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.
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 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.
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.
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.
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.
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.
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.

Love your daily cup of coffee? The way you brew it could make a difference—not just for its taste, but also for your cholesterol levels.
A new scientific statement from the American Heart Association (AHA), published in the peer-reviewed journal Circulation, stated that for most healthy adults, drinking up to five cups of black caffeinated coffee a day (up to 400 mg of caffeine) is safe and may even benefit heart health.
However, the statement, based on a review of the latest evidence on caffeine and cardiovascular health, noted that the brewing method matters because some types of coffee contain compounds that can raise LDL, or "bad," cholesterol.

According to the AHA, moderate consumption of black, caffeinated coffee without added sugar, cream, or flavored syrups has been linked to several cardiovascular benefits.
A review of the latest evidence found that drinking three to five 8-ounce cups of regular black coffee daily was associated with a lower risk of:
"Caffeine consumed in coffee is a key part of daily life for millions of people, and in our review of the most recent research, for most adults, intake of up to 400 mg of caffeine/day, the equivalent of up to five cups of caffeinated coffee per day without added sugars or fillers, is safe and does not increase cardiovascular risk," said Gregory M. Marcus, chair of the scientific statement writing group and professor of medicine at the University of California, San Francisco.
While coffee itself may support heart health, the AHA highlighted one naturally occurring compound—cafestol—that can raise LDL ("bad") cholesterol.
Cafestol is found in both caffeinated and decaffeinated coffee, but its levels depend on how the coffee is prepared.
Cafestol, associated with increased LDL cholesterol levels, is high in unfiltered coffee, including:
In contrast, paper-filtered coffee and instant coffee contain little to no cafestol, making them a better choice for people concerned about cholesterol.

The statement also found that coffee's effect on blood pressure is complex, and they called for more studies to better understand this relationship.
Yet the findings revealed that among people with normal blood pressure, drinking one to three cups a day was associated with a higher risk of developing hypertension, while consuming more than three cups daily was linked to a lower risk.
Although caffeine may temporarily reduce insulin sensitivity, regular consumption of black caffeinated coffee has been linked to a lower risk of Type 2 diabetes. Researchers believe this benefit is likely due to compounds in coffee other than caffeine.
The AHA cautioned that the findings do not apply to energy drinks or energy shots. These products contain much higher concentrations of caffeine—around 40–69 mg per fluid ounce, roughly three to four times more than regular brewed coffee—and have been linked to high blood pressure, abnormal heart rhythms, and other cardiovascular risks, even in healthy adults under 30.
Marcus stressed that there is no one-size-fits-all recommendation for caffeine intake because people respond differently based on age, genetics, medications, underlying health conditions, and how quickly they metabolize caffeine.
He advised people to pay attention to how their body responds to caffeine and discuss their intake with their healthcare provider if they experience symptoms such as palpitations, anxiety, or sleep disturbances.

Nutritious food has become up to 25% more expensive over the past five years, leaving nearly one-third of the global population unable to afford a healthy diet, according to a new report released by the United Nations.
The 2026 State of Food Security and Nutrition in the World, published by the UN Food and Agriculture Organization (FAO), estimates that a healthy diet now costs an average of US$4.28 (S$5.52) in purchasing power parity (PPP) dollars per person per day.
"A healthy diet costs 25% more than it did five years ago. One-third of the global population can't afford it. The cost of a healthy diet shows where agrifood systems investments can have the greatest impact," Máximo Torero Cullen, the FAO's Chief Economist, wrote in a post on social media platform X.

The full report, to be presented on July 21 at the organization's headquarters in Rome, found that the cost of a healthy diet is unevenly distributed across different food groups.
"The challenge is not to produce enough calories; it is to make nutrient-rich foods more affordable," Torero said during a press conference, as quoted by AFP. The full report will be presented July 21 at the organization's headquarters in Rome.
He emphasized that strengthening local food production could significantly lower the cost of healthy diets.
Torero also highlighted two major uncertainties that could further drive up global food prices:

Amid intensified inspections and market surveillance by the Food Safety and Standards Authority of India (FSSAI) to crack down on counterfeit and substandard dairy products, a new survey has found that 6 in 10 urban Indian households are not fully confident about the purity and quality of the ghee or clarified butter they consume.
The survey, conducted by community social media platform LocalCircles, received over 91,000 responses from more than 18,000 urban consumers across 293 districts, revealing widespread concern over adulteration—particularly in loose and unbranded ghee.
According to the survey:
The findings come amid a series of enforcement actions by FSSAI targeting fake and substandard dairy products across India.

In December 2025, FSSAI directed all States and Union Territories to launch a nationwide enforcement drive against the adulteration and misbranding of milk and milk products, including ghee, paneer and khoya, under the Food Safety and Standards Act, 2006.
Since then, the regulator has significantly expanded inspections and surveillance. Recent enforcement actions include:
FSSAI has also issued notices to quick-commerce platforms over complaints of expired and spoiled food products being delivered to consumers.
Made by clarifying butter obtained from cow's milk, ghee is a staple in Indian kitchens and contains approximately 130 calories and 15 grams of fat per tablespoon. It is also a rich source of vitamins A, D, E and K, along with antioxidants.
However, because ghee is high in saturated fat, excessive consumption may raise LDL ("bad") cholesterol levels in some individuals and increase the risk of cardiovascular disease.

Health experts advise people with certain medical conditions to consume ghee cautiously or avoid it altogether.
These include people with:
Doctors generally recommend limiting intake to no more than two teaspoons a day, unless advised otherwise by a healthcare professional.
Food adulteration involves the deliberate addition of inferior or harmful substances to food products, compromising their quality and safety.
According to a 2024 study published in SAGE Open Medicine, consuming adulterated food may increase the risk of:
The study notes that children, pregnant women and older adults are particularly vulnerable to the harmful effects of adulterated food.
