Vegetarians and vegans have enjoyed soy-based foods like tofu also known as bean curd for a long time which is known to be an excellent substitute for animal-based protein that can be high in saturated fat and cholesterol.

In some countries such as China, Japan, Indonesia, Malaysia, Singapore Vietnam, Thailand, and Korea, tofu and soy foods are a protein staple.

Ten Health Benefits of Tofu

1) Complete Protein Alternative for Meat (macronutrient)

Protein is a macronutrient like carbs and fat, which means the body needs a relatively greater quantity of it to sustain.

It is vital for cells, muscles, bones, enzymes, hormones, and blood.

Since the body has no protein store to draw when needed you should continue to include protein-rich food into your diet and tofu is a complete protein with all the nine essential amino acids the body needs.

2) Tofu for Strong Bones and Reduce the Risk of Osteoporosis

Since your bones consist of calcium and your body doesn’t produce calcium, it is important that you get it from diet.

Hence tofu is a great alternative for calcium especially for vegans and possibly a better option than dairy due to its animal protein which can have a calcium-leaching effect.

Postmenopausal women tend to be at risk of osteoporosis which makes bones weaker since their bodies make less estrogen that provides protection against bone loss

But according to a research team led by the University of Hull in the U.K. isoflavones in tofu are similar in structure and function to estrogen and considered to be an effective option in reducing the risk of osteoporosis for women

Further, a medical study in Sweden has shown, women who consumed more milk still had a higher risk of bone fractures whereas people of Okinawa Japan consume a considerable amount of tofu and the incidence of fractures and osteoporosis is low.

3) For Brain Health

Tofu is a good source of alpha-linolenic acid (ALA), which is a type of omega-3 fatty acid. The body can also convert ALA into other two forms of omega-3 i.e. EPA & DHA.

Omega-3 is known to help control blood clotting, build cell membranes in the brain and ALA may also help in preventing and treating depression according to the University of Maryland Medical Center.

One research has found that isoflavones found in tofu and other soy-based products can be linked to a positive influence of nonverbal memory, verbal fluency, and other brain functions.

4) Reduce the Risk of Cardiovascular Disease

Isoflavones in tofu have also been found to aid in reducing the levels of LDL (bad cholesterol), and decrease other risk factors for cardiovascular disease, such as weight, body mass index (BMI), and total cholesterol to improve heart health.

Further isoflavones could lower the levels of oxidized cholesterol and reduce the chances of forming threatening plaques that increase the risk of heart disease.

5) Reduce Blood Pressure

According to research, tofu protein which is fairly high in dietary phosphorus, known to have an inverse association with blood pressure.

Another study has found that people who ate soy products such as tofu had lowered their blood pressure since isoflavones are known to boost enzymes that could widen the arteries that result in lower blood pressure.

6) Boosts the Immune System

Tofu being a rich source of proteins, nutrients, minerals, and other antioxidants, it’s a food source that can boost the immune system.

Your immune system is made up of proteins, therefore antibodies and other immune system cells depend on it, whereas a diet poor in protein can lead to weaker immunity.

Tofu is also a good source of zinc that strengthens the immune system, helps in healing wounds, and a remedy for the common cold.

7) Protection Against Oxidative Stress

When more free radicals exist in your system oxidative stress can occur which causes damage to fatty tissue and DNA that can lead to a vast number of diseases over time such as cardiovascular disease, neurological diseases, cancer, respiratory disease, and kidney disease.

Thankfully tofu comes with precious antioxidants, that can trap or destroy free radicals in order to guard us against oxidative stress.

8) Tofu Comes with Cancer Protecting Properties

Tofu comes with soyasaponins which are regarded to have cancer preventing, immune-regulating and antioxidative properties.

Studies have also shown the ability of genistein, daidzein and other soy compounds found in tofu to contain cancer cell growth, reduce the risk of tumor formation and prevent cancer development by lessening inflammation and blocking proteins that nurture cell growth.

