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.

Ultra-processed foods (UPFs), typically high in salt, sugar, and unhealthy fats, have long been associated with obesity, diabetes, hypertension, and other chronic diseases.

Now, new research suggests that the vast majority of foods marketed for toddlers in the US fall into this category. A study led by the University of Texas at Austin found that more than 80% of toddler foods sold in US grocery stores are ultra-processed, while nearly half fail to meet at least one nutrient standard set by the World Health Organization (WHO) for commercial foods intended for children aged 6 to 36 months.

Researchers analyzed 2,783 toddler food products sold across 21 grocery stores in Texas. Using the Nova classification system, they found that 81% of products were ultra-processed, while 49% failed to meet at least one WHO nutrient standard.

Among the products analyzed:

• 81% were classified as ultra-processed.
• 17% exceeded WHO recommendations for sugar.
• 25% exceeded recommended sodium levels.
• 11% exceeded recommended fat levels.
• 12% exceeded recommended energy density.

Products that exceeded WHO recommendations included:

• Fruit pouches (high in sugar)
• Oat bars (high in sugar and calories)
• Mac and cheese (high in sodium and fat)
• Turkey sticks (high in sodium and fat)
• Cheese puffs (high in calories)
• Peanut butter puffs (high in sodium, fat, and calories)

“Many parents may assume that products sold on the baby/toddler food aisles of their grocery stores have to meet certain nutrient standards. Our findings highlight that half of the toddler foods available in local grocery stores do not,” said Erin A. Hudson, a University of Texas at Austin graduate student and science policy fellow with the American Society for Nutrition.

Hudson urged parents "to be vigilant in checking labels and ingredients to determine the nutrient content and processing level of products for their toddlers".

Why Is This Concerning?

The toddler years are a crucial period for developing lifelong eating habits and taste preferences. Diets high in added sugars and ultra-processed foods during early childhood may increase the risk of obesity, diabetes, cardiovascular disease, and other chronic illnesses later in life.

The researchers found that ultra-processed toddler foods were significantly more likely to be high in sugar than less-processed alternatives. Excess sugar intake in young children has been consistently linked to poor health outcomes, including obesity and metabolic disorders.

The findings come as the US Food and Drug Administration (FDA) is considering new guidelines for front-of-package nutrition labels, healthy claims and marketing of food products to children. The US currently does not require warning labels on any food products that are high in sugar, sodium or calories.

What Are Ultra-Processed Foods?

Ultra-processed foods (UPFs) are industrially manufactured products made with ingredients and additives rarely used in home cooking, including preservatives, emulsifiers, artificial sweeteners, colorants, flavor enhancers, and hydrogenated oils. They are generally high in refined carbohydrates, added sugars, unhealthy fats, and sodium, while being low in fiber and other essential nutrients.

Research suggests that diets high in UPFs may promote chronic inflammation, disrupt the gut microbiome, and impair insulin regulation over time, potentially increasing the risk of obesity, type 2 diabetes, cardiovascular disease, and other chronic illnesses from an early age.

The monsoon season offers relief from the heat but also creates the perfect environment for bacteria, viruses, and fungi to multiply. As a result, stomach infections, food poisoning, diarrhea, and indigestion become more common.

Thus, fermented foods act as a natural probiotic to keep the gut healthy during the rainy season. They also support digestion, improve nutrient absorption, and may reduce the risk of digestive problems during the rainy season. However, the humidity can spoil the food.

HealthandMe spoke to experts who stressed good hygiene and freshly cooked meals. They also called for foods to be prepared

and stored safely to prevent contamination.

Common probiotic-rich homemade foods include:

• Curd (dahi)
• Buttermilk (chaas)
• Fermented rice (panta bhat)
• Idli and dosa batter
• Kanji
• Hygienically prepared homemade pickles

Why Fermented Foods Are Good During Monsoon

The experts said that homemade fermented foods naturally contain beneficial bacteria (probiotics) that help maintain a healthy gut microbiome.

"Monsoon brings a natural dip in immunity, and gut health takes centre stage in staying resilient through the season. Fermented foods are one of the simplest ways to introduce live beneficial bacteria that aid digestion and strengthen the body's natural defence mechanisms," Dr. Eileen Canday, Head of Nutrition & Dietetics at Sir H. N. Reliance Foundation Hospital, Mumbai, told HealthandMe.

Riya Oswal, Clinical Nutritionist at Ruby Hall Clinic, said pairing good hygiene with probiotic-rich fermented foods can help support gut health and strengthen the body's natural defenses.

Why Fermented Foods Can Be Risky During Monsoon

Despite their benefits, fermented foods can become unsafe if they are not prepared or stored properly.

"The higher humidity and fluctuating temperatures during the monsoon create favorable conditions for harmful microorganisms if fermentation is not properly controlled," Dt. Deepali Sharma, Clinical Nutritionist at CK Birla Hospital, Delhi, told HealthandMe.

