Avocados Are A Superfood—But Do You Know How to Store Them Properly?

SummaryAvocado browning occurs when the fruit's natural enzymes are exposed to oxygen in the air. Storing them perfectly can help them prevent them from getting oxidized.

Knowing how to store avocados can make all the difference in whether or not you can enjoy them. They are a notoriously fickle fruit—one second, they seem like they're days away from being ripe enough to enjoy, and the next second you're left with an overripe mess. While ultra-nutritious, the unpredictability of this fruit can result in food waste.

Why Do Avocados Turn Brown?

Avocado browning occurs when the fruit's natural enzymes are exposed to oxygen in the air, triggering a chemical reaction called enzyme polyphenol oxidase. Although the discolouration might look unappetizing, it doesn't make the avocado unsafe to eat. Contrary to popular belief, leaving the pit in an avocado won’t prevent browning. The flesh directly under the pit remains green simply because it isn’t exposed to air, not because the pit has any anti-oxidizing properties.

Storing Whole Avocados

Unripe Avocados

For unripe avocados, store them on your countertop away from other fruits and vegetables. This helps avoid exposure to ethylene gas from produce like bananas, which speeds up ripening. Check daily, as unripe avocados generally take four to five days to mature. An avocado is ripe when it yields slightly to light pressure and has dark green to black, bumpy skin.

Ripe Avocados

To prolong the life of ripe avocados, place them in the refrigerator. Store them in an airtight container or in the crisper drawer, but be cautious if they’re near ethylene-producing fruits like apples. Depending on ripeness, they can stay fresh for several days.

Storing Cut Avocados

Halved Avocados

To store a halved avocado, leave the pit and skin intact. Rub olive oil or lime juice on the exposed flesh, wrap it tightly in plastic wrap, and refrigerate. This method slows oxidation, keeping the fruit fresh for about two days.

Sliced Avocados

For sliced avocado, use a food storage container covered with plastic wrap pressed directly against the flesh to prevent air pockets. Lime or lemon juice can add a layer of protection but may alter the flavour. Due to the exposed surface area, sliced avocado is more prone to browning, making it harder to store for extended periods.

Storing Guacamole (mashed avocadoes)

To store guacamole, place it in a bowl, cover it tightly with plastic wrap so that it touches the surface of the guacamole, and refrigerate. Adding lime juice is optional but may help slow oxidation. Although the top layer may be brown, it can easily be scraped off before serving.

Why Should You Eat Avocadoes?

Avocadoes are a known superfood packed with antioxidants and nutrients that improve blood pressure management, eye health and energy production. While their creamy texture and nutty flavour make them a world favourite, they are packed with folate, magnesium, Vitamin B, Potassium and Copper. This makes them a perfect fruit for digestion and metabolism boost. Incorporating avocado into your morning meal can give you a sustained energy boost. Adding avocados to your diet can improve heart health.

Avocadoes are a great source of lutein and zeaxanthin, two carotenoids that protect against oxidative damage to eye cells. Avocados may improve mental well-being by combating depression. If you're pregnant, avocado could help protect your baby's health too.

Does Ghee Coffee Really Work? Experts Answer

SummaryGhee Coffee is a trending health drink that combines coffee with ghee and sometimes coconut oil or MCT oil

Ghee coffee, also known as bulletproof coffee, has gained popularity as a trendy health drink, particularly for people trying to lose weight. This unique health drink combines coffee with ghee and sometimes coconut oil or MCT oil. The trend caught traction earlier this year, with celebrities like Rakul Preet Singh, Bhumi Pednekar, and Jacqueline Fernandez promoting it on their social media pages.

Does Ghee Coffee Really Work?

Ghee coffee offers numerous benefits, including sustained energy, improved mental focus, and enhanced weight loss. Ghee is rich in healthy fats and when added to coffee, it provides a slow-burning source of energy, helping to maintain stable blood sugar levels and prevent energy crashes.

- Sustained Energy: Ghee coffee provides a slow-burning source of energy, helping to keep you energized throughout the day.