Selenium in tofu may also help in reducing the risk of certain types of cancers due to its ability to minimize DNA damage & oxidative stress, improve the immune system and suppress cancer cells.

This was further evidenced with studies published in the 80s and early 90s that showed how individuals with a deficiency of selenium had an increased risk of cancer.

9) Reduce the Risk and Help Treat Diabetes

Studies suggest soyasaponins in tofu may influence blood glucose levels by regulating plasma glucose levels and prevent diabetic complications with its antioxidant activity.

Traditional antidiabetic drugs tend to have side effects such as weight gain which has the potential to complicate it further though soyasaponins in tofu can reduce body fat which can be a good option for patients with diabetes.

Further isoflavones in tofu can be beneficial for diabetes, due to increased insulin secretion, better blood sugar control, and defense from antioxidants.

10) Can Provide Relief for Mild Menopausal Symptoms

Menopause is a cycle where the female body gradually stops releasing estrogen on a monthly basis and this drop causes a range of menopausal symptoms such as hot flashes, night sweats, and fatigue.

According to The North American Menopause Society, soy isoflavones also found in tofu can be a natural remedy for mild menopausal symptoms rather than opting for estrogen replacement therapy.

Many women have reported a reduction in their hot flashes and night sweats when they regularly consume soy foods such as tofu.

Keep in mind though, tofu being a natural remedy it may take some time (several weeks or even months) before you start seeing an alleviation of menopausal symptoms.

Conclusion

As you learned, tofu is an excellent substitute for meat and has many health benefits that cannot be overlooked especially for vegans!

We encourage you to go for non-GMO tofu and make sure you eat it in moderation few times a week for optimum health.

Note:

If you’re trying tofu for the first time but you have a specific medical condition (including any allergies), taking medications, anticipate surgery, pregnant, lactating, or a parent considering tofu for your child, it’s sensible to consult healthcare professionals before adding it to your diet.

13 Health Benefits of Green Tea, Nutrition Facts & Side Effects

September 10, 2018 By Dishan Mendis Leave a Comment

Tea being one of the most consumed beverages in the world beating coffee and being second to only water, it only makes sense to know the health benefits of a cup of green tea.

It is native to East Asia and has initially been used as a medicine and consumed for centuries in countries such as China, Japan, and Korea.

Green tea stands out from other types of tea in terms of health as it’s not fermented and being minimally processed enables it to retain its health properties.

Therefore it is abundant with antioxidants such as flavanols which represent 30% of the dry weight of green tea leaves making it a “superfood.”

Let’s see the 13 health benefits of drinking green tea, nutrition facts, any side effects, and how much you should drink for optimum health.

Health Benefits of Green Tea

1) Sipping Tea Helps You Reduce Stress, Relax and Improve Sleep

Well, we all know the relaxation & calmness we get during a small session over a hot cup of tea.

From ancient times, green tea was known for its soothing properties.

L-theanine the amino acid derived from the leaves of green tea helps to relax the brain and has been studied for its psychological and stress-reducing benefits.

This particular amino acid has been shown to trigger the release of alpha-waves, which provide relaxation, focus, and creativity [2].

The other advantage of L-theanine is its ability to improve the quality of sleep, by no means as a sedative but with its effects on reducing anxiety and aiding in relaxation [3]. Do note that a state of relaxation may considerably help people fall asleep more quickly as well.

2) Could Lower Your Risk of Type 2 Diabetes and Insulin Resistance

Why green tea may help people with diabetes is because it supports the metabolic function better and helps sensitize cells enabling better metabolism of sugar.

According to one Japanese study, those who drank more green tea a day were 33% less prone to have type 2 diabetes than those who consumed the least amount of green tea a week.

Polyphenols in green tea may help in regulating glucose, and reduce the risk of diabetes or control.

One meta-analysis of 17 controlled trials, showed that green tea had positive effects of substantially reducing fasting glucose and HbA1c (avg. blood glucose levels in the past 2-3 months)

3) Improves Brain Function, Help Prevent Memory Loss and Protect Brain Cells From Free Radical Damage

Our brains can particularly be susceptible to damage by chemicals called free radicals and also due to each cell’s high metabolism and fatty acid structures. High antioxidants in green tea can help protect against this damage.

