Personalized nutrition - Could genetic tests improve your health and your figure? | DW Documentary

Carbohydrates, fats, proteins. Each person is different, and every body utilizes food in a different way. That’s why a personalized diet can help you lose weight, and give you more energy.
Now, scientists around the world are working on a precision formula tailored to the individual. Can DNA tests and analyses of the microbiome determine the ideal diet for each person’s health?
Many people know that elevated blood sugar levels can lead to obesity and trigger type 2 diabetes mellitus. "Far less well known is that, for each person, different foods drive up blood sugar levels," says Prof. Christian Sina, director of the Institute of Nutritional Medicine at the University Hospital of Schleswig-Holstein. "It makes no sense to divide foods into 'healthy' and 'unhealthy' across the board. Rather, people should be divided into different categories, in order to find out what each individual personally tolerates best."
This research has its foundation in Israel. At the Weizmann Institute of Science in Rehovot, Professor Eran Elinav developed an algorithm that uses stool sample analyses to create individualized dietary recommendations. The algorithm is now part of a nutrition app used by more than 70,000 people.
DNA analyses to create personalized diet plans have been available in Germany for several years, but consumer advocates and scientists have criticized the approach, saying it lacks evidence.

Individualized nutrition is the future! We hope that more people are able to access to tests like these in the future

[@portiagriffey4403]

Are people generally aware what foods make them feel good (do they know their own bodies without tests)? For me (maybe because of my migraines - I am sensitive to which foods spike my sugar levels (no alcohol ever, no rice, bread, potatoes instead pulses, oats), I know which foods make me feel good - energetic and which foods make me feel bad - lethargic). I've always joked I am a 20 stone person waiting to escape because given a spike in sugar levels just makes me want to eat more! With my twin brother already being pre diabetic my doctor says I need to be careful. I see in my sons their need to be careful with their diets. I am stubbornly 3kg overweight. Being strict with my diet has really helped my migraines. ps. I drink a lot of coffee ! with no effect. Your documentary was very interesting. Until these tests are available - can people listen to their bodies?

[@WiseMindNutrition]

@@portiagriffey4403 The individualized testing certainly gives a lot of clues that are hard (if not impossible) to figure out without them. While one could (in theory) find their food intolerances through elimination diets, many don't. The process can also be extremely difficult, alienating, expensive, and triggering for disordered eating. So many factors are involved in feeling our best/ finding solutions. For myself (Maria here!) I was able to determine my food migraine triggers because they are common ones (aged cheese, red wine, cured meats), however I still get occasional migraines so maybe there are other foods I havent figured out yet. Or it could be a different trigger entirely. Others on our team have found relief from eczema only through food sensitivity testing. Bodies are tricky! Science can help :)

I hypothesized that the incidence of gallstones in people of indigenous ancestry in Peru was due to the drastic change from a very low-fat diet to a high-fat diet, which happened in a very short generational time. The numbers of people who have cholecystectomy don't lie. These studies make me think that there is definitely a relationship. The information about what we eat and what works to keep us alive is stored in our genome and passed on to offspring. By the way, I'm one of those numbers.

It is good to see someone actually studying the effects rather than just saying something because they know so. I have had type 2 diabetes a little over 10 years now. When I first got it I saw some HORRIBLE - DANGEROUS doctors without any actual training giving advice and recommending too many drugs. I started keeping records of diet, exercise etc. I had one doctor absolutely refuse to look at any of that. I did figure out what I could and couldn't eat though. During that time I found out about the fact that Protein becomes Glucose if eaten in excess. The Keto diet has some good points, but is too heavy on Proteins.

[@anandananda9515]

You don't need to consume excess protein. "Because protein is digested slowly, its impact on blood sugar is relatively low. Additionally, carbohydrates break down directly into glucose, while proteins are broken down into amino acids, which take time to be converted into glucose." I have polycystic ovary syndrome and I gained excessive weight, I tried several diets to lose weight, in addition to 2 hours of physical activity. I'm on a carnivore diet, after 2 months my high insulin levels dropped by half and high andeogens reduced significantly

[@jarikjayhil]

I did Keto when I was over 135 kg, lost weight in the beginning but I transitioned into something more modified. I was eating less starch but not eliminating it, protein was moderate, but more whole foods like veggies and fruit. I lost more weight and felt better. Keto has some good points, but I'm still shocked that people I know that do it eat heaps of red meat, bacon, and not enough vegetables.

[@3naturalBionutrition]

It is reversible. After 10 years at a minimum you should be in the pre-diabetic category.

