Leafy greens, we all know are one of the healthiest foods on the earth. It offers so much, the benefits are countless, whether it is brain health, heart health or to control your blood sugar levels. But there is always a debate between which one is better. Spinach or kale?

So let's get into it!

Kale, we often must have heard its name listed as a "superfood". The reason is because of the rich nutrients it has to offer. However, both, spinach and kale are powerhouse leafy greens, rich in various nutrients.

If one must break down its nutrients, then we can broadly divide it between the fiber content, vitamin K, vitamin C, vitamin A, calcium, and folate.

Fiber

All leafy greens are rich in dietary fiber and thus is essential for feeding your gut microbiome. This is the community of good bacteria that lives in your gut and supports your digestive health. The recommended daily amount or the RDA of fiber is 25 grams per day. So, if you go for a cup of raw spinach, this gives you around .7 grams of dietary fiber, whereas one cup of raw kale gives you a bit more. It has .9 grams of fiber.

A study published in M J Lifestyle Med titled . Closing America's fiber intake gap: Communication strategies from a food and fiber summit, found that most Americans actually do not get their RDA for fiber met. So, adding spinach and kale could be a great way to give your RDA fiber a start!

Vitamin K

Vitamin K is necessary for blood clotting or lowering blood flow following an injury so that the wound can heal. In addition to calcium and vitamin D, it also supports healthy bones. While some animal products and fermented foods include vitamin K2, a 2020 study titled Vitamin K2 needs an RDI separate from vitamin K1, notes that lush greens like spinach and kale have vitamin K1.

The recommended daily intake of vitamin K is 120 microgrammes (mcg). A cup of raw kale has 82 microgrammes of vitamin K, while a cup of raw spinach contains 145 microgrammes.

Vitamin C

It is a water-soluble vitamin and antioxidant that protect cells from damage and supports immune health. While it is often attributed to citrus fruits like oranges, vitamin C can also be found in leafy greens and both kale and spinach could be a great source. US Food and Drug Administration (FDA) recommends around 80 milligram of daily vitamin C. In one cup of raw spinach, you can get 8.5 milligrams, while kale provides 20 milligrams of daily vitamin C.

Vitamin A

As per the FDA, vitamin A is important not only for your immune system, but also for your eye health. One must have at least 3,000 international units daily. The Office of Dietary Supplements notes that spinach and kale contain compounds called carotenoids, which our bodies convert to a usable form of vitamin A. This way you can have these leafy greens in your diet to fulfill your requirement of vitamin A. In one cup of spinach, you can get 2,810 international units of vitamin A, whereas in one cup of kale, you will find 1,010 international units of vitamin A.

Calcium

Leafy greens are a rich source of calcium, an important nutrient which supports healthy bones and teeth, nerve communication, and muscle movement. The RDA for calcium in adults is 1,300 milligrams and one cup of raw spinach contains 30 milligrams of calcium, whereas in kale, it has 53 milligrams.

Folate

It is a B vitamin which is best known for its important in pregnancy and that provides neural tube defects like spina bifida in fetuses. The RDA for folate is 400 micrograms in pregnant mothers and 600 for those who are lactating. In one cup of spinach, one can get 58.2 micrograms of folate, whereas kale contains 13 micrograms of folate.

How to Decide Your Diet?

Now that you know the nutrients that kale and spinach contain, you make your own decision. This could be decided based on your requirement. The best way to do this is by talking to a healthcare expert, or a nutritionist who can recommend you better based on your body's need.

Festivals bring family and friends together and all enjoy traditional sweets and savouries to rich gravies and deep-fried delicacies. However, the joy of celebration and eating more than regular can sometimes lead to bloating, acidity, heaviness, gas and discomfort. Understanding how digestion works and how Ayurveda explains it through the concept of Agni can help us celebrate with smoothness in our digestive system.

During festival, we may eat larger portions, enjoy several rich dishes at one meal, or eat again before we feel actual hunger. Digestive discomfort often occurs when we eat food without knowing agni, consume fatty or fried foods, eat too quickly or combine multiple rich dishes in one meal, untimely, without proper digestion of previous meal. For some people, carbonated drinks and particular food can increase gas or bloating. Stomach stretches when we overeat, and high-fat and heavy meals may delay stomach emptying, leaving us feeling uncomfortably full for longer period. Eating rapidly can also cause us to swallow more air. For people prone to acid reflux, large meals may get worsen with heartburn and regurgitation. Occasional bloating after a heavy meal is common.

