What is A2 milk?
Suvarna Sawant, Chief Dietitian & HoD, Clinical Nutrition and Dietetics at Nanavati Max Super Speciality Hospital in Mumbai, told HT Lifestyle about its protein composition. He said, 'A2 milk contains only A2 beta-casein protein, unlike regular milk, which has both A1 and A2 variants. It is derived from specific cow breeds like Gir and Sahiwal.'
Ravin Saluja, Director at Sterling Agro Industries Ltd, further added to the explanation about the milk's source, elaborating, 'Traditional cow's milk contains two types of B-casein proteins, A1 and A2. Most modern breeds, like Holsteins, produce a mixture of both. A2-only milk, however, is sourced from cows genetically bred to produce only the A2 variant.'

This milk, with a specific type of protein composition, offers digestive relief to some people. But Dietician Suvarna reminded that it is not lactose-free, meaning it is not for lactose-intolerant people, but for those who suffer from mild digestion discomfort from regular milk.
The dietician added, 'Some individuals may find it easier to digest, but it is important to note that A2 milk is not lactose-free. Individuals with protein deficiency, who cannot digest the normal cow milk but are not lactose intolerant, are ideal candidates for A2 milk.'
Ravin, based on market insights, also highlighted that consumers with digestive sensitivities, fitness enthusiasts, and health-conscious families increasingly prefer A2 milk for relatively better digestibility. He said, 'Those experiencing bloating or discomfort from regular milk may find A2 easier to digest. Likewise, A2's clean protein profile aids in muscle recovery without gut upset. And parents of toddlers or elders also seek natural, wholesome nutrition, and are snapping up A2 variants.'
Growth in market
Ravin shared that A2 milk's growth has seen a momentum, a growing preference among consumers, especially because of ease of digestion. He said, 'In India, market size surged to $416 million in 2024, with a projected CAGR of 19.7%, inspiring interest in premium dairy. A greater consumer shift toward wellness, digestion-friendly foods, and clean labels is a key market driver.'
From regular milk, taste-wise, A2 milk isn't much different, as Ravin noted, 'Taste isn't compromised. A2 milk tastes very similar to conventional milk, as any subtle differences stem more from breed and feed than the protein type.'

Do you skip breakfast often? Gastroenterologist shares 4 ways it can affect your digestion
Many people tend to skip breakfast, whether to lose weight, save time, or simply because they don't feel hungry in the morning. However, consistently missing this important meal can have serious effects on your overall health. Also read | What is the 'ideal' breakfast? Study reveals how you should consume your first meal of the day Consistently missing breakfast can have serious health effects.(Freepik) In an interview with HT Lifestyle, Dr Surakshith TK, senior consultant-gastroenterology and hepatology, Fortis Escorts, Okhla, said, 'Not eating breakfast is unhealthy for digestion as it slows down metabolism, stimulates the stomach to produce more acid, damages the health of the gut, and leads to excessive consumption of food during the day. For improved digestive health and general well-being, a person should begin the day with breakfast.' 1. Slows down metabolism If you do not have breakfast, your body has no fuel after having rested for an entire night. Your metabolism, thus, slows down. Eating a balanced breakfast kick-starts your metabolism, maintains your blood sugar level steady, and facilitates smooth digestion throughout the day. If you miss breakfast, your body enters starvation mode, and it conserves energy rather than burning it, thus slowing down digestion. Skipping breakfast can increase acid production.(Freepik) 2. Increases acid production Skipping breakfast can increase the amount of acid in the stomach. This excess acid can cause pain and even diseases like acid reflux or gastritis. Since the body is not receiving food in the morning, your stomach continues to produce acid anticipating a meal, which can irritate the stomach lining and esophagus. This pain can disrupt your meal in the second half of the day. Also read | World Nutrition Day: Why a balanced breakfast is key to a healthy day 3. Upsets gut health Your digestive system functions best when it's in a routine, too. Missing meals, especially breakfast, also breaks the regular rhythm of digestion. The gut needs to have an ongoing supply of food so that everything continues to move along and constipation doesn't catch up with you. Missing breakfast makes you balloon, have indigestion, and experience irregular bowel movements as your digestive system weakens. 4. Makes you overeat later Going without breakfast would leave you hungry during the afternoon, and that might lead to overeating during lunch or dinner. This immediate intake of food usually irritates the digestive system and causes bloating, indigestion, or discomfort. Daily intake of small portions over the course of a day, starting from breakfast, is required to maintain the digestive system under control.