- Improved Mental Focus: The combination of coffee and ghee may enhance mental clarity and focus.

- Enhanced Weight Loss: Ghee is rich in healthy fats that can support weight loss efforts by promoting satiety and fat metabolism.

- Rich in Healthy Fats: Ghee contains butyrate, a fatty acid that supports gut health and reduces inflammation.

- Stable Blood Sugar Levels: The fats in ghee help maintain stable blood sugar levels, preventing energy crashes.

However, experts caution that while ghee coffee can be part of a balanced diet, it may not be suitable for everyone. The high-fat content makes it calorie-dense, which could lead to weight gain if consumed in excess. Additionally, those with dairy sensitivities should avoid ghee. As with any health trend, it's essential to consider individual dietary needs and consult with a healthcare professional before making it a regular part of your routine.

Here’s What Experts Say

In their verdict on this popular health drink, experts have asserted that it should be consumed in moderation. Dr. Thiagarajan Srinivasan, Liver Transplant Specialist at MGM Healthcare, asserted that the consumption of ghee is good for health but only when it is of limited quantity. He advised people not to follow celebrity trends and discredited them as "pseudo-science."

Is Yerba Mate Nature's Answer To Ozempic? Risks And Benefits

Is Yerba Mate Nature's Answer To Ozempic? Risks And Benefits

SummaryOzempic is a prescription GLP-1 drug for weight loss, while yerba mate is a natural tea that boosts metabolism and curbs appetite. Science-backed, but can it truly rival Ozempic?

Dubbed as "Nature's Ozempic" by TikTok enthusiasts, yerba mate, a traditional South American tea, has captured interest for potentially stimulating metabolism, suppressing appetite, and aiding in weight loss. With more and more scientific evidence tying it to metabolic effects, one can't help but question whether it has the potential to outdo Ozempic, the well-loved GLP-1 receptor agonist drug used for managing weight and type 2 diabetes. But first, before it's time to switch, there is a great need to dig into the positives and negatives about this herbal beverage.

Yerba mate is a herbal tea prepared from the leaves of Ilex paraguariensis, a South American native plant found in countries such as Argentina, Brazil, Paraguay, and Uruguay. Brewed traditionally in a mate gourd and drunk through a metal straw, yerba mate has an earthy, slightly bitter flavor. It has been used for centuries for its stimulating properties and health benefits, especially its contribution to weight loss and metabolic function.

Yerba Mate vs Ozempic

Part of the reason yerba mate has drawn comparisons to Ozempic is because of its impact on appetite and metabolism. Studies indicate that yerba mate can spur weight loss by raising levels of GLP-1, a hormone that controls blood sugar and appetite. One study discovered that active ingredients in yerba mate, especially dihydroferulic acid, act on gut bacteria to activate GLP-1 production, emulating some of the effects of Ozempic.

Furthermore, a 2015 study showed that yerba mate enhances lipid metabolism, which reduces cholesterol levels and controls gene expression associated with obesity. Another study in 2021 validated that yerba mate inhibits fat accumulation, suppresses appetite, and boosts metabolism, rendering it a viable weight management tool.

Can Yerba Mate Replace Ozempic?

Although yerba mate and Ozempic have some similarities, they are not the same. Ozempic is a prescription medication that has been thoroughly tested in clinical trials and has FDA approval for type 2 diabetes and weight loss. Yerba mate is a natural supplement that does not have regulatory approval as a medical treatment.

Unlike Ozempic, in which the drug is prescribed at certain strengths, yerba mate is of varying concentrations and strengths. Although it can aid in weight loss and metabolic health, it must be viewed as an adjunct therapy and not in place of prescription medication.

Health Benefits of Yerba Mate

Aside from weight control, yerba mate has several health benefits:

1. Increases Energy and Concentration

Yerba mate has caffeine, theobromine, and theophylline that give a smooth, jitter-free energy without crash. These constituents increase mental alertness and maintain energy levels without the crash as in coffee.

