. Be cautious of ultraprocessed plant-based meat alternatives.

• Regular fish and seafood consumption

Eating nonfried fish and seafood is linked to lower cardiovascular disease events and myocardial infarction risk, potentially due to omega-3 fatty acids.

• Opt for low-fat dairy products

Low-fat and fat-free dairy may be linked to lower cardiovascular disease risk, although evidence is still debated. Fermented dairy products may offer additional cardiovascular benefits.

• If consuming red meat, choose wisely

Select lean cuts, limit portion sizes, avoid processed meats, and replace red meat with healthier protein sources for better cardiovascular disease risk outcomes.

Overall, diets higher in plant proteins and lower in animal proteins are associated with improved cardiovascular health. Prioritise unsaturated fats and minimise processed meats.

5. Choose unsaturated fat over saturated fat

Studies often recommend replacing saturated fats with and, to a lesser extent, monounsaturated fats lowers low-density lipoprotein (LDL) cholesterol, a risk factor for cardiovascular disease. Nontropical plant oils like soybean, canola and olive are high in unsaturated fats and effectively reduce LDL cholesterol when used instead of animal fats and tropical oils.

6. Avoid ultra-processed foods

Focus on consuming minimally processed foods instead of ultraprocessed options, which often contain high levels of sodium, added sugars, and unhealthy additives. There is a strong link between ultraprocessed foods and adverse health outcomes like obesity, cardiovascular diseases, and type 2 diabetes.

7. Cut down on added sugars

Limit intake of added sugars, which can significantly increase the risk of obesity, type 2 diabetes, coronary heart disease, and cardiovascular mortality. High consumption of added sugars is associated with nearly three times the risk of cardiovascular disease mortality compared to lower intake.

8. Limit salt intake

High sodium intake raises blood pressure, a leading risk factor for heart failure. Reducing sodium, particularly when combined with increasing potassium intake, can lower blood pressure and reduce cardiovascular disease risk.

9. Limit alcohol

The relationship between alcohol intake and cardiovascular disease (CVD) risk is complex and currently debated. While some studies suggested a potential protective effect of low to moderate alcohol consumption on coronary heart disease, these findings may be influenced by other socioeconomic and lifestyle factors. Recent research, including Mendelian randomisation, has challenged these findings, showing no significant link between genetic predisposition to alcohol consumption and coronary artery disease risk.

The relationship between alcohol intake and blood pressure is linear, with risks starting at the lowest intake levels. The 2025 American Heart Association/American College of Cardiology guidelines recommend avoiding alcohol for managing and preventing high blood pressure. The US Department of Health and Human Services and the World Health Organisation also advise against alcohol consumption to lower cancer risks.

Initiating alcohol consumption to improve cardiovascular health is not recommended due to uncertainties about its overall health effects and potential harm to other health outcomes.

While these measures can help boost heart health and reduce the risk of cardiovascular diseases significantly, heart-healthy dietary patterns are also rich in vitamins, essential minerals, and other health-promoting components. They can help individuals meet their nutritional requirements, promoting overall health.
