A misunderstood Vitamin

Vitamin A is vital for good immune function (viruses deplete vitamin A), fertility, skin health, and healthy hormones. If you get frequent colds in the winter, have dry skin or acne, fertility problems or have night vision issues, you may want to increase vitamin A-rich foods.

When you search for sources of vitamin A, you will find many books and articles declaring carrots and kale good sources of vitamin A. However, true vitamin A is found only in animal foods such as meat, fish, milk and eggs. Natural vitamin A consists of a mixture of different alcohols, esters and aldehydes (retinol,  retinal and retinoic acid).  All of these compounds are collectively referred to as vitamin A. Vitamin A is carried in the blood by retinol-binding protein (RBP), which is synthesized in the liver1. The storage form of vitamin A is retinol, which is stored by the stellate cells in the liver. Retinol is converted in the body to the active forms: Retinal, important for retinal function, and retinoic acid, which regulates gene expression and cell development. Synthetic vitamin A consists of retinol or retinyl palmitate, which needs to be converted to the active forms, whereas natural vitamin A provides all the different forms of Vitamin A. Interestingly, symptoms of vitamin A toxicity from synthetic vitamin A mimic those of vitamin A deficiency, possibly because an excess of the storage form interferes with the activity of the active forms.

Beta-carotene vs. Vitamin A

Plant foods contain carotenoids that can be converted to vitamin A by the liver and intestinal cells. Beta-carotene is the most common carotene and can be split into two molecules of vitamin A. Alpha and gamma-carotenes are less efficiently converted than beta-carotene. According to nih.gov, 1/2 cup of raw carrot provides ~9000 IUs of vitamin A from beta-carotenes. This assumes a 100% conversion rate of beta-carotene to vitamin A. However, actual conversion rates in humans seem to be much lower than 100%. A 2002 study found a mean conversion ratio of beta-carotene to retinol of only 3%2 in men given a beta-carotene supplement. The authors also found a conversion ratio of 14% for raw carrots consumed with 20g of fat, and 4%-8% for cooked carrots.

Conversion Rate of Beta-carotene

Furthermore, there are genetic variations in human ability to convert beta-carotene. Some individuals show little or no increase in blood beta-carotene after an oral dose of beta-carotene (they are called non-responders) 2. The conversion ratio in responders was found to be between 5 and 7%2. Conversion is also gender-dependent: men show a smaller rise in plasma beta-carotene than do women after a similar oral dose3, as well as dose-dependent: Vitamin A activity of beta-carotene was 50% with a small dose and only 3% with a large dose of beta-carotene4. In conclusion, vitamin A activity of carotenoids is variable, surprisingly low, gender and dose-dependent, genetically variable and dependent on dietary fats2. Therefore sufficient vitamin A can only be obtained from animal foods. The fact that vitamin A supplements, but not beta-carotene supplements, are teratogenic1 is likely due to the low conversion rate.

Vitamin A and Protein Metabolism

Vitamin A is also important for protein metabolism. A 2010 study on weanling rats found lower weight gain, higher protein catabolism and higher nitrogen excretion with vitamin A deficiency. The authors concluded that vitamin A deficiency may induce a catabolic state associated with growth hormone resistance and decreased expression of IGF-15.

Hence, elderly people with sarcopenia and malabsorption may benefit from vitamin A supplementation in addition to protein or amino acids.

Does Vitamin A cause birth defects?

Since vitamin A is essential for embryogenesis, growth and epithelial differentiationit as been implicated in teratogenicity. A widely publicized 1995 study found increased risk of birth defects with consumption of more than 10000 IUs of vitamin A/day from food and supplements during pregnancy6. However, the study did not differentiate between natural and synthetic sources, and all seven babies with cranial-neural-crest defects were born to mothers with high supplemental (synthetic) retinol intake. Natural vitamin A in food is a mixture of different isomers of retinol, retinal and retinoic acid, whereas synthetic vitamin A is retinyl palmitate or retinyl acetate. Since retinoic acid is needed for cell differentiation, supplementation with high doses of retinol may cause a functional retinoic acid deficiency if conversion to retinoic acid is low (just as supplementation with alpha-tocopherol causes a functional gamma-tocopherol deficiency), leading to birth defects (my hypothesis). In any case, this study does not provide evidence that high intake of natural vitamin A from food sources alone causes birth defects.