Hair fall attack in monsoon: Hair transplant surgeon explains why it happens and what you can do about it
Many people notice increased hair loss during the monsoon season. While it may seem alarming, this is often caused by factors like high humidity, stress, and seasonal illnesses. The condition, known as telogen effluvium, leads to temporary hair shedding, particularly during the rainy months. Also read | Facing sudden hair loss? Dermat explains if it's hair fall attack or hair cycle reset Telogen effluvium leads to temporary hair fall.(Freepik) In an interview with HT Lifestyle, Dr. Gaurang Krishna, hair transplant surgeon and co-founder, MedLinks said, 'Humidity causes your scalp to stay damp longer, encouraging fungal growth, dandruff, and clogged hair follicles. Add in stress, junk food, and erratic sleep, and your hair decides to take a short vacation.' What is telogen effluvium? 'This isn't permanent hair loss. Your strands are falling from the root, not with the root. That means your hair follicles are intact; they're just in a resting phase, and with the right care, they'll bounce back,' said the surgeon. Know how to reduce hair loss in monsoon.(Unsplash) Do you wash your hair daily? One of the common complaints that people have is that they shed more hair when they wash their hair daily. Dr Gaurang Krishna explained why it happens, 'Over-washing or using harsh shampoos strips your scalp of natural oils, while under-washing clogs pores with sweat and pollution. The sweet spot? 2-3 times a week with a mild, sulfate-free shampoo. If dandruff is a regular visitor, switch to one with salicylic acid or anti-fungal agents.' Also read | Is stress one of the main triggers of hairfall? 8 tips to protect your hair Monsoon hair care guide: Keep it clean: Your scalp, not your conscience. Wash regularly but gently. Oil smartly: Oiling is nourishing, but only on a clean scalp. Otherwise, you're feeding the fungus. Be protein-wise: Hair = keratin = protein. Load up on paneer, dals, tofu, eggs, and nuts. Hands off wet hair: Don't comb or tie hair when it's soaking. Think wet spaghetti, it snaps! Keep cool: Stress is a major hair fall trigger. Try yoga, cricket, or even poker (unless you lose too much).

National Bone and Joint Day 2025: Orthopaedic surgeon warns of rising joint issues in young adults, shares precautions
National Bone and Joint Day: August 4th is celebrated as National Bone and Joint Day in India. This day promotes awareness about musculoskeletal and joint disorders, along with their prevention, diagnosis, and management. Joint pain is very common in the youth these days.(Shutterstock) ALSO READ: National Bone and Joint Day 2025: Doctor shares 7 mistakes employees in desk-bound jobs make that damage knee joints In observance of the day, let's understand why joint issues are no longer the concern of older adults, as the youth today also increasingly seem to have joint problems. Dr Amyn Rajani, Consultant Knee, Shoulder and Hip Surgeon, Breach Candy PD Hinduja and Saifee, shared with HT Lifestyle that the age range of 30 to 50 has seen a rise in degenerative joint conditions." Elaborating more on this, the doctor said, " Today, we're seeing younger adults – particularly in the 30–50 age range –with degenerative joint conditions, a steep rise in sports and gym-related injuries, more cases of postural syndromes as well as repetitive stress injuries due to incorrect fitness routines, gadget overuse and work-from-home setups. Conditions like early-onset osteoarthritis and femoro-acetabular impingement (FAI) in the hip are becoming more visible in urban outpatient clinics. These weren't on our radar 15 years ago.' Alarmingly, musculoskeletal disorders are becoming increasingly common, affecting a concerning portion of the population. Dr Rajani spoke, "Nearly 1 in 5 Indians suffers from some form of musculoskeletal disorders such as osteoarthritis, rheumatoid arthritis, osteoporosis, ligament and meniscus injuries, frozen shoulder, low back pain, and slipped discs.' To protect your joints from long-term damage, especially given how common these issues are among Indians, you may need a multifaceted approach that includes awareness, recognising early warning signs, and adopting the right preventive measures. Dr Amyn Rajani shared a guide, outlining three key essentials, which include reasons, symptoms, and prevention: Reasons for musculoskeletal disorders Obesity increases risk of poor joint health.(Photo: Adobe Stock) Prolonged sitting and lack of core strength can lead to mechanical back pain and disc issues. Obesity and improper exercise, such as excessive squats or running on hard surfaces, can result in knee pain and early cartilage wear. Shoulder impingement and rotator cuff issues are related to gym injuries and poor posture. Sports injuries like ACL and meniscus tears arise from recreational or competitive activity without proper conditioning. 5 early signs of joint trouble 1. A grinding or cracking sound when moving your joints 2. Stiffness in the morning that lasts more than 15–20 minutes 3. A feeling of discomfort after activity or long rest 4. Mild swelling or puffiness around the joint 5. A sensation that your joint is unstable or might give way, especially in the knees 3 Lifestyle changes for better joint health Regular strength training helps to keep your joints healthy.(Freepik) 1. Include strength training with low-impact cardio Include strength training about 2 to 3 times a week. This helps build the muscles that support your joints, especially around your knees, hips, and shoulders. Pair that with low-impact cardio like swimming, cycling, or brisk walking about 4 to 5 times a week to keep your joints moving and your weight in check. 2. Run with proper preparation Running on hard surfaces like concrete isn't the best for your knees. Over time, the repeated impact can cause wear and tear, especially if you're not using proper footwear or running form. Try alternating with softer surfaces like grass, trails, or a treadmill, and consider mixing in other activities. 3. Dietary adjustments To support joint health, make sure you're getting enough calcium and vitamin D. Calcium-rich foods: Calcium-rich foods include dairy like milk, cheese, and yoghurt, leafy greens such as spinach and kale, almonds, tofu, and fortified cereals. Calcium-rich foods include dairy like milk, cheese, and yoghurt, leafy greens such as spinach and kale, almonds, tofu, and fortified cereals. Vitamin D-rich foods: Vitamin D helps your body absorb calcium. You'll find it in fatty fish like salmon and mackerel, egg yolks, fortified milk and orange juice, and with about 10 to 15 minutes of sunlight each day.
