Cholesterol is a waxy substance found in your blood. Your body needs cholesterol to build healthy cells, hormones, however high levels of cholesterol can increase your risk of heart disease. With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke. A healthy diet, regular exercise and sometimes medication can help reduce high cholesterol.
Berries are an integral part of the human diet, both as fresh and frozen berries which may act as useful food. They also have a pleasant taste and little calorific content. In addition, berries and have high concentrations of phenolic compounds: flavonoids such as anthocyanins, and non-flavonoids such as stilbenes and phenolic acids, which can decrease cardiovascular risk. As berries are very often consumed raw, these compounds are not deactivated by cooking.
Berries, such as blackberries, blackcurrants, raspberries, bilberries or blueberries, cranberries, lingonberries, and strawberries have been shown to decrease in LDL oxidation (and therefore reduce LDL build-up) and increase and an increase in HDL-cholesterol following dietary intervention
Anthocyanins cause the blue, purple and red colour of many fruits, including berries and are found at the highest concentrations in the skins of berries.
Studies show that antioxidants might block or slow the build-up of cholesterol in the arteries of people who are at higher risk of heart disease.
In addition, specific berries, such as bilberry and black currant extracts, cranberry extracts, and freeze-dried strawberries were shown to have favourable effects on plasma glucose or lipid profiles in people with risk factors including type 1 or type 2 diabetes mellitus, dyslipidaemia or metabolic syndrome.
As always you should do, with any herbal or dietary supplement, talk to your doctor if you use concentrated fruit extracts regularly as a supplement.
Metabolic syndrome: is a cluster of conditions that occur together, increasing your risk of heart disease, stroke and type 2 diabetes. These conditions include increased blood pressure, high blood sugar, excess body fat around the waist and abnormal cholesterol or triglyceride levels.
Dyslipidaemia: is an abnormal amount of lipids (e.g. triglycerides, cholesterol and/or fat phospholipids) in the blood. In developed countries, most dyslipidaemias are hyperlipidaemias; that is, an elevation of lipids in the blood. This is often due to diet and lifestyle.

Try to limit the saturated fats: Eating a diet rich in saturated fats can elevate levels of ‘bad’ cholesterol, which may increase the risk of heart and circulatory complications. Trying to limit saturated fats found in butter, lard, ghee, cheese and fatty meats can be helpful. It is important to remember that for example butter is rich in nutrients and beneficial compounds like butyrate and conjugated linoleic acid. High-fat dairy products like butter have been linked to a reduced risk of obesity, diabetes, and heart problems.
Some circulation-friendly foods:
· Oily fish: mackerel, sardines, herring, cold water line caught wild salmon.
· Citrus fruit
· Cayenne pepper
· Onions and garlic