Sources of Natural Vitamin A

True Vitamin A is only found in animal foods. This means vegan diets do not supply vitamin A. Since vitamin A is a fat-soluble vitamin stored in the liver, stores will gradually decrease over time on a vegan diet so the effects of vitamin A deficiency will not be apparent for a while. Grass-fed meat has 5 times more vitamin A than grain-fed, and wild fish has higher levels than farmed (grain-fed) fish. Good sources are grass-fed liver, meats, grass-fed raw dairy, pastured eggs, wild fish and seafood. If you are looking to supplement, look for a natural, undistilled cod liver oil.

Soaking Grains, Nuts & Legumes https://reclaimyourhealth.me/2017/05/09/5-tips-for-a-business-refresh/ https://reclaimyourhealth.me/2017/05/09/5-tips-for-a-business-refresh/#respond Tue, 09 May 2017 11:05:43 +0000 http://www.demos.prettywebdesign.biz/engage/?p=360

How to maximize nutrition from Grains and Nuts

Whole grains, nuts and legumes offer an abundance of nutrients, especially magnesium, some iron, B vitamins and vitamin E. A lesser-known fact is that they are also high in anti-nutrients like phytic acid and enzyme inhibitors. Phytic acid blocks mineral absorption and enzyme inhibitors inhibit your digestion. Grains, nuts and legumes are seeds after all, and these compounds serve to inhibit sprouting until the time is right, i.e. in the presence of water. In addition, phytic acid and enzyme inhibitors serve the dual purpose of protection the seed from being eaten by animals.

Phytic acid or phytate, is a phosphorus compound that will chelate (i.e. bind) minerals like iron, zinc, calcium and magnesium, and prevent their absorption in the gut. This will greatly reduce your mineral absorption and can lead to deficiencies. And enzyme or protease inhibitors in nuts and legumes prevent protein digestion and can hurt the pancreas when consumed in large amounts.

Soaking, Sprouting and Fermenting

Soaking, sprouting or fermenting your grains, nuts and legumes will break down mineral absorption-blocking phytates and inactivate enzyme inhibitors. Our ancestors soaked, fermented or sprouted their whole grains, nuts and legumes before making them into porridges, breads, bean casseroles and other dishes. In India, rice and lentils were fermented for two weeks before being served. In Mexico, corn was fermented for up to two weeks using limewater to break down a protein that will bind vitamin B3, which causes pellagra when consumed in large quantities. Traditional sour dough bread recipes called for fermenting wheat for up to a week before baking it into bread. This has the additional advantage of pre-digesting gluten to make it more digestible.

In today’s fast food world we have forgotten these traditions and are instead consuming grains, nuts and legumes without these precautions. The well-meaning nutrition advice to consume plenty of whole grains, raw nuts and cooked legumes can result in mineral deficiencies and digestive problems if not prepared properly. Here is how to prepare these foods for easy digestion and maximum mineral content:

Whole Grains

Soak whole grains in water which 2-3 tablespoons of something acidic (like lemon juice, whey or vinegar). Cover and leave in a warm place for 7-24 hours. Most grains require soaking for only 7 hours (rice, oats, millet, wheat) though they can be soaked longer, but quinoa is very high in phytates and requires 24 hours. Transfer to a pot, including the soaking water. Add more water in case of oats. For other grains like rice, bring to a boil until the water is at the level of the grain, skim, reduce heat, stir in salt and butter/ghee/coconut oil and cook over lowest possible heat for about 45 minutes (15-20 mins for oats).

Breads: Use only whole grain sourdough bread that is leavened for 7 hours or more and avoid yeast.