2. Supports Heart Health

Research indicates that yerba mate lowers LDL cholesterol and blood pressure, which prevents heart disease. Its high antioxidant content also enhances cardiovascular function through combating oxidative stress.

3. Aids Digestion

Yerba mate supports a healthy gut microflora, enhances digestion, and alleviates bloating. Its bioactive ingredients enhance the absorption of nutrients and general health of the gut.

4. Improves Physical Performance

Some athletes take yerba mate to enhance endurance and decrease muscle exhaustion. It enhances oxygen consumption and delays lactic acid accumulation, enhancing recovery.

5. Rich in Antioxidants and Nutrients

Yerba mate is filled with polyphenols, chlorogenic acid, and vitamins including B-complex, magnesium, potassium, and zinc. They aid in immune function, fight inflammation, and enhance overall health.

Possible Side Effects of Yerba Mate

Although yerba mate has numerous advantages, consuming too much may have dangers:

1. Increased Cancer Risk

Research shows that consumption of more than a liter of yerba mate per day, especially at high temperatures, can be associated with an increased risk of esophageal and other cancers. The risk is increased among smokers and alcohol drinkers.

2. Caffeine-Related Side Effects

Yerba mate has caffeine, which can lead to restlessness, insomnia, stomach upset, and increased heart rate, particularly in sensitive individuals to stimulants.

3. Possible Drug Interactions

As yerba mate lowers blood sugar, taking it along with drugs like Ozempic can heighten the risk of hypoglycemia (low blood sugar), resulting in symptoms such as fatigue, dizziness, and sweating.

4. Risks of Nutrient Deficiency

Since yerba mate is appetite-suppressing, high use might result in poor nutrient consumption. Those using it to lose weight need to make sure that they are keeping their diet well-balanced.

Should You Include Yerba Mate in Your Daily Routine?

Yerba mate is becoming increasingly popular worldwide as a natural method of increasing metabolism, aiding weight loss, and improving energy. While it has been dubbed "nature's Ozempic," it must not be regarded as an immediate substitute for prescribed weight-loss drugs.

Yerba mate is a strong herbal drink with possible metabolic advantages, but the comparison to Ozempic must be approached cautiously. Although it can aid in weight loss, enhance heart health, and supply prolonged energy, it is no more a supplement to treat obesity or diabetes. With ongoing research, yerba mate remains a compelling option to consider for those who want a natural solution for whole body wellness. Although attracted to its antioxidant profile or supplement to suppress appetite, this South American superfood is well worth investigating—especially with responsible consumption.

What Do The Studies Say?

The US Department of Agriculture states that vinegars contain a substance called mother which has strands of proteins, enzymes, and friendly bacteria. These are mostly found in organic, unfiltered apple cider vinegar. They have a murky appearance.

As per the National Library of Medicine's research paper, titled Antimicrobial activity of apple cider vinegar against Escherichia coli, Staphylococcus aureus and Candida albicans; downregulating cytokine and microbial protein expression, vinegar can also help kill pathogens, including strains of bacteria.

People have also traditionally used vinegar for cleaning and disinfecting, treating nail fungus, lice, warts, and ear infections.

In fact, Hippocrates, the father of modern medicine, used vinegar to clean wounds more than 2,000 years ago.

A 2021 study Antibacterial apple cider vinegar eradicates methicillin resistant Staphylococcus aureus and resistant Escherichia coli, also reveals that vinegar can be used as a great food preservative, as it inhibits bacteria like E.coli from spoiling food. This is why in Japanese cuisine, vinegar is also used as cooking ingredient.

As per a 2019 clinical trial, titled The effect of apple vinegar consumption on glycemic indices, blood pressure, oxidative stress, and homocysteine in patients with type 2 diabetes and dyslipidemia: A randomized controlled clinical trial, vinegar consumption could have beneficial effects on the glycemic index and oxidative stress in individuals with diabetes and dyslipidemia. This could help lower blood sugar levels and manage diabetes.
