Green Tea is a beverage made from unfermented leaves of the Camellia Sinensis—a plant native to Asia. It is one of the least processed types of tea. Moreover, unlike black tea, it doesn't undergo oxidation and retains polyphenols and catechins—two types of antioxidants. To create green tea, leaves are steamed, pan-fried and then finally dried. While there is not a lot of scientific research to prove the health benefits of green tea, certain studies have indicated that this beverage boosts weight loss and helps aid liver disorder, Type 2 diabetes, Alzheimer's disease and more.
May Reduce Inflammation
Green tea drinking was shown to lower a specific marker of inflammation, called tumour necrosis factor-alpha, in individuals with metabolic syndrome, according to a 2024 systematic review and meta-analysis published in Preventive Nutrition and Food Science.
Supports Brain Function
Studies show tea consumption, along with a heart-healthy diet, may improve some brain function. L-theanine, an amino acid in green tea, has been found to help improve brain function by strengthening memory and reducing anxiety. Another compound found in green tea, epigallocatechin gallate (EGCG), along with L-theanine has been shown to activate nerve cells and reduce stress.
Might Improve Blood Sugar And Cholesterol Levels
Green tea may also help defend against heart disease by supporting healthy cholesterol. Although not consistently, green tea has been shown to reduce low-density lipoprotein (LDL) or bad cholesterol, reduce total cholesterol levels and reduce triglycerides, according to a 2020 meta-analysis published in Nutrition Journal. Experts believe that catechins, one type of antioxidant found in green tea, may be responsible for this cholesterol-lowering effect.
Aids In Digestion
Green tea has been shown to shape the gut microbiome to promote health. Researchers believe that the compounds in green tea favour the growth of beneficial bacteria in the gut and work to decrease harmful bacteria, according to a 2021 review study published in Molecules. Green tea may also aid in the production of short-chain fatty acids, aka postbiotics, which are considered the health-promoting byproducts of the bacteria in your gut.
May Reduce Cancer Risk
The antioxidants found in green tea, particularly polyphenols, aid in protecting cells from oxidative damage, a factor that contributes to several chronic illnesses and cancers. Polyphenols can help prevent the formation of free radicals that may cause damage to or the death of cells, which may ultimately reduce the risk of cancer, according to a 2020 study published in the Cochran Database of Systematic Reviews.
However, like any other food item, green tea also yields optimum benefits when it is consumed in moderation.
Firstly, it is important to remember that green tea is not caffeine-free. Its excess consumption can lead to symptoms such as anxiety, restlessness, jitters, headache, nausea, increased heart rate or trouble sleeping. While everyone has different sensitivity levels to caffeine, the Food and Drug Administration cites 400 milligrams per day—about 10 cups of green tea—as the maximum amount of caffeine healthy adults should consume each day.
The promising health benefits of green tea may be negated with added sugar or even an excess amount of honey. So be mindful of the sweetness you’re adding, and consider opting for a slice of lemon to add flavour without added sugar.

Magnesium supplements are everywhere. Whether you see it on pharmacy shelves or wellness blogs and social media where influencers who swear by them. You’ve probably heard someone claim that a daily magnesium tablet can help you sleep better, ease muscle cramps, or boost your mood. But do you actually need one, or is this just another wellness trend gone too far?
Magnesium is an essential mineral that plays a crucial role in over 300 biochemical reactions in the body. It helps regulate muscle and nerve function, supports a healthy immune system, builds protein, maintains blood sugar and blood pressure levels, and aids in energy production.
Because the body doesn’t produce magnesium on its own, it must come from external sources such as food or supplements. The recommended daily intake varies: 310–420 mg for adults and 30–410 mg for children, depending on age and sex.
The good news? A balanced diet can easily meet these requirements. Magnesium-rich foods include nuts and seeds, leafy green vegetables, legumes, seafood, whole grains, and meat. Even dark chocolate can help, 100 grams of dark chocolate contains around 146 mg of magnesium.
Most people get enough magnesium from food, but certain groups are more vulnerable to deficiency. These include people with gastrointestinal disorders such as Crohn’s disease or coeliac disease, those with type 2 diabetes, people who consume excessive alcohol, and older adults.
If you’re low on magnesium, you might notice symptoms such as muscle twitches, spasms, fatigue, low appetite, nausea, or an irregular heartbeat. However, the only way to confirm a deficiency is through a blood test prescribed by your doctor, which, in most cases, is covered by Medicare.
Magnesium supplements are often promoted as a solution for muscle cramps, migraines, and insomnia. But do they actually work?
While magnesium deficiency can lead to cramps, most cases of muscle cramps are not due to low magnesium. Research shows limited evidence that supplements prevent cramps, especially in older adults.
The link between magnesium and better sleep is also unclear. Some studies found it helped people fall asleep faster, while others found no significant difference.
When it comes to migraines, evidence is stronger. Studies suggest that taking 122–600 mg of magnesium daily for 4–24 weeks may reduce the frequency and severity of migraines in some people.
In general, magnesium supplements are safe when taken in the recommended amounts. However, too much can lead to nausea, abdominal cramps, and diarrhea, because magnesium draws water into the intestines.
Taking extremely large doses (around 5,000 mg daily) can cause magnesium toxicity, which is dangerous. Always check with your doctor before starting supplements, especially if you take other medications.
Magnesium is available in tablets, powders, and even topical forms like creams and bath salts. While these skin-based products may raise magnesium levels slightly, they’re less effective than oral supplements or food sources.
When buying supplements, check the label carefully. Most tablets contain 150–350 mg of magnesium, but formulations vary widely. Some also include additional nutrients like vitamins B6, C, or D, and minerals like calcium or manganese.
Be cautious with vitamin B6, high intake can cause nerve damage over time. If you already take a multivitamin containing B6, avoid magnesium supplements that also include it.

