Making lifestyle changes is a very effective way of preventing as well as reducing your risk of developing a cardiovascular disease, such as a coronary heart disease, heart attack or stroke.
There are five ways that can help you reduce your risk of developing heart disease:
- stop smoking (if you smoke)
- eat a healthy diet
- take regular exercise
- lose weight (if you are overweight or obese)
- moderate your consumption of alcohol
If you smoke, it is strongly recommended that you quit as soon as possible. It is recommended that you eat two to four portions of oily fish a week. Oily fish contains a type of fatty acid called omega-3. Omega-3 can help lower your cholesterol levels. It is also recommended that you eat more fruit, vegetables and fish, and less meat. Replace butter and cheese with products that are vegetable and plant-oil based, such as olive oil.
If you are overweight, or obese, you should lose weight, and maintain a healthy weight by using a combination of regular exercise and a calorie-controlled diet. Remember that alcohol can raise your blood pressure and your cholesterol level, which will increase your risk of developing CVD. A minimum of 30 minutes of exercise a day five times a week is the recommended. Activities may include: brisk walking, running, cycling and swimming.

BLOOD
Blood is a mixture of two components: cells and plasma. The heart pumps blood through the arteries, capillaries and veins to provide oxygen and nutrients to every cell of the body. The blood also carries away waste products.
The adult human body contains approximately 5 liters of blood; it makes up 7 to 8 percent of a person's body weight. Approximately 2.75 to 3 liters of blood is plasma and the rest is the cellular portion.

Plasma is the liquid portion of the blood. Blood cells like red blood cells float in the plasma. Also dissolved in plasma are electrolytes, nutrients and vitamins (absorbed from the intestines or produced by the body), hormones, clotting factors, and proteins such as albumin and immunoglobulins (antibodies to fight infection). Plasma distributes the substances it contains as it circulates throughout the body.
The cellular portion of blood contains red blood cells (RBCs, erythrocytes), white blood cells (WBCs, leucocytes) and platelets (thrombocytes). There are 4,5 to 5 million erythrocytes, from 4,500 to 9,500 leucocytes and from 200,000 to 400,000 platelets in each cubic millimetre of blood. The RBCs carry oxygen from the lungs; the WBCs help to fight infection; and platelets are parts of cells that the body uses for clotting.
All blood cells are produced in the bone marrow. Bone marrow that actively produces blood cells is called red marrow, and bone marrow that no longer produces blood cells is called yellow marrow.
Human blood is divided into four groups: group AB, group A, group B, group 0.
