Sugar Lights Up the Brain But Not Always in a Good Way
Your brain loves sugar but too much of it can cause problems. Here's what really happens when you eat sugary food or drinks.
Glucose is your brain's main fuel. After eating sugar, your brain gets a fast energy spike making you feel alert and awake (temporarily).
1. Instant Energy Boost
Sugar triggers dopamine—the 'feel good' chemical. It lights up brain reward centers, which is why sugar can feel addictive.
2. Dopamine Rush
Once the sugar rush fades, your blood sugar crashes. This can lead to irritability, fatigue, and anxious feelings.
3. Mood Swings
Too much sugar can disrupt how brain cells communicate. You may feel foggy, distracted, or have trouble focusing.
4. Focus & Brain Fog
Diets high in sugar are linked to weaker memory and learning. Over time, sugar may shrink memory-related brain areas like the hippocampus.
5. Memory & Learning
High sugar intake increases brain inflammation and raises the risk of depression, anxiety, and diseases like Alzheimer's.
6. Long-Term Impact
Sweet, but at a Cost
Sugar isn't the enemy but too much can affect how your brain works. Fuel your mind with balanced meals and keep sugar as an occasional treat.

Alzheimer's disease: Common herbs used in the kitchen could help slow down the progression of the disease, study finds
Imagine a common sprig of rosemary or sage gracing your roast chicken! Now, imagine that this modest herb may harbor a powerful ally in the fight against Alzheimer's. Yes, that's right. Tired of too many ads? go ad free now Recent breakthroughs spotlight a compound called carnosic acid, an antioxidant and anti-inflammatory powerhouse present in these kitchen staples. In its natural form, carnosic acid is unstable, yet innovative science has transformed it into a stabilized prodrug, diAcCA, capable of crossing the blood-brain barrier and selectively activating in damaged, inflamed brain cells. While still in the pre-clinical stages, this discovery lights a spark of hope, hinting that everyday herbs might play a role in slowing, or even preventing, cognitive decline. What does the study say? In a recent study published in the journal Antioxidants, researchers from the Scripps Research Institute discovered a compound called carnosic acid – found in rosemary and sage – with impressive antioxidant and anti-inflammatory properties. They suggest that this compound could be beneficial for neurodegenerative disorders like Alzheimer's. Researchers Piu Banerjee and Dr. Stuart Lipton shared their findings with Fox News Digital. They said, 'In this study, we observed that administering this drug to mice that had advanced Alzheimer's-like disease significantly improved the number of neurons, as well as the number of synapses or connections between the brain cells.' They also noted, 'It reduced inflammation caused by current anti-amyloid antibody therapies and improved learning and memory behavior in the mice that received the drug.' Banerjee explained that carnosic acid is a 'prodrug,' meaning it's inactive until it enters the body, where it gets activated by oxidative and inflammatory stress. Tired of too many ads? go ad free now 'It specifically targets cells undergoing oxidative and inflammatory stress, without affecting healthy, normal brain cells,' she added. This makes it a safer option for treatment. The researchers believe carnosic acid might help reduce inflammation in aging brains. However, they urge caution. Courtney Kloske, director of scientific engagement for the Alzheimer's Association, stressed that while studying mice helps us understand the disease, we really need to conduct human studies for a complete picture. 'These findings are intriguing, but more research is needed to see how these compounds affect people living with or at risk for Alzheimer's,' she advised. Banerjee and Lipton also noted that just cooking with sage and rosemary won't deliver the same anti-inflammatory benefits. "Critically, one cannot take sufficient herbs safely to produce the same effect as our new drug,' Banerjee explained. Kloske added, 'At this point, no one should consume these herbs or carnosic acid to prevent or treat Alzheimer's or other cognitive impairments.' Origins and key compound: Carnosic acid in rosemary and sage Rosemary (Rosmarinus officinalis) and sage have both storied reputations—ancient scholars hung rosemary in their robes to boost memory. Modern research confirms that carnosic acid, alongside carnosol and rosmarinic acid, provides potent antioxidant and anti-inflammatory effects that can reach the brain. These compounds activate the Nrf2 pathway, which spurs the production of endogenous enzymes that combat oxidative stress – one of Alzheimer's disease's key drivers. From kitchen to Lab: Creating diAcCA Carnosic acid's instability limited its therapeutic potential – until researchers at Scripps created diAcCA, an acetylated prodrug version. When consumed, diAcCA converts into its active form in the gut, crossing into the bloodstream and, crucially, the brain. In mouse models mimicking