Importance Of The B Vitamins

It’s essential to eat foods containing all the B vitamins, as a deficiency of one affects others’ functioning. Consequently, it interferes with your metabolism (9). Here are other functions of these vitamins:

  • Thiamin helps in the synthesis of various hormones.
  • Vitamin B 2 helps the body in breaking down steroid hormones, fats, and drugs.
  • Niacin contains a coenzyme that helps in the expression of DNA in the body cells.
  • Vitamin B 6 helps in improving your immune functioning and brain development. It also helps in the metabolism of proteins and the creation of new red blood cells.
  • Folate regulates cell division in your body as well as the metabolism of amino acids. It is also recommended for pregnant women to reduce the risk of several congenital disabilities.
  • Vitamin B 12 creates new red blood cells, synthesizes DNA, and helps with neurological and brain functioning. It also helps in the prevention of pernicious anemia.
  • Vitamin B 5 is crucial for the health of the nervous system and the brain.

Foods Containing The B Vitamins

You must eat foods containing these vitamins regularly so that you meet your daily B vitamins value. Here are some excellent food choices you can try out:

  • Legumes such as soybeans and black beans
  • Whole grains such as brown rice, quinoa, and barley
  • Oatmeal
  • Lean and organ meats
  • Yogurt, milk, and other dairy products
  • Beef liver
  • Eggs
  • Chicken and other poultry

  • Fortified breakfast cereals
  • Nutritional yeast
  • Fortified plant-based milk such as soy or almond milk
  • Spreads like Marmite

Vitamin B Complex Supplements

If you are not getting enough B vitamins, you could be asked to start taking their supplements. You are only eligible for these supplements if you fit any of the following cases:

  • If You Are Vegan Or Vegetarian

Most foods containing these vitamins come from animal products. Therefore, if you are on a vegan or vegetarian diet, chances are you are not eating these products. So, you might likely be suffering from a deficiency of the B complex vitamins.

In this case, you may need to take supplements. Consult with a professional for more medical assistance on how to proceed with these supplements and your diet plan.

  • If You Are Expectant

If you are expectant, you will need to consume more foods containing these vitamins. In case this is not possible, then your doctor may recommend taking the vitamin B complex supplements. Experts acknowledge that folate deficiency in pregnant women can result in birth defects involving either the spinal cord or brain (3).  

Similarly, vitamin B 12 deficiency can cause pregnancy loss, fetal abnormalities, low birth weight, and high blood pressure in these women.

  • If You Are Aged 65 And Above

Seniors above 65 years old are highly likely to suffer from vitamin B 12 deficiency. They can take vitamin B 12 supplements under supervision as it reduces the aging effects of the brain. Vitamin B 9 supplements have also been linked to reduced depressive symptoms in these seniors.

Vitamins To Boost Metabolism: Vitamin D

Vitamin D is vital in our bodies for healthy bones. It helps prevent rickets, which is a disease associated with weak or soft bones (8). Initially, most people thought this vitamin was only significant for this role.

However, experts acknowledge that this vitamin has a myriad of health benefits. The vitamin is also crucial as it helps your body utilize calcium from your diet. Calcium is among the few minerals that help in boosting your metabolism.

It also helps in regulating your blood sugar levels and helping you attain healthy bones. Higher intakes of both calcium and vitamin D can help in promoting weight loss. The two help your body burn more calories, which can, as a result, make you shed extra weight.

You can acquire more calcium in your body by taking foods such as:

  • Milk and yogurt
  • Dark leafy vegetables such as kale
  • Fortified orange juice
  • Fortified cereals
  • Almonds
  • Seeds

Benefits Of Vitamin D

Aside from preventing rickets, this vitamin also helps you in the following ways:

  • Reducing Your Belly Fat

Experts have discovered that vitamin D deficiency is linked to total and abdominal fat in women. However, in the men’s case, low vitamin D levels were linked to fat in the abdomen and liver (2).

