Food Allergies and Travel – Stay Safe and Have Fun

Food allergies and travel make a tricky combination – finding a decent meal while travelling becomes an uphill task. All the fun and excitement of visiting a new destination is marred even before you begin the journey, since you keep worrying about the crushed peanuts on the khow suey, the sour cream in tacos and every garnish on salads and soups.

It is known that more than 26 million Americans have one or the other food allergy- they may be allergic to shellfish, peanuts, milk, eggs, soy, wheat or sesame. Accommodating allergies can get really complicated when you are travelling. Add to this the fact that most of the critical food allergy reactions happen because of food that you would have consumed outside. However, you can avoid the annoyance and strain if you can keep a few things in mind when planning to travel.

Check all your stops first

Scrutinize the menus of all hotels and restaurants on your itinerary and check what they serve. Also look up eateries near the tourist spots that you plan to visit and identify the ones that serve suitable food for you. Also check for medical facilities for food allergy awareness and doctors in your travel destination who can be trusted to treat allergic reactions.

Carry some food for yourself

You will need a doctor’s note, and you can carry almond milk, apple sauce, peanut butter along with enough snacks, especially if traveling with kids, to keep those hunger pangs at bay while you are dealing with flight delays or are yet to reach a suitable restaurant.

Carry your meds

This goes without saying – epinephrine is considered a medical necessity by TSA and is allowed to be carried on flights. Carry the injectors with other liquids you need to produce for inspection, and also inform your flight attendant about the same if you are traveling alone. Flight attendants are trained to use them; they know how food allergy occurs and can help you in case of food allergy symptoms or sudden anaphylaxis.

Make the security check worth it

You may need extra time at the security check for carrying all that food, but with a doctor’s certificate, you should be able to carry it all in, as long as you comply with food allergy guidelines. So make sure you arrive at the airport well in time to show all the necessary stuff to TSA agents.

Say no to the in-flight snack

Airlines often serve peanuts as in-flight snacks, but you must not only skip that, but also try and contact the airline in advance, or a gate agent before boarding the flight and request to have your seats and surroundings cleaned to remove any traces of peanuts (even peanut dust) and to have the flight attendants announce and request passengers to refrain from opening any snacks that contain peanuts during the course of the flight. Most of them would know what food allergy looks like, and will oblige without much fuss.

Don’t lose it in translation

If you are traveling to a place where a different language is spoken, carrying a translation card along with a food allergy chart is a good idea. Restaurants in different places use different varieties of ingredients, and you must let them know (in their language) that you need to avoid some of them.

Practical and doable, these tips will ensure that you have a safe and fun-filled holiday!

Why Allergy Finder?

Something we see a lot on twitter and even in our discord is “no one cares about the allergy finder app, no one will use it”. That’s a fair assumption from a cryptocurrency centric viewership but it’s also very nearsighted. Something we have learned in the last 5 years with Expanse is that the crypto industry has a painfully short term memory and an even shorter attention span that moves in cycles. In order to hedge the draining bear markets and provide an external revenue stream of USD, we have focused on a non crypto project. We landed on Allergy Finder because millions of people annually suffer from some form of allergy or food sensitivity. Oftentimes these allergies and sensitivities go under-diagnosed and under treated leading to a decreased quality of life and a dependency on harmful medications. 

Americans spend on average $2B/year on antacids alone. Our research has concluded that is just the tip of the iceberg. Americans spend another $2B/year on anti inflammatory nsaids, and $42B on treating hypertension. The allergy finder we have developed could not only treat these patients but cure them. We are offering a potential cure that could disrupt a $100 billion dollar a year industry. Imagine if we capture just 5% of that industry. What would that do for Expanse? Imagine the allergy finder app in every home in america, helping people consume the RIGHT medication at the right time. Imagine preventing others from eating foods that could give them a heart attack, and lastly saving lives in numerous ways while improving billions of people’s quality of life. What is that worth? What could that sort of cash flow do for Expanse?

Below is an article further highlighting why we have decided to disrupt this specific industry.

ExpSwap Team Update

The DEFI Team has been working on its own version of UNISWAP connected to the Expanse Network in this process the challenges have been interesting but most have been overcome by this team.

At Expanse we are committed to supporting the teams whom wish to build on our platform, we are supporting with configuration parameters and with the image and branding of the portal to follow the graphic line of Expanse.

ExpSwap is based on the Uniswap Automated Liquidity Protocol which is a fully decentralized protocol for automated liquidity provision on Expanse. A simple formalized equation drives unstoppable liquidity for thousands of users and hundreds of applications. This empowers developers, liquidity providers and traders to participate in a financial marketplace that is open and accessible to all.

