Are favas shell beans?

Are favas shell beans may seem a silly question but reckon on the L-dopa in the pod too.

The pods of many legumes are simply inedible no matter how young and immature you harvest them. No one would try eating the lima that way.

But the pods of many beans and peas are full of important nutrients. There's one other big advantage; not having to shell them saves a lot of time.

As easy as shelling peas is all very well but it's still tiresome.

So why would you want to grow fava beans and what's the big deal about their shells and whether you should pod them or not?

Fava beans belong to the legume family. They are rich in vegetable protein and uniquely contain an extremely important phytonutrient called L-dopa; more about that later.

In addition they are an excellent source of fibre. On the so-called industrial diet enjoyed by much of the world people are getting less than half the recommended amount; it's been refined out and actually, now that we have become accustomed to it, most of us like it that way.

What we don't like is that a diet low in fibre means an unhappy constipated tum with all the attendant risks; and a microbiome starved of nutrients. That means inflammation of our arteries, and painful joints and muscles.

Shell beans and their pods are also a rich source of some B-vitamins and in particular folate. If the elderly are deficient they become frail long before their time, and children can never reach their full potential in school.

The longevity diet stresses the importance of shell beans and it's fascinating that quite independently in all five Blue Zones they grow and relish eating favas.

Shell beans are also a very rich source of minerals like magnesium, iron and potassium; that means lower levels of toxic homocysteine, no anemia and lower blood-pressure. They are good food.

But we haven't yet addressed the question, are favas shell beans? Should we pod them or not?

Parkinson's disease

Parkinson's disease is caused by the death of specialised cells in a nucleus in the brain called the Substantia Nigra; it produces dopamine. It is a nasty condition that is terminal. Drugs helps for a few years but the benefit quickly declines.

Fava beans are unique in that they are high in a precursor called L-dopa; it can cross the blood-brain barrier and be converted into the neurotransmitter. Most sufferers of Parkinson's disease respond far better by getting treatment from their food than the medicine[1].

Are favas shell beans? Yes, they are, but there is even more L-dopa in the pod than in the seed. Young, and freshly-harvested they are absolutely delicious but you will very rarely find them in the shops; you have to grow them yourself. They have to be staked requiring a fair amount of attention, so farmers don't like planting them.


Cholesterol remains a controversial subject in nutritional circles but there is concensus that raised LDL is associated with cardiovascular disease; so statins are prescribed despite all their nasty side-effects.

Strong research shows that eating three-quarters of a cup of any shell beans every day would lower this dangerous low density cholesterol by a massive 19pc. Most of those on statins would not need them at all if they simply added to that an apple, a green salad and a breakfast of rolled oats.

Equally of importance is that the fat we eat barely affects the cholesterol levels in the blood. It's the refined carbs that are the devil; enzymes turn them rapidly to glucose in the gut which then is converted to triglycerides in the liver. They in turn are joined onto an amino acid and then transported as low density lipoprotein; bad stuff.

Simply taking out one refined starch, like a slice of commercial bread, and adding a helping of shell beans and you could probably get off statins. Do it for two months and then ask your doctor to again test your cholesterol levels.

It's unproven but favas in their shells are likely to be even more beneficial; what I can assure you is that these beauties enjoyed straight from the garden are far sweeter and creamier than starchy dried-beans.

They are also called broad-beans.

Green beans

We favour green fava beans, whether shelled or not, but obviously they are not available year-round.

The consensus is that the benefit of beans and peas greatly outweighs the so-called "antinutrients" in legumes; they do the reduce absorption of minerals but the influence can be largely limited by enjoying them green rather than dried and shelled.

Are favas shell beans? Yes, they are, but rather enjoy them green, preferably in their pods. In short, if you can find them young and freshly-harvested preferably don't shuck them.

Double-shelled fava beans

The worst way to deal with fava beans is to double-shell them. First they are shucked from the outer pod, and then the skin that surrounds the seed is removed. This is the way they are commonly eaten, but they have no fibre and the glycemic index is very high.

This is how to ruin broad beans.

Those above are whole; in their pods. In the centre you can see shelled beans.

Below are the inner beans with their skins at the lower edge of the planet; this is a very detrimental practice.

Gardeners love fava beans

Are favas shell beans? Either with their pods or after removing the seeds, gardeners love them; bacteria in little nodules on the roots fix nitrogen from the atmosphere. Firstly it is made available to the plant to synthesise amino acids, hence their high protein content, but then also into the soil for the next crop.

Nitrogen fixation bacteria enable gardeners to enrich their soil without having to use inorganic fertilizer.

How to plant fava beans is the next step; so much nicer, young and freshly harvested from your own garden.
