The carotenoid family, which includes lutein, is a source of plant-based antioxidants that give fruits and vegetables their vivid red, orange, and yellow hues. When consumed, these pigments offer several health advantages in addition to feeding plants.

Like its near sibling zeaxanthin, lutein is a crucial portion of the retina, especially in the macula, which is the section of the eye that gives you sharp vision. These nutrients, sometimes referred to as macular pigments, serve as your eyes' natural defensive system.

How Lutein Promotes Eye Health

Lutein, which is rich in antioxidants and anti-inflammatory properties, can help:

• Reduce oxidative stress and free radical damage
• Increase visual clarity and contrast sensitivity
• Reduce glare irritation and protect from blue light exposure
• Protect eye tissue from damaging UV radiation
• Slow down cell damage associated with ageing and eye disorders
• Facilitate visual signal processing in the brain

Recent study reveals that lutein may lessen the risk of myopia (nearsightedness) and prevent premature infants from retinopathy, a disorder that affects retinal development.

Lutein and Vision Disorders: Prevention and Protection

Lutein is extremely beneficial for preventing or treating eye problems such as:

Age-related: Macular degeneration (AMD) is a leading cause of vision loss, impacting millions worldwide. According to research, lutein may assist to slow its progression and minimize the risk of severe visual impairment.

Diabetic Retinopathy: Lutein may lower oxidative stress in diabetic retinopathy, potentially avoiding vision-threatening complications.

Cataracts: Inadequate lutein consumption may raise the chance of developing cataracts, which cause hazy eyes. Lutein-rich diets may lower this risk.

Dry Eye Syndrome: Lutein can alleviate dry eye symptoms such as redness, irritation, and blurred vision by restoring moisture balance.

How Much Lutein Do You Need?

Although there is no official daily requirement for lutein, studies suggest that doses of 10 mg per day, along with 2 mg of zeaxanthin, can help slow AMD progression. Doses as high as 20 mg per day have been declared safe, with no significant side effects other than slight skin yellowing.

Top Food Sources of Lutein

Boost your lutein levels naturally with these nutrient-rich foods:

• Leafy Greens
• Kale
• Spinach
• Broccoli
• Lettuce
• Parsley

Vegetables and Grains

• Corn
• Red peppers
• Leeks
• Peas
• Durum and einkorn wheat

Other Sources

• Egg yolks
• Pistachios

To optimize absorption, pair lutein-rich foods with healthy fats like olive oil, nuts, or avocados.

Supplements: Additional Boost

While diet is the best source, lutein supplements, which are typically produced from marigold flowers, can help fill nutritional gaps. Consult your doctor to establish the best dosage for your needs.

Other Nutrients That Improve Eye Health

The optimal combination of lutein and other nutrients includes:

• Vitamin C strengthens blood vessels by neutralisation of free radicals
• Vitamin E protects retinal cells from causing any form of oxidative damage
• Zinc also facilitates the absorption of Vitamin A in the retina, wherein it hikes up the formation of melanin in order to protect the eyes
• Omega-3 fatty acids (DHA) reduce inflammation to improve retina function

Cancer is one of the most feared diseases in the world today. While we often focus on genetics or environmental pollution, it’s easy to overlook something closer to home—our daily diet. What we eat may quietly be increasing our risk of developing cancer. In a recent video that's making rounds on social media, Dr. Saurabh Sethi, a Harvard-trained gastroenterologist, on his Instagram account @doctor.sethi with 1.1million followers shared a video that highlighted six foods we often eat without a second thought—foods that research has linked to cancer development and progression.

Here’s a closer look at those six foods, and healthier swaps that can protect your health.

Ultra-Processed Meats

Think sausages, bacon, salami, and deli meats. These are convenient and packed with protein—but they come with a big catch. According to the World Health Organization, these meats are classified as Group 1 carcinogens. That means there’s strong evidence linking them to cancer, particularly colorectal cancer.

Dr. Sethi points out that the nitrates and preservatives used to keep these meats fresh can harm the gut lining and trigger cancerous changes over time. If you're craving something savory, try grilled tofu, boiled eggs, or home-cooked chicken instead.

