Boost your intake of foods that contain Omega-3 fatty acids. Omega-3s are a healthy type of polyunsaturated fat. Omega-3 fatty acids offer protection from heart disease and can be found in foods such as salmon, mackerel, flaxseed, and walnuts and certain vitamin and mineral supplements.^{[2]XTrustworthy SourceHarvard Medical SchoolHarvard Medical School's Educational Site for the PublicGo to source}
- Try to incorporate wild-caught fish into your diet twice per week (farmed fish are often not as high in Omega 3's).^{[3]XResearch source}
- The only studies about using omega-3s to prevent heart disease have been done in small, select groups so more research needs to be done.^{[4]XTrustworthy SourceUniversity of Rochester Medical CenterLeading academic medical center in the U.S. focused on clinical care and researchGo to source}

Opt for whole grains and cut back on carbs. They are an excellent source of fiber and contain several healthy nutrients that can help regulate blood pressure and improve overall heart health. Though whole grains are much better than refined grains, a diet that is low in carbohydrates been shown to improve cardiovascular health.^{[7]XResearch source}
- Replace refined grain products with whole-grain products.
- Choose whole-wheat flours, 100% whole grain bread, high-fiber cereal, whole grain pasta, steel-cut oats, brown rice, and barley.
- Stay away from white or refined flours, white bread, frozen waffles, biscuits, cornbread, egg noodles, granola bars, high-fat snacks, quick breads, cakes, pies, donuts, and buttered popcorn.
- Choose complex carbs that have greater than 5 g of fiber to stay healthy.

Keep your portion sizes under control. Although what you eat is important for heart health, how much you eat is also a factor in improving overall heart health.^{[8]XExpert SourceShervin Eshaghian, MD
Board Certified CardiologistExpert Interview. 26 June 2020.} Refrain from overeating, which can lead to excess fat, cholesterol, and calorie intake.^{[9]XTrustworthy SourceCleveland ClinicEducational website from one of the world's leading hospitalsGo to source} Keeping portion sizes under control is essential to healthy eating. Use measuring cups and spoons and weight scales to measure your portion sizes until you become familiar enough to recognize them by sight only. Some ways to remember appropriate portion sizes include:
- 3 oz. of lean meat is about the size of a smart phone.
- ¼ cup of nuts is about the size of a golf ball.
- 1 cup of vegetables is about the size of a baseball.

Getting Help from Your Doctor

1
Request regular health screening tests from your doctor. Keeping tabs on your blood pressure, cholesterol levels, and blood sugar can help to keep you in good health. Blood pressure, cholesterol, and blood sugar are major factors in the development of heart disease, but you can keep them under control by having them checked often.^{[19]XTrustworthy SourceAmerican Heart AssociationLeading nonprofit that funds medical research and public educationGo to source}
- Blood Pressure. Have your blood pressure checked every two years. You may need to get checked more often if your numbers are high or if you are at risk of high blood pressure. Your blood pressure should stay below 130/80.^{[20]XTrustworthy SourceAmerican Heart AssociationLeading nonprofit that funds medical research and public educationGo to source}
- Cholesterol. The information about cholesterol has become more detailed and is based more on smaller lipoproteins than on overall cholesterol. Therefore, ask your doctor to run a cholesterol panel to check your CRP, or C-reactive protein, levels. Elevated CRP levels are linked to inflammation of the arteries, which can be linked to heart disease. A simple blood test can check your CRP levels. You may need cholesterol medication if you have LDL above 189 if you don’t have diabetes mellitus or cardiovascular disease.^{[21]XTrustworthy SourceAmerican Heart AssociationLeading nonprofit that funds medical research and public educationGo to source}
- Diabetes. The recommended age to begin screening for diabetes is 45, but you should ask your doctor when you should start having screenings based on your medical history and risk factors. Even prediabetes is now being treated by doctors as a risk factor for the development of diabetes and cardiovascular disease as well. Get screened for abnormal blood sugar levels especially if you’re between 40–70 and overweight or obese.^{[22]XTrustworthy SourceCenters for Disease Control and PreventionMain public health institute for the US, run by the Dept. of Health and Human ServicesGo to source}

Ask about metabolic syndrome. Metabolic syndrome — which refers to a cluster of risk factors that increase your risk for heart disease, stroke, and diabetes — is becoming more common as more people live a sedentary lifestyle.^{[23]XResearch source} Risk factors include excess fat around the waistline, a high triglyceride level, high blood sugar, or high blood pressure.^{[24]XTrustworthy SourceNational Heart, Lung, and Blood InstituteResearch and education center within the National Institutes of HealthGo to source}
- Combat metabolic syndrome by tackling any risk factors you may have. Exercise and change your diet to lose weight if you have abdominal obesity. Limit alcohol, manage stress, and follow other guidelines for a heart-healthy lifestyle.^{[25]XTrustworthy SourceCleveland ClinicEducational website from one of the world's leading hospitalsGo to source}

Talk to your doctor about the role of inflammation. Recent studies are showing that inflammation is a hugely overlooked risk factor for atherosclerosis. The best way to currently test for inflammation is to have your doctor check your CRP levels.^{[26]XTrustworthy SourceAmerican Heart AssociationLeading nonprofit that funds medical research and public educationGo to source}
- Inflammation may be caused by loss of muscle mass, cancer, inflammatory diseases (like rheumatoid arthritis or lupus), metabolic syndrome, and injuries to the artery wall, often caused by oxidized LDL cholesterol, smoking, high blood pressure, and high blood sugar. Make sure you have any conditions checked by your doctor before assuming your CRP levels are from heart disease.
4
Get help to quit smoking. Smoking is a major contributor to the development of heart disease and it is the leading cause of preventable deaths.^{[27]XExpert SourceShervin Eshaghian, MD
Board Certified CardiologistExpert Interview. 26 June 2020.} If you smoke, do everything that you can to quit. Ask your doctor about smoking cessation programs and medications that may help make quitting easier.^{[28]XTrustworthy SourceAmerican Heart AssociationLeading nonprofit that funds medical research and public educationGo to source}
- One study showed that smoking for two years increases one’s risk of death from cardiovascular disease by 36%.^{[29]XTrustworthy SourcePubMed CentralJournal archive from the U.S. National Institutes of HealthGo to source}
5
Talk to your doctor for advice about moderating alcohol use. Drinking alcohol in moderation may offer some benefits to your heart, but drinking too much can harm your heart health. You should have no more than one drink a day if you are a woman and no more than two drinks if you are a man. (Men over the age of 65 should only have one drink per day as well.) Any more alcohol than this can increase your risk of developing heart disease.^{[30]XTrustworthy SourceJohns Hopkins MedicineOfficial resource database of the world-leading Johns Hopkins HospitalGo to source}
- If you often struggle to stop at just one drink, discuss your options with your doctor.
If you have a history of heart disease in your family, then you should make sure that your doctor knows about it. Your doctor may recommend extra precautions to help prevent you from developing heart disease and to help you maintain good cardiovascular health.^{[31]XTrustworthy SourceAmerican Heart AssociationLeading nonprofit that funds medical research and public educationGo to source}

Tips

Many forms of heart disease can be hereditary; one could be perfectly healthy and still develop a heart condition if one's (grand)parents had it. Research your family history to see if you're likely to develop a particular heart condition.^{[32]XTrustworthy SourceCenters for Disease Control and PreventionMain public health institute for the US, run by the Dept. of Health and Human ServicesGo to source}