Alzheimer's (5xFAD strain), three months of diAcCA treatment led to restoration of memory and learning to near-normal levels, increased synaptic density in hippocampal circuits, and reduced neuroinflammation and diminished amyloid-β and phosphorylated tau accumulation. These results were consistent across behavioral tasks, histology, and biochemistry, with no observed toxicity. Mechanisms at work: A multi-front attack diAcCA (and its metabolite carnosic acid) appear to combat Alzheimer's via several reinforcing mechanisms: Antioxidant defense: Activates Nrf2, turning on protective genes that tackle oxidative stress and stabilize cell redox balance. Anti‑inflammatory action: Blocks cytokine release (IL-1β, IL-6, TNF‑α) and inhibits inflammasome activation, reducing harmful microglial activity. Neurotrophic support: Boosts nerve growth factor, BDNF, and synaptic resilience. Cholinergic enhancement: Rosemary's 1,8‑cineole component inhibits acetylcholinesterase, helping sustain acetylcholine levels vital for memory. Reduced neurotoxic proteins: Helps clear amyloid‑β and tau aggregates via synaptic and inflammatory pathways. The future ahead: While diAcCA hasn't yet been tested in people, several encouraging signals emerge: FDA classifies carnosic acid as 'Generally Recognized as Safe', which may speed early‑stage trials. diAcCA appears well tolerated in mice, with even digestive system benefits, while smaller human trials using rosemary/sage extracts showed improved cognitive speed and memory performance in older adults. Meta‑analyses of animal studies reflect moderate‑to‑strong cognitive gains from rosemary extract. Banerjee expressed hope for the future, stating, 'I hope our drug will start human clinical trials soon. If it proves to be effective, it will be a great new drug for those suffering from Alzheimer's. We are cautiously optimistic for its success in human clinical trials!'

Endocrinologist Dr. Ambrish Mithal on the happy side-effects of weight-loss drugs
New-age weight-loss drugs are exploding the pharmaceutical market, offering better results than traditional medicines. Top endocrinologist Dr. Ambrish Mithal deconstructs the many facets, including side-effects, of these GLP-1 drugs in his recently published book The Weight Loss Revolution, in an episode of India Today's said that while the GLP-1 field -- drugs that belong to the class of GLP-1 targeting the same hormone in the body -- is just beginning to explode, there'll be many newer drugs with less and less side effects and easier to most cases have shown muscle loss as a prominent result of using GLP-1 medications like tirzepatide or semaglutide, Dr. Mithal explains that losing muscle is an accompanying factor to weight loss. "In the long run, if you're not following a healthy diet, you will end up with significant muscle loss. And this is not because of the weight-loss drugs. Whenever we lose weight, we also lose muscle. If you lose 10 kg, you've lost 2-3 kg of muscle. Now, if you want to preserve that, you have to ensure adequate protein and fibre in your diet. Along with that, you have to make sure that you're exercising regularly and that exercise should include strength training," Dr. Mithal also shared what many people experience loose skin after taking these medicines. "When you lose weight rapidly, you lose subcutaneous fat. Particularly in older people where skin tends to sag anyway. If you suddenly lose weight, don't hydrate yourself well, not eating the right kind of balanced diet, then you get that little sagging on the face which people have started calling Ozempic face. Before these drugs came into the market, anyone we put on a very strict diet or someone who had bariatric surgery would see similar results," he gastrointestinal side-effects, nausea, and vomiting, Dr. Mithal addressed concerns about thyroid cancer, highlighting that there's no evidence to link the also explained the "happy side-effects" of GLP-1 medications. Besides growing body of evidence suggesting how semaglutide is linked to Alzheimer's disease, Dr. Mithal said that the benefits of the drugs are moving beyond weight loss."The evidence that they might be helping Alzheimer's by helping obesity in the brain may actually be very exciting, and even for cardiac health, Parkinson's disease. Cardiac events are reduced. Fatty liver is reduced. Kidney disease progression is reduced. But the brain effects are particularly fascinating. Sleep apnea has also gone down," he said, adding that the drugs have also helped improve fertility outcomes in women with PCOS (Polycystic Ovary Syndrome).Currently, most GLP-1 drugs are injectable and expensive, limiting their access in India. However, new formulations and more research are on the way. Novo Nordisk's Wegovy and Eli Lilly's Mounjaro, two blockbuster fat-busting medicines, are set to gain ground in India to tackle the diabetes and obesity crisis."Remember, the GLP-1 field is just beginning to explode. There'll be many newer drugs with less and less side effects and easier to use," Dr. Mithal sayssaid.- EndsMust Watch
