If you eat farmed fish now then you've nothing to lose
In a mere five years, lab-grown salmon will be on the sushi conveyer-belt, at least if a number of startups have their way. Well, they will have their way. Like the coronavirus vaccine, it is only a matter of time.
In fact, Finless Foods was hoping to bring its cell-based bluefin tuna to market by the end of 2019. Although it hasn't entirely made it, it is very close and has served small select audiences its early production lab-grown shrimp.
WildType, a startup making lab-grown salmon, has opened up a pre-order list for select chefs. Although the company is as much as five years out from commercial production, according to founders the company is looking to partner with chefs who want to incorporate WildType's sushi-grade salmon product into their menus.
Could these lab-based meal creations be better for us than the real thing, and would you eat it? You might be surprised.
If cutting them out is impractical, try this alternative
The association between Ultra Processed Foods (UPF) and poor health outcomes is well established, even if the mechanisms are not. A recent global study identified the principal components of UPFs that are most negatively associated with those health consequences.
If we know what those components are, then we can take steps at an individual level to improve the quality of our diet. There were two clear answers which we can use to inform our choices.
How you peel it makes a difference!
Avocados might be the last thing you would consider would help you lose weight, but you'd be wrong. Not only can they help you lose weight, but they also improve your heart and brain and eyes, and can rejuvenate your skin.
And their effects are even more beneficial if you are older. When we're older, we need more metabolic repairs done inside and out - and avocados are the perfect food to help.
I eat a half-avocado every day. I lace it with other goodies such as turmeric, ginger and apple cider vinegar. But putting those aside, whatever you do with avocado - chop it, slice it, mash it, mix it - it has an astounding range of nutritional benefits, including:
Nutritional timing and choice for a good night's sleep
In this time of the pandemic increased stress levels are interfering with the quality of our sleep. Poor sleep often leads to a poor day, and we enter a cycle of stress which is hard to break.
A good diet can go a long way to restoring better sleep and breaking the COVID stress cycle.
Do these 4 things to kick-start your weight loss
Dieting is confusing, especially when what works for your best friend doesn't work for you even when you know that you've been just as diligent. Guess what? Scientists have discovered that your gut plays a massive role in the success of dieting.
I didn't understand the caffeine load in tea
Having felt uncharacteristically sick for more than a week, I saw my doctor this morning. He ruled out everything except something upsetting my gastrointestinal tract, and he took notice when I said I'm drinking a lot more tea.
I'd never thought about tea and caffeine and any side-effects. I knew that it had caffeine, but I associate coffee with excess caffeine - I even wrote a post about it not so long ago.
I'm drinking more tea since I learnt this
Tea is the most widely consumed beverage in the world after water and is a major source of dietary flavonoids. Yet surprisingly, the way in which tea supports our health is still unknown (June, 2019).
If you don't yet drink enough tea (I don't) then perhaps it is time to take up the habit. Here's why.
For centuries, tea has been anecdotally linked to digestive health, and research studies have convincingly associated consumption of black tea with reduced cardiovascular risk. This benefit is attributed to substances called polyphenols, such as catechins.
Breakdown of black tea improves our gut biome
Polyphenols are also in other (non-black) teas and in orange skin, for example. What's different about the black tea polyphenols (BTP) is that they are heavier molecules and can resist breakdown in our stomach. In other words, BTPs are too large for direct bioavailability for our metabolism - like some fibres which are not readily digestible in our stomach.
It takes the power of our colon break down these big boys, and when that happens, other magic happens associated with our gut biome.
The microflora in the colon bioconvert the BTP to make the polyphenols available to other parts of our metabolism, and concurrently this breakdown improves gut microbial diversity.
Hence, BTPs give us direct benefits associated with polyphenols from their anti-inflammatory and blood pressure-lowering properties. They also give us indirect benefits from the byproducts of breaking down in the gut, such as improvements in platelet and endothelial functions (which may be why black tea benefits diabetics).
The interaction between the gut biome and the rest of our body is still far from understood. Humans are superorganisms, and the gut is part of our super-complicated system of how we stay healthy. Some studies suggest that the BTPs are even more effective when they are digested in conjunction with fibre and especially prebiotic fibres as in bananas.
Nine reasons to drink tea plus one more for the brain
Tea's benefits are all great news for tea drinkers because black tea offers such an impressive array of benefits - including:
Also, evidence continues to emerge that tea may act to improve cognitive function. For example, a study showed that green tea increases brain activation in a key area that improves immediate language processing and short-term recall. Other research suggests that tea polyphenols may be useful for the prevention or treatment of various neurodegenerative diseases.
For smokers, however, it has been found that black tea does not confer many of these benefits. If you smoke, this is one more important reason to quit.
How many cups should we drink daily?
What we need to know is what "dose" is effective? Some studies have not found beneficial effects, and this has been put down to too low a dose of black tea.
We need to know the "physiologically relevant dosage". We are looking for long-term persistent results, not just directly after drinking tea.
In a study of dose, two healthy volunteers drank 4 cups of Lipton green tea every day for four days. Tests recorded levels of BTP, and its byproducts which were sufficient to activate the associated benefits.
You want to get the most benefits without overdoing the caffeine. Therefore, consider drinking between 3 and 6 cups of tea per day. No sugar of course! Added sugar will do more damage than the benefits of the tea.
I mix green and back in the one pot and drink 4 to 5 cups a day. I also cheat a little by emptying a teabag into my oats each night, which I then heat and cool to make them prebiotic. That way I get the fibre as well as the tea BTPs.
Good luck. I'm off to have a cup of my mixed tea with lunch.

Here’s why, and how to fix it
Vitamin D is free - from sunshine, yet amazingly vitamin D deficiency is the most common nutritional deficiency worldwide (2019).
This deficiency is terrible for our health, and neglectful, considering how easy it is to get the optimum dose.
Including helping maintain healthy blood pressure
High blood pressure is a leading cause of cardiovascular disease in developed countries. Yet some countries, such as Italy and Japan, have low rates of high blood pressure and lower mortality rates due to CVD.
That's not because they all go to the gym 5 times a week or due CrossFit. The reason is far less complicated and available to everyone.
They eat more fruit and vegetables, and in particular more nitrate-rich vegetables.
50-percent of the health benefits are from the skin
In the Western world, citrus peels are mostly just byproducts of juicing and treated as waste. That's a pity, as they contain many phenolic compounds which are proven to be beneficial to our Western lifestyle and diet-induced diseases.
By consuming the whole citrus fruit, we gain far more health benefits than by just eating the flesh. There are more health benefits from compounds in the skin and membranes than from just those in the flesh.
The compounds in the non-flesh parts of oranges are so powerful that in some parts of the world they are used as traditional medicine to cure fungal and bacterial infections, human colon and breast cancer by alternative therapists.
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
