If someone has had a heart attack once, it becomes necessary to take a proper diet to avoid another heart attack. Cardiologists say that our diet affects body weight, blood pressure, cholesterol level, and blood sugar level. If someone has had a heart attack or has been treated for cardiovascular disease before, then changes in diet can prevent the disease from worsening and another heart attack.

Heart patients have many diet options to improve their health. Heart patients should have vegetables and fruits on their plate. Along with this, whole grains and healthy proteins should also be eaten along with them.

Monounsaturated fats and omega-3 fatty acids are considered very good for the heart. Eat plenty of monounsaturated fats like avocado, olive oil and almonds. Consumption of all these things reduces bad cholesterol and increases good cholesterol. This keeps the heart healthy.

Whole grains, fruits and vegetables are rich in fiber. Whole grains like brown rice and quinoa control blood sugar levels and cholesterol in the body. Fruits and vegetables also contain vitamins, minerals and antioxidants, which keep our heart healthy. Broccoli, carrots, and leafy vegetables are good for the heart.

Dairy products rich in calcium, protein and vitamins help prevent heart diseases. Low-fat or fat-free dairy products are better than high-fat ones. These include fat-free yogurt, cheese and milk.

Heart patients should consume less salt. Salt is good for the body if taken in small amounts, but excess salt can increase blood pressure. Therefore, consume salt in small amounts. Use herbs and spices instead of salt.
