Best Diets for Heart Health
The heart is a vital organ in the human body. Therefore, the heart needs utmost care and protection. According to the world health organisation (WHO), 17.9 million people died globally due to heart diseases in 2019. The number has only increased from that time onwards. This number represents 32% of global deaths in the year 2019. These days, with a sedentary lifestyle and junk and fast food consumption increasing, the most damage is happening to the heart. Wondering why? This article answers the question.
How does the Heart Function?
You must have heard that the heart supplies blood to the whole body. But this is not its function in totality. The heart’s primary function is to supply oxygen to the other body organs. It also removes the deoxygenated blood from the organs and gives it to the lungs. Then, it goes to the heart from the lungs. From here, the oxygenated blood goes to the whole body.
The heart works with the system known as the circulatory system in the human body. The arteries, veins, blood vessels, and blood make up the circulatory system. The heart is in the chest, between the lungs. It tilts slightly towards the left of the human body. In addition, the arteries supply the oxygenated blood to the organs from the heart. The veins take away the deoxygenated blood from the organs. Then return it to the lungs for reoxygenation. This cycle goes on throughout the process of life.
Diets for Heart Health
Knowing the correct balance between the nutrients and food you eat is the key to good heart health. A balanced diet is the optimum and the most reliable diet you can follow for good health.
This diet contains 40-60% carbs, 15-20% protein and rest from fat of the energy from complex carbohydrate sources. In addition, 10-13% comes from good protein sources, and the rest comes from good fat.
- Carbohydrates: From whole grains and pulses such as whole wheat, millets, oats etc. Replace refined flour with whole grain flours for rotis and breads.
- Protein: From animal sources which are of good quality such as eggs, lean meats, dairy along with plant sources such as pulses and legumes.
- Fats: From good sources like nuts, oilseeds, fatty fish. Some examples are tuna, salmon, mackerel etc.
- Vitamins and minerals: From fruits and vegetables of all colours
These will also give you fibre and will keep your heart healthy.
DASH [Dietary Approaches to Stop Hypertension] Diet
This diet is a result of research over the years, and it’s proven to be effective against hypertension and heart diseases. Per serving in the DASH diet is 30 grams. The guide to this diet is as follows:
- Vegetables: 5 servings per day
- Fruits: 5 servings per day
- Carbs: 7 servings per day
- Low-Fat Dairy: 2 servings per day
- Lean Meat Products: 1-2 servings per day
- Nuts and Seeds: 20-30 grams per week.
Healthy Food Sources that You can Add:
- Green leafy vegetables like spinach, amaranth etc.
- Complex carbohydrates like split wheat, cracked wheat, rolled oats, Ragi, Jowar, Bajra etc.
- Pulses, legumes and beans
- Low glycemic index fruits
Healthy Fats that You can Add:
- Olive oil
- Tuna and salmon fish
- Nuts like almond and pistachios
- Flaxseeds and hemp seeds
Protein Sources that You can Add:
- Low-fat dairy
This diet helps you meet the dietary recommendations of a healthy heart.
- Focus more on fruits, vegetables, whole grains, beans, and legumes;
- Dairy products with low or no fat, fish, poultry, non-tropical vegetable oils, and nuts; and
- You should avoid carbonated beverages, highly processed foods, refined carbs, saturated fats, and fatty or processed meats.
Obesity, diabetes, high cholesterol, and high blood pressure are risk factors for heart disease and stroke. However, this way of eating can help prevent them. For example, a Mediterranean diet high in virgin olive oil may help the body remove extra cholesterol from arteries and prevent coagulation in blood vessels.
Vegetarian and Vegan Diet
Research has proven that plant-based diets like vegan and vegetarianism improve heart health. This diet can include the following:-
- Carbohydrates from complex sources like whole grains, cereals and millets
- Protein from pulses, nuts, plant-based milk etc
- Vitamins and minerals from fruits and vegetables
- Good fat from nuts and oilseeds
- Dairy from milk and milk products (only in case of vegetarians)
This diet reduces cholesterol and improves heart health.
As the name says, this diet includes food items rich in antioxidants. Inflammation due to stress, lifestyle, pollution is the primary cause of bad heart health. To make the heart-healthy, you have to consume foods rich in antioxidants. Antioxidants reduce inflammation in the body. As they lower free radicals, causing inflammation. After binding, the free radicals stop the damage in the body. Hence, it helps reduce inflammation and maintains a healthy heart. Food items rich which need to be in this diet are as follows:-
- Bell peppers
- Citrus fruits
- Red kidney beans
- Red cabbage
- Whole grains
- Dark green leafy vegetables
The diets mentioned above are specific. With the difference in culture, region, season, these particular diets may be difficult to follow. A balanced diet is more manageable than following a specific diet to ease this process. Please incorporate the following food items into the diet to follow a balanced diet.
These are whole grains and millets. You must be thinking what’s the difference between complex carbohydrates and regular carbohydrates. Let’s solve the mystery today. Regular carbohydrates are refined carbohydrates. These are well polished and devoid of their husk or skin, the outer layer. Many vitamins, minerals, antioxidants, and beta-glucans get removed from the grain in removing the husk. And we are left with nothing but simply calories- For example, maida or refined wheat flour.
A range of tasty and unhealthy food items like cakes, pastries, muffins, puff pastry, kachori, paratha etc., are made using refined flour. Research establishes the relationship between the consumption of refined carbohydrates and the increasing risk of cardiovascular diseases.
On the other hand, complex carbohydrates come along with their husk. It means they go through the grinding process to turn into a fine powder and the outer layer. Therefore, the nutritional value shoots up, and it’s rich in vitamins, minerals and many other nutrients.
The various phenolic acids, phytoestrogens, vitamins and minerals in the complex carbohydrates reduce inflammation, reducing plaque formation. Reduced plaque formation in the heart’s arteries leads to a healthy heart. Therefore, this is how complex carbohydrates lead to a healthy heart. Some sources of complex carbohydrates are:-
- Millet flour-like Jowar, Bajra, Ragi
- Whole wheat flour with millet flour
- Broken wheat or Dalia
These are high biological value protein sources like egg, chicken and fish—these supply all the essential amino acids to the body. Amino acids are the building blocks of your body. They help build strong muscles and provide strength to the body for regular functioning. One should remember that red meat is harmful to the heart. Incidentally, red meat increases cholesterol levels, harming the heart. While on the other hand, white meat is lean; this supplies adequate protein to the body without harmful fat. As a result, it keeps the heart-healthy.
The process of cooking chicken and fish is essential. Pan-frying, baking, stewing are much better methods than roasting or grilling. Roasting and grilling foods may have carcinogenic traces in them. Therefore, avoid such foods and have them only during special occasions.
Yes, you read it right; fats are healthy. Fats have a wide range of classifications. This classification includes saturated fats and unsaturated fats. Saturated fats are harmful to the heart and the body as they increase cholesterol levels, detrimental to good heart health. On the other hand, Unsaturated fats are much more healthy and more beneficial for the heart.
- Omega 3 & 6 fatty acids
- Polyunsaturated Fatty Acids (PUFA)
- Monounsaturated Fatty Acids(MUFA)
The sources of these fatty acids are below:-
- Fatty fish like tuna, salmon, mackerel
- Nuts like cashews, almonds, walnuts
- Seeds like flax seeds, sunflower seeds, safflower seeds etc
- Oil from plant sources like olive oil, rice bran oil etc.
Best Foods for Optimum Heart Health
Berries (especially strawberries and blueberries) are loaded with antioxidants and have a range of health benefits. One of which includes reducing hypertension and thus improving cardiovascular health. Berries have anthocyanin, which is a flavonoid. This flavonoid has vasodilatory properties.

