What is umami? Explaining the mysterious 'fifth taste'
You know that burst of flavour you experience when you take a bite of certain savoury foods such as meat, fish, mushrooms or miso? That sensation of 'whoa, that is just delicious'?
In all likelihood, you are tasting umami.
Umami, which translates to 'delicious savoury taste', was identified as a distinct flavour in 1908 by Japanese chemist Kikunae Ikeda. It's now recognised as the fifth taste, joining sweet, salty, bitter and sour.
The concept of this fifth taste has been embraced in the East for a long time, before it had an official name. But it's still a relatively new idea to many home cooks in the West.
If you've ever wondered why sprinkling Parmesan on your pasta made it just so much more satisfying, why the exterior of a roasted pork shoulder has so much flavour, why miso soup tastes so luxurious, why bacon is so freaking delicious, why an anchovy-based Caesar salad dressing makes you want to wriggle with joy, why caramelised onions have so much depth – the answer is umami.
You can get rich umami flavours by cooking down your tomatoes.
Umami flavour comes from glutamate, a common amino acid or protein building block found in many foods. The most familiar is monosodium glutamate, or MSG. In the United States, it was once believed that MSG wasn't good for you, but it's now generally recognised as a safe addition to food. Many Asian chefs have worked to reintroduce MSG into daily cooking.
Foods rich with umami flavour include:
Aged cheeses: Blue cheese, gouda and cheddar are some of the most umami-packed cheeses due to the breakdown of proteins that takes places during the ageing process. Parmesan cheese is widely recognised as an 'umami bomb'.
Tomato products: The more cooked down, the more concentrated the umami – think tomato paste, sun-dried tomatoes and ketchup.
Mushrooms: In particular, shiitake, oyster and portobello mushrooms. Also, make use of dried mushrooms.

Meat and meat broths: Roasted and grilled meats are examples of umami richness. A roasted chicken, pan-seared steak. Cured meats like prosciutto and bacon are also umami powerhouses. So are ramen, udon soup and other foods made with rich savoury broths.
Fish and seafood: Especially varieties like sea urchin, shrimp and scallops. You will also find high levels of umami flavour in fish and fish broths, especially little oily fish like sardines and anchovies.
Bonito flakes: These tissue-thin, fluffy shards of cooked and dry-smoked tuna are used as the base of dashi, a seasoning blend at the base of much Japanese cooking. Dashi also usually includes shiitake mushrooms and kombu (seaweed).
Soy sauce or shoyu: One of the pillars of umami flavour in Asian cooking. Fermentation breaks down the proteins in the soybeans and wheat used to make soy sauce into amino acids, glutamic acid in particular. Tamari is a gluten-free version of this condiment.
Fish sauce: This is another source of umami, used often in South-East Asian cooking. The basic ingredients are anchovies and salt. The salt pulls out the liquid from the fish and creates a dark, potent amber sauce. This is one of the reasons that Thai, Vietnamese and Filipino food, to name a few, taste so distinctively and pungently savoury.

Vegetarians and vegans might think that elusive fifth taste is hard to achieve without meat or other animal products, but there is much good news! The following are some options for vegans.
Seaweed: Another big source of umami (and not coincidentally the other main ingredient in dashi).
Yeast enhancers and spreads: Umami is the leading flavour note of Marmite and nutritional yeast.
Miso paste: Made from fermented soybeans, miso paste is high in umami. It doesn't matter whether you are using white miso, brown rice miso, red miso or yellow miso.