This will be the tools available for ExpSwap

Just like the way Uniswap did the team is creating the same functionalities:

  • An SDK to get started with ExpSwap: A step-by-step guide to getting started building interfaces with ExpSwap.
  • A Smart contract development: Simplify the process of integrating Expswap into your project.
  • Introduction to Flash Swaps: Withdraw the reserves of any ERC20 token on Expswap and execute arbitrary logic.
  • Introduction to Oracles: Highly decentralized, manipulation-resistant, on-chain price feeds.

3 Basic and Important Questions

What is Expswap?

Expswap is a protocol for exchanging ERC-20 tokens on Expanse. It eliminates trusted intermediaries and unnecessary forms of rent extraction, allowing for fast, efficient trading. Where it makes trade offs decentralization, censorship resistance, and security are prioritized.

How does Expswap work?

Expswap is an automated liquidity protocol. In practical terms this means there are template smart contracts that define a standard way to make liquidity pools and corresponding markets that are compatible with each other. There is no orderbook, no centralized party and no central facilitator of trade. Each pool is defined by a smart contract that includes a few functions to enable swapping tokens, adding liquidity and more. At its core each pool uses the function x*y=k to maintain a curve along which trades can happen.

How are prices determined?

Prices are determined by the amount of each token in a pool. The smart contract maintains a constant using the following function: x*y=k. In this case x = token0, y = token1, k = constant. For each trade a certain amount of tokens are removed from the pool for an amount of the other token. To maintain k, the balances held by the smart contract are adjusted during the execution of the trade, therefore changing the price.

Status of Expswap 

Early this week the team said:

“Yes we have read the conversation and the pressure we have. The update about the uniswap is that we have deployed all the uniswap contracts on expanse mainnet. Now we are just trying to fix some issues on the uniswap interface. We are having some errors on the uniswap interface regarding connecting with the expanse main node. As soon this will be fixed we are good to go IA. We are trying our best to finish this asap. ”

The developer in charge of the development of Expswap gave us this update today 09-15-20:

“We have deployed all the smart contracts of uniswap on expanse mainnet. Now we are working on uniswap interface customization to make it run for expanse network. Currently, we have fixed the issues of interaction with deployed contracts but still we are facing some issues regarding the token mappings. We are actively looking into providing a customized list of tokens in order to resolve the problem.”

But something amazing happened

Early this week Christopher Franko share on the Discord Channel:

“We have another team working on another exp defi project. One team is working on uniswap, the other is working on a sushi fork. This is going to get interesting!

It’ll be interesting to see what happens. I wonder if they can be LPs for each other.”

“They are working on adding defi projects to expanse and to help facilitate cross chain transactions that help alleviate congestion on other networks.”

Tablet Version for Allergy Finder is in QA

The Allergy finder team has made significant progress this month.The latest, in a series of exciting updates, is the introduction of the tablet version for the Allergy Finder App. This new version will be released this week and it will be available for IOS and Android tablets. 

Allergy finder is a platform to record all your meals, symptoms and allergic reactions in a very simple way. Keep an orderly diary of your allergic reactions. In addition, you can help others by registering products and their content. You can now download our app in stores for phone and tablet. 

The Allergy Finder app is a community-powered, subscription-based app where Gamification plays a major role in the app and active participants will be rewarded with points that can be redeemed for products and services.


Here is the Design for the Allergy Finder tablet version. 

The GEXP Update to 1.19.20 is ready

Recently our team work on this GEXP Update to the 1.19.20 version 

Geth v1.9.20 is another maintenance release containing bug fixes and security enhancements. This update is recommended for all users.

Please note that reverting to Geth v1.9.19 or prior after upgrading to v1.9.20 is not possible without a resync because the blockchain database layout has changed.

Build Changes:

  • This release is built with the new and shiny Go 1.15 compiler version
  • The Ubuntu PPA now contains builds for Ubuntu 20.10 Groovy Gorilla. Ubuntu 19.04 Disco
  • Dingo is no longer supported.

What is an allergy?

50 million Americans are allergic to something. Yes, allergy is that common. Be it pollen, food or animal dander, there are plenty of such allergens around us causing different types of allergies that include allergic rhinitis, asthma, food allergies, insect venom allergy, drug allergies, latex allergies, eczema, allergic conjunctivitis, chemical sensitivity, and so. However, among all the types of allergies known, food allergy is one of the most common allergies. 

