Luke Coutinho revealed that the "sunshine vitamin" functions more like a hormone - influencing almost every cell in the body, including those involved in insulin sensitivity, sex hormone regulation (estrogen, progesterone, testosterone) and even neurotransmitter production.
In the video, he explains, "Low vitamin D3 affects people from the time they're kids, teenagers, adults and senior citizens in many, many ways. It's not just about brittle bones. It's not just about low energy levels. Vitamin D3 is a sex hormone playing a massive role in your overall hormonal health. Your progesterone, your estrogen, your testosterone and even your insulin sensitivity."
Luke Coutinho continues, "You will notice that in patients who have insulin resistance, insulin sensitivity, they always have low vitamin D3 levels. And by correcting that level through sunlight, through food, and mainly supplementation."
In the caption, the lifestyle guru further explains that low D3 levels during the formative years in children and teens can affect bone growth, mental health, mood swings, height and hormone balance. Additionally, he mentions that low levels in adults give rise to autoimmune conditions, chronic fatigue, anxiety, hair fall, infertility and even metabolic syndromes.
According to Luke, "a casual stroll in the morning sun may no longer be enough," as he shares, "The humans have messed up our climate. We've messed up our ozone layer. We don't even have the right amount of UVB rays hitting our skin, which is the magic sunshine that helps us with vitamin D3. So, yep, you're going to have to go to your doctor, kids, teenagers, and senior citizens, and make sure that you supplement the right way."
He also writes, "Before you invest in exotic supplements or strict diets, look at your basics: D3, B12, Iron, Magnesium, Thyroid and Gut health markers. Your body doesn't thrive on complexity-it thrives on consistency with fundamentals."
Luke Coutinho further mentions that the optimal reference range for D3 should be 30 to 100, and the best is within the range of 70 to 80 ng/mL (within a safe range of 30-100), that too under medical supervision. The celebrity lifestyle expert also advises that one should not overdo it on D3, as this can become extremely toxic to the body, especially the kidneys and other bodily organs. He clarifies, "The patients who come to us with critical levels, their D3 is at 5, 6 and 7. Within 10 to 15 days of starting to push their D3 up, most of their symptoms start to get better. You cannot ignore the basics."
In his concluding note, Luke mentions, "D3 is basic, but ignoring it is a big mistake."

Chef Ranveer Brar says never do this while blanching spinach if you want to preserve its colour and texture: ‘Always...'
Blanching spinach may seem like a simple kitchen task, but if you've ever ended up with dull, overcooked greens instead of that vibrant restaurant-style palak, you're not alone. The good news? Celebrity chef Ranveer Brar has just the solution. In his July 22 Instagram post, he breaks down the art of blanching spinach to perfection, ensuring it retains its bright green colour, fresh taste, and maximum nutrition. (Also read: Chef Ranveer Brar shares simple tips to get soft, perfect dough for rotis and pooris: 'The more you stretch it…' ) Master the art of blanching spinach with chef Ranveer's essential cooking tips. What are the dos and don'ts of blanching spinach In his post, Chef Ranveer says, "If you want to ruin the colour of your spinach, just add vinegar to the water while boiling. That's a surefire way to mess it up." But if you want to do it right, he suggests, 'To maintain the vibrant green colour of palak, add a pinch of baking soda to the boiling water. It helps retain the freshness and bright hue.' Once the water is boiling, he adds the palak in but with a warning. "If you don't keep cold water ready while boiling the spinach, and skip transferring it immediately to cold water afterwards, the colour will turn almost black." And here's one tip most people don't know: "Never cover spinach while cooking it. If you do, the temperature rises more than necessary, and that intense heat can darken the colour. Always cook it uncovered to preserve that beautiful green," says Chef Ranveer. Nutritional benefits of spinach Palak, or spinach, is a powerhouse of nutrients packed with iron, calcium, magnesium, and vitamins A, C, and K. It's rich in antioxidants, supports immunity, boosts bone health, and promotes healthy skin and hair. Low in calories and high in fibre, palak is also great for digestion and weight management.

