There are two kinds of cholesterol: High-density Lipoprotein (HDL) and Low-Density Lipoprotein (LDL). The former is considered to be good cholesterol and the latter is considered to be bad cholesterol. When someone is said to have “high cholesterol levels”, it is usually referred to high levels of LDL cholesterol in the body. Presence of HDL cholesterol in the body is considered to be healthy and helps in preventing heart disease. However, researchers are now saying that extremely high levels of HDL or good cholesterol might not be that good for the body. LDL cholesterol is considered to be bad because it has the capability of causing atherosclerosis. This is a condition which results in build-up of plaque in arteries. Plaque narrows arteries and increases risks of heart attack and stroke. Atherosclerosis can also narrow arteries in legs – a condition known as peripheral artery disease.
Extremely high levels of good cholesterol in the body can increase heart disease risks
HDL cholesterol takes LDL cholesterol away from the arteries and moves it to the liver – where it is broken down and passed from the body. Cholesterol is a precursor to steroid hormones – which perform the function of regulating body functions and bile acids. Both these functions are important for normal digestion and regulation for many cell activities.
Why excess of good cholesterol is harmful
According to the study, which was presented at the annual conference of the European Society of Cardiology (ESC Congress 2018) in Munich, Germany, people with higher than normal levels of HDL cholesterol are at risks of cardiovascular disease.
Participants of the study, who had HDL cholesterol levels above 60 mg/dl were found to be at 50% increased risk of dying from cardiovascular disease or heart attack, as compared to people whose HDL cholesterol levels were in the range of 40 to 69 mg/dl.
Average age of participants was 63. Association of high levels of HDL cholesterol was found to be more frequent among women.
The study is also indicative of the fact that it may now be time to look at cholesterol in a different way.
Following is a list of foods which can help in regulating cholesterol levels in the body:
1. Fresh fruits
3. Whole grains
5. Olive oil
12. Fatty fish
Apart from including these foods in your diet, working maintaining a healthy weight and quitting smoking can help in regulating cholesterol levels in the body.
Fruit and Vegetable Juices That Enhance the Immune System
Everyone knows that fresh fruits and vegetables are loaded with nutrients that offer a wide range of benefits for the mind and body. Certain fresh produce help enhance your immune system, making it possible for you to easily avoid various infections and diseases. Juicing the following allows you to boost your immunity in a truly refreshing and delectable way:
The sweetness of carrot juice makes it loved by kids and adults alike. Carrots get their characteristic bright orange color from its rich supply of beta carotene, a nutrient converted into vitamin A for sharper vision and better eye health. More importantly, vitamin A is an essential nutrient for a stronger immunity.
Vitamin C in lemons makes these citrus fruits excellent boosters of your immune system. Vitamin C is a well-known powerful antioxidant that protects the body from colds, cough, flu and others. Lemon juice may be acidic, but it has an alkalizing property once ingested, helping to restore optimal pH balance in the body.
Other than vitamins and minerals, apples also contain plenty of insoluble fiber. This type of carbohydrates that cannot be digested by the body works as a broom that sweeps out toxins along the intestinal tract. With all of those accumulated poisonous substances out of your body, your immunity is in top-form.
When it comes to fruits, some of the best sources of vitamin C are kiwis. Other than this super antioxidant, kiwis also contain vitamins A and E, both of which are necessary for a stronger immune system. Insoluble fiber and potassium in these fruits are also highly favorable for your cardiovascular system.
Cranberry juice is admired for its ability to bolster the urinary tract system. However, it also contains plenty of vitamin C that helps safeguard you from illnesses brought about by invading microorganisms such as bacteria and viruses.
A vegetable that makes for an excellent immune-boosting juice is broccoli, thanks to its rich supply of beta carotene and vitamin C. Every glass of broccoli juice also provides your body with sulphur, a mineral with powerful antimicrobial properties. Sulphur promotes healing as well because it detoxifies the body at a cellular level.
What makes beet juice capable of supporting the immune system is its long list of vitamins and minerals. Some of them include vitamins A and C, iron, calcium, potassium and manganese. When juicing, it’s a good idea to mix beets with other fruits and vegetables of your choice due to its strong, earthy flavor.
Reduce asthma symptoms with Omega-3
A new study has found that consuming a diet rich in omega-3 fatty acids is linked to fewer childhood asthma symptoms which are triggered by indoor air pollution.
The study published in ‘American Journal of Respiratory and Critical Care Medicine’, lays out that families and health care providers may be able to protect children from harmful effects of indoor air pollution by serving a diet rich in omega-3 fatty acids while reducing foods rich in omega-6 fatty acids such as soyabean oil and corn oil.
“Our group is working on ways to reduce the levels of indoor air pollution in Baltimore City homes,” said lead author of the study, Emily Brigham. “Results are promising, but we don’t want to stop there,” Brigham added.
The study found that for each additional gram of omega-6 intake, children had 29 per cent higher odds of being in a more severe asthma category.
Conversely, with each 0.1-gram increase in levels of omega-3 fatty acids in the diet, researchers saw 3 to 4 per cent lower odds of daytime asthma symptoms.
Indoor air pollution, from sources including cooking, cleaning activities and cigarette smoke, is a known trigger for asthma symptoms.
Omega-3 fatty acids, which are found abundantly in fish and certain nuts and seeds, are considered healthy as they are known to reduce inflammation.
Omega-6 fatty acids, primarily found in vegetable oils (including corn, soybean, safflower, and sunflower), as came out in other studies, have mixed effects on health, but have the potential to promote inflammation.
The researchers, however, noted that it doesn’t prove the relationship between fatty acids and asthma severity.
“Among populations known to be disproportionately affected by asthma, we may find that improving diet and air pollution together has the greatest impact on health,” said Brigham.
New cell that can heal hearts discovered
Researchers have discovered a previously unidentified cell population which could lead to new treatments for patients with injured hearts.
The cell, described in the journal Immunity, was discovered in the pericardial fluid found in the sac around the heart of a mouse with heart injury. The researchers from the University of Calgary in Canada found that a specific cell, a Gata6+ pericardial cavity macrophage, helps heal an injured heart in mice.
The same cells were also found within the human pericardium of people with injured hearts, confirming that the repair cells offer the promise of a new therapy for patients with heart disease. “Our discovery of a new cell that can help heal injured heart muscle will open the door to new therapies and hope for the millions of people who suffer from heart disease,” said Paul Fedak, a professor at the University of Calgary.
“The possibilities for further discovery and innovative new therapies are exciting and important,” said Fedak. Heart doctors had never before explored the possibility that cells just outside the heart could participate in healing and repair of hearts after injury, researchers said.
Unlike other organs, the heart has a very limited capacity to repair itself which is why heart disease is the number one cause of death in North America, they said. “We always knew that the heart sits inside a sac filled with a strange fluid,” said Fedak. “Now we know that this pericardial fluid is rich with healing cells. These cells may hold the secret to repair and regeneration of new heart muscle,” he said.
