Want to Improve Your Memory? Try these things…


There is little more frustrating than not being able to remember something. Especially the stupid little things that you should remember, like the person you talked to yesterday who said they ran into your sister; or, when you meet someone new and forget their first name literally a split second after you shake their hand. Does that happen to anyone else?!


Memory tends to fade as we age. That is inevitable. This is partly due to the natural aging process, partly due to the nutrient deficiencies often seen in the elderly, and partly due to the decrease in brain stimulation that some elderly people experience. I know some elderly people who work hard to retain their memory power by doing things like Sudoku, crosswords, and other brain teasers. No matter what your age, doing activities that make you think – make your brain work a little harder than normal – are all good for memory. We need to keep those neurotransmitters fresh and active! (I have provided a Sudoku below if anyone wants to get going on their brain exercises for the day…).








Nutrition can also be a good tool for improving memory. Some people believe that cognitive function is directly related to nutritional status. In fact, some studies show that Alzheimer’s disease is directly correlated with a low intake of essential nutrients. The B-vitamins are crucial for memory and brain function. Thiamin, or vitamin B1, actually mimics the effects of acetylcholine inside our bodies. Acetylcholine is the neurotransmitter involved in memory, and supplementation of thiamin has actually shown improved memory function in Alzheimer’s patients. Foods that contain high amounts of thiamin include sunflower seeds, tuna, green peas, black beans, lentils, and pinto beans.










Vitamin B12 is directly linked to nerve function. When someone has a B12 deficiency, they may experience things like tingly or numb hands or feet; memory loss; brain fog; and other cognitive issues. Many studies have shown that B12 levels inside the body tend to decline with age, and supplementation of B12 can be a powerful tool for those with impaired brain function. Foods high in vitamin B12 include calf’s liver, snapper, venison, grass-fed beef, lamb, scallops, shrimp and halibut.


Ginkgo biloba extract is an herb used to help increase memory and brain function. The studies on ginkgo biloba are ongoing, with some seeing positive results and others concluding that it does little for the brain. However, I have spoken with some people who have tried ginkgo biloba and had success. Ginkgo biloba not only increases our brain capacity, but it also normalizes acetylcholine receptors, which helps improve our brain function. Ginkgo biloba extract can be bought in supplemental form at most health foods stores, or ordered online.








Lecithin is a fatty substance found in animal and plant tissues such as egg yolks, soybeans and organ meats. This is one reason it is so important to eat the entire egg, not just egg whites! Since lecithin is made up of fat, and our brain is mostly fat, it makes sense that a diet high in lecithin will help the brain. Our brain depends on these healthy fats to keep the cell walls in tact so proper messages can be sent and received. In addition to brain health, lecithin helps prevent cardiovascular disease by increasing excretion of cholesterol and bile acids, and aiding in proper fat digestion. It also helps keep our liver healthy.


Finally, increased vitamin E in the diet can help protect our nerve cells. It acts as an antioxidant and prevents free radical damage to nerve cells, which are crucial for brain function. Whole food sources of vitamin E include sunflower seeds, almonds, olives, spinach, papaya, and leafy greens.







Did you finish the Sudoku yet?

Water-Soluble Vitamins, Part 1 of 2


Hi guys! Check out PWN blog featured in Urban Baby Gourmet’s March/April newsletter! If you scroll down to the “Blogs We Love” section, you can read about it. I am so honored to be featured and cannot wait to have these great Denver ladies guest blog at PWN in a few weeks! To all the Denver moms out there – you will absolutely LOVE their business and their products.

I hope the information on fat-soluble vitamins yesterday was helpful. Today, let’s move on to water-soluble vitamins: the eight B-vitamins and vitamin C. Just to be clear up front, I will give you the names of the B-vitamins. Some have multiple names so it can be confusing, but here they are: thiamin, riboflavin, niacin, biotin, pantothenic acid, B6, folate, and B12. Vitamin C is sometimes referred to as ascorbic acid.

Whereas fat-soluble vitamins travel through our lymph system before being absorbed into the blood, the water-soluble vitamins go directly to the blood. They travel freely without need of transporters. Since they are water-soluble, they are stored in the watery parts of the body, and the kidneys function to excrete any excess in the urine.

Remember when I told you that fat-soluble vitamins are stored for long periods and you can go months or even years before becoming deficient? Well, that’s not the case with water-soluble vitamins. They are needed every few days, and preferably every single day. Since they are not stored for very long and are excreted through our urine, we need to replenish often. Therefore, it is easier for someone to become deficient in their B-vitamins or vitamin C.

Below is a very brief overview of each of the water-soluble vitamins. I’m going to give you half today, and half tomorrow, so as not to overwhelm. Each one is important – take note of which foods these vitamins are concentrated in and try to include them in your diet each day.

Vitamin C: Vitamin C’s primary function is to manufacture collagen, which is the main protein substance for the human body used in things such as connective tissue, cartilage and tendons. It is also a strong antioxidant. The best food sources of vitamin C include broccoli, brussels sprouts, peppers, potatoes, guava, kale, parsley, waterress, red cabbage, strawberries, papaya, spinach, oranges, lemons, grapefruits, and calf’s liver. Exposure to air destroys vitamin C content in foods, so try to eat quickly after you slice. And if you’re eating lunch at a salad bar, keep in mind that most of the fruits or vegetables you are choosing have probably already lost almost 50% of their vitamin C content (disappointing, I know!). The major deficiency symptom is scurvy (bleeding gums, poor wound healing, extensive bruising). Other signs of possible vitamin C deficiency include depression, hysteria or susceptibility to infection.





Thiamin (B1): Thiamin is necessary for brain energy and mental function. Signs of a thiamin deficiency include mental confusion, muscle wasting, fluid retention, high blood pressure, and difficulty walking. The best food sources of thiamin include brewer’s yeast, wheat germ, sunflower seeds, pine nuts, pecans, split peas, millet, pistachios, oatmeal, whole wheat flour, cashews, brown rice and garlic. Alcohol and the tannins in coffee can both destroy thiamin completely, so try to consume separately.

Riboflavin (B2): This vitamin is used in energy production and protection against free radicals. Deficiency symptoms include cracked lips or corners of the mouth, sensitivity to light, cataracts, burning or itchy eyes, and anemia. The best food sources of riboflavin are brewer’s yeast, calf liver, almonds, wheat germ, wild rice, mushrooms, millet, kale, cashews and broccoli.

Niacin (B3): Remember when I talked about metabolism a few months ago? Niacin is a key nutrient used in metabolism. It also helps regulate blood sugar and high cholesterol. Food sources include brewer’s yeast, wheat bran, peanuts, wild rice, sesame seeds, sunflower seeds, brown rice, and almonds. Signs you may be deficient in niacin are dermatitis, dementia, and diarrhea.



Pantothenic Acid (B5): Pantothenic acid helps us utilize fats and carbohydrates to produce energy during metabolism, and also to manufacture adrenal hormones and red blood cells. Deficiencies are very uncommon, because its food content is so high. Foods containing pantothenic acid include brewer’s yeast, calf liver, peanuts, mushrooms, split peas, pecans, soybeans, oatmeal, sunflower seeds, lentils, cashews, broccoli, brown rice, avocados, and kale.

That’s enough for one day… more tomorrow!