Sugary Drinks

From sodas to packaged fruit juices and flavored iced teas, sugary drinks are everywhere. But did you know they can do more than just spike your blood sugar? According to Dr. Sethi, they also contribute to chronic inflammation—a key player in cancer. Studies have linked excessive sugary drink consumption to a higher risk of breast, pancreatic, and colon cancers.

Want something refreshing but safe? Choose coconut water, lemon-infused water, or herbal teas.

Deep-Fried Foods

Crispy snacks like fries, pakoras, and samosas are comfort foods, especially during monsoon or festive seasons. But when food is deep-fried—especially in reused oil—it can produce a chemical called acrylamide. This compound has been linked to cancer in various studies.

Instead of deep frying, try air-frying, baking, or even pan-roasting your favourite snacks. You’ll cut down on harmful compounds without compromising too much on taste.

Charred or Burnt Meats

Love a good barbecue? Be careful. Cooking meats at high temperatures, especially until they’re charred or burnt, can produce harmful chemicals like heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs), both linked to cancer risk.

Dr. Sethi suggests marinating your meat and adding herbs like rosemary, which can help reduce these chemicals. Or better yet, try steaming, baking, or slow cooking your meals for a safer—and often more flavorful—experience.

Alcohol

Many people assume a drink or two is harmless. But even moderate alcohol consumption can raise your risk of certain cancers, particularly breast and liver cancer. Alcohol affects hormone levels and interferes with the body’s ability to repair DNA.

Healthier alternatives? Fermented drinks like beetroot kanji, kombucha, or even plain sparkling water with lemon can keep you refreshed—without the risks.

Ultra-Processed Packaged Foods

Instant noodles, chips, and ready-to-eat meals might be a time-saver, but they’re loaded with preservatives, artificial flavoring, and very little nutritional value. Dr. Sethi warns that these foods promote chronic inflammation, which is closely linked to cancer.

Choose fresh, homemade options like oats upma, mixed veg khichdi, or millet porridge. These dishes are not only filling but also full of fiber and essential nutrients.

Don’t Forget to Move

Diet is just one piece of the puzzle. Studies consistently show that regular physical activity plays a big role in preventing cancer. Exercise helps regulate hormones, reduce inflammation, and maintain a healthy weight—all of which support your body in fighting off disease.

We have always bee advised to go with the flow and when it comes to diet, the flow means to opt for seasonal fruits. Now that summers are here too in the US, it is the season for stone fruits. The markets will be flooded with stone fruits, and they are of course worth indulging in.

More than the taste, it also has health benefits. What are those?

Stone Fruit - What Are Those?

As per the University of Florida's Horticultural Sciences Department, stone fruits are fruits with edible flesh on the outside and a stone, which is also known as the pit, which protects its seed from the inside.

These fruits are called drupes and they include peaches, nectarines, cherries, plums, and apricots. As per a 2024 report from the US Department of Agriculture (USDA), the demand for these fruits have been on the rise globally and in the US.

What Are The Health Benefits?

Cherries

As per the US Department of Agriculture, cherries have a high calorie count. In one cup of cherries, around 154 grams, 97 of it makes up for calories. It has 25 grams carbs, 2 grams protein and no fat.

It is also a good source of vitamin C, copper, magnesium, manganese, and vitamin B6 and potassium.

It is also rich in antioxidants which helps in protecting your cells from damage caused by free radicals and also reduces inflammatory processes that can put your body at risk of chronic disease.

Peaches

As per a 2014 study published in journal PLOS One, titled Archaeological Evidence for Peach Cultivation and Domestication in China, peaches have been around the world from as far back as 6,000 BC.

The USDA notes that they are low in calorie, contains carbs, protein, no fat, and also has 19% of vitamin C from recommended daily intake (RDI), 11% RDI of vitamin A, and 10% RDI of potassium.