[@3naturalBionutrition]

​@anandananda9515 ALL carbs do NOT directly breakdown into glucose. This is applicable for simple carbs only.

[@wendyscott8425]

@@jarikjayhil Red meat and bacon make the world go round. :) I've been on a keto diet for years although I do break it on special occasions when I eat things like cake and ice cream only in very small amounts. So far, so good. I lost 40 pounds and have kept it off. I also have avoided diabetes, which my A1c test shows is borderline prediabetes (whatever that is) but hasn't gone up in years. My new doctor actually recommended a low-carb diet! Things are definitely changing.

It is important to practise meaningful eating! No hurry! Carefully chu each bite before to swallow it, for at least 20 times. I was taught this wisdom by my grandmothers since my very early age. Love and peace to all humans!

[@ketograssroots]

"We get this essential sugar from our diet" at minute 2.25. At this point I knew this was going to be biochemically inaccurate. There is no carbohydrate that is essential. As you know, there are essential proteins and fatty acids, but there is no requirement for carb to be eaten, as glucose etc. can be synthesized in the body from fats and protein. Oh dear! Two minutes in and they are spouting rubbish. However, I expect it will improve.... maybe. My CGM shows I spike with any carb, so I do not eat more than 20g net carbs a day. I stick with red meat, eggs, cheese and butter, and lost 31kg in a year, and reversed my diabetes and fatty liver, and got my blood results back to normal. I stay keto now. Mood always buoyant, energy good, slim and fit, and I've stopped snoring. Yay! Pass the butter!

In Ayurveda ( ancient Indian medicine) an individual approach is the base . They have 3 body types and each person is a combination of all 3, where 1 type is dominant. Same food and medicine can work differently for each person.

I would be tempted to cross reference the "junk DNA" with the genetic profile of gut flora to understand how or if this coding is correllated - next research question is simply a mattter of subtraction (assuming computation capability) and determining what percentage of our DNA (along with junk DNA) correlates to or influences gut flora. Such stimulating topics you choose.! I much prefer these docs to straight news or junk videos about personal opinions and emotional reactions.

[@kitarvin770]

Body and blood type, occupation, urban or rural living, and many more factors to consider.

[@paillette2010]

PBS Nova did this a few years ago. it's emerging science. Since the old model of energy in/energy out is based on burning food to count the Kcals. No one poops ash.

[@3naturalBionutrition]

Genetic testing will only reveal so much and it'll provide you problem areas and foods to eat or avoid. It's NOT to be used as a crutch or excuse but provide a path to a solution. A better approach is to consistently check your blood biomarkers and implement a personalized nutrition program based on evidence and science backed knowledge and techniques instead of rules and restrictions. The centerpiece of every nutrition program should be anti-inflammation, gut health and the consumption of nutrient dense high quality whole foods in a balmced manner along with optimal hydration (electrolytes and water). NOT a diet. With that said you still need discipline, sustainability, internal motivation and consistency. Along with regular physical activity and in some cases Natural, non-gmo herbal (not synthetic) supplementation. This was somewhat disingenuous because the alternative Sweeteners did NOT include stevia, monk fruit or allulose.

[@minakokataoka7112]

I am afraid this is too simplistic as the advice is solely based on glucose levels. You should not exclude other benefits of wholegrain bread over white bread. Just because the partcipant had less glycaemic response, you should not recommend eating white bread for healthy individual as wholegrain provides you more dietary fibre, magnesium, B vitamins etc. I believe nutritionists in this documentary know that. The individual differences in reacting different foods is nothing new. It’s actually published in 2008. Williams et al. British journal of nutrition 2008;100:364-372. You should not call it Personalised if you don’t consider other aspects of diet (eg. Cholesterols, BP, other bloods, and personal preferences & cultural aspects). Dietary advice is more complex than recommending fruit and veges.

Why can't we just fast track personalized nutrition by using A.I.? I think using A.I., we would be able to find out specifically what our bodies are tailored to a perfect personalized nutrition and pinpoint what each person needs. We all know there are a lot of factors why people are the way they are and if they want change, we also need to determine genes differences and everyone is different from one another, and only AI can computate exactly and in a short amount of time to determine what each person needs.

Another key factor that shouldn't be ignored with metabolism diseases is environmental pollution, packet food comes with additives, processed food(ham, sucuk, bacon etc.)and also fresh greens and fruits are subjected to unnatural or processed fertilisers and pesticides. Again, industrialisation has a significant role in changing our metabolism. Stress is another cause of metabolic diseases. Most of us have a sedentary life which also can aggravate the process. These are the downsides of consumer society.
