Guava, a tropical fruit native to Central America, is fast gaining popularity as a powerhouse of nutrition. Both the fruit and its leaves are rich in essential nutrients, including vitamin C and potassium, which may support various body functions like heart health, digestion, and immunity.
Guavas are typically oval-shaped with light green or yellow skin and contain small, edible seeds. While the fruit is often enjoyed raw or in juices, guava leaves are also brewed into herbal teas or consumed in the form of dietary supplements for their health-promoting properties. Rich in antioxidants, vitamin C, potassium, and dietary fiber, guavas offer several health benefits that are increasingly being backed by scientific research.
Emerging evidence suggests guava leaf extract can help manage blood sugar. Cell culture and animal studies from 2020 and 2022 indicate that guava leaf extract may lower blood sugar levels, improve insulin resistance, and enhance long-term blood sugar control. This could prove beneficial for people living with diabetes or those at risk. These findings have also been observed in some human studies, showing promise for its therapeutic potential.
Guava's positive impact on heart health is supported by its high antioxidant and vitamin content. Researchers believe that these nutrients help protect the heart from free radical damage. Additionally, the fruit’s high potassium and soluble fiber content further support cardiovascular well-being. Guava leaf extract has been linked to reductions in blood pressure and LDL (bad) cholesterol, and an increase in HDL (good) cholesterol. Since elevated blood pressure and bad cholesterol are key risk factors for heart disease and stroke, guava consumption may offer protective benefits. A 2022 study also found that eating ripe guava helped lower overall blood pressure, reinforcing earlier findings.
Guava leaf extract may provide relief from dysmenorrhea, or painful menstrual cramps. Some studies suggest it reduces pain intensity and may also decrease uterine bleeding and other related symptoms. This makes it a promising natural remedy for menstrual discomfort.
Guavas are an excellent source of fiber, promoting healthy digestion and regular bowel movements. Just one guava delivers about 12% of the daily recommended fiber intake. Guava leaf extract also shows antimicrobial properties that may help reduce diarrhea by eliminating harmful gut bacteria.
Low in calories and high in fiber, guavas are a filling and nutritious snack, making them ideal for weight management. Unlike many low-calorie options, guavas also provide important vitamins and minerals.
Guava leaf extract has demonstrated anti-cancer activity in lab and animal studies by preventing the growth of cancer cells. This is attributed to its potent antioxidants, which neutralize cell-damaging free radicals. However, more human studies are required before making conclusive claims.
Guavas are one of the richest sources of vitamin C — even more than oranges. One guava offers over twice the daily requirement, supporting immune function and helping the body fight off infections. Vitamin C is known for its antimicrobial effects and ability to reduce the severity of colds.
The antioxidants and vitamins in guavas may benefit skin by protecting it from premature aging. Guava leaf extract, when applied topically, has shown potential in treating acne, though more studies are needed.

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.