These researchers acknowledge that there is a strong association between low vitamin D levels and increased abdominal fat. Therefore, to help reduce this belly fat, women are advised to consider getting enough vitamin D.

  • Reducing Your Risk Of Several Conditions

It would help if you also had enough vitamin D in your body to minimize your risk of getting several conditions. These entail cardiovascular diseases, multiple sclerosis, glucose intolerance, diabetes, and hypertension.

  • Helping You Manage Your Diabetes

Vitamin D also increases insulin response in your body. Consequently, it helps you manage your diabetes.

Getting Vitamin D Naturally From The Sun

Sun basking is one of the natural ways you can increase your vitamin D levels. The sun is the best source of this vitamin, and all you need is a few minutes of your day. However, several factors may affect how much of this vitamin your body makes from the sun (4). They include factors such as:

  • The Time Of The Day You Sun Bask

Your skin tends to produce more of this vitamin at midday when the sun is scorching hot. However, rarely do most people sun bask at this time for fear of sunburns. Apply your sunscreen to avoid getting these sunburns.

Similarly, drink your water to prevent dehydration. These two factors will enable you to sun bask for long until your body produces enough vitamin D.

  • Your Skin Color

Pale colored skin makes vitamin D faster than dark-colored skin.

  • The Amount Of Skin Exposed To The Sun

Your body will make more vitamin D if you expose your entire body. So, do not just lie on your back or expose your feet and arms. Let your whole body be exposed to the sun, and for the recommended duration.

  • How Much Sunscreen You Apply

Wearing too much sunscreen hinders your body’s ability to make enough vitamin D. The key is to regulate how much sunscreen you apply to avoid sunburn and skin-related cancer.

  • The Duration You SunBathe

The duration you sunbathe is highly influenced by your skin color. If you have light skin, then you are advised to sun bask for at least 15 minutes. On the other hand, if you are dark-skinned, you are urged to sunbathe for a couple of hours.

You must be cautious to avoid exposure to the sun for long hours. It can increase your risk of developing skin cancer.

Vitamin D Supplements

Vitamin D is not present in many foods. Instead, the sun is the best source of attaining this vitamin. However, since most people do not get enough sunlight, they suffer from vitamin D deficiency. In this case, their physicians may recommend taking supplements.

The recommended daily dosage of Vitamin D varies according to age. Children aged 12 months and below are required to take 400 IU of vitamin D (7). If you range anywhere between 1 and 70 years, you must take a 600 IU daily dosage of vitamin D.

In case you are above 70 years old, then your daily dosage should be 800 IU. If taken in the recommended doses, these supplements are safe. If you take more than 4,000 IU daily and are expectant, breastfeeding, or above nine years, you will experience:

  • Constipation
  • Reduced appetite
  • Nausea
  • Weakness
  • Disorientation
  • Vomiting
  • Weight loss
  • Kidney damage
  • Confusion
  • Heart rhythm problems

Also, speak to your doctor if you are taking other medications. It will help in avoiding unforeseen health complications arising from the interactions of the different drugs.

 Minerals That Boost Metabolism

In addition to these vitamins, several minerals also help in improving your metabolism. They include calcium, magnesium, and iron. Magnesium is responsible for the chemical reactions that are involved in producing energy in your body. 

Without it, there is neither energy production nor metabolism. Besides metabolism, iron is also vital for hormone creation, and your body cells’ correct functioning. So, remember also to eat foods rich in these minerals.

Although there are supplements for these minerals, you should get these minerals from their food sources. You can acquire magnesium from foods such as (5):

  • Legumes such as black beans
  • Cultured yogurt
  • Peanuts, cashew nuts, almonds, and other nuts
  • Bananas and avocados
  • Dark chocolate
  • Whole grains such as quinoa
  • Whole wheat
  • Potatoes
  • Tofu
  • Spinach
  • Halibut and salmon

To get iron, eat the following foods:

  • Dark leafy vegetables
  • Soybeans and tofu
  • Meat
  • Nuts
  • Brown rice
  • Beans
  • Fortified cereals
