My cooking challenge is still open – By Dr Hector Perera : London

There are far too many cooking programmes in British TV but the only thing is I didn’t figure out any technique of energy saving in cooking. The contestants or even the famous chef’s just cook without due care for any wastage of energy, may be because they do not have to meet the energy bill.

Poisonous gases given out while cooking

Researchers now understand that the process of cooking food and even simply operating stoves particularly gas appliances can emit a cocktail of potentially hazardous chemicals and compounds. Within our homes, these pollutants are less diluted than they are outdoors, and in the absence of proper ventilation, they often get trapped inside. In cold weather countries they hardly open the windows to let these gases escape may be because they are unaware of these poisonous gases. Most of the times, the houses have double glazed doors and windows to prevent any heat loss and that is quite natural but what about the poisonous gases that emit while cooking? Most of the times they have extractor fans to get rid of these gases but there must be some ventilation in the kitchen while cooking. I think these little points must be pointed out but the TV chefs hardly care about the safety. The cooker rings are at full blast while they cook and they are do not care about the energy wastage.

Cooking, what is it? By Dr Hector Perera – London

The proposal I find most congenial both as a cook and as a chemistry teacher is this.  Cooking is the whole series of operations used by humans to turn raw materials, mainly animal carcasses and harvested plants, into food, that is, into something edible, digestible and nutritious. Those operations which I’ll talk about is energy wasted in cooking.

What is cooking?

Cooking is one of those everyday words that everyone knows. But what does it really mean? Is reheating leftovers cooking? How about making an emulsified salad dressing? Scrambling eggs? Baking cookies? Back home in Sri Lanka majority of people didn’t have the present day modern facilities such as gas and electric cookers, microwaves and ovens. They mainly depended on firewood for cooking. Even at our home including our mum used firewood for cooking. Most of the times a kitchen servant helped cooking and we call her “Kussi amma”. Majority of the present day people in Sri Lanka have these facilities just like in Western countries but they waste plenty of energy that is gas and electric during the process of cooking. Most British TV chefs hardly care about energy wastage in cooking. To believe me one should watch these British TV cooking programmes.

At its most basic, cooking means applying heat to food. But cooking is as much about the ways heat changes the food as it is about the heat itself. That’s because heating food does more than just make it hotter. It changes the food in other ways, too.

Trans fat is considered by many doctors to be the worst type of fat you can eat

Dr Hector Perera London

Unlike other dietary fats, trans fat also called trans-fatty acids both raises your LDL (“bad”) cholesterol and lowers your HDL (“good”) cholesterol. A diet laden with trans-fat increases your risk of heart disease, the leading killer of men and women. Here’s some information about trans-fat and how to avoid it. In a C=C double bond if there are two groups are on the same side of the C=C bond then they are on CIS arrangement. If the groups such as CH3 or even H atoms on the opposite side of the C=C double bond then they are in TRANS position. They are the CIS and TRANS.

What Is Cholesterol?

Dr Hector Perera London

 

To understand high blood cholesterol, it helps to learn about cholesterol. Cholesterol is a waxy, fat-like substance that’s found in all cells of the body.

Your body needs some cholesterol to make hormones, vitamin D, and substances that help you digest foods. Your body makes all the cholesterol it needs. However, cholesterol also is found in some of the foods you eat. Butter, ghee, hard margarines, lard, dripping and goose fat, fatty meat and meat products such as sausages, Full fat cheese, milk, cream and yogurt, Coconut and palm oils and coconut cream. These food are supposed to have lots of bad cholesterol but if we limit the amount we eat then it would not do much harm.

Why Chicken Skin Is Good For You

Dr Hector Perera London

When eat chicken curry along with other curries and rice, we hardly think of removing the skin before we eat, never thought about any healthy points either. Chicken up to twice or thrice a week is good for you. Chicken, along with fish and turkey, is white meat and often recommended for a healthy lifestyle. Your chicken intake in your daily meals can be in many different healthy ways such as baking or grilling chicken breast or serving it with a variety of sauces and vegetables. It is, however, important that this chicken be skinless and certainly not fried.

Here are some evidence-based health benefits of turmeric or “Kaha”

Dr Hector Perera London

Turmeric contains bioactive compounds with powerful medicinal properties. Now we know that turmeric is the spice that gives curry its yellow colour. It has been used in India for thousands of years as a spice and medicinal herb. Recently, science has started to back up what the Indians have known for a long time. It really does contain compounds with medicinal properties. These compounds are called curcuminoids, the most important of which is curcumin.

Greasy unhealthy food

If you travel along Kandy Colombo road, turn off to Kirindiwela road. A few miles from there you would be surprised to see a restaurant that offers meals for just one price. You can eat as much as you like for just one price. Sounds not bad at all. There are plenty of choices as well. One morning we went there then there were milk rice, appa, pittu, string hoppers and pol roti and many more. I am sure Sri Lankans know exactly what I mean. I cannot name them all here so why not drop in there and see for yourself.  They have extended their branches to Mount Lavinia as well. Then once we dropped in there for lunch, I couldn’t believe the choice of dishes and different kinds of rice available, just for one price. Now may be they have more branches as well. One thing, the takeaway or eat in food in Sri Lanka are much healthier than other takeaway food. Nearly all five star hotels have, eat as much as you like service but at a price.