It is a very famous complex carbohydrate and a go-to source for people who want to lose weight. However, the fascinating attribute of oats is that it helps improve heart health and reduce high blood pressure. In addition, oats have high amounts of fibre present, aiding in early satiety. Oats contain a unique type of fibre called beta-glucan, which is soluble. This type of fibre reduces cholesterol and plaque formation in the blood vessels.
When plaque formation reduces, it is easier to pass through the minute blood vessels. Likewise, blood pressure is normal when blood passes easily through the minute capillaries (tiny blood vessels). Therefore, this is how oats help in improving heart health.
The benefits of oats are as follows:
- Helps in weight loss
- Aids in proper digestion

Fatty fish like tuna, mackerel, sardines etc., have good fat. They are unsaturated fat ( omega3 fatty acids, polyunsaturated fatty acids and monounsaturated fatty acids). These fats are anti-inflammatory. They prevent plaque formation and coagulation in the heart’s arteries and maintain a healthy heart. These fats are beneficial because they speed up the metabolism rate in the body. Furthermore, the fibre in these fish varieties helps provide early satiety, aiding in weight loss.
Fatty fish is very nutritious. It has a high biological value protein, quickly metabolised in the body. Besides the good fat and protein, fatty fish contains minerals like selenium, magnesium etc. and fat-soluble vitamins including vitamin A, D, E and K.
Research shows that consuming fatty fish helps maintain a healthy heart with a good cognitive function and helps regulate blood glucose levels.
Some of the best ways to consume fish are:

Factors that Negatively Affect Heart Health
- Salt: The best practice is to avoid table salt altogether. However, you can use a bit of salt during cooking. But, you should refrain from eating salted nuts, biscuits, snacks etc. These foods have high amounts of salt sprinkled on top, leading to increased sodium in the body, alleviating blood pressure, and affecting heart health.
- Caffeine induces adrenaline secretion in your body, which increases blood pressure by reducing the width of blood vessels. The anti-diuretic hormone gets blocked by adrenaline. When this hormone is blocked, the blood vessels’ width reduces, resulting in high blood pressure and damaging heart health.
- Alcohol consumption binds calcium to blood vessels. When calcium binds with the blood vessels, blood cannot pass easily through the vessels. Hence, it increases blood pressure, which harms the heart.
- Junk food and fast foods are high in saturated fat, increasing cholesterol levels. Therefore, this, in turn, affects the heart in the wrong way. Hence, it is best to avoid them.
- Irregular sleep leads to lowering the metabolism, which increases weight. Increased weight leads to obesity which in turn is harmful to the heart. So follow a proper and sound sleep cycle.
- A sedentary lifestyle without exercise leads to obesity, which harms the heart. Therefore, follow an active lifestyle to keep your heart healthy.
- Stress is terrible for the heart. It is one of the significant causes of a heart attack. You should not overthink and stress about things. Being positive and exercising helps in reducing stress.