Milk is one of the most common items found in every household and is considered a wholesome food packed with calcium, protein, and vitamin D.
It plays an important role in maintaining strong bones, building muscles, and supporting overall health. Because of its nutritional richness, milk is often called a complete food. However, it is essential to ensure that the milk you consume is pure and free from adulteration. Contaminated or diluted milk can lose its nutritional value and even harm your health. Fortunately, there are simple methods you can try at home to find out whether your milk is pure or adulterated.
Food adulteration is the intentional act of reducing the quality of food by mixing or replacing it with inferior substances, or by removing essential components. The same applies to milk. While contamination of food can happen accidentally during storage, transport, or distribution, adulteration is done deliberately for profit.
Milk adulteration involves adding materials such as water, urea, detergent, or other chemicals to increase volume or extend shelf life. This practice reduces the nutritional value and can pose serious health risks to consumers.
There are a few simple ways to check for adulteration using common items at home:
Regularly drinking adulterated milk can cause several health issues from short-term stomach discomfort to severe, long-term illnesses. The exact effects depend on what substance has been added, ranging from diluted water to harmful chemicals.

A common vegetable has been found to help reduce blood pressure in older adults, according to a new study. Beetroot juice can lower blood pressure in people aged 60 and above by targeting certain potentially harmful bacteria in the mouth. Researchers at the University of Exeter studied how younger and older adults responded to beetroot juice, which is rich in dietary nitrates. These nitrates are converted by the body into nitric oxide, a compound that relaxes and widens blood vessels, helping to lower blood pressure.
The study included 39 adults under the age of 30 and 36 adults in their 60s and 70s. For two weeks, each group received shots of beetroot juice. After a two-week break, during which participants used antiseptic mouthwash daily, they were given a placebo juice without nitrates for another two weeks.
Researchers analyzed the bacteria in participants’ mouths using gene sequencing. In both groups, the oral microbiome—the community of microorganisms in the mouth—changed after drinking nitrate-rich juice, though the effects were different depending on age. In older adults, there was a reduction in common bacteria that can sometimes cause infections and an increase in bacteria that support health. The older participants also showed lower blood pressure after two weeks of drinking the nitrate-rich juice.
Professor Andy Jones of the University of Exeter said, “This study shows that nitrate-rich foods can change the oral microbiome in ways that may reduce inflammation and lower blood pressure in older adults. This opens the door for larger studies to examine how lifestyle factors and biological sex affect responses to dietary nitrate supplements.”
It may be possible to drink beet juice while taking blood pressure medications. However, it’s important to consult a doctor before making any changes to a treatment plan for high blood pressure.
A doctor can advise whether combining beet juice with blood pressure medication could lower blood pressure too much. If this happens, a person may experience symptoms such as:
Low blood pressure (hypotension) can be serious. If someone experiences severe symptoms that do not improve when sitting or lying down, they should seek immediate medical attention.
Eating beets may help reduce blood pressure, but most research has focused on beet juice rather than whole beets.
Currently, there isn’t enough scientific evidence to confirm that eating beets has the same effect as drinking beet juice.
If someone wants to explore dietary changes to manage their blood pressure, it’s best to consult a doctor before making adjustments.
