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.

Studies have found that fermented foods directly increase the diversity of the gut microbiome, improve blood sugar control, and lower systemic inflammation.

From yogurt to sauerkraut to kimchi and kefir, almost every culture on earth has fermented foods in its traditional cuisines. Fermentation originated naturally, long before human civilization, when wild yeasts and bacteria accidentally encountered sugars, spontaneously triggering chemical transformations.

Now, fermented foods are re-emerging as research is demonstrating their nutritional pros. They are preserved using an age-old process that not only boosts the food's shelf life and nutritional value, but can give your body a dose of healthy probiotics, which are live microorganisms crucial to healthy digestion, according to Dr. David S. Ludwig, a professor of nutrition at the Harvard School of Public Health.

Fermented foods are packed with probiotics that serve a plethora of purposes. Other benefits include:

1. Improves immune function
2. Protects against hostile bacteria
3. Improves digestion and absorption of food and nutrients.
4. Produce essential nutrients like vitamins K and B
5. Synthesize short-chain fatty acids
6. Increase bioavailability of iron, zinc, and other minerals

What Are Fermented Foods?

Fermented foods are defined as foods or beverages produced through controlled microbial growth and the conversion of food through enzymatic action. These foods are transformed by microbes intentionally, unlike spoiled foods that are altered unintentionally by microbes.

A lot of fermented foods are produced across the globe, including dairy, vegetables, grains, and legumes. Some of the popular ones that are consumed are sourdough bread, kimchi, curd, miso, etc.

When we eat fermented foods, the bacteria survive the digestion and make their way to the small and large intestines, where they secrete beneficial compounds, inhibit intestinal pathogens, and influence the composition of the gut microbiome.

Not all fermented foods contain live microorganisms. Major examples of this are chocolate and coffee.

1. Chocolate is made by fermenting cacao beans with natural yeasts and bacteria, which are killed off when the beans are heated and roasted.
2. Coffee is considered a fermented food because beans typically undergo a fermentation process. The microbes are destroyed when coffee beans are roasted.

The flavor profiles of both chocolate and coffee are influenced by fermentation, leading to the creation of that unique and rich flavour loved by everyone.

“A big part of the reason that chocolate or coffee tastes different is because of the way that it’s fermented in that region and the microbes that are present in that region,” said Chris Damman, a microbiome and nutrition expert and gastroenterologist at the digestive health center at the University of Washington Medical Center.

How To Eat Fermented Foods

Ideally, one or two servings of fermented food should be eaten daily, and new varieties should be tried to gain the full benefits of consuming different types of polyphenols, probiotics, and their by-products.

Fermented foods like kimchi, pickles, and sauerkraut can be relatively high in sodium, so avoid them when on low-sodium diets or with hypertension. Eating too many fermented foods can create problems for those who have a compromised immune system.

For those who are well, look for ways to incorporate fermented foods in your favorite dishes. Here's how:

• While having a burger or stir fry, add a topping of kimchi;
• While eating salad, top it up with sauerkraut sauce;
• If granola or cereal is being eaten, replace milk with kefir.
• Craving a snack? Have a bowl of plain Greek yogurt topped off with fruits instead of junk items.

How to Add Fermented Foods To Your Daily Meals

1. Add kimchi to everyday meals. Kimchi can be used as a side dish in sandwiches, wraps, burgers, rice bowls, or even on a toast for that spicy probiotic boost.
2. Swap regular yogurt with Greek yogurt. There is a wide variety of yogurt available that can be enjoyed by garnishing with fruits and granola.
3. Instead of sugary soft drinks, drink Kombucha- a fermented tea that offers a tangy flavor and refreshing feel.
4. Incorporate fermented soy products like Tempeh and Miso in stir fries, soups, salads, and gain bowls.

Bonus tip: Start with small portions and gradually increase the intake to allow your digestive system to adapt.

In a bid to strengthen food hygiene and safety standards, the Food Safety and Standards Authority of India (FSSAI) has directed Food Business Operators (FBOs) across the country to ensure that only food-grade, corrosion-resistant knives, blades, and cutting equipment are used in food handling and processing operations.

The directive, issued under Schedule 4 of the Food Safety and Standards (Licensing and Registration of Food Businesses) Regulations, 2011, also requires FBOs to maintain all cutting equipment in a sound and hygienic condition. In addition, the food regulator has asked State Food Safety Commissioners and Regional Directors to maintain strict vigilance and ensure compliance during inspections.