Ayurveda explain digesting and metabolism through concept of Agni. The concept of Jatharagni relates particularly to the digestion and metabolism of food. Ayurveda also describes Mandagni (diminished digestive capacity) which will be associated with symptoms such as heaviness, reduced appetite and sluggish digestion etc..., from a practical perspective, the Ayurveda emphasis on eating according to digestive capacity, avoiding excessive food intake and maintaining regular dietary habits aligns sensibly with modern nutrition advice. Classical ayurvedic text emphasise the importance of maintaining balance Agni, for overall health, well-being and preventive care; however, Agni is a traditional Ayurvedic concept and should not be directly corelated with any single modern physiological process.

Five Healthy Eating Habits For Festive Season

1. Portion awareness: Enjoy your favourite dishes of festival but begin with moderate portions. Eat in moderate speed and pause before taking a second serving.

2. Avoid excessive food in one sitting: Multiple preparations which are fried and sugary can make a meal unnecessarily heavy. Choose a balanced plate with vegetables, protein-rich foods and appropriate portions of carbohydrates and Fats.

3. Hydration: Drink warm water regularly throughout the day sip by sip. Limit excessive carbonated beverages if they are causing any discomfort or not.

4. Digestion time: Avoid lying down immediately after meals. A gentle 10–15-minute slow walk after eating may support general digestive comfort, then if needed lie-down on left sided.

5. Routine and mindful eating: Avoid skipping meals to compensate for feasting. Eat when comfortably hungry after analysing agni, pay attention to fullness and maintain regular sleep, physical and mindfulness activities.

Festive eating need not mean deprivation or discomfort. Ayurveda's emphasis on Agni encourages us to respect individual digestive capacity, and guidance from nutrition reinforces moderation, mindful eating and balanced meals. Enjoy the foods you love, savour every bite, observe and recognise when you are comfortably full of stomach.

Seek medical evaluation if bloating is persistent, frequently recurring or accompanied by severe abdominal pain, repeated vomiting, diarrhea, blood in the stool, unexplained weight loss, difficulty swallowing or any GI related symptoms. Severe or sudden abdominal pain requires urgent medical attention and assessment.

This festive season, let celebration nourish your well-being not leave you feeling weighed down.

According to Indian food regulations, there is a specified amount of pesticide residue that can legally remain in tea leaves. But the Food Safety and Standards Authority of India (FSSAI) has proposed new limits for two types of pesticides used in agriculture, including a limit for one that is lower than those in the United States and Japan.

The draft amendment, announced by the Ministry of Health and Family Welfare on October 17, 2026, proposes maximum residue limits (MRLs) for acetamiprid and imidacloprid in tea. The move is aimed to give tea farmers, manufacturers and regulators clearer standards to follow.

Under the proposal, the maximum permitted residue of acetamiprid in tea would be 20 milligrams per kilogram (mg/kg), or 20 parts per million (ppm). For imidacloprid, the proposed limit is 50 mg/kg.

The draft regulations were published in the Gazette of India on October 16 and are yet to be finalised. These are proposed legal limits, not measurements showing how much pesticide is present in tea sold in India.

India's Proposed Limits For Pesticide Residue In Tea

India has proposed a limit of 20 ppm for acetamiprid, which is lower than the corresponding limit of 30 ppm in Japan and 50 ppm in the United States. For imidacloprid, the proposed Indian limit has been formulated with reference to international Codex standards.

These figures do not mean that tea sold in the US or Japan necessarily contains more pesticide residue. Maximum residue limits specify the highest concentration legally permitted in a food product. Actual residue levels depend on pesticide use, farming practices, and testing results.

A higher legal limit also does not automatically mean that a food product is unsafe. Risk assessment requires additional information about the pesticide, the amount consumed, the level of exposure and its toxicological profile.

The proposed tea standards are part of FSSAI's review of pesticide residue regulations. The government said an earlier regulatory measure aimed at delisting 13 pesticides that were known to have higher toxicity.

The regulator also highlighted India's comparatively low average pesticide use, at less than 0.5 kg per hectare, against an estimated global average of 2.38 kg per hectare.

What Are Acetamiprid And Imidacloprid?

Acetamiprid and imidacloprid belong to a class of insecticides called neonicotinoids. They are used to control agricultural pests. Although they help protect crops, their safety depends on how they are used, the residues left behind and the amount people are exposed to.

Acetamiprid acts on the nervous system of insects. Toxicological research has raised concerns about its potential effects on the nervous system and reproductive development at sufficiently high exposure levels.

