Figure 1: Areca nut

The habit of chewing areca is a habit of great antiquity. Areca is mainly used as food, medicine, social and religious purposes. It is the fourth most commonly used social drug, ranking after nicotine, ethanol and caffeine. Areca preparations and specific ingredients differ by cultural group and individual user.

Be CAUTIONS? Areca nut taken along with tobacco is known to have a deleterious effect of the oral cavity to the extent of causing oral cancer.

But Areca is BENEFICIAL in Some extent. However, not much is documented regarding the advantages of chewing areca nut. Arecoline, the principal alkaloid in areca nut, acts as an agonist primarily at muscarinic acetylcholine receptors. It stimulates the central and autonomic nervous system. This leads to subjective effects of increased well-being, alertness and stamina. In addition to that, it is known to improve concentration and relaxation, with other reported effects including lifting of mood, a sense of well-being, heightened alertness, staving off hunger, aphrodisiac properties and as postprandial digesting. It has also been shown to have cariostatic property. Areca was touted as a folk medicine for digestive and dental health. Areca nut also exerts a direct antimicrobial effect against bacteria, including Streptococcus mutans, Streptococcus salivarius and various other microorganisms in the oral cavity. It was used to facilitate bowel movements and reduce intestinal worms (as used in Ayurvedic medicine).

In conclusion, the use of areca nut chewing has been of centuries old. The general effects of chewing areca nut have much impact not just on the oral cavity but also on the general health of an individual. However, many a times, the deleterious effects can outweigh the general effects to a large extent when it becomes a habit. Unfortunately, the habit is becoming prominent among the younger individuals. This is the key problem in food industry because they need to hire employees who do not chew areca nut on order to concern about food hygiene. In such cases, it is very difficult to restrict the usage, and it becomes mandatory to curb the habit as “habits die hard”.

Figure 1: Garcinia cambogia
A wide variety of weight management strategies are presently available, and some involve the use of dietary supplements marketed as slimming aids. Garcinia extract, (-)-hydroxycitric acid (HCA) can be considered as one such aid. HCA is a derivative of citric acid and can be extracted in plant species native to South Asia such as Garcinia cambogia, Garcinia indica, and Garcinia atroviridis. It is usually marketed as a weight loss supplement either alone or in combination with other supplements.
Garcinia cambogia Desr, known also like “tamarindo malabar”, is a plant pertaining to the family of the Guttifereae. The yellow-orange fruit color has the shape of pumpkin with thin skin and deep vertical sections that form lobes and commonly used like spice or conserving above all of the fish. In the traditional medicine the fruit of the Garcinia finds is used for the stomachache and it is like oral antiseptic in the mouthwashes.

Some researchers have suggested that HCA causes weight reduction by competitively inhibiting the enzyme adenosine triphosphatase-citrate-lyase. In addition to that, HCA can increase the release or availability of serotonin in the brain, thereby leading to appetite suppression. Other suggested mechanisms include inhibition of pancreatic alpha amylase and intestinal alpha glucosidase, thereby leading to a reduction in carbohydrate metabolism.

The most important fact is Animal studies have suggested that HCA causes weight loss, and human trials involving the use of HCA as a weight loss supplement have been carried out and identified that that Garcinia extracts/HCA can cause short term weight loss.

Based on this information, we can suggest that, it is better to incorporate garcenia to your daily diet. But avoid overconsumption. Also don’t cook garcenia added foods in Aluminium pots. Furthermore, further research need to be focused on the effect of other fruits (Garcenia family) extracts on weight reduction.

Obesity is defined as abnormal or excessive fat accumulation in the human body that presents a risk to health by World Health Oraganization. Obesity can be measured using the body mass index (BMI), a person’s weight (in kilograms) divided by the square of his or her height (in metres). A person with a BMI of 30 or more is generally considered obese. A person with a BMI equal to or more than 25 is considered overweight. However, these standards varying from ethnicity to ethnicity. 

Obesity is a major part of metabolic syndrome which is a major risk factor for a number of chronic diseases, including diabetes, cardiovascular diseases and cancer. 

"Once considered a problem only in high income countries, overweight and obesity are now dramatically on the rise in low- and middle-income countries, particularly in urban settings" - WHO

Recent research has been found that Higher rates of obesity and ill-health can be observed in shift workers than the general population (By James Gallagher - Health editor, BBC News website)

Why? There are many reasons associated with this Fact. 

Erratic working schedules lead to consume food away from home mainly in cheap fast food restaurants. They are rich is calorie, sugar, fat (Saturated fat, Trans fat, cholesterol), salt and low in micro nutrients and fiber. Also massive portion size tend to accumulate these unhealthy food inside your body more and more. 

Erratic workers do not eat in a regular pattern and they skip their main meals such as breakfast and lunch. As a result they tend to eat more calorie rich food in night and stomach do not have adequate time for digestion because soon after eat, they go to sleep. This lead to increase abdominal fat which carrying increased risk for cardiovascular diseases. 

Furthermore, these people tend to consume more alcohol and cigarettes in order to prevent loneliness or to obtain a fun. For examples, if group of male employees go around the country for marketing definitely most of the nights they organize party with alcohols.  

On the other hand, they do not have time to engage in physical activities and increased level of stress can also lead to obesity and hypertension. 

"Shift work is becoming increasingly common and it's causing a lot of problems to a lot of people and in particular the link with cancer is becoming stronger (By James Gallagher - Health editor, BBC News website)"

Therefore to alleviate this problem nutrition intervention strategies should mainly target for these set of people as well out of the main set of general population.

Asian palm civet feeding on coffee beans 

It is brewed from coffee beans that have been eaten and partially digested by the Asian palm civet, a catlike wild animal. Producers of the coffee beans claim that the process may increase coffee quality through selection and digestion. Selection happens if the civets choose to eat coffee berries containing better beans. Digestive may increase the flavor profile of the coffee beans that have been eaten. The civet consumes the berries for the beans' fleshy pulp, and then in the digestive tract, fermentation happens. The civet's proteolytic enzymes secrete into the beans, creation shorter peptides and more free amino acids. Passing through a civet's intestines the beans are then defecated with other fecal matter and collected.

Traditionally, the coffee was so rare because harvesters had to scour the rainforest floor looking for civet droppings that contained coffee beans. In recent years, some people have started caging wild civets and feeding them the beans directly.
