And even better if at stage 5 of ripeness ...
Who would have thought that bananas promote our gut health, helping grow beneficial bacteria that ultimately strengthens our bones and delays neural degeneration in our brain?
It all starts with inulin, which is in bananas and which begins digestion only when it reaches our gut.
Free radicals age you prematurely
It's said that our skin is a window into our inner health.
That may not be true for marathon runners, whose skin belies their inner fitness. For others, naturally healthy-looking skin says something about how we take generally care of our health.
For skin, damage prevention is the number one strategy. We need to prevent damage from the sun and the environment, and damage from poor food choices.
Protects your brain and reduces your wrinkles
We know about the immune-support properties of vitamin D, currently the subject of many studies examining its ability to help our immune system resist Covid19.
We know about the antioxidant effects of vitamin C, and vitamin E, both of which limit the impact of free radicals and reduce chronic inflammation.
(Antioxidants neutralise free radicals which are molecules that cause cellular damage when their levels become too high. Damage caused by free radicals is associated with numerous chronic conditions, including cancer, heart disease, and diabetes.)
Asparagus ranks as an excellent source of both vitamin E and vitamin C. It is also a good source of a vitamin which you have probably never heard of before - vitamin P.
In fact, vitamin C and vitamin E work synergistically to enhance the antioxidant effects of vitamin P.
Weight loss and late-night meals ...
In nutrition (and fitness) it's hard to differentiate between fact, myth and personal bias.
And boost your brain health
The choices you make at the grocery store can have an impact on the inflammation in your body. Scientists are still unravelling how food affects our inflammatory processes, but they know a few things.
In simple terms, sugary high-processed foods help release inflammatory messengers that can raise the risk of chronic inflammation. Other foods like fruits and veggies help your body fight against oxidative stress, which can trigger inflammation.
Add walnuts to your shopping list - they fight inflammation and have other desirable side-effects such as helping us sleep better.
After one week this is how you'll feel
Most adults don't eat enough fruits and vegetables. In fact, dietary intake of several nutrients found in fruits and vegetables — including potassium and dietary fibre — is low enough to be a public health concern for both adults and children in the US, and in Australia.
"The bottom line is that most Aussies are not eating enough vegetables each day," Alexandra Parker, accredited practising dietitian of The Biting Truth, told HuffPost Australia.
The health consequences can be serious. For example, there is compelling evidence that a diet rich in fruits and vegetables can lower the risk of heart disease and stroke.
A study of over 100,000 mean and women over 14 years found that, compared with those in the lowest category of fruit and vegetable intake (less than 1.5 servings a day), those who averaged 8 or more servings a day were 30% less likely to have had a heart attack or stroke.
Although all fruits and vegetables likely contributed to this benefit, green leafy vegetables, such as lettuce, spinach, Swiss chard, and mustard greens, were most strongly associated with decreased risk of cardiovascular disease.
What's perfect is to fill half your plate with vegetables at all main meals. That may not sound very scientific, but it is a whole lot better than worrying about the details.
Add in variety and a couple of pieces of fresh fruit, and you will start to feel the difference. That's all I do - I pay attention to mixing the colours, eating 5 or so serves daily, and eating some fruit.
How you do that starts with shopping! Typically, in this kind of article, we jump into the health benefits, and what should go onto the plate.
Not in this case! Let's start at the shop.
And add some fenugreek seeds ...
Is coffee good for you? It could be, in moderation.
Coffee has had a hot-and-cold reputation when it comes to health benefits. Not long ago, I was learning about the dangers of coffee: how it could raise your blood pressure, make your heart race, impair sleep, and maybe even cause bladder and pancreatic cancer.
Now, it seems that drinking two to five daily cups of coffee may protect against heart disease, diabetes, and some cancers.
But too much can cause problems like anxiety, nervousness, and insomnia.
And if you like Japanese food ...
Our body needs vitamin K to produce prothrombin, a protein and clotting factor that is important in blood clotting and bone metabolism, and for regulating blood calcium levels. That is how we usually pigeonhole vitamin K.
However, vitamin K's health benefits have been recently shown  to extend beyond blood and bone health and to benefit chronic low-grade inflammatory diseases such as cardiovascular disease, osteoarthritis, dementia, cognitive impairment, mobility disability, and frailty.
There is also interesting, though not definitive, evidence of a direct correlation between vitamin K levels and cognitive performance. Four human studies reported an association of low vitamin K intake or low blood concentrations of vitamin K with cognitive impairment or Alzheimer's Disease.
Perhaps. But overdosing will damage your kidneys
Scientists in the UK are calling for ministers to add vitamin D to common foods such as bread and milk to help the fight against Covid-1.
However, the call is controversial.
Back in 2017, Professor Louis Levy, Public Health England's head of nutrition science, responded to calls for fortification by saying that there was not enough evidence that vitamin D would reduce the risk of respiratory infections.
Recently, researchers in Spain found that 82% of coronavirus patients out of 216 admitted to hospital had low vitamin D levels. The picture is mixed; some research shows that vitamin D levels have little or no effect on Covid-19, flu and other respiratory diseases.
Here's how the top vegetables stack up
Vegetables are essential for well-balanced diets for their high load of vitamins, minerals, dietary fibre, and phytochemicals.
Right now, with the pandemic still active, salad vegetables play a more vital role than ever in our diet because of their capacity to improve our immune defences.
They're also convenient since we can eat them as raw, so they present little challenge in preparing for our everyday meals. For example, a cold dish of various raw vegetables, seasoned with oil, vinegar or other dressings, can be quickly prepared.
Just how vital are salad vegetables in our diet to overcome viral infections?
Since I was diagnosed at 50 with Type 2 diabetes I've been learning how to do bone-building fitness training which lowers my age. You can too. It's your choice. Walter
