Who needs cooking oil?

With the controversy surrounding various cooking oil brands and production batches as the Kenya Bureau of Standards withdraws some from the market, it's time to think matters frying.

Consumers have decried the rising cost of cooking oil due to the vagaries of inflation, which has escalated domestic budgets in the face of stagnant salaries and income sources.

The ongoing Russian-Ukraine crisis disrupted global supply chains, including oil, whose rising cost saw a rise in the cost of production. Also affected was cooking oil whose cost was also worsened by global prices of crude palm oil, which is essential in manufacturing cooling oil.

Although prices of palm oil have been dropping down, they are still high compared to a year ago.

That the Kenya shilling has continued losing to the US dollar has only made matters worse. Prices of cooking oil doubled with a litre in some areas going for Sh440.

Something else, Kenya maintained a higher import duty on vegetable oils than other East African Community countries, further contributing to the escalating cost of cooking oils.

This scenario has seen most Kenyans resorting to kadogo economy, basically the buying of household items in calibrated quantities one can afford. For cooking oil, most have resorted to cooking oil dispensers as they do with milk dispensers.

But do people really need cooking oil? Well, for starters an array of food types does not require cooking oil or cooking fat.

In fact, Prof Christopher Ataro, a plant bleeding scientist, says there are no foods that can't do without cooking oil. There are different ways of cooking such as boiling, grilling and roasting, he adds.

Some foods though have natural fats while others have more health benefits due to their low-fat levels. We are here talking about meats like beef, chevon (goat meat), veal, mutton, chicken, pork and fish. Most produce a lot of natural oil when cooked under low fire over time.

Adding cooking oil into such meats only increase their fat/oil content of which too much is dangerous to the body. Bad cholesterol, high blood pressure, increased risk of heart disease, diabetes, certain cancers and obesity are some of the consequences, warns former hotel nutritionist Grace Chege.

She adds that adding cooking oil on meats can also reduce one's appetite. Chege says that all forms of meat, red or white have their own natural oil and need no processed cooking oil or fat to cook them.

Vegetables cooked under steam, she says, shortens the duration thus making them retain their natural properties and value, especially vitamins.

"If you cook vegetables for a long time they lose vitamins which are the main benefits of eating vegetables", says Chege.

"Vegetables must not change colours as they're healthier, appealing and flavoured when they look green. Overcooking turns them from green to brown," she says.

The body needs vitamins, calcium, potassium and folate to prevent diseases.

Some Kenyans reckon that chips cannot do without deep frying which requires a lot of oil. But chips can be air-fried. And if anything air-fried chips are better than deep fried ones?

Prof Ataro says: "Yes, as already mentioned, deep frying breaks the oil and reduces its quality, making it rather unhealthy. Air drying is like grilling without oil."

Chege advises that people go for low-fat foods as restricting fat intake is beneficial, especially for people with gallbladder or pancreas disease.

Prof Ataro explains that high intake of cooking oil increases high concentration of toxic chemicals called aldehydes thus increasing risk of diseases like arthritis, heart disease, dementia, gallbladder and pancreas disease while low intake of cooking fats decreases the or controls risk of the same diseases.

Low-fat diets also prevent heartburn, cuts weight and improves cholesterol levels.

Chege says all grains should be cooked, and remain healthy, when prepared without cooking oil like the mixture of maize and beans popularly known as githeri and which is a staple diet of communities in Central region. Muthokoi, common among the Kamba, also falls in this category.

Other foods which should be made without cooking oil include legumes like peas, lentils, mushrooms, vegetables and pumpkins.

Starchy foods like cassava, potatoes, ngwaci (sweet potatoes), nduma (arrow roots) and yams are best boiled. Eggs can be boiled or pouched

Other foods that don't require cooking oil include mrenda, managu, ugali, maize (which can be boiled or roasted), beans, mukimo (pounded mixture of maize, bean, potatoes and nduma leaves), rice, cassava and spaghetti.

As for those who buy animal fat from butcheries, well, Prof Ataro advises against it.

"Animal fats are mostly either saturated fat or trans fats, which are potentially harmful to your health," he explains.

Unlike other dietary fats, trans fats are the worst. Also called trans-fatty acids, trans fats raise 'bad' cholesterol and lowers 'good' cholesterol.

"The better option is vegetable oil. Processed vegetable oils fall in the category of polyunsaturated oils (found in vegetables, nuts and seed) and are good for your health," says Prof Ataro.

"We spoil them by subjecting them to heat during deep frying. Their smoke points or boiling points are mostly low and their structure breaks under high heat

"Groundnut oil has a high smoke point and does not break as easily, but the oil is not abundant and is costly," adds Prof Ataro.

But boiled foods can be tasteless to the palate. How can they be made more palatable?

Prof Ataro advises that one can add spices such as coriander, black pepper, celery and mint or unprocessed oily foods like crushed groundnut or coconut.
