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.

Navratri is a time of prayer, devotion and fasting for many people. While fasting is an important part of the celebration, what you eat during this period matters too. Choosing the right foods can help you stay energetic, avoid unnecessary hunger and maintain healthy blood sugar levels. A few simple changes to your fasting meals can make a real difference.

What Should You Eat During Navratri Fasting?

Fasting does not mean you have to compromise on nutrition. Instead of depending mainly on potatoes, sabudana and fried snacks, try including a variety of foods in your meals.

Some healthier choices include:

• Fresh fruits: Apples, guavas, pears and oranges provide vitamins, minerals and fibre. Choose whole fruits instead of juices.
• Vegetables: Cucumber, bottle gourd and pumpkin can add variety and nutrients to fasting meals.
• Protein-rich foods: Curd, paneer, milk and nuts help keep you satisfied for longer.
• Fasting grains: Buckwheat (kuttu) and amaranth (rajgira), where permitted, can be included in moderate portions.
• Healthy fats: Use small amounts of nuts, seeds and cooking oils instead of relying on deep-fried snacks.

How to Balance Carbohydrates, Protein and Fibre

One common mistake during fasting is eating too many carbohydrate-rich foods while missing out on protein and fibre. This can leave you feeling hungry soon after a meal and may cause blood sugar levels to rise quickly.

For better balance, combine fasting grains or potatoes with protein-rich foods such as curd or paneer. Include permitted vegetables and choose whole fruits for additional fibre. Keep portions of sabudana khichdi, potato dishes and fasting flour rotis under control.

Remember, foods considered traditional or healthy during fasting can still raise blood sugar when eaten in large quantities.

Which Fasting Foods Should You Limit?

Sabudana, potatoes, sweets and fruit juices can raise blood sugar levels, particularly when consumed in large portions. Fried foods such as puris and pakoras can also add excess calories.

Whenever possible, choose boiled, steamed, roasted or lightly sautéed foods. Limit added sugar and avoid combining several starchy foods in the same meal.

Stay Hydrated and Watch Your Portions

Drinking enough water is important, especially if your fasting routine limits when you can eat or drink. Where permitted, unsweetened buttermilk can be another option. Avoid relying on sugary drinks to manage hunger or tiredness.

Instead of eating one very large meal after hours without food, choose moderate portions during your permitted eating periods.

How Can People with Diabetes Fast Safely?

For people with diabetes, fasting needs extra care. Changes in meal timings and food intake can increase the risk of low or high blood sugar, as well as dehydration. The risk may be greater for those taking insulin or certain diabetes medicines.

Here are a few important precautions:

• Speak to your doctor before starting a fast.
• Discuss whether your medication timings or doses need adjustment.
• Monitor your blood sugar as advised by your healthcare team.
• Do not ignore symptoms such as sweating, dizziness, confusion or unusual thirst.
• Stop fasting and seek medical advice if your blood sugar becomes dangerously low or high, or if you feel unwell.

The takeaway: Navratri fasting can be both meaningful and mindful of your health. Simple choices, such as eating balanced meals, limiting fried foods and controlling portions, can help you feel better throughout the festival. If you have diabetes, plan your fast with your doctor to observe the tradition without putting your health at risk.

Eating peanuts may help lower the risk of developing type 2 diabetes. Researchers have identified changes in blood fats that could help explain the association. The findings indicate that peanuts may impact the body’s lipid metabolism. The body weight also plays an important role in the association.

The study, published in The American Journal of Clinical Nutrition in 2026, combined a dietary intervention of six months with data from a large cohort to investigate how eating peanuts changes circulating lipids and how these changes relate to cardiometabolic disease risk.

Link Between Peanut Consumption & Cardiometabolic Disease Risk

Researchers from the German Institute of Human Nutrition Potsdam-Rehbruecke and the University of Barcelona analysed data from two studies.

The first was the ARISTOTLE clinical trial, which involved 63 healthy adults aged 18 to 33. Participants were randomly assigned to consume one of three options daily for six months: 25 grams of skin-roasted peanuts, 32 grams of peanut butter or 32 grams of control butter made with peanut oil.

Researchers measured changes in participants’ blood lipids before and after the intervention. They then examined data from the EPIC-Potsdam cohort, which followed more than 27,000 people and included information on 774 cases of newly developed type 2 diabetes and 545 cases of cardiovascular disease.

Using a technique called lipidomics, which analyses fats circulating in the blood, the team identified a pattern of lipid changes associated with peanut consumption. They called this the “peanut lipidomic signature”

What Were The Findings?

Peanut consumption altered 51 groups of fatty acids within different lipid classes, especially lipids containing very-long-chain saturated fatty acids (VLCSFAs).

