The truth you need to know about eggs
The egg has something of a chequered past. In the 1950s and 1960s, they were heralded as the best way to start your day with the famous "go to work on an egg" advertising slogans. But by the 70s, received wisdom had almost flipped on its head: eggs were the bad boys of nutrition, carrying a dangerously high level of cholesterol, which had been linked to an increased risk of heart disease. Limit your intake to three a week, was the thinking - and never have two at once.
So you'd be forgiven for thinking twice before cracking open your egg in the morning. However, despite those decades of negative PR, the macro-history of eggs is very positive. They've long been seen as a reliable, nutritious, cheap and tasty form of nourishment. In many cultures and religions, eggs are a symbol of life and rebirth - and who can deny their replenishing properties on a particularly heavy hangover?
This century, as our understanding of nutrition improves, eggs are firmly back on the menu. No longer a culinary outcast, eggs, particularly poached, scrambled or baked, are a brunch staple, and have become one of the most instagrammed foods around.
Indeed, a new study has revealed that eating an egg a day may reduce the risk of strokes and heart disease.
Researchers from Peking University Health Science Centre in China observed the egg-eating habits of 416,213 participants. Those who reported daily consumption of eggs at the beginning of the nine-year study were found to be at lower risk of the diseases than those who never or rarely ate eggs.
* So eggs actually lower your risk of heart disease? It's time we unscramble this confusing story.
For years, eggs were to be avoided because they were high in cholesterol. A large egg contains roughly 185mg of cholesterol, and the American Heart Association used to recommend a maximum of 300mg of cholesterol per day - so two eggs would see you over the limit. As cholesterol was linked to heart disease, it was logical that eating too much would be dangerous. Warnings were issued, and egg-phobia was disseminated.
Cholesterol is a substance found naturally in the body and produce by the liver. It plays a crucial role in how our cells work, and is required to make Vitamin D, hormones and bile. Too much cholesterol in your blood can accumulate on artery walls, which increases risk of heart attacks and strokes.
But here's the thing: the cholesterol in food has "very little effect on the cholesterol in your blood. It's much more to do with the saturated fat in food" says nutritionist Fiona Hunter. A boiled egg has about 3.3g of saturated fat per 100g; for butter, the figure is 51g per 100g.
Saturated fat, found in meat and dairy products as well as foods containing coconut or palm oil, will up the levels of cholesterol in the blood. Unsaturated fats (oily fish, nuts, seeds, avocados, vegetable oils) can actually lower cholesterol levels.
To understand how this works, you have to know that there are two types of cholesterol: high-density lipoprotein (HDL) and low-density lipoprotein (LDL), otherwise known as "bad" and "good" cholesterol. HDL is considered good as it transports excess cholesterol to the liver, where it can then be expelled by the body, rather than stick to your arteries. LDL ushers the cholesterol to your arteries which can build up causing potential blood clots (and by extension lead to heart attacks or strokes).
How do eggs effect LDL and HDL cholesterol levels? A study from the University of Connecticut found that those eating three eggs a day for a month registered no change in ratio between the two types of cholesterol, implying no difference in risk to heart health. A later investigation at the same institution, in 2012, discovered that LDL cholesterol did not rise in middle-aged people who had eaten three eggs per day, though levels of good cholesterol were boosted.
The recent findings are the latest in a line of research suggesting the health risks of eggs have been overplayed in the past. In 2013, an investigation published in the British Medical Journal claimed that an egg a day, if not keeping the doctor away, would not negatively impact heart health.
So does it keep the doctor away? "Nutritionists and dietitians have always known that eggs are a very nutritious food, for lots of reasons," explains Hunter. "They're a very good source of several vitamins and minerals, some of which, like iodine and Vitamin D, are difficult to find in other foods. They're a real powerhouse of nutrients and protein."
A medium egg contains, among other nutrients:
• 63pc of recommended intake of Vitamin D, useful in a country where most people are deficient.
• 36pc daily requirements of Vitamin B2, vital for growth and bodily repair.
• 108pc required daily Vitamin B12, essential for the body's nervous system and blood cells, as well as producing DNA.
• 39pc daily requirements of biotin, for metabolism, nerve, and digestive and cardiovascular functions.
• 71pc of necessary daily Choline, important for liver function and brain development.
"They've also got iodine and selenium," says Hunter. "One medium-sized egg would provide 42pc of your recommended daily amount of selenium and 34pc recommended iodine." Iodine is especially important for pregnant women, as it's linked with your baby's IQ. "As people turn away from milk our iodine levels are dropping, so eggs are a good way to get it into the diet."
“They're also incredibly convenient, quick and versatile. I'm a big fan of eggs, and would probably eat them for lunch two or three times a week. The smashed avocado on toast with a poached egg on top has introduced a whole new generation to the joy of eating eggs. And they're an excellent source of protein for vegetarians too."
› Should we be limiting our egg intake, then? "I haven't seen any recent research suggesting we should," Hunter continues. "Having said that, we need to eat a variety of foods. I don't think there's any harm in having eggs every day, but the only caveat is your diet would not be hugely varied."
And, of course, the way we eat them can have a big impact on how healthy or unhealthy they are. A fried egg with lots of salt is evidently not as wholesome as a boiled egg. "A boiled egg is a very good snack that isn't too calorific but still very filling."