Research, including a 2018 study published in journal Nutrients, titled Dietary Carotenoid Intakes and Prostate Cancer Risk, a 2015 study published in journal Food & Nutrition Research, titled Carotenoids: Potential allies of cardiovascular health? and a 2014 study titled Dietary intake of carotenoids and risk of type 2 diabetes, provide that peach in fact can protect against heart disease, type 2 diabetes, and certain cancers, including the prostate cancer.

Plums

The USDA notes that plums have calories, carbs, protein but no fat. It provides 20% RDI of vitamin C, 10% RDI of vitamin A, and 10% RDI of vitamin K.

They are also high in anti-inflammatory antioxidants, including phenolic compounds, which protect your cells from being damaged by the free radicals.

Lychee

The USDA notes that they are rich in calories, contain carbs, protein, and a bit of fat. They are a high vitamin C source, providing 226% of the RDI. They also provide 7% RDI for folate and 10% for vitamin B6.

Apricots

The USDA notes that they contain calories, carbs, protein and no fat, providing 27% RDI for vitamin C, 64% for vitamin A, and 12% for potassium.

Note: All these fruits also contain fiber between 2 to 3 grams. Before consuming any stone fruit, please consult your doctor to ensure you are not allergic to any of them and to better understand how can it help you.

A new study published in BMJ Nutrition Prevention & Health has found that low-calorie or restrictive diets may be associated with a higher risk of depressive symptoms, particularly in men and people who are overweight or obese. The findings challenge previous research and highlight the potential mental health costs of calorie-cutting diets, especially when followed without proper nutritional guidance.

Healthy vs. Unhealthy Diets: What We Know

Traditionally, diets rich in whole foods—such as fruits, vegetables, whole grains, nuts, lean proteins, and fish—are linked to lower risks of depression. On the other hand, diets high in ultra-processed foods, refined sugars, saturated fats, and processed meats are associated with a greater risk of mental health issues. However, not all diets fit neatly into these categories, and many people follow restrictive eating plans for various health reasons. This new study set out to explore whether these restrictive diets themselves may be linked to depressive symptoms.

The Study: Diet Patterns and Depression Scores

Researchers analyzed data from 28,525 adults who participated in the US National Health and Nutrition Examination Survey (NHANES) between 2007 and 2018. Participants also completed the PHQ-9 questionnaire, a standard tool used to assess the severity of depressive symptoms.

About 8% of participants reported depressive symptoms. Diet types were grouped into four categories:

• Calorie-restrictive diets
• Nutrient-restrictive diets (low in fat, sugar, salt, fibre, or carbs)
• Established diets (such as diabetic diets)
• No specific diet

The majority—87%—were not following any specific diet. Only 8% reported being on a calorie-restrictive diet, and even fewer followed nutrient-restrictive (3%) or established (2%) dietary plans.

Key Findings: Dieting and Depressive Symptoms

The results showed that people on calorie-restrictive diets had slightly higher PHQ-9 depression scores than those not on a diet. The differences were more significant among overweight individuals and men.

Overweight individuals following calorie-restrictive diets had PHQ-9 scores 0.46 points higher.

Nutrient-restrictive diets led to a 0.61-point increase in depressive scores in the same group.

Men on nutrient-restrictive diets had higher cognitive-affective symptoms (thoughts and feelings linked to depression) compared to women.

All three diet types were associated with higher somatic symptoms (physical symptoms linked to emotional distress) in men.

Possible Explanations and Limitations

Researchers noted that participants might have inaccurately reported or classified their diets. Unlike clinical trials, real-life calorie-restricted diets often lack adequate nutrients, leading to deficiencies that could affect mental health.

The researchers suggest that poor nutrient intake, weight cycling, and physiological stress might contribute to the link between dieting and depression. They also highlight the role of nutrients like omega-3 fatty acids and vitamin B12 in supporting brain function—nutrients that may be lacking in restrictive diets.

While the effects seen in the study were modest, the findings add to growing concerns about the mental health impact of restrictive diets. Experts stress the need for well-designed studies that accurately assess diet and mental health links, particularly among vulnerable groups.
