Nutrition and HIV Part 2


Welcome to another day in my life. Today is Thursday and I hope you are having a safe and great week so far. It is another busy week for Dab the AIDS Bear and me.

Yesterday, I started a three day blog on nutrition and living with HIV. Today is the second in a three blog series on the topic.

Recent data have shown that mono-unsaturated fats decrease the risk of certain cancers, and have an anti-inflammatory effect. Since AIDS in an inflammatory disease, mono-unsaturated fat intake is a factor in managing AIDS, too.

Combining carbohydrates with protein, fiber, and fat. Protein, fiber, or fat will slow the absorption into the blood of glucose from carbohydrates, which helps to reduce the rise in blood sugar and insulin spikes. So, mixing carbohydrates with protein, fiber, and good fats is one way to reduce their problematic effect on blood sugar and insulin. Ensure that every meal and snack you consume has a mix of these three macronutrients. But what are the best fats, protein, and high-fiber carbohydrates sources out there?

Fats and oils.

There are a number of different kinds of fats. There is motor oil, there is butter, and there are essential fatty acids. The most important oil to keep a Honda running right is not the kind with essential fatty acids (EFAs), but if you want to help your body stay healthy and your immune system operating at its best, you had better consider getting these EFAs on a daily basis. They are called "essential" because your body cannot manufacture them, and must obtain them from an outside source, like food or supplements. These oils are necessary for every critical function in your metabolism, including building lean body mass and fighting infections.

The main point is that since we need EFAs and other fats for health, we should be getting them in our diets from fresh, high-quality sources. A proper diet reduces the amount of starchy carbohydrates while maintaining a certain amount of healthy fats so that there is a different macronutrient balance than the old high-carbohydrate, high-protein, low-fat diets contained. This means striving to get fatty acids from several sources, the least of which are the saturated fats in butter or animal fat. Understand that saturated fats are not the demons we have been led to believe. When we realize that we evolved getting a certain amount of saturated fat from foods in the wild, it is only logical that they would have a place in a healthy diet. One recent study showed that dietary saturated fat and mono-unsaturated fat were associated with healthy testosterone production in humans, while EFAs had no effect. So it appears that we need a little saturated fat for optimal hormonal health. However, most people get far too much saturated fat, which promotes insulin resistance and metabolic problems, and not enough EFAs, which are needed for healthy cells and immune function.

The other important kind of fat that we should consciously include in our daily diet is mono-unsaturated fat, which we get from foods like olive oil. Recent data have shown that mono-unsaturated fats decrease the risk of certain cancers, and have an anti-inflammatory effect.14 AIDS is an inflammatory disease, so mono-unsaturated fat intake logically has a place of importance in managing AIDS, too.

Vegetarian or vegan diets present a challenge to people with HIV or AIDS who need a full spectrum of amino acids and micronutrients. Unless you are vegetarian for ethical reasons, consider eating eggs and fish.

Fatty acid recommendations . EFAs include the omega-3 and omega-6 fatty acids. Most people get an imbalance of these two by consuming too small an amount of omega-3 fats, which have anti-inflammatory properties, and relatively too large an amount of omega-6 fats, which tend to promote inflammation when out of balance. To get more omega-3s, eat more fish, including salmon, tuna, sardines, anchovies, mackerel, rainbow trout, and herring. Omega-6s are contained in common vegetable oils, like sunflower, safflower, and corn oils. Try to reduce your intake of these.

Oils and cooking.

Olive oil is one of the best oils to cook with. You can also cook with high-oleic sunflower oil, avocado, canola, macadamia, or any oil that is high in mono-unsaturated fatty acids.

Avoid cooking with oils made from corn and sesame. These oils contain more omega-6 fats, and less mono-unsaturated fats, so they have a higher potential for spoiling and turning to trans-fats, which are bad for the immune system. Try to avoid any intake of these oils when they are not absolutely fresh.

