What you need to know about vegetarianism

Living healthy requires maintaining a healthy diet. No diet may be healthier than meals dominated by fresh, all-natural vegetables and fruits.


Lately, more and more people have shifted to vegetarian meals because scientific research demonstrated the adverse effects of animal meat.


Nutritionists explain that the high amount of animal fat present in meat, dairy, and other animal products may be probable factors leading to the onset of diabetes mellitus, obesity, colorectal cancer, high blood pressure, and coronary artery disease.


To avoid these diseases, nutritionists have long expounded on the health benefits of high intake of fruits and vegetables.


However, people generally have many misconceptions about vegetarianism or the practice of eating foods from the plant kingdom.


This article attempts to clear these misconceptions and bring to light what the said lifestyle is about.


Vegetarians may be classified into four groups. Vegans eat no animal foods, while semi-vegetarians generally avoid meat but consume poultry and selected animal foods.


Meanwhile, lacto-ovo-vegetarians avoid meat, poultry and fish, but take in milk and eggs. Finally, lacto-vegetarians consume milk products but not other animal foods. Some vegetarians also go as far as avoiding clothing made from animal products like fleece, fur, and leather.


More so, others avoid processed foods, alcoholic beverages, and foods bred with pesticides.


Historically, vegetarianism can be traced from philosophical beliefs, specifically religious traditions and teachings of Buddhism and Hinduism.


The said religions shun away from animal flesh due to their doctrine upholding self-denial, reincarnation, and the blessedness of all forms of life.


However, during the 19th century, the practice has transcended religious boundaries when the Vegetarian Society, a British non-religious organization, became famous in 1847.


Modern vegetarians uphold the rejection of meat in their campaign for animal welfare, labeling the killing of animals for consumption as a violation of their rights. The practice has already gained worldwide acceptance.


Some people contend that the vegetarian diet is insufficient in meeting the daily nutritional requirements. However, dieticians have explained that plant-based meals are low in cholesterol, saturated fat, and salt.


Likewise, plant-based meals may be planned in order to obtain the essential nutrients normally obtained from meat, fish, and poultry.


Vegetarians may consume diets dominated by fruits, vegetables, cereals and grains. In place of meat products, lacto-ovo-vegetarians may use nuts, lentils, eggs, nuts, peanut butter, dry beans, and peas. Vegetarians avoiding milk may find other sources of calcium and Vitamin D-enriched foods.


Also, vegans may have to take vitamin and mineral supplements to ensure adequate intakes of nutrients that may only be obtained from animal-based meals.


Consciousness on healthy living involves awareness on the different options and forms of vegetarianism. Here’s to a healthy lifestyle and well-being to all of us!

Is saturated fat in coconut good for your heart health

You probably know that saturated fats are bad fats that can cause all kinds of heart related diseases. Did you know that and the humble coconut oil has 92% saturated fats? Then why is it that there are many advocates of taking coconut oil as a health supplement? Isn't that contradictory?


Supporters of virgin coconut oil argue that coconut oil helps them to improve skin condition, have more energy and even to lose weight. Huh? consuming saturated fats to lose weight? How is that possible?


These advocates hail the virgin coconut oil as one of the hottest new nutritional supplement to hit the health and nutrition industry in years. This logic flies against conventional wisdom, isn’t it?


Saturated fat and there are plenty of it in coconut oil has been the villain for heart diseases. When hydrogenated vegetable fat (trans fat) was invented like in margarine, it was supposed to replace unhealthy saturated fat like in butter and was thought to be a healthier form of fat only until it was discovered in the last few years that trans fat is more dangerous to your heart health than saturated fat.


It is with this thinking that proponents of coconut fats is now arguing that not all forms of saturated fat may be bad and the coconut oil may be one of them. Dr. Bruce Fife, a US based naturopath and author of “The Coconut Oil Miracle” remarked during a press conference in Singapore last month, “Not all saturated fatty acids act in the same way. The fat in coconut oil is different from most other fats and has many health giving properties”.


He further added that, “The Lauric acid (I coconut oil) boosts immunity, has antioxidant properties and is being investigated in reducing viral load in HIV patients. You should also take into account the size of the carbon chain in the fatty acid. Most of the oils and fats we consume are long–chain fatty acids. Coconut oil is the richest source of medium-chain fatty acids, which actually behave very differently from the long-chain versions.”


“Medium-chain fatty acids in coconut oil boost the body’s metabolic rate and promote weight loss. They are broken down immediately in the liver to produce energy and are not stored as fat,” he added.


So is the consumption of coconut fats good or bad for health? It’s very controversial isn’t it?


Let’s hear it from another expert Dr Annie Leong, deputy director of the nutrition department at the Health Promotion Board. “There is not enough evidence to prove that medium-chain saturated fats can reduce heart risk.”


Nutritionist Anna Jacob argued that, “Kerala is the coconut capital of India and it also has the highest rates of heart disease. While it is possible to argue that Indians are genetically predisposed to heart disease, but a diet high in saturated fat as well could heighten that risk.”


My question is that since Indians are more prone to heart disease, then the high rates of heart disease should be spread evenly throughout India and not just in Kerala, don’t you think so? Therefore, I am still a little skeptical.


So who is right and who is wrong? So is coconut oil saturated fat good or bad for your heart health? Well, the jury is still out there as far as I am concerned. I for one will make a conscious effort to avoid consuming coconut oil too often until the coconut debate is more conclusive with empirical evidence that the coconut oil is good for heart health.