According to one review on several studies, green tea influences in lowering anxiety while aiding in memory, attention and brain function (e.g. activation of working memory) [4].

Also, EGCG in green tea has been found to have an effect on neuroprotection by reducing free radical damage, specifically safeguarding new neurons in the hippocampus which controls learning and memory.

Further, L-theanine in green tea helps to lower the levels of stress hormone corticosterone which inhibits certain brain activity. As a result, it can avoid the negative interference with memory and learning.

4) May Reduce Your Risk of Cardiovascular Disease, and Strokes

Green tea has been assumed to have an influence in modest reductions of total and LDL (bad) cholesterol which can help to reduce the risk of heart disease & stroke.

In a study of 40,530 Japanese adults showed that those who consumed more green tea a day had a 26% lower risk of mortality from heart attack or stroke.

A meta-analysis of observational studies where five in green tea and thirteen in black tea found that higher amount of green tea drinkers had a 28% lower risk in the most common type of cardiovascular disease which is the coronary artery disease than those who consumed the least amount of green tea [5].

5) Aids in Lowering Blood Pressure

A meta-analysis of 38 eligible studies with over 1,500 participants showed that green tea consumption is associated with a significant reduction in systolic blood pressure [6].

L-theanine in green tea also has shown positive effects on lowering heart rate and blood pressure.

6) Improved Immune Function

Higher levels of antioxidants in green tea can extremely be of value strengthening the immune system in general.

Routine green tea consumption could protect against the damage from free radicals and similar harmful compounds in the body enabling your immune system to run smoothly.

Antioxidants such as polyphenols are the properties in green tea that’s believed to give its immune-boosting effects. It is also assumed that a polyphenol called catechins may kill influenza viruses.

Overall a healthy immune system can protect you from infections due to bacteria and viruses.

7) Lose Weight, Lower the Risk of Obesity and Improve Physical Performance

Green tea that comes with caffeine is a known stimulant that has demonstrated its ability to aid in fat burning and improve physical performance in a number of studies.

But more importantly, green tea really shines with its wider range of antioxidants particularly the antioxidant EGCG (epigallocatechin gallate) which can have a positive effect on weight loss and weight maintenance.

When EGCG is combined with caffeine the synergistic effect is assumed to further enhance energy expenditure, thermogenesis, and fat oxidation [7]

8) Help Protect Your Skin

Drinking and topical use of green tea seem to fight skin cancer with DNA damage from ultraviolet light rays with its powerful antioxidant, EGCG.

This would also suggest that EGCG can be an anti-aging ingredient that could prolong the signs of aging when consumed or with topical application.

Further, the high content of polyphenols in green tea called catechins are considered to reduce skin irritation, redness, and swelling.

Polyphenols are also a strong antibacterial agent that fight against infection and useful in treating acne with bacterial growth and unclogging pores.

Vitamin B2 and Vitamin E in green tea are also highly beneficial in maintaining skin health!

9) Protect Vision and Reduce The Risk of Eye Disease

Antioxidants such as flavonoids in the tea leaves could help guard your eyes from cataract, age-related macular degeneration (blurriness or no vision) and some types of glaucoma (gradual loss of sight).

Specifically, the flavonoid called gallocatechin seems to operate like a sunscreen for your eyes defending the retina against harmful UV rays.

According to other researchers, antioxidants such as catechins and vitamin E are expected to protect the delicate tissues of the eye from various eye diseases as well.

10) May Lower Your Risk of Some Types of Cancer

The rates of many cancers seem to be much lower in Asia where green tea is native to many of those countries than other parts of the world [8].

There have been more than 50 epidemiologic studies on the relationship between tea consumption and the risk of cancer that have been published since 2006.

Though the results of these studies can be inconsistent, some show a link between tea consumption and lower risks of cancers such as colon, breast, ovary, prostate, and lung.