Nuts and Seeds

Nuts contain not only phytates but also enzyme inhibitors. Soak 4 cups whole, raw nuts (untreated so they can still sprout) for at least 7 hours or overnight in water with 1 tablespoon of salt. Then dry in an oven or dehydrator at 150 degrees F until dry. For 12-24 hours. Your nuts will still be raw.

Before drying you can flavor your nuts with tamari, salt or other flavors of choice.

Legumes

Cover legumes with warm water. Stir in 2-3 tablespoons of whey or lemon juice and leave in a warm place (lentils for 7 hours, beans and chick peas for 12-24, change water after 12 hours). Drain, rinse, place in a large pot and add water or broth/stock to cover. Bring to a boil and skim off foam. Reduce heat and simmer covered at low temperature until done (1-4 hours depending on the legume).

Note: Grains can be cooked in their soaking water but not legumes.

Anti-inflammatory Diet 101 https://reclaimyourhealth.me/2017/05/09/create-a-beautiful-life/ https://reclaimyourhealth.me/2017/05/09/create-a-beautiful-life/#respond Tue, 09 May 2017 11:00:52 +0000 http://www.demos.prettywebdesign.biz/engage/?p=356

What is an Anti-inflammatory Diet?

Do you suffer from chronic conditions like heart disease, depression, diabetes, allergies or arthritis? And have you been told there is no cure? Instead your symptoms have to be managed with medication for the rest of your life while your health slowly worsens?

What if you can take charge of your health and reverse or even eliminate your condition?

All chronic conditions have one thing in common: inflammation. This common denominator leads to an overactive and at the same time weakened immune system. Inflammation makes your blood stickier, depletes your body and brain of precious nutrients, and causes pain. It is also a major cause of weight gain or unability to lose weight. Many people I work with do not overeat calories, but still were unable to lose weight before coming to see me.

What can you do?

The answer is an anti-inflammatory diet while healing and rebalancing digestion and gut flora.

Sugar, white flours and certain vegetable oils are always highly inflammatory, but sometimes perfectly healthy foods can cause inflammation for certain individuals. Therefore, a healthy diet is not a one-size-fits-all. With functional medicine testing we can identify inflammatory foods and design a customized diet plan. And personalized supplementation can be very helpful for healing the gut, the root of inflammation. Once the gut is healed, previously inflammatory foods may no longer cause inflammation. While everyone is different, here are some general principles of anti-inflammatory diets:

Anti-inflammatory Diet Tips

  • Avoid sugar and artificial sweeteners, and use honey, stevia or maple syrup instead in moderation. Also avoid white flours and refined starches.
  • Avoid highly processed oils such as corn, soy or canola.  Choose healthy fats like olive, avocado, sunflower or coconut oils and grass-fed butter (yes, you read that right) instead.
  • A lot of people benefit from avoiding gluten found in wheat, although sometimes other grains, as well as corn, soy or dairy can also cause inflammation.
  • Vegetables, grass-fed meats and wild fish tend to be the least inflammatory foods. Eat lots of fresh vegetables, berries and fish and make use of your local farmer’s market at this bountiful time of year.
  • Balance Blood Sugar! High blood sugar disables function of some white blood cells and feeds inflammation. Keep your blood sugar low by always adding protein and healthy fats to every meal and snack.

I have seen year-long joint pain go away and blood pressure normalize in just a few weeks on an anti-inflammatory diet. The power of nutrition still amazes me, though sometimes targeted supplements are helpful for a time to correct an imbalance that would take much longer with fix with food alone.

In addition, there are many herbs and spices with strong anti-inflammatory properties, that you can incorporate into your cooking or take in supplement form.

Turmeric is probably the best-known anti-inflammatory and is commonly used for osteoarthritis and irritable bowel syndrome. Other spices like ginger, garlic, cumin, clove and even chili peppers are anti-inflammatory as well as antimicrobial. Culinary herbs like oregano, thyme, chives, and cilantro, to name just a few, all help fight microbes and lower inflammation as well.

To quote Hippocrates: “Just as food causes chronic disease, it can be the most powerful cure”.
