Lots of people frown upon reusing cooking oil. However, many are secretly doing it. Who has the heart to throw away expensive oil that looks like it’s perfectly fine for a few more uses anyway?
Actually, there is no written rule when it comes to the number of times that cooking oil can be reused. However, there are a few guidelines that you may use in determining whether or not cooking oil used before can be used once again — this article will get you introduced to some of those that really matter.
Got family members and friends who like spending much of their time in the kitchen frying crispy and delectable treats just like you? Make sure that you repost this article after checking out its entirety.
Oil’s Not Cheap
Everyone knows that frying is unhealthy. Well, it all depends on which type of oil you use for frying — these days, more and more people are discovering the health perks of using healthy plant-based oils for their frying needs.
Unfortunately, cooking oils that are good for you tend to carry steeper price tags than cooking oils that can clog your arteries and expand your waistline.
Among health-conscious individuals, peanut oil is the leading choice for frying — it’s healthy and it has a very high smoke point which means that it won’t burn that easily, thus making it the ultimate frying oil. (Olive oil is not good for frying because it has a low smoke point and is quite expensive, too.)
Because of the cost, it can be very disheartening most especially for budget-conscious individuals to throw away healthy plant-based cooking oils after just a couple of uses.
Trust Your Eyes and Nose
It’s no secret that burnt food is regarded as a carcinogen — something that can increase your risk of suffering from cancer. This is the reason why many are wary of reusing their cooking oils. Also, scientists say that reusing cooking oils can increase free radicals that are also linked to cancer formation.
But before the time comes when used cooking oils are already teeming with cancer-causing free radicals, it’s for certain that you will be enticed to throw it away because of the unusual color and also smell.
This is why it’s a good idea for you to rely on your senses in determining whether or not it’s okay for you to reuse cooking oil — throw it away if it no longer looks and smells like it is fit for frying.
Used cooking oil that is better flushed down the drain rather than placed back in the frying pan looks a lot darker than its original color, and also it’s not unlikely for some really questionable-looking stuff to be on the surface or at the bottom. Further, it’s no longer suited for cooking if it already smells rancid.
Here’s What You Can Do
Most especially if you are using plant-based cooking oil such as peanut oil, they you’re well aware of the fact that it doesn’t come cheap — getting rid of it after using it once or twice can be hard to stomach.
The good news is you don’t really have to throw away cooking oil that’s completely fine to be used for a few more times in the near future.
Once used cooking oil is already at room temperature, remove large pieces of food. Afterwards, strain using a couple of layers of cheesecloth before storing it. Don’t forget to stash used cooking oil in a cool and dry place in your kitchen. Refrain from placing used cooking oil back in its original container together with unused portions.
And by the way, never fry with used cooking oil that’s more than 1 to 2 months old even if it looks and smells like it’s never been used before.
Balanced protein intake better for health
Researchers suggest that excessive consumption of protein for building muscle mass could have a negative impact on the body. However, wide-range of protein is best to maintain balance. Amino acids have long been touted by the fitness and bodybuilding communities for their muscle building benefits. From ultra-bulk protein powders to lean mass-promoting snack bars, there’s no shortage of products available for those seeking a muscle boost.
However, protein’s popularity has also meant that less attention has been paid to researching its potentially negative side-effects.
According to the study published in the Journal of Nature Metabolism, excessive consumption of branched-chain amino acids (BCAAs) may reduce lifespan, negatively impact mood and lead to weight gain.
BCAAs stands for branched-chain amino acids. It’s a group of three essential amino acids: leucine, isoleucine and valine, and are most commonly found in red meat and dairy.
BCAAs great for adding muscle mass, but science says you could pay for it later.
Researchers have investigated the complex role nutrition plays in mediating various aspects of metabolic health, reproduction, appetite and ageing.
“While diets high in protein and low in carbohydrates were shown to be beneficial for reproductive function, they had detrimental effects for health in mid-late life, and also led to a shortened lifespan,” one of the researchers, Dr Samantha Solon explained.
“What this new research has shown is that amino acid balance is important. It’s best to vary sources of protein to ensure you’re getting the best amino acid balance.”
The current research examined the impacts that dietary BCAAs and other essential amino acids such as tryptophan had on the health and body composition of mice.