How to Prepare Fermented Foods Safely

Food safety becomes especially important during the rainy season. The experts recommended to:

• Wash hands thoroughly before preparing food.
• Use clean, sterilized utensils.
• Prepare foods with safe drinking (potable) water.
• Use fresh ingredients.
• Follow the recommended fermentation time and avoid over-fermentation in humid weather.
• Cover food properly while it ferments.
• Refrigerate fermented foods promptly after fermentation.
• Store them in clean, airtight containers.
• Consume them within the recommended storage period.

When Should You Throw Fermented Food Away?

Do not consume homemade fermented foods if they show signs of spoilage. Discard them if you notice:

• An unusual or foul smell
• Mold growth
• Discoloration
• A slimy texture
• An excessively sour taste

"Any fermented item that has been maintained at a temperature beyond the normal room temperature for too long must also be avoided, since it might carry dangerous microbes, even if everything seems fine at first glance," she said.

Who Should Be Extra Careful?

While fermented foods are generally safe for healthy individuals, some people should consult a doctor before consuming homemade fermented products, Oswal told HealthandMe.

These include:

• People with weakened immunity
• Patients undergoing chemotherapy
• Organ transplant recipients
• Those receiving immunosuppressive therapy
• People with serious chronic illnesses
• Individuals with uncontrolled gastrointestinal diseases

Sharma added that infants, older adults with reduced immunity, and pregnant women should consume only freshly prepared and properly stored fermented foods during the monsoon to minimize the risk of infection.

The Indian Council of Medical Research–National Institute of Nutrition (ICMR-NIN) has launched a new policy document aimed at tackling childhood obesity and promoting healthier diets and food environments for children and adolescents in India.

Released under the multi-institutional 'Let's Fix Our Food' (LFOF) consortium, which was launched in 2022, the policy comes as India faces a growing burden of obesity and diet-related non-communicable diseases (NCDs), including diabetes, hypertension, cancer and respiratory illnesses.

The document outlines evidence-based recommendations to improve food environments and encourage healthier dietary habits among children and adolescents.

"Evidence-based, multisectoral policy action is essential to create healthier food environments for children and adolescents. Collaborative initiatives such as the Let's Fix Our Food Consortium are important for addressing the growing burden of overweight, obesity and diet-related non-communicable diseases in India," said Dr. M. Srinivas, Member (Health), NITI Aayog.

What Does The Policy Recommend?

The policy outlines recommendations across several areas, including:

• Healthy school food environments
• Nutrition literacy
• Front-of-pack nutrition labelling
• Regulation of unhealthy food marketing to children
• Taxation of foods high in fat, salt and sugar (HFSS)
• Healthier dietary fats
• Salt reduction
• Low-sodium salt substitutes
• Social and behavior change communication
• Youth engagement
• Fiscal measures to promote healthier diets.

India's Growing Obesity, Malnutrition Burden

The policy highlights India's growing double burden of malnutrition.

According to the National Family Health Survey-6 (NFHS-6) fact sheets for 2023–24, the prevalence of overweight children under five has increased to 3.4%, up from 2.1% in NFHS-4 and 1.3% in the previous survey.

The survey also found that although stunting among children under five has declined to 29.3%, acute malnutrition (wasting) remains unchanged at 5.2%, and only 15% of young children receive an adequate diet.

"Malnutrition is no longer only about undernutrition. Rising obesity, driven by unhealthy diets, challenges healthy growth among children and adolescents," said Marie-Claude Desilets, Chief of Nutrition, UNICEF India.

Key Recommendations

The Let's Fix Our Food Consortium was established to generate evidence and drive policy action for healthier food environments, particularly for children and adolescents. Based on multidisciplinary research and expert consultations, the policy recommends:

Stricter Advertising Rules

• Enforce legal restrictions on marketing HFSS foods to children and adolescents.
• Ban misleading health claims and deceptive advertising across all media.

Front-of-Pack Nutrition Labels

• Introduce mandatory, easy-to-read nutrition labels on packaged foods.
• Help consumers quickly identify products high in fat, salt and sugar.

Healthier School Food Environments

• Restrict junk food in and around schools.
• Ensure affordable, healthy food options and monitor school food environments using NEAT-S.

Tax Junk Food

• Levy taxes on HFSS foods and sugar-sweetened beverages to discourage consumption.
• Use fiscal measures to make healthier foods more affordable.

Strengthen National Programs

• Integrate these measures into initiatives such as the Ayushman Bharat School Health and Wellness Programme to promote better nutrition and physical activity.

New Tools to Support Healthy Eating

The consortium also launched practical tools to help schools and adolescents make healthier food choices.

• Nutrition Environment Assessment Toolkit for Schools (NEAT-S): A framework to help schools assess and improve their food environments by promoting healthier canteens.
• Digital Literacy Modules: An interactive e-learning platform and comic books developed by ICMR-NIN to help adolescents understand food labels and reduce their intake of excess sodium and unhealthy fats.

The initiative is supported by several national and international organizations, including UNICEF India, the Global Health Advocacy Incubator (GHAI), the Public Health Foundation of India (PHFI), the World Health Organization (WHO), the Food Safety and Standards Authority of India (FSSAI), and other partners.