Now that you know what you're tasting, you'll be looking for ways to incorporate more of this fifth dates into your cooking. It's truly as easy as knowing what ingredients to reach for! – By KATIE WORKMAN/AP

Puberty occurring at an unusually early age
Sara was only seven when her mother noticed something unusual – her daughter had started developing breasts and even had her first period. This caught the family by surprise. Isn't puberty supposed to start later? Worried, they came to see me. Sara's story is one many parents might find unfamiliar but is important to understand. When children start puberty too early – before age eight in girls and before age nine in boys – it's called precocious puberty. What happens during puberty? Puberty is a time of big changes. The brain tells the body to start producing hormones that help children grow taller, develop breasts or testicles, grow body hair, and eventually become capable of reproduction. The main hormone messenger in this process is a chemical in the brain called gonadotropin-releasing hormone (GnRH). It signals the pituitary gland (a small gland at the base of the brain) to release two key hormones: luteinising hormone (LH) and follicle-stimulating hormone (FSH). These in turn stimulate the ovaries in girls and the testes in boys to produce estrogen and testosterone, the hormones responsible for the visible changes of puberty. Normally, girls start puberty between eight and 13 years, while boys begin between nine and 14 years. But when this process begins too soon, children face unique physical and emotional challenges. When precocious puberty strikes, boys might feel pressured to behave in a more mature way than they're ready for. — Pixabay Signs to watch for How do you know if your child may be entering puberty early? Here are some common signs: In girls: > Breast development before the age of eight > Menstrual bleeding before the age of 10 > Rapid growth or 'growth spurts' > Pubic or underarm hair > Acne or oily skin > Body odour similar to that of a teenager. In boys: > Enlargement of the testicles or penis before age nine > Deepening of the voice > Muscle growth > Facial, underarm, or pubic hair > Acne and body odour. In both boys and girls, a noticeable increase in height over a short period may be one of the first signs parents pick up on. Sometimes these signs can be subtle at first. If you're unsure, speak to your child's doctor. Why does early puberty happen? In most girls, early puberty is due to the brain starting the hormone process too early. This is called central precocious puberty (CPP), and in many cases, there is no identifiable cause – it just happens. However, if the onset is very young before six years or in boys, it is likely to be caused by a medical issue, such as a problem in the brain, a tumour, or another hormonal disorder. Less commonly, precocious puberty can be peripheral – meaning the hormone changes start outside the brain. This could be due to problems with the adrenal glands, ovaries, or testes, and is not triggered by the usual brain hormones. Other known factors that may play a role in triggering early puberty include: > Brain abnormalities or tumours, especially in very young children > Previous radiation or trauma to the brain > Congenital conditions, such as hypothalamic hamartoma > Obesity, which is increasingly recognised as a contributing factor > Family history of early puberty > Environmental exposures to hormone-disrupting chemicals. What are endocrine disruptors? Parents should be aware of endocrine-disrupting chemicals (EDCs). These are substances that can interfere with the body's hormone systems. Some are found in plastics especially bisphenol A (BPA), cosmetics, fragrances, pesticides and even some foods e,g, plant-based estrogen known as phytoestrogen. For example, certain essential oils like lavender and tea tree oil have been linked – though not conclusively – to hormone effects in children. Creams or supplements bought over the counter or online may also contain undisclosed hormones. While the science and evidence is still evolving, it's best to reduce unnecessary exposure to products that may contain hormones or hormone-like compounds, especially in young children. How is early puberty evaluated? If your child is showing early signs of puberty, the next step is to consult a paediatric endocrinologist – a doctor who specialises in hormone issues in children. Here's what you can expect during an evaluation: > A detailed medical and family history, including growth patterns, timing of puberty in parents and any medications or exposures > A physical examination to assess the stage of puberty and growth rate > Blood tests to measure hormone levels (LH, FSH, estrogen or testosterone, and other related hormones) > Bone age X-ray of the left hand and wrist to see how much a child's bones have matured > Pelvic ultrasound in some girls to assess the uterus and ovaries, or testicular ultrasound in boys if needed > Pituitary MRI in certain cases (especially in boys or girls under six years, or those with rapid progression) to look for brain abnormalities. What problems can early puberty cause? One major concern with precocious puberty is shorter adult height. Children grow quickly at first, but their bones also