Eating fish and legumes 'could delay menopause by three years'
A diet rich in fish and legumes may help to delay the menopause, while eating lots of refined carbs, such as pasta and rice, may hasten it, researchers have found.
The study of women from England, Scotland, and Wales, which is the first of its kind in the UK, found the average age of menopause to be 51 and certain foods seemed to be associated with its timing.
The researchers found having a high intake of oily fish and fresh legumes - such as peas and beans - was associated with a menopause delay of more than three years. Higher intakes of vitamin B6 and zinc were also associated with later menopause.
In contrast, each eating lots of refined carbs - specifically pasta and rice - was associated with reaching the menopause 1.5 years earlier.
To explore the links between menopause and diet, the researchers drew on participants from the UK Women’s Cohort Study, involving more than 35,000 women between the ages of 35 and 69.
The women provided information on potentially influential factors such as weight history, physical activity levels, reproductive history, and use of hormone replacement therapy (HRT).
They also estimated the quantities of 217 foodstuffs they ate every day by completing a food frequency questionnaire. The food items were collated into groups according to their culinary uses. Further information on when the women had gone through the menopause naturally was gathered four years later.
In all, around 14,000 women provided information at both time points, and the final analysis included the 914 who had gone through the menopause naturally after the age of 40 and before the age of 65.
The researchers said each additional portion of oily fish and fresh legumes a woman ate per day was associated with a delay of menopause of 3.3 years. Speaking to HuffPost UK, study author Professor Janet Cade was keen to point out this does not mean menopause is delayed by 3.3 years each time you eat a portion of fish. Instead, the research looks at women’s habitual intake. For example, a woman who routinely eats two portions of fish per day will experience menopause on average three years later than a woman who only eats one portion per day.
Following the same principle, each additional daily portion of refined carbs - specifically pasta and rice - was associated with reaching the menopause 1.5 years earlier, after taking account of potentially influential factors such as weight.
Omega 3 fatty acids, which are abundant in oily fish, stimulate antioxidant capacity in the body and legumes are also high in antioxidants. The researchers have suggested antioxidants may preserve menstruation for longer by impacting the release of eggs.
In contrast, refined carbs boost the risk of insulin resistance, which can interfere with sex hormone activity and boost oestrogen levels, both of which might increase the number of menstrual cycles and deplete egg supply faster, they said.
They stressed though that the findings were taken from an observational study, and as such, more research is needed to see if food does definitely cause changes to a woman’s menstrual cycle.

These are some of the top signs of getting old
Forgetting people’s names, groaning when you bend down and falling asleep in front of the TV are among the signs you’re getting old, according to research.
A poll of 2,000 adults also found needing an afternoon nap, finding it tricky to sit cross-legged and choosing comfort over style are indicators you’re getting on a bit.
Complaining more often, declaring you’re ‘gasping’ for a cup of tea and feeling flattered when you get asked for ID when visiting a bar also made the list.
The study, commissioned by Future You to highlight the benefits of Turmeric+ tablets, also found feeling stiff and talking about your joints a lot featured in the top fifty signs you’re growing old.
A spokesman said: “It’s fascinating to see nearly half the nation considers joint pain and stiffness a sign of growing age.
“In fact, knees came out as one of the most common body parts giving Brits physical discomfort so it’s important you take care of yourself regardless of your age.”
Researchers named 41 as the age adults typically start exhibiting these signs, with 57 the point at which people consider themselves to be ‘officially old’.
While waving goodbye to their youth, 47 per cent said losing their memory is their biggest worry about getting old, with 29 per cent concerned about the impact ageing will have on their fitness.
More than one third are fretting about becoming lonely as they get older and one in five are agonising over whether they will retain their looks with age.
And nearly half agreed they feel ‘old before their time’.
But the saying “you’re only as old as you feel” is true for three in four, with more than half of adults feeling younger than their actual age.
Millions also admit to making significant lifestyle changes to try and increase their lifespan, typically pulling their finger out by age 40.
Making changes to their diet is the most popular lifestyle change with others cutting back on bad habits such as drinking and smoking or even giving them up all together.
Taking up new sports and opting to cook with healthy spices are also among the ways people try to turn back the clock.
But 28 per cent admit getting old isn’t as bad as they thought it would be.
A spokesman for Turmeric+ added: “It’s interesting to see a number of Brits are making a conscious effort to reverse the ageing process, by recognising the benefits of natural ingredients and taking food supplements.”

Telomeres are parts of our chromosomes that affect how cells
age. Like the plastic tips at the end of shoelaces, telomeres are caps at the
end of each strand of DNA that protect it and allow cells to function and
reproduce properly. Telomeres shorten each time a cell divides which, over
time, leaves genetic DNA unprotected and causes cellular function to be
compromised and ultimately leads to cell apoptosis (death) or senescence.
Every organ in the body (skin, liver, heart, etc.) is made up of cells, so telomeres are vital to good health. Slowing or stopping the shortening of telomeres can slow or stop cellular ageing.
The length of a person’s telomeres is a good indicator of
their overall health status. Having short telomeres can accelerate the natural
aging process on a cellular level. Some cells, like those found in the skin and
immune system, are most affected by telomere shortening because they reproduce
For a body to stay healthy, it is important to maintain telomere length.
Telomerase is a naturally-occurring enzyme in the body that
can slow, stop or perhaps even reverse age- and lifestyle-related telomere
shortening. Telomerase is produced only inside functioning cells; it is not
possible to take biologically active telomerase orally.
Activating the enzyme telomerase may be the key to helping cells live longer. Scientific research has shown activating telomerase in human cells slowed cell aging and allowed older cells to begin replicating again.
TA-65® is a patented, all natural, plant-based compound which is designed to help maintain or rebuild telomeres by activating telomerase. TA-65MD® nutritional supplements are the first in a line of products based on the TA-65® compound. TA-65MD® nutritional supplements are the first research-based products that specifically target Telomerase Activation.
