An allergy is caused by the immune system fighting substances in the environment that it should see as harmless, known as allergens. These innocent substances become targets, leading to...
The frequency of food allergy has increased over the past 30 years. It is thought that allergies and increased sensitivity to foods are probably environmental, and related to Western lifestyles....

Plant-based protein sources are not the same as animal protein sources. Proteins are made up of amino acids which are the building blocks of every cell and hormone in our body. Meat protein contains all nine essential amino acids, whereas plant-based protein usually lacks at least one of the nine essential amino acids our body needs.
Unripe jackfruit makes a convincing choice for pulled pork alternatives, curries and burgers. But it is almost valueless if you needed protein since jackfruit consists of carbohydrates. Vegan burgers are made up of beans, but this is not a complete protein source.
One study found that 25% of vegans (mainly women) had very low blood iron levels, compared to 0% of omnivores.
Plants like whole grains, legumes and spinach are high in iron but is not always the best type. Animal sources contain haem iron. Non-haem iron, found in plants, is not as well absorbed by the body.

It’s a popular practice to take Vitamin C tablets or drink orange juice to boost immunity and ward off the common cold. However, Vitamin C, or ascorbic acid, does not prevent or cure the common col...
Nobel Prize winner Linus Pauling had some studies published which were claiming that large doses of Vitamin C can cure illnesses like cancer and heart disease, along with the flu, but so far the claims have been largely inaccurate, though a few studies reported a shorter duration of the illness in some people.
Vitamin C activates key enzymes in our bodies and acts as an antioxidant. It protects the organs (like lungs) from pathogens. This Vitamin is crucial for the body to launch an effective immune response. All the more reason to consume citrus fruits, and vegetables like the Indian Gooseberry.
Supplements don’t work as effectively and extremely large doses have side effects like nausea, diarrhea and stomach ache.

All the foods that you regularly eat are ones that you learned to eat. Everyone starts life drinking milk. After that, it’s all up for grabs.
But in today’s food culture, many people seem to have acquired uncannily homogenous tastes: food companies push foods high in sugar, fat and salt, which means we are innately incapable of resisting them but that the more frequently we eat them, especially in childhood, the more they train us to expect all food to taste this way.

What statistics are not particularly effective at telling us is how many others – whether overweight or underweight – are in a perpetual state of anxiety about what they consume, living in fear of carbs or fat grams and unable to derive straightforward enjoyment from meals.

Ultra-processed foods like white bread, cereal, chips, and wafers are remarkably common, convenient, affordable, extremely profitable for the makers, come in strong flavors and are aggressively ma...
We consume ultra-processed foods every day without even realizing it.
Most cooked foods can be termed as 'processed foods', but ultra-processed foods are in a different domain, with few people having the clarity to differentiate.
A cooked carrot is processed food, but a bag of industrially-produced, carrot-flavored veggie puffs are ultra-processed and are still aimed at toddlers as a portion of natural food. Other examples include frozen peas or pasteurized milk.

Complex carbohydrates are found in fiber and starch and are beneficial for brain health as they release glucose slowly into our system, helping stabilize our mood. Simple carbohydr...
Our cells generate energy through oxidation, but oxidation also reduces the dopamine and serotonin in the brain and creates oxidative stress.
Antioxidants found in brightly colored foods like fruits and vegetables act as a defense against oxidative stress and inflammation in the brain and body. Antioxidants also repair oxidative damage and scavenge free radicals that cause cell damage in the brain.
Omega 3 are polyunsaturated fatty acids that are involved in the process of converting food into energy. They are important for the health of the brain and the communication of its feel-good chemicals dopamine, serotonin and norepinephrine.
Omega 3 are essential nutrients that are not readily produced by the body, so we must include foods high on it in our diet.

Our brain weighs just 2% of our body weight, yet consumes 20% of our energy requirements. Even when not active, it will burn roughly 400 calories every day.
The most efficient brains burn the least calories. Efficient brains can save a task quickly and then go into a kind of standby mode.
Our vestibular system is responsible for balance. A gel is located inside our ears and tells our brain if we are going right or left.
When we spin in a circle, the gel keeps moving when we stop, resulting in disorientation. When the loss of balance is severe, the brain interprets it as poisoning. That is why the loss of balance can result in nausea.

Detox diets are generally short-term dietary interventions designed to eliminate toxins from your body.
A typical detox diet involves a period of fasting, followed by a str...
Detox diets rarely identify the specific toxins they aim to remove. The mechanisms by which they work are also unclear.
There is little to no evidence that detox diets remove any toxins from your body. However, your body can clear itself of most toxins through the liver, feces, urine, and sweat.

Food is most nutritious at the point of harvest. After that, fresh produce starts degrading.
Once picked, that fruit or veg is using its own nutrients to keep its cells alive. Vitamin C fou...
Refrigeration slows down the process of nutrition degradation. The nutritional loss varies from product to product.
Spinach loses 100% of its vitamin C content in seven days at room temperature and 75% if refrigerated. Carrots lose 27% of their vitamin C content when stored at room temperature for a week.
However, when vegetables are frozen, including spinach, they lose significantly less vitamin C, because freezing pauses the process of oxidization.
As soon as produce is harvested, it's a nutritional race against time.
Frozen produce has one problem: before it's frozen, it's blanched - heating food up for a few minutes at high temperatures to inactivate enzymes that degrade texture and color. Blanching also reduces nutrient content.

We have always thought of ourselves as an organism. New studies point towards us being Superorganisms, with many organisms teaming up to become what we define as 'us'.
Our state of mind gets affected by our gut bacteria, which is part of our Microbiome.
Probiotics are live bacterial supplements and Prebiotics are the dietary fiber that promotes bacterial growth. In various experiments, scientists have been able to alter our stress response, anxiety levels and reduce mental health problems by administering Probiotics/Prebiotics in our stomach.
Psychobiotics is an upcoming class of medicines geared towards promoting psychological health through the alteration of your microbiota (Gut Bacteria).
Doctors have known since long that certain mental health problems do have their origin in the gut, like inflammation, but a detailed study on mice is now being done, with large-scale studies on humans in the offing.