If you have no time to go out to get a takeaway meal, just give them a ring and pay cash or card, it will be delivered to your doorstep in a matter of minutes so who would be tempted to home cook? I have seen mopeds are on the move especially in Colombo city area and even in highly developed Battramulla area.

Don’t get us wrong, we love to cook as much as the next person, but sometimes we need a break. Whether you’re celebrating a special occasion or didn’t have time to buy groceries, it’s good to treat yourself to a night on the town. And luckily, eating out doesn’t have to break your budget. Many restaurants offer great deals on appetizers, pasta and more. Lots of tasty food for a super low price? Sounds like a win-win to us. Check out the best restaurant deals at your favourite chains. 

Buffalo Wild Wings: Buy One, Get One Wings

It’s no surprise that some meals are loaded in calories, as it’s essentially three meals in one. When you order this dish they have to choose three different meats and two different sides and that’s on top of the roasted street corn, French fries, Chile-garlic toast, and pickles that already come with the dish. Indulging in this kind of meal will have you consuming over three days’ worth of the recommended sodium limit, and clocking in at 2,440 calories. This dish would require about 7.5 hours of walking just to burn it off so would you like it?

What are calories?

Dr Hector Perera London

A calorie is a unit that measures energy. Calories are usually used to measure the energy content of foods and beverages. In order to lose weight, you need to eat fewer calories than your body burns each day.

How to Reduce Calorie Intake without Starving Yourself

It is known that in order to gain weight, more calories need to be entering your body than leaving it. Conversely, if more calories leave your body than enter it, then you lose weight. That being said, just cutting calories without regards to the foods you eat is usually not a sustainable way to lose weight. Although it works for some people, the majority of people end up hungry and eventually give up on their diet. For this reason, it is highly recommended to make a few other permanent changes to help you maintain a calorie deficit in the long term, without feeling starved.

Here are 5 evidence-based diet/lifestyle changes that have been shown to help people lose weight in numerous studies. Eating more protein can reduce appetite, cut cravings by 60% and increase the amount of calories you burn. Protein is the only food group that provides us with the nine essential amino acids to make muscle tissue. Without those amino acids, we would not build or make muscle tissue, resulting in muscle wasting and malnutrition.

The ordinary people hardly think of the healthy aspect of the food, they just eat

Dr Hector Perera London

The magazine Health Which? Examined the nutritional content of typical meals from Chinese, Indian, Thai, Italian and Tex-Mex menus.
Recommended daily guidelines (men/women)
These are the daily recommended amounts for men and women
Fat 95g/70g, Saturates 30g/20g, Calories 2,500/2,000, Sodium 2.5g/2g, Fibre 18g, Sugar 70g/50g.
In particular they looked at levels of fat (including saturated fat), sugar, fibre and sodium – all of which can be bad for health in high quantity.

The researchers found that certain dishes from each type of cuisine contained worryingly high levels of fat and sugar that is one way they make them so tasty.

Some Chinese dishes were particularly unhealthy again due to fat and sugar in them. A portion of battered sweet and sour pork with egg fried rice contained 60g of fat and 44g of sugar that means far too much the recommended dose. Even in frying rice they add fat, thinking they are making them very tasty. And the popular dish crispy duck had around 31g of fat per portion.

Plenty of dangerous chemicals, sometimes germs are found in some takeaway food

Dr Hector Perera London

Fast food restaurants usually have a walk up counter and/or drive-thru window where you order and pick up your food without having to wait long. There is no such thing as a “bad” food, but these are some foods you should try not to have on a regular basis. Because fast food is high in sodium, saturated fat, trans-fat, and cholesterol, it isn’t something you should eat often. The ill effect of fast food and the potential danger that it possesses by its regular consumption is shocking. One of the things is obesity. Regular consumption leads to increase in cholesterol levels, nutritional deficiencies, cardiac disorders, loss of muscle mass, depression and even sexual dysfunction. Soaked in trans-fat and loaded with calories, fast foods are labelled as ‘health hazards’ by many leading medical professionals but most people eat them on regular basis.

Some chemicals in fast food

The processed meat used in some fast food contain nitrates, nitrites, artificial sweeteners and monosodium glutamate which increase blood flow and can trigger a migraine attack. This monosodium glutamate is also known as “Ajina Motto” is widely available in most Asian grocery shops. Recently I visited an Asian shop in Tooting area and I found these chemicals in small bags just like normal salt. This is a salt that gives a better taste to food, a flavour enhancer. I added this chemical to some fresh beef and left it over night and on the following day; I could pull out strands of comb beef using a fork. The smell and taste was no difference to canned comb beef.