"Body Sacrifices Own Tissue": Gaza Doctor On The Impact Of Starvation
Gaza is now effectively starving. A doctor inside the besieged enclave has now delivered a chilling breakdown of how starvation shuts down the human body, from initial hunger pangs to the collapse of vital organs. Dr Mohammed Abu Mughaisib, deputy medical coordinator for Medecins Sans Frontieres (Doctors Without Borders), explained that in the first six to 24 hours without food, the body begins burning through its glycogen reserves. These are stored sugars that serve as emergency fuel. By day one to three, once glycogen is depleted, the body switches to using fat, converting it into ketones to keep the brain functioning. At this point, the body enters a state of full survival mode. From two to five days, the toll becomes severe. The body begins breaking down its own muscle tissue, including vital organs like the heart, in a desperate attempt to stay alive. "The body sacrifices its own tissue just to survive," Dr Mughaisib explains. "This is when children stop crying." Dr Mughaisib is not only describing starvation, he is living it. "For the past months, I have been surviving on one meal per day," he said. "And in the last few days, I have even had only one meal every two days. Not because I cannot afford it, but because there is nothing to buy. The markets are completely empty." Recent reports detail how health workers are collapsing from hunger while transporting patients. Ambulance drivers are starving. Children are dying. "We are expected to save lives while our own are slowly being consumed," the doctor said. "This is not just about hunger, but about the slow destruction of life, ability, and humanity." "This has to stop. To use food, water, and aid as weapons in this world, it's not acceptable at all," he added. View this post on Instagram A post shared by Médecins Sans Frontières (MSF) (@doctorswithoutborders) Israel's war on Gaza has now entered its 21st month, and the humanitarian crisis is worsening by the day. Since October 7, 2023, close to 60,000 Palestinians have been killed and over 142,500 injured, according to Gaza's Health Ministry. At least 17,400 children are among the dead, one of the highest child death tolls. UN agencies warn that Gaza is now on the brink of famine. Over 470,000 people, including 71,000 children under five, are starving. Israel's full blockade, in place since March 2, has cut off nearly all access to food, medicine, fuel, and aid. More than 1,060 people have been killed trying to reach food distribution points. UN and human rights organisations continue to accuse Israeli authorities of using starvation as a weapon, a claim Israel rejects, arguing administrative challenges and Hamas interference are the cause.

Look beyond salads for fibre: Gastroenterologist suggests top 10 high fibre foods you should include in your diet
Fibre may be best known for its ability to prevent or relieve constipation. But foods that are rich in fibre can have other good effects as well, ranging from aiding weight loss, lowering the risk of heart disease and some types of cancer, helping maintain weight, and more. When it comes to fibre intake, we limit ourselves to salads when there is a world of options available in our kitchens. Check out the list. (Shutterstock) Also Read | Gastroenterologist shares 4 bowel cancer symptoms to look out for: Persistent bloating to night sweats However, often, when it comes to fibre intake, we limit ourselves to salads when there is a world of options available in our kitchens. In an Instagram post shared on July 25, Dr Saurabh Sethi, MD, MPH, board-certified gastroenterologist, hepatologist, and interventional endoscopist trained at AIIMS, Harvard and Stanford, shared the top 10 high-fibre foods that go beyond salads. Let's find out what they are: Top 10 high fibre foods suggested by a gastroenterologist Here are the top 10 foods Dr Sethi recommended: Lentils Chickpeas Roasted chanas Tempeh Sabja seeds (basil seeds) Psyllium Husk Barley Oats Okra or bhindi (lady finger) Figs (dried or fresh) How much fibre should you consume? According to the American Heart Association Eating Plan, eating a variety of fibre sources is the key to good health. Total dietary fibre intake should be 25 to 30 grams a day from whole foods, not supplements. Currently, dietary fibre intakes among adults in the United States average about 15 grams a day. That's about half the recommended amount. Meanwhile, Indians consume just 15 grams of it when the Indian Council of Medical Research (ICMR) recommends a daily fibre intake of 25-40 grams for adults: around 25 grams for women and around 38 grams for men.