Food Allergies

Food allergies are common. However, they are not the same as food poisoning or food intolerance. Food poisoning occurs when you become ill after consuming spoilt food whereas intolerance is when the body is not able to digest a particular food type. For example, lactose intolerance is a common food intolerance where the body is unable to digest lactose. On the other hand, food allergies occur when the body’s immune system identifies a particular food protein as an allergen or a potential threat. To combat this foreign substance, the body produces specific antibodies and releases potent chemicals, like histamine. As a result, you develop symptoms like itching, swelling, coughing, wheezing, and in severe cases, a life-threatening condition called anaphylaxis. 

Common food allergies and allergens

Does your nose start running the moment you have hot spicy food? Do you get diarrhea if you eat cheese? These are common food reactions that many of us develop mostly due to food intolerance. Food allergy occurs when the body’s immune system identifies harmless food as allergens or foreign substances and starts reacting to it. From mild skin rashes to swelling of lips, and gasping for breath in severe cases are common signs of food allergies. Although they are serious, you can manage food allergies. Here are some of the most common food allergens

  • Milk (mostly in children)
  • Eggs
  • Peanuts
  • Tree nuts, like walnuts, almonds, pine nuts, brazil nuts, and pecans
  • Soy
  • Wheat 
  • Fish (mostly in adults)
  • Shellfish (mostly in adults)

Some food allergens may cause allergic reactions in some individuals although these are rare:

  • Corn
  • Gelatin
  • Meat – beef, chicken, mutton, and pork
  • Seeds, often sesame, sunflower, and poppy
  • Spices, such as caraway, coriander, garlic, and mustard

Common symptoms of food allergy

Allergic symptoms can be from mild to severe. Symptoms may appear immediately after eating the food or hours later. Watch out for these signs to detect food allergy:

Mild symptoms 

  • Skin rash
  • Itching
  • Red and swollen skin
  • Itchy mouth and ear
  • Runny or stuffed nose
  • Sneezing and dry cough
  • Throwing up
  • Stomach upset and stomach ache
  • Diarrhea

Moderate symptoms

  • Swollen lips, tongues, throat
  • Chest pain and uneven heartbeat
  • Trouble breathing and swallowing

Severe symptoms

In severe cases, a food allergy can become life-threatening which is known as anaphylaxis. People who have asthma are more prone to develop anaphylaxis from food allergies. If you are prone to it, your doctor may suggest you to carry epinephrine injectables.  

Know about the hidden triggers

The best way to avoid a food allergy is to avoid the food. For this, you need to identify the hidden triggers. For example, if you are allergic to egg, know the ingredients before consuming a piece of cake or a cookie because it might contain eggs! Similarly, if you are allergic to milk protein, know that a piece of hotdog may contain milk protein. 

How many people have food allergies?

As we already mentioned, food allergy is extremely common. Researchers estimate that 32 million Americans have food allergies. Studies published in 2018 and 2019 estimate the number of Americans of all ages who have convincing symptoms of allergy to specific foods:

  • shellfish: 8.2 million
  • milk: 6.1 million
  • peanut: 6.1 million
  • tree nuts: 3.9 million
  • egg: 2.6 million
  • finfish: 2.6 million
  • wheat: 2.4 million
  • soy: 1.9 million
  • sesame: 0.7 million

While most children outgrow food allergies, for most adults it is incurable. However, a food allergy can be managed by avoiding the particular food. Reach out to your doctor immediately if you develop symptoms as mild symptoms may become severe and life-threatening at times.  

It is also advisable to keep a diligent record of your meals. This will help you analyze the foods that you eat, along with any symptoms you might experience once you have consumed the food. Such a food diary will help you take charge of your health.

Alex club token on Expanse

Recently on the Expanse Telegram our User Alex shared his experience with Expanse here is the conversation we had (you can look for it on July 17th 2020):

  • Omar: Welcome to all of our new users to Expanse. 

Alex: IMHO, as a user of our token based on Expanse, we like our currency for its efficiency and low cost of Tx. Compared to ETH where we’d have to spend a substance of money to pay for TXs and this is not desirable.

  • Omar: Yes!! We have low transaction costs.

— Alex:when we started tokenizing our club services in 2017 we’d agree to pay 1-2 cents for a Tx;  that’s why Expanse was a selection. Even cheaper now,  and even of course that we don’t run a scale of a million TX of our token, it’s still a reason why.

  • Omar: I will love to share your project in our next Newsletter. Will you agree on it?

