All about fruitarianism with a long-term fruitarian, Lena

Fruitarianism

Fruitarian ethics, history, worldview and ideas - theoretical and cultural aspects of fruitarianism, fruitarian lifestyle and diet. 

Fruitarianism - a quest for optimal ethical ways to live and healthy diets based on fruits and seeds. 

Notes: current

It has been seven years since I tried to find researches or philosophers who might be interested in fruitarianism. Back then I have joined ResearchGate.net but nobody seemed to be involved into anything close to fruitarian diet or ethics. I left this note on my profile (researchgate.net/profile/Lena_Nechet):

Hi, I have joined this site for scientist (not being one myself) to find someone who is interested in researching nutritional aspect of fruitarianism. I hoped someone would be interested in a case study. I gave up, maybe too early. I'll keep this profile for the history, without participation, but you are welcome to contact me directly - thank you!

I am not as eager anymore to offer my time for this purpose, but I will definitely consider serious offers.

Fruitarian Salad - a somewhat complex non-sweet fruit salad recipe, with my usual spices and herbs, and with some additional ingredients this time like chives, oregano, sage, thyme, marjoram, basil, rosemary, etc. - raw vegan, for Winter and cold - a 30-minute improvised video:

Hope you liked some of my ideas and got your own!

Some fruitarians maintain that fruitarian diet should include only fruit flesh, which usually surrounds seeds of the common fruits. They insist on nver including seeds, because eating them would mean the same as destroying plants (or their "babies").

I must disagree

  1. First, seeds are not developed organisms. The main premise of fruitarianism is that complex organisms as plants deserve our ethical consideration, and most seeds are just dormant plant matter: it would be highly impractical and even immoral to treat them as individuals. 
  2. Second, they are produced by plants in excess, not all require to go through our digestive system, and only few can develop into organisms due to shortage of resources on this planet.
  3. Third, fruitarianism is about fruits is botanical sense, not culinary or common.

This is amazing how many times I was asked: where do you get your protein? Many people seem to think that there is no protein in fruit. Let's look into it. 

  1. How much protein one needs? ↓
  2. How much protein is in fruit and seeds? ↓
  3. Is that the right protein? ↓

I composed two lists with a few examples of the fruitarian food sources of zinc: fruits, seeds, seaweeds and mushrooms. You can compare the amounts of zinc in them with the recommended daily allowance of the mineral. RDA is usually around 20% higher than the amount needed for half of the healthy people.

Protein Structure, Cooked and Denatured Proteins

Proteins are chains of amino acids. The sequence of amino acids in a chain is known as the primary structure of a protein. The chains fold up to form complex three dimensional shapes. The chains can fold on themselves locally (secondary structure) and wrap around themselves to form a specific three dimensional shape (tertiary structure).

The secondary / tertiary structure of a folded protein is directly related to its function. For example, enzymes are proteins that catalyze reactions. They have binding sites that interact with other molecules. These binding sites are created through the folding of the amino acid chains that gives rise to the three dimensional shape of the enzyme.

Denatured Protein

Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures. Since denaturation reactions are not strong enough to break the peptide bonds, the primary structure (sequence of amino acids) remains the same after a denaturation process. Denaturation disrupts the normal sheets in a protein and uncoils it into a random shape.

Denaturation occurs because the bonding interactions responsible for the secondary structure (hydrogen bonds to amides) and tertiary structure are disrupted. In tertiary structure there are four types of bonding interactions between "side chains" including: hydrogen bonding, salt bridges, disulfide bonds, and non-polar hydrophobic interactions. which may be disrupted. 

Proteins can be denatured through exposure to heat or chemicals. Denatured proteins lose their three dimensional structure and thus their function. 

Digestion of Proteins and Cooking

Protein digestion begins in the stomach, where the acidic environment favors protein denaturation. Denatured proteins are more accessible as substrates for proteolysis than are native proteins. The primary proteolytic enzyme of the stomach is pepsin, a nonspecific protease that is maximally active at pH 2. Thus, pepsin can be active in the highly acidic environment of the stomach, even though other proteins undergo denaturation there.

Heat disrupts hydrogen bonds and non-polar hydrophobic interactions. This occurs because heat increases the kinetic energy and causes the molecules to vibrate so rapidly and violently that the bonds are disrupted

Foods are cooked to denature the proteins to make it easier for enzymes to digest them. Cooking food denatures some of the proteins in it and makes digestion more efficient. Heating to denature proteins in bacteria and thus destroy the bacteria.