FSSAI Flags Use of Unsafe Cutting Equipment

"Schedule 4 of the aforesaid Regulations requires that equipment, utensils and food-contact surfaces used in food handling, preparation, processing, packaging and storage shall be made of food-grade, non-toxic, corrosion-resistant materials and shall be maintained in a hygienic condition so as to prevent contamination of food," FSSAI said in its advisory.

The regulations further require that such equipment and utensils be adequately cleaned and disinfected at appropriate intervals to prevent food contamination.

According to FSSAI, it has come to the regulator's notice that certain food businesses are using rusted, corroded, chipped, painted, damaged, or otherwise unsuitable knives, blades, and cutting equipment during food handling, preparation, processing, cutting, slicing, and packaging operations.

The food regulator noted that the use of rusted, corroded, chipped, painted, damaged, inadequately cleaned, or non-food-grade cutting tools can result in physical, chemical, and microbiological contamination of food.

What Did The FSSAI Advisory Recommend?

FSSAI has directed all Food Business Operators to ensure strict compliance with the following measures:

• Only food-grade, corrosion-resistant knives, blades, and cutting equipment should be used in food handling and processing operations.
• Knives, blades, and cutting equipment must be maintained in a sound and hygienic condition and be free from rust, corrosion, chipping, paint, cracks, breakage, or any other defect that may contaminate food.
• Rusted, corroded, chipped, damaged, or otherwise unsuitable cutting equipment must be immediately removed from use and replaced.
• Adequate cleaning, sanitization, and sterilization procedures, wherever applicable, must be followed at prescribed intervals.

FSSAI warned that any non-compliance observed will attract action under the Food Safety and Standards Act, 2006, and regulations made thereunder.

Unsafe Food A Major Public Health Concern

Unsafe food continues to pose a significant global health challenge. According to a recent World Health Organization (WHO) report, unsafe food causes approximately 866 million illnesses and 1.5 million deaths worldwide every year.

Children under five years of age bear a disproportionate burden, accounting for 29 per cent of the health impact linked to unsafe food. In 2021 alone, unsafe food was associated with an estimated 143,000 deaths among children in this age group.

The WHO also warned that exposure to chemical hazards in food, including methylmercury and lead, can damage the developing brain and result in lifelong neurological and developmental problems in children.

Eggs are a great source of protein. At the same time, they are one of the most common foods that cause allergies in children.

A new study conducted in Australia showed that introducing eggs to children before the age of one may reduce the risk of allergy by 17 per cent. The findings were published in the journal JAMA Pediatrics.

Jennifer Koplin, Associate Professor at the Child Health Research Centre at The University of Queensland, said: “Australia has one of the highest rates of food allergy in the world, with one in 10 infants allergic to one or more foods".

To curb the allergy rates, the Australian infant feeding guidelines, issued by the Australasian Society of Clinical Immunology and Allergy in 2016, revolutionized allergy prevention by advising parents to introduce well-cooked egg and smooth peanut butter soon after starting solid foods, generally around six months of age.

The research, led by a team from UQ and the Murdoch Children's Research Institute, examined 7,200 children in two Australian population-based studies to assess whether egg allergy rates had declined since the introduction of the guidelines. The risk of allergy decreased by 17 per cent among babies who started eating eggs early.

“Most parents followed the guidelines, and these results provide reassurance that this advice will help reduce the chance of their child developing an egg allergy,” Dr Koplin said.

Lesser Allergy In Infants With Eczema

According to Associate Professor Rachel Peters of the Murdoch Children's Research Institute, the reduction in egg allergy was more pronounced in babies with eczema, a known risk factor for food allergies. Among these children, egg allergy rates were reduced from 35 per cent to 22 per cent.

“The introduction of the 2016 guidelines was a major change from most advice given in the 1990s and early 2000s, which recommended parents delay giving eggs and other allergenic foods until 1–3 years of age if there was a strong family history of allergy,” Dr Peters said.

Allergenic Foods Before Age One

Other common allergy-causing foods, such as cow's milk, fish, sesame, wheat, and tree nuts, are also recommended to be included in a child's diet before one year of age. Dr Koplin, however, urged for more research into food allergies.

Common Symptoms of Egg Allergy

According to the Mayo Clinic, egg allergy symptoms usually start a few minutes to a few hours after eating eggs or foods containing eggs. While egg allergies can occur as early as infancy, most children outgrow their egg allergy by age 16.

Egg allergy symptoms can include:

• Skin swelling or itchy bumps called hives — the most common egg allergy reaction.
• Stuffy or runny nose and sneezing, also known as allergic rhinitis.
• Digestive symptoms such as cramps, upset stomach and vomiting.
• Asthma symptoms such as coughing, wheezing, chest tightness or shortness of breath.