“Supplementation of BCAAs resulted in high levels of BCAAs in the blood which competed with tryptophan for transport into the brain,” explained one of the researchers, Professor Stephen Simpson.
“Tryptophan is the sole precursor for the hormone serotonin, which is often called the ‘happiness chemical’ for its mood-enhancing effects and its role in promoting sleep. But serotonin does more than this, and therein lay the problem,” he added.
Dietitian and public health nutritionist Dr Rosilene Ribeiro recommend eating a wide range of proteins.
It’s important to vary protein sources in order to get a variety of essential amino acids, through a healthy and balanced diet rich in fibre, vitamins and minerals.
BCAAs are essential amino acids present in protein-containing foods, with red meat and dairy being the richest sources. Chicken, fish and eggs are also nutritious sources of BCAAs.
Vegetarians can find BCAAs in beans, lentils, nuts and soy proteins.
Know the severity of falling sick in the morning
While sickness comes irrespective of the time, the severity of afflictions ranging from allergies to heart attacks differs in the morning from that in the night highlighted a new study. The study was published in the Journal Trends in Immunology which compiled studies, predominantly in mice, that looked at the connection between circadian rhythms and immune responses.
The body reacts to cues such as light and hormones to anticipate recurring rhythms of sleep, metabolism, and other physiological processes. The numbers of white blood cells, in both humans and mice also oscillate in a circadian manner.
Taking into account the above-mentioned facts, researchers in the study found that:
Heart attacks in humans are known to strike most commonly in the morning, and research suggests that morning heart attacks tend to be more severe than at night.
In mice, the numbers of monocytes, a type of white blood cell that fights off bacteria, viruses, and fungi –are elevated in the blood during the day. At night, monocytes are elevated in infarcted heart tissue, resulting in decreased cardiac protection at that time of day relative to morning.
Parasite infections are time-of-day dependent. Mice infected with the gastrointestinal parasite Trichuris muris in the morning have been able to kill worms significantly faster than those infected in the evening.
Allergic symptoms follow a time-of-day dependent rhythmicity, generally worse between midnight and early morning. Hence, the molecular clock can physiologically drive innate immune cell recruitment and the outcomes of asthma in humans, or airway inflammation in mice, the review notes.
“Investigating circadian rhythms in innate and adaptive immunity is a great tool to generally understand the physiological interplay and time-dependent succession of events in generating immune responses,” said senior author Christoph Scheiermann, University of Geneva.
ICMR develops affordable quick test kits for diagnosing genetic bleeding disorders
The Indian Council of Medical Research (ICMR) has developed a cost-effective and rapid point-of-care test kit for diagnosing genetic bleeding disorders such as haemophilia A and Von Willebrand disease (VWD).
Diagnostics which are currently available require special equipment and are expensive.
“Both Haemophilia A and VWD are under diagnosed disorders in our country. There are only handful of comprehensive diagnostic centres for bleeding disorders,” an official at ICMR said.
“Lack of awareness and diagnostic facilities, high cost of tests are some of the factors for under-diagnosis of bleeding disorders in our country,” he said.
According to the ICMR, the kit is the world’s first point-of-care test for specific diagnosis of any common bleeding disorder and costs less than Rs 50 in comparison to existing conventional test that cost around Rs 4,000 to Rs 10,000.
The newly developed kit would help in diagnosis within 30 minutes of blood sample collection. Also, this will be available at any level of health care system including primary health care centres (PHCs) since it does not require any special expertise or infrastructure.
Worldwide, incidence of Haemophilia A is 1 per 10,000 male births and that of VWD is around 1 per cent of the general population.
“In India, there is no epidemiological data. We may have roughly 80,000-1,00,000 severe Haemophilia cases in our country, but the total number registered with Haemophilia Federation India (HFI) is only around 19,000,” the official said.
Patients with severe Haemophilia A or VWD can have life threatening spontaneous or post-traumatic bleeding like brain haemorrhage and gastrointestinal bleeding. In emergency medical setting, it is important to have a quick diagnosis of bleeding disorders for treatment.
This rapid test kit can be used for the diagnosis of menorrhagia cases/ post-partum haemorrhage (PPH), gynecological complications among others.