mature faster. This can lead to the growth plates closing earlier than usual, limiting final height. There are also emotional and psychological challenges. Children who develop earlier than peers may feel different, embarrassed or self-conscious. Girls may struggle with body image or unwanted attention. Boys might feel pressured to behave in a more mature way than they're ready for. These feelings can affect self-esteem, social development and even school performance. Can early puberty be treated? Yes! The good news is that precocious puberty can be managed effectively. The main treatment for central precocious puberty is with GnRH analogues – medications that 'switch off' the puberty hormones by blocking the signals from the brain. These medications are usually given as intramuscular injections, typically once a month or every three to six months, depending on the preparation used. These medications are generally safe and well-tolerated, and once they are stopped (usually around the normal age of puberty), the body resumes puberty naturally. Side effects such as sterile abscess at the injection sites are reported but uncommonly. Treatment helps preserve height potential and gives children more time to grow physically and emotionally before entering adolescence. Any underlying causes or contributing factors must also be addressed. A paediatric endocrinologist considers treatment based on: > The child's age > How fast the puberty is progressing > Bone age and predicted adult height > The child's emotional readiness and how they're coping. Sara's journey Sara began treatment soon after her diagnosis. Her hormone levels were consistent with early puberty, and her bone age showed advanced maturity compared to her actual age. With three-monthly injections and regular follow-up, her puberty progression slowed, and her growth pattern stabilised. More importantly, she had the time to adjust emotionally and her confidence returned. With the support of her family, Sara started feeling like a kid again. So, if you suspect your child might be going through puberty too early, trust your instincts. Seek medical advice early – because early diagnosis can make a big difference in your child's growth, emotional health and long-term well-being. Remember: > Not all early signs mean your child has precocious puberty or needs treatment, but it's worth getting checked > Treatment is available and effective > Support from parents and clear information can help your child feel safe and understood. And finally, be mindful of the products your child is exposed to – avoid unnecessary fragrances, creams, oils or supplements that may contain hormone-like substances. With awareness, early action, and the right care, children with precocious puberty can go on to thrive – just like Sara.

Annual births fall to another record low in Japan as population emergency deepens
TOKYO: The number of newborns in Japan is decreasing faster than projected, with the number of annual births falling to another record low last year, according to government data released on Wednesday (June 4). The Health Ministry said 686,061 babies were born in Japan in 2024, a drop of 5.7% on the previous year and the first time the number of newborns fell below 700,000 since records began in 1899. It's the 16th straight year of decline. It's about one-quarter of the peak of 2.7 million births in 1949 during the postwar baby boom. The data in a country of rapidly aging and shrinking population adds to concern about the sustainability of the economy and national security at a time it seeks to increase defence spending. Prime Minister Shigeru Ishiba has described the situation as "a silent emergency' and has promised to promote more flexible working environment and other measures that would help married couples to balance work and parenting, especially in rural areas where family values tend to be more conservative and harder on women. Japan is one of a number of east Asian countries grappling with falling birth rates and an ageing population. South Korea and China have fought for years to encourage families to have more children. Also on Wednesday, Vietnam scrapped decades-old laws limiting families to two children in an effort to stem falling birth rates. The Health Ministry's latest data showed that Japan's fertility rate - the average number of babies a woman is expected to have in her lifetime - also fell to a new low of 1.15 in 2024, from 1.2 a year earlier. The number of marriages was slightly up, to 485,063 couples, but the downtrend since the 1970s remains unchanged. Experts say the government's measures have not addressed a growing number of young people reluctant to marry, largely focusing on already married couples. The younger generation are increasingly reluctant to marry or have children due to bleak job prospects, a high cost of living and a gender-biased corporate culture that adds extra burdens for women and working mothers, experts say. A growing number of women also cite pressure to take their husband's surname as a reason for their reluctance to marry. Under Japanese law, couples must choose a single surname to marry. Japan's population of about 124 million people is projected to fall to 87 million by 2070, with 40% of the population over 65. - AP