Also, choose oils that are minimally processed. Most of the clear oils in supermarkets are stripped of some of their natural components to make them more suitable for sitting on store shelves for long periods of time without spoiling. Do not use these stripped oils. When you do cook, do not overheat the oil so that it smokes, which causes the formation of carcinogens and destroys the beneficial fatty acids.

Avoid margarine, hydrogenated fats, or processed oils. Do your best to avoid processed fats or oils, as they have negative effects on cellular health, overall metabolism, and your immune system. Look out for the words hydrogenated and partially-hydrogenated. These kinds of manipulated fats probably do increase the risk of cancer and heart disease. They also weaken healthy cellular immune metabolism, which means that they might increase HIV progression. Lastly, they are also likely to promote high lipid levels and insulin resistance.

Protein, food for the immune system.

Dairy protein fractions, such as caseine (contained in milk curd) and whey, are at the top of the list of proteins that optimally feed lean body mass growth. In dairy products, the amino acid balances, insulin-raising potential, and overall growth factor content add up to one thing: milk proteins were created to make mammals grow bigger. While there is a lot of hoopla related to which dairy protein fractions are best, there is more misinformation than reality in this area. Those with lactose intolerance should be careful in their selection of milk-based products. Aged cheeses and yogurt may be more tolerable for those who cannot digest lactose.

Egg protein.

Next on the list are egg proteins. The important thing to remember is that whole egg is probably somewhat better than egg white for lean body mass growth and overall health effect, because the yolk is a rich nutrient source, and its protein content complements the protein in the egg white. Together they are a better source of protein.

Meat protein.

While real food like meat often seems to take a back seat to protein powders because of a mindset created by slick advertising, professional athletes know the value of real food related to lean body mass growth. If you do not make real food and meat fundamentals in your diet, you will not grow lean body mass tissue as well. Fish, chicken, turkey, and beef are vitally important foods, not only because of their protein content, but because they contain numerous other nutritional components that are important for a healthy metabolism. The message is: eat real food, then supplement food with protein powder drinks if you need them.

Lean red meat is a superior source for lean body mass growth and blood-building nutrients. These include creatine, carnitine, phenylalanine, conjugated linoleic acid (CLA), and heme- (blood) iron, the most absorbable form of iron. And meat, in general, is less likely to cause allergic reactions than eggs or dairy proteins, like casein and whey. The only caution about red meat is that the high amount of saturated fat most commercial red meat contains could promote metabolic problems. So be moderate about including it in your diet and choose leaner meats if you do.

Important details on meat: cooking kills bacteria in meats. Stewed meat is better for digestion (chicken soup, beef stew). Roasting is okay. Try not to fry or barbecue with charcoal. Charred foods are associated with increased risk of gastrointestinal system cancers. Any cooking of meat or vegetable protein that causes the formation of a hard outer skin renders the protein that becomes the skin to be much less digestible because it cross-links the protein.

Vegetarian diets

It is very difficult to gain lean muscle weight on a vegetarian diet. In fact, it is almost impossible for most people, especially when they are fighting infections that burn lean body mass. While I know a very few HIV-positive people who can do well adhering to a vegetarian regime, I find that the vast majority cannot do it and keep their lean body mass. Additionally, vegetarian diets increase the potential for anemia because of a lack of blood-building components such as highly absorbable heme-iron and vitamin B12.

If you do choose a vegetarian diet, your best protein sources are beans, seeds and nuts. Digestion of nuts and seeds will be improved by soaking them overnight to reduce the enzymes they contain that inhibit digestion of proteins. If you can eat them without digestive problems, many nuts and seeds are ideal foods because they contain protein, healthy fat, and complex carbohydrates in a very good balance for overall health. They also make a great snack between meals. However, the amino acid balances in these proteins do not appear to be optimum for lean body mass growth for humans. Again, vegetarian or vegan diets present a challenge to people with HIV or AIDS who need a full spectrum of amino acids and micronutrients. Unless you are vegetarian for ethical reasons, consider eating eggs and fish.

I will conclude this topic tomorrow with the third blog. Hope you have a great Thursday!

Until we meet again; here's wishing you health, hope, happiness and just enough.
