The green Mediterranean diet builds on the traditional Mediterranean diet that focuses on fruits, vegetables, and other plant-based foods. The diet also includes unique additions, apart from what we already know being part of the Mediterranean diet. In the green Mediterranean diet, things like green tea, Mankai duckweed, and walnuts, all of this offers enhanced heart health benefits as compared to the Mediterranean of standard version.

This diet was created in 2020, this diet also encouraged a more sustainable and health-focused way of eating.

How does it work - the Green Diet?

The researchers for the first time introduced the green Mediterranean diet in 2020 which enhances cardiometabolic benefits of the traditional Mediterranean approach. It emphasizes plant-based foods and limits animal products to promote heart health and reduce inflammation. This diet can also help with weight management, lower the risk of chronic conditions like diabetes, and support environmental sustainability.

What one needs to follow?

Similar to the traditional version, the Green Mediterranean diet also follows the same dietary guidelines:

Women: 1,200–1,400 calories per day

Men: 1,500–1,800 calories per day

Physical activity is also encouraged to maximize benefits. While any plant-focused Mediterranean diet could be considered "green," the official version includes specific foods:

• Green tea: 3–4 cups per day
• Mankai duckweed: 100 grams, providing protein and antioxidants
• Walnuts: 28 grams daily

What foods can you include?

In the green diet, the importance is to on more plant-based foods, which includes:

• Fresh fruits and vegetables
• Nuts and legumes
• Olive oil, herbs, and spices
• Whole grains

However while this diet too retains animal-based proteins from the traditional Mediterranean diet, the foods like meat, fish or eggs are limited, More attention is given towards the alternatives like tofu, beans, nuts and quinoa.

What foods should you avoid?

The diet minimizes or eliminates:

• Butter and high-fat dairy products
• Foods high in added sugars
• Processed and red meats

How can you follow a meal plan on this diet?

Start with half a cup of oatmeal with fresh fruit and cinnamon and a cup of green tea as your breakfast.

Moving on to lunch, get a smooth of Mankai duckweed, one cup of fruits or vegetables, and unsweetened plant-based milk.

In between, you can also munch on a handful of walnuts, and another cup of green tea.

Lastly, end your day with grilled salmon with cooked spinach, brown rice and a cup of green tea for your dinner.

What are the benefits?

Heart Health

Studies show that following the green Mediterranean diet for six months can lower blood pressure and "bad" LDL cholesterol—two key risk factors for heart disease.

Visceral Fat Reduction

Visceral fat, which accumulates around the abdomen, is linked to various health issues. Research found that the green Mediterranean diet led to double the visceral fat loss compared to the standard version over 18 months.

Environmental Benefits

Reducing meat consumption can significantly lower greenhouse gas emissions. Switching to a green Mediterranean diet can be a meaningful step toward protecting the planet.

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.”

A 20-year-old girl came in with a three-year history of missing periods, sometimes for three to four months at a stretch. She had also noticed increasing facial hair, a common sign of hormonal imbalance. She was thin-looking and had a normal body weight, with no history of significant weight gain. Further evaluation, however, showed that she had PCOS along with metabolic abnormalities.

Her case highlights an important misconception: PCOS does not always come with weight gain. Women with normal body weight can also develop the condition, and appearance alone cannot determine whether someone has PCOS.

Why Can Symptoms Persist Despite Eating Healthy?

Many women with PCOS focus on eliminating sugar, carbohydrates or processed foods, but overlook whether their diet provides enough protein, fibre and essential nutrients. PCOS can affect menstrual cycles, ovulation, androgen levels and metabolic health, and insulin resistance does not affect everyone in the same way.

Diet is also only one part of management. Hormonal factors, physical activity, sleep, genetics and individual metabolic health can influence symptoms. Persistent symptoms do not necessarily mean that someone is eating incorrectly.

Build a Balanced Plate Instead of Cutting Foods

Poha, upma, idli, rice and roti can all be part of a balanced diet. The focus should be on the overall meal rather than eliminating familiar foods.

A balanced meal can include:

• Protein such as dal, curd, paneer, tofu, eggs, beans or sprouts
• Vegetables, whole fruits and other fibre-rich foods
• An appropriate portion of whole or minimally processed carbohydrates
• Healthy fats from nuts and seeds

Carbohydrates do not need to be eliminated. Pairing them with protein and fibre can improve satiety and contribute to better overall metabolic health.

Common PCOS Diet Myths

One common myth is that every woman with PCOS needs to follow a very low-carbohydrate diet. Another is that being thin means PCOS is unlikely. Neither reflects the full picture.

Overly restrictive diets can also result in inadequate nutrition and may be difficult to sustain. The goal should be a balanced eating pattern rather than a growing list of foods to avoid.

Do Not Overlook Essential Nutrients

Iron may require attention when menstrual bleeding is heavy or prolonged, while vitamin B12 can be relevant when animal foods are limited. Calcium and vitamin D are also important when dietary intake is inadequate. Supplements should be considered according to individual needs and medical advice rather than taken routinely.

Management Goes Beyond Diet

Regular physical activity, adequate sleep and a consistent routine can support overall metabolic health. Depending on symptoms and individual needs, medical treatment may also include medicines to regulate periods, manage specific hormonal symptoms, address insulin resistance where appropriate, or support fertility.

PCOS is generally a long-term condition rather than one with a single permanent cure, but its symptoms and associated metabolic concerns can be effectively managed.

When Should You Seek Medical Advice?

Women should consider medical evaluation if they experience:

• Repeatedly irregular periods or gaps of several months
• Increasing facial or body hair or persistent acne
• Difficulty conceiving
• Persistent changes in menstrual or hormonal patterns

The goal of PCOS management is not to eat less or eliminate more foods. It is to understand the individual pattern of symptoms and build sustainable habits that support nutritional, hormonal and metabolic health.