Some studies have shown that green tea extracts have some capability of discontinuing the cancer cells from growing. This could possibly be due to its polyphenols and the subgroup called catechin which are the antioxidant properties.

An American study done in 2012 gave polyphenon E which is a green tea extract to 42 patients with chronic lymphocytic leukemia where they were not taking any other type of treatment.

Though it is a small trial, the results were promising and found that the number of leukemic cells in a third of the participants were lessened and their lymph nodes have shrunk.

Also, the polyphenols in green tea such as EGCG, EGC, ECG, and EC are antioxidants that have significant free radical scavenging activity and may guard cells against harmful effects of DNA damage due to oxidative stress.

11) Lowering Your Risk of Alzheimer’s and Parkinson’s

According to one study, green tea consumption which is rich in antioxidants has been linked with a 54% reduction in cognitive decline possibly due to its protection against free radicals and oxidation as we learned before.

One study looked at the effect of green tea on Alzheimer’s found that amyloid plaques that play a role in neurodegenerative disorders and are formed with the binding of certain minerals such as iron, copper or zinc can be prevented with the presence of EGCG.

In another meta-analysis of over 1,418 studies discovered that green tea consumption was associated with a reduced risk of Parkinson’s disease.

However, the consumption of green tea could be beneficial before the onset of these diseases.

12) Could Reduce Inflammation in Arthritis Cases and Promote Bone Health

The higher levels of polyphenols (antioxidants) in green tea are believed to have strong anti-inflammatory properties which reduce inflammation and slow cartilage deterioration.

Studies also have shown that EGCG the polyphenol with potent antioxidant effects in green tea can inhibit the production of molecules that trigger joint damage in people with rheumatoid arthritis (RA) [9].

New research from Hong Kong discovered that green tea, may promote bone health and have the capacity to lower the risk of osteoporosis and other bone diseases.

A catechin in green tea called EGC seems to stimulate the process of an important enzyme that promotes bone growth and EGC also may increase the level of bone mineralization, which strengthens bones.

13) Green Tea May Help You Live Longer

A Japanese study shows those who drank green tea each day tend to have a lower risk of death.

Women who drank 5 or more cups of green tea daily reduced their risk of heart disease by 31% and men who drank the same amount of green tea reduced their heart disease risk by 22%.

On the whole, considering that green tea drinkers having a lower risk of heart disease, strokes and with all the above health benefits we discussed, it is sensible to assume that this beverage could help you live longer.

Any Side Effects of Drinking Green Tea?

Considering the length of time green tea has been in consumption, there are no known side effects of drinking green tea for adults, in general.

However, it’s worth noting a few risks with over-consumption or unique personal conditions:

Just like other types of tea, green tea has a substance called tannins. It can interfere with iron absorption, thus it is recommended drinking green tea at least after an hour of having an iron-rich meal.
Green tea is quite low in caffeine compared to coffee, but if you have severe caffeine sensitivities this is something that you should take into account.
If you’re taking any drugs as blood thinners we would not recommend drinking green tea at the same time due to vitamin K. Though raw tea leaves have high concentrations of vitamin K your brewed cup of tea would have less than 1 mcg of vitamin K per serving which can have a negligible effect if you’re not over consuming.
If you’re taking any green tea supplements they may contain high levels of active substances that may interact with other supplements or medications
Always consult a doctor before having green tea if you’re a patient with renal failure, liver disease, heart conditions or any other major medical issues.

How Much Green Tea Should You Drink?

Many researchers on green tea often suggest having it in moderate amounts of 3 to 5 cups a day.

Drinking more than 5 cups a day may have more risks than benefits and keeping it in moderation with a few cups a day would help you to reap its optimal health benefits.

As you learned, there is a broad range of health benefits you get besides relaxing with a hot cup of green tea. It’s certainly a lot healthier than the most famous black tea in the West.

Make sure you avoid sugar, or other sweeteners and have it in moderation over a long period of time to enjoy all the health benefits!

Now pour that green tea and have a cup of life to feel great!