— Alex: Sure, to share experience is great. We currently minted 41,600,000 mo’s and they are our club’s internal way of paying for the club’s services. So now around 160 people use mo’s. So our people have the smart contract to exchange their mo’s for Exp. That’s great thing because another way of liquidity is asking to pay money and that’s we decide say it’s ok or it’s not ok, but with a 24/7 exchange at the smart contract and perhaps a new Luna wallet our people wouldn’t need our consent for acquiring tokens and beginning use the club services.

  • Omar: That is amazing!! I will DM you so we can talk about it and thanks for this

— Christopher Franko: Man that is really awesome and heart warming to hear

— Speedrunner: [In reply to alex] Can you share contract address of your token?

— Alex: I will. First I want to say “thank you” to Chris . Never had a chance,  and being polite is better here and now. Thank you for the Expanse from all our club people. We will keep using it as our basic CC.

— Alex: var tok =“0x019d04fc548fb7813a4132082c5ce87998094ac7”);

— Speedrunner: Cool, thanks

— Alex: No sure if relevant as the Health App. – relevant to sports, anyway. That’s the club that uses “mo” token. People there are real recreational tennis players. The club services are a) creating an offer of a match on the club board  (600 mo) b) publishing a match result (600 mo) c) participation in a tournament (~10 kmo). Both money and tokens are acceptable with equivalent of US0.45 per one offer/match result, if paid in RUR,  – and 600mo=8Exp ~ US0.24 – so that its 40% discount per match if paid in tokens.

About the Franko’s Vision, Alex said:

— Omar Alvarez: This is our founder’s vision, what do you think?

— Alex:  I think that Expanse is great for tokenizing public services especially the same services offered to the public for money. 

Example, universities (U) may have begun already offering their own tokens for their students and staff to pay for the internal U services, at lower rate if compared to payments in money. I mean that a U can afford a discount to those students and staff members who chose to pay with tokens instead of money. 

This discount is based on ability to sell/buy tokens at a smart contract independently and individually, so when each person involved at U can choose whether to pay immediately with a card at 100% or buy tokens at a smart contract for Exp at 50% and then pay with tokens. 

Considering all  arising opportunities a U gets from both parallel payment methods and a low cost of acquiring crypto services with Expanse, this looks like a big new field.

Franko’s self reflection

Five years ago

When the founders of expanse got together to plan out launching the network we knew that it would be tough. I mean, it was just three of us, a small team with huge ideas. We were ambitious but didn’t have much money, but we recognized there was a need in the market that we could fill so we launched EXP anyways. Armed with nothing but our ideas and experience in the Industry we designed our networks parameters around incentives.

To be more specific, what initially set us apart from the ethereum codebase that we forked was our lack of funding, a valueless reserve of newly minted magical internet money and our drive to give it all value. And so it was. Within a few weeks of our initial launch people resonated with our ideas and saw our potential. We were quickly listed on all the big exchanges, and finally we were worth a few cents each. But then the market fell flat like they often do after the initial shine wears off.

For the first 6 months the three of us didn’t even take our agreed upon allotment of the reserve and we worked. We kept working. Pitching our ideas, drafting new ideas, scraping old ideas, throwing everything we could at the wall to see what stuck and we did more of whatever that was. There is this sentiment in the industry that if you’re failing that you are just trash. That couldn’t be further from the truth. As Elon Musk once said, I’d you aren’t failing then you aren’t innovating. And so we failed.

Then something miraculous happened and we finally achieved what felt like true success. We became one of the fastest rising coins on the market. In one day alone we rose 30,000%. Nothing in the history of crypto has ever risen that fast ever. But like everything in crypto, the fun never last. Because markets and dev cycles rarely correlate. The market is hungry for stories, ideas, with implementations as an afterthought. And new and better stories and ideas came out. And after reaching a crescendo it was time to continue failing, and so we did.

I’ve shared this story to remind you that it’s not our failures that define us but the will to defy. We are defined by the will to keep working, and coming up with new inspiring stories, ideas and to sculpt those into actions and products that add value to people’s lives. I’ve shared this story to show you that we are on the precipice of something truly unique and sustainable, all it takes is you.

For the last 5 years it was the small dev team daring to defy our places in the world by competing with giants. But we made a few oversights. Maybe it was inexperience, naivety or arrogance but we overlooked a few things. 

One, we didn’t implement and incentivize standard practices and communication pathways common in open source communities. Two, we had a difficult time crystallizing and communicating our goals to the community, three we did a poor job at distinguishing ourselves from our competitions and  lastly although our reserve has lasted 5 years we didn’t consider a sustainable future where the reserve couldn’t sustain development any longer.

But now it’s time to take our next step in our evolution. It’s time to work together to create a unique sustainable solution that sets us apart from the competition.
