Kale, often celebrated as a superfood, is one of the most nutrient-rich leafy greens available. Belonging to the cruciferous vegetable family alongside broccoli and Brussels sprouts, kale offers numerous health benefits but also raises questions about its impact on thyroid health when consumed raw.
Nutritional Powerhouse
Kale is a low-calorie, high-nutrient food packed with essential vitamins, minerals, and antioxidants. Just one cup (21 grams) of raw kale contains only 7 calories while delivering significant amounts of vitamins A, C, and K, as well as minerals like calcium, potassium, magnesium, and manganese.
In addition, kale is rich in antioxidants that help neutralize free radicals, potentially lowering the risk of conditions such as heart disease, Alzheimer’s, and certain cancers. Its nutrient profile makes kale a great choice for promoting heart health, supporting eye health, and protecting against chronic diseases.
Raw vs. Cooked Kale: Nutritional Differences
Raw kale has a slightly bitter taste, which can be softened through cooking methods like steaming or sautéing. However, cooking can significantly reduce its nutrient content, including antioxidants, vitamin C, and minerals such as calcium and magnesium.
A study examining different cooking methods found that steaming retained the most nutrients and antioxidants compared to other methods like boiling or frying. For those who prefer cooked kale, lightly steaming it for a short duration may help preserve its nutritional value while enhancing its flavor and texture.
Concerns About Raw Kale and Thyroid Health
One of the key concerns about consuming raw kale is its high content of goitrogens, particularly goitrins. These compounds can interfere with iodine absorption, potentially impacting thyroid function. Iodine is crucial for producing thyroid hormones, which regulate metabolism, energy levels, and other vital bodily functions.
Excessive consumption of raw kale—around 2.2 pounds (1 kg) daily over several months—has been shown to impair thyroid function in healthy adults. However, moderate consumption is generally considered safe for most people.
Studies indicate that eating moderate amounts of cruciferous vegetables, including kale, does not significantly affect thyroid hormone levels, even in individuals with thyroid issues. Additionally, cooking kale deactivates the enzyme responsible for releasing goitrins, further reducing any potential impact on thyroid health.
Balancing Benefits and Risks
For those with thyroid concerns, combining kale with iodine-rich foods such as seafood or dairy can help mitigate any potential risks. Cooking kale is another effective way to lower goitrin content while still enjoying its health benefits.

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.

Have you ever heard from your grandparents that you must wrap your dinner up before the sundown? An old saying, is today's science, as a US doctor, Dr Ashley Lucas, PhD nutritionist and dietitian explains why is it beneficial to eat your dinner early. Lucas says that the ideal time to have dinner can in fact help you lose weight and shed some extra pounds.
The US is grappling with the rising cases of obesity. More than 2 in 5 adults are obese, which makes it nearly 42% of the population, as per the data by the US Centers for Disease Control and Prevention (CDC).
Several studies too have predicted that by 2050, the United States may face an obesity epidemic. Being overweight or obese increases the risk of many chronic diseases, including type 2 diabetes, heart disease, stroke, high blood pressure, high cholesterol, and certain kinds of cancer. This is why maintaining an ideal weight for body is crucial for a healthy living.
While eating a well balanced food is necessary, the time when you have your dinner really matters.
Dr Lucas says that there is a golden rule for having dinner. The way to know is to follow the sun, as it is in this pattern that regulates hormones.
"The ticket to success is really to follow the sun. Our bodies, metabolism, and hormones are most efficient at digesting and metabolizing food during daylight hours. So, aim to wrap up your dinner by 6 to 7pm and strive for a 12-hour gap before your next meal," said Dr Lucas in an Instagram video.
"If you eat close to your bedtime, then your sleep is not going to be as deep," she says. "Well, munching close to bedtime can affect your sleep quality, leading to less restful nights. Plus, there are some genetic factors that link late night eating to a higher risk of type 2 diabetes," she further added.
There are studies too that also suggest the same. However, skipping meal is also not ideal as it hinders your biological clock and sleep.
Eating late could lead to acid reflux, and also weight gain. The theory that suggests the weight gain is called food-induced thermogenesis, which is the time your body takes to burn the food you eat. This is higher in the morning and lower in the evening. This is why, wrapping up your dinner by 7pm is ideal. However, more research is still required in this field.
There are also numerous studies that show that eating late may increase the risk of metabolic syndrome. It is a group of conditions that includes insulin resistance, obesity, high blood pressure, and high cholesterol.
If you also go to bed shortly after having a feal, it may increase the risk of acid reflux. This happens when acid in stomach begins to irritate the esophageal lining. If it happens for a long time, it could cause gastroesophageal reflux disease (GERD).
Eating late could also lead to overeating, or choose easy, especially foods which are unhealthy. A study also showed that among the 104 people with obesity, 45% chose sweets as the snack of choice in the evening and night.