These included changes involving C22:0 and C24:0 fatty acids. Researchers found that these fatty acids were incorporated into specific lipid classes, including ceramides, suggesting that peanut consumption was linked with restructuring of the blood lipid profile rather than simply an increase in fat levels.

“This is not merely a simple increase in fat levels, but a complex 'remodeling' of the lipidome,” said first author Dr. Inés Domínguez-López.

Professor Matthias Schulze explained the significance of the findings, “By characterizing this specific peanut lipid signature, we have uncovered a potential biological marker that links dietary fat quality to metabolic outcomes.”

When researchers examined the relationship between these lipid changes and disease outcomes in the larger cohort, they found that a higher PeLS was associated with a modestly lower risk of type 2 diabetes.

For every one-standard-deviation increase in the signature, the estimated risk was 11% lower. But the signature was not associated with a lower risk of cardiovascular disease in this analysis.

Body Weight's Role

Body mass index (BMI) emerged as a possible explanation for much of the association between the peanut-affected lipid signature and type 2 diabetes risk.

Researchers estimated that BMI could explain approximately 89% of the observed association, although the estimate was inaccurate. This suggests that body weight or related metabolic processes may help understand the relationship.

Domínguez-López said, “This suggests that the positive metabolic effects of these specific peanut-derived lipids may be linked to their ability to support a healthier body weight or stabilize metabolic processes related to adiposity.”

Peanuts contain unsaturated fats, fibre, protein and several micronutrients, making them essential in a balanced diet. Replacing foods rich in saturated fats or highly processed snacks with unsalted peanuts may help improve overall dietary quality.

However, the findings do not prove that peanuts directly prevent diabetes. The intervention involved only 63 young, healthy adults, while the association with disease risk was assessed using a separate observational cohort. The analysis cannot establish that the lipid changes themselves caused the lower risk.

Starbucks is facing a class-action lawsuit in the US for marketing eight protein beverages as "sugar-free" despite containing between 13 and 21 grams of sugar in a venti serving. The lawsuit filed in Seattle states the drinks are labelled in a misleading manner that violate federal regulations. In response, Starbucks has denied the claims.

According to Reuters, the sugar comes from lactose, the naturally occurring sugar in milk, rather than sugar added to the beverages. Starbucks says the drinks contain no added sugar and that their nutritional information is available on its website and other platforms.

About The Starbucks Lawsuit

Hagens Berman filed the suit on behalf of three consumers who bought Starbucks’ sugar-free protein drinks in California, New York and Washington.

“Consumers avoid sugar for various reasons, whether that be general health, diabetes and blood glucose levels or other factors, and for many, a staunch mislabeling like this is significant,” said Steve Berman, a co-founder and managing partner of the Seattle-headquartered firm.

The drinks named in the lawsuit include sugar-free vanilla and caramel protein lattes and matchas, along with their iced versions. Starbucks' U.S. website listed a 16-ounce (0.5-liter) Sugar-Free Caramel Protein Matcha with 16 grams of sugar and a 20-ounce (0.6-liter) version of the same drink with 21 grams of sugar.

The drinks are marketed as “sugar-free,” but the amount of sugar in each beverage was also mentioned, including a note that said that they were made without added sugar.

“We believe these claims have no merit,” a Starbucks spokesperson said Monday. “Starbucks has consistently and clearly provided information about its protein beverages, sugar-free options, customization choices and nutritional content across product announcements, menus, marketing materials, Starbucks.com and the Starbucks app, and we intend to vigorously defend ourselves in this matter.”

Naturally Occurring Sugar Vs Added Sugar

The American Heart Association says that naturally occurring sugars are found in foods like milk and fruit, while added sugars are added during the preparation. Lactose in milk is therefore not the same as added table sugar or syrup.

However, “naturally occurring” does not mean the amount is irrelevant or it is completely healthy. Total sugar still contributes carbohydrates and calories, and affects the overall nutritional profile of a beverage.

Health Risks Of Consuming Excessive Sugar

High consumption of sugary foods and beverages can contribute to excess calorie intake and obesity. Excess sugar intake is also linked with a higher risk of conditions including type 2 diabetes and cardiovascular disease. WHO also identifies sugar consumption as a major risk factor for dental caries.

The American Heart Association recommends limiting added sugar to no more than 25 grams per day for most women and 36 grams for men.

Therefore, a drink containing 21 grams of naturally occurring sugar cannot simply be counted as 21 grams of added sugar, but the number still gives consumers useful information about what they are drinking.

Naturally added sugars do not make it fit for consumption, especially for someone monitoring blood glucose. Lactose is a carbohydrate and is broken down into glucose and galactose during digestion.

Therefore, people with diabetes or those specifically trying to control their carbohydrate intake may still need to account for the total carbohydrate and sugar content of a drink rather than trusting terms such as “sugar-free” or “no added sugar.”
