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.

Recent insights from medical experts show that even people who eat very less can gain weight due muscle mass, stress, and their body’s movement during the day.

Dr Mohit Bhandari, a robotic bariatric and endoscopic weight loss surgeon, founder and director of Mohak Bariatrics and Robotics at Bhandari Hospital Indore notes some people eat whatever they want without gaining weight, while others struggle even with dieting.

The secret lies in the complex interplay of genetics, metabolism, and environmental factors that influence weight management.

This is why are you are putting on weight, according to Dr Bhandari:

1. Metabolism Differences

The speed at which the body burns calories is different for every individual. A slower metabolism means that even consuming small amount of food can lead to gain.

Individuals with high level of physical activity are less likely to be obese as they mean calories quicker.

2. Hormonal And Lifestyle Factors

Hormones like thyroid hormones, cortisol, and play a major role in weight regulation. Stress, lack of sleep and Insulin sensitivity are also factors that lead to fat storage in the body.

3. Loss Of Muscle Mass

Consuming a snack rich in carbohydrate with 10-20 grams of protein before and immediately after strength training sessions further acts as a responsible factor in gaining weight.

4. Gut Health And Digestion

Additionally, it can also trigger inflammation, which interferes with normal metabolism and insulin function, encouraging fat storage.

People are switching from weightlifting and training in the gym to real world strength training.

By strengthening multiple muscle groups at once, it enhances balance, posture, and overall physical efficiency. And one of the best ways to do this is by adopting the farmer's walk

What Is Farmer’s Walk?

Here’s Why Farmer’s Walk Has Gained Popularity:

1. Builds Body strength

Meanwhile, the legs including the quadriceps and hamstrings support the lower body’s endurance.

2. Improves Balance And Posture

Overall, this exercise also regulates spinal and musculoskeletal health.

3. Supports Recovery

It can rebuild strength and stabilize mobility without exceeding tissue healing thresholds.

4. Time Efficient

It can help build strength, improve balance, and boost endurance all at the same time by ensuing coordination among different muscles of the body, making it useful for physical therapy and everyday fitness.

5. Proper Diet and Care It is crucial to fuel your body and make it ready for such a comprehensive exercise.

Proteins such as legumes, tofu and supplements support muscle repair and growth making them an excellent source.

Hydration is the key factor that prevents fatigue and muscle cramps.

Before any extensive workout, warm up thoroughly with light cardio or stretching for about 15-20 minutes.

Ultra Processed Foods (UPF) should be treated more like cigarettes than foods. A new study by researchers at Harvard, the University of Michigan and Duke University noted that UPFs have more in common with cigarettes than with fruits and vegetables and thus require tighter regulation.

Treat Ultra Processed Foods More Like Cigarettes Than Food: What Did The Study Find Out?

Their findings, published on February 3 in the healthcare journal Milbank Quarterly, suggest that both industries have historically engineered products to maximize consumption and potentially drive addiction-like behaviors.

According to the researchers, both cigarettes and ultra-processed foods are developed using similar strategies aimed at influencing reward pathways in the brain. The study suggests manufacturers carefully calibrate ingredients to optimize the “dose” of sugar, fat or salt, ensuring rapid sensory satisfaction that encourages repeated consumption.

The paper draws from addiction science, nutrition research and public health history to highlight these overlaps. The authors concluded that many UPFs demonstrate behavioral and consumption patterns that resemble addictive substances, even if they differ biologically from tobacco.

Professor Ashley Gearhardt, a clinical psychologist at the University of Michigan and one of the study’s authors, said she often hears patients describe their eating patterns in language similar to addiction. She explained that many individuals report intense cravings for products like soda and sugary snacks, acknowledging their health risks but finding it difficult to stop consuming them.

Treat Ultra Processed Foods More Like Cigarettes Than Food: What Are UPFs?

UPFs refer to food products that are heavily industrially manufactured using ingredients rarely found in home kitchens. These often include additives such as emulsifiers, artificial flavors, preservatives and coloring agents. Common examples include sugary soft drinks, packaged snacks, biscuits, instant meals and processed meats.

Unlike minimally processed foods such as fruits or vegetables, UPFs are typically designed for longer shelf life, convenience and enhanced taste appeal.

Treat Ultra Processed Foods More Like Cigarettes Than Food: The Role Of Marketing And “Health Washing”

The researchers also examined marketing strategies used by food companies. They argue that claims such as “low fat” or “sugar free” may create a perception of health benefits while distracting from overall nutritional quality. The study compares this tactic to cigarette advertising in the 1950s, when filters were promoted as safety innovations despite offering limited protection.

The authors believe such marketing can delay regulatory action by creating confusion among consumers and policymakers.

While tobacco is not essential for survival, food is a basic human necessity, making regulation far more complex. However, Professor Gearhardt noted that it should still be possible to distinguish between potentially harmful ultra-processed foods and healthier dietary options, much like alcoholic beverages are regulated differently from other drinks.

The researchers argue that UPFs meet several established criteria used to identify addictive substances, including product designs that may encourage compulsive consumption. Regardless of whether UPFs qualify as addictive in a strict scientific sense, the authors emphasize that their link to rising health problems remains well documented.

The study recommends adopting strategies similar to tobacco control measures, including stricter marketing regulations, industry accountability and structural public health interventions.

However, not all experts fully agree with the comparison. Professor Martin Warren, chief scientific officer at the Quadram Institute, acknowledged parallels but cautioned against drawing direct equivalence between nicotine addiction and UPF consumption. He suggested that it remains unclear whether UPFs are chemically addictive or whether they primarily exploit behavioral preferences and convenience.

Professor Warren also noted that health risks associated with UPFs may partly stem from their replacement of nutrient-rich whole foods.

A Growing Global Concern

Dr Githinji Gitahi, chief executive of Amref Health Africa, warned that the expansion of ultra-processed food markets, especially in regions with weaker regulatory systems, is placing additional strain on public health infrastructure. He emphasized that without stronger government-led interventions, the rising burden of non-communicable diseases could overwhelm healthcare systems.

As research continues to explore the long-term health effects of ultra-processed foods, the debate highlights a larger question: whether modern food environments are shaping consumer choices in ways that demand stronger regulatory oversight.