Imidacloprid also works the same way and its excessive exposure can cause toxic effects, including neurological symptoms.

The health risks stem from long-term, low-level exposure that depend on the dose, way of exposure and duration. The proposed residue limit alone cannot establish whether a particular tea product poses a health risk.

Health Risks Of Pesticide Residues In Tea

The health risks associated with pesticide residues depend on the chemical involved and how much enters the body. High exposure to certain insecticides can affect the nervous system, while toxicological studies have also investigated possible effects on reproduction.

For consumers, the key question is whether pesticide exposure through food remains within levels considered acceptable under established safety assessments.

Maximum residue limits are designed to help regulate pesticide use. They are generally set using data on pesticide use, residue levels, dietary exposure and toxicological assessments.

The actual exposure for tea drinkers also depends on how much residue remains in the dry leaves and how much transfers into the brewed drink. Residue levels in dry tea cannot be directly compared with the amount consumed in a cup.

McMaster University’s release names packaged snack foods, sugary breakfast cereals, soft drinks, instant noodles and ready-to-eat frozen meals as examples of ultra-processed food.

What counts as ultra-processed

Chips, sweet breakfast cereals, processed sweet yogurts, soft drinks, instant noodles and frozen ready meals all fall under the ultra-processed category, according to Russell de Souza, a health research professor at McMaster University and registered dietitian, speaking to CTV News.

What the study found

McMaster University’s release names packaged snack foods, sugary breakfast cereals, soft drinks, instant noodles and ready-to-eat frozen meals as examples of ultra-processed food.

The study was led by McMaster’s Population Health Research Institute (PHRI) and enrolled nearly 9,000 Canadians aged 35 to 69 with no history of heart disease, according to McMaster. Participants came from two PHRI studies, the Canadian Alliance for Healthy Hearts and Minds and the Prospective Urban and Rural Epidemiology-MIND study. Each completed detailed dietary questionnaires and had an MRI brain scan, reviewed by neurologists who didn’t know their diets.

Published October 15 in JAMA Network Open, the study found that participants with the highest intake were 40 per cent more likely to show tiny areas of brain damage than those who ate the least, per McMaster. These changes cause no obvious symptoms. They are considered early warning signs that can appear years before a stroke or memory problems.

Ultra-processed food made up about 25 per cent of participants’ daily food servings on average. For the heaviest consumers it was 45 per cent, compared with 16 per cent for the lowest group, McMaster reported.

Ultra-processed food made up about 25 per cent of participants’ daily food servings on average. For the heaviest consumers it was 45 per cent, compared with 16 per cent for the lowest group, McMaster reported. As intake rose, whole-food intake fell. Fruits, vegetables, grains and other minimally processed foods made up 41 per cent of daily servings in the highest-intake group, against 68 per cent in the lowest. Russell J. de Souza said this suggests ultra-processed foods displaced healthier whole foods rather than simply being eaten on top of a usual diet.

“I would not have expected this finding, frankly,” said de Souza, who is also an associate scientist at PHRI. The participants were middle-aged Canadians with no heart problems and no other reported health concerns, he noted. He added that this kind of damage is usually associated with conditions seen at a much older age, according to McMaster.

A stronger link in women

The association between ultra-processed food and brain damage appeared stronger among women. Those in the highest consumption group were nearly twice as likely to show signs of brain damage as those in the lowest, according to McMaster.

Participants with the highest intake also carried more body fat and more deep belly fat. McMaster’s release says this fat is linked to inflammation and blood vessel damage that can also reach the brain.

Senior author Sonia Anand, a senior scientist at PHRI, said the findings suggest the link between diet and brain health may be detectable before people notice memory or thinking problems. She said it adds to evidence that what Canadians eat from their 30s through their 60s shapes brain health later in life, per McMaster.

Correlation, not yet proof

Because participants were assessed only once and not followed over time, the researchers couldn’t determine whether ultra-processed food directly causes these brain changes, McMaster noted. De Souza said longer-term studies with repeated MRI scans are needed to find out whether cutting back can slow or prevent them. He said such follow-up is ongoing.

Speaking to CTV News, Anand said some participants whose diets were more than 45 per cent ultra-processed showed a combination of silent stroke and a pre-stroke profile. She said the team observed an independent effect of ultra-processed food on the damage seen in the scans. In the same interview, de Souza acknowledged that avoiding these foods isn’t equally easy for everyone, with many people struggling to make ends meet. He encouraged eating at home, buying local and using supermarket sales. Some participants are now returning for follow-up MRIs, with results expected in early 2028.
