For The Love of Food

Welcome to Friday’s For The Love of Food, Summer Tomato’s weekly link roundup.

This week I found a surprisingly in depth and thoughtful piece on genetically modified foods, an even more impressive food commitment by Facebook founder Mark Zuckerberg, and a few good signs that the politics of food labels are headed in the right direction—truth.

Also, for you geeks my thesis work is finally published. Here’s the deets.

Junk Food

What truly liberated me from worrying about food all the time was shifting my thoughts and fears away from things I couldn’t or shouldn’t eat and instead focusing on delicious foods–foods I love–that also make me healthy. Changing my relationship with food in this way turned it from something that caused me anxiety to something that brought me pleasure.

One unexpected benefit of choosing healthy, tasty foods over bland diet foods was that many of my old cravings for sugary, unhealthy fare disappeared. While I have not found a clear scientific explanation for this, it stands to reason that a nourished body would be less prone to strong feelings of need toward certain foods. I was amazed how powerful it can be to focus on health instead of dieting. These days, really unhealthy foods barely even tempt me.

Upgrading your healthstyle will go far in helping you overcome your cravings, but as I much as I would love to tell you that you can eat any foods you want in any quantities you want, we all know this is not true. While you are focusing on eating more of the foods you love there are also foods that are generally worth avoiding as part as your daily healthstyle.

There is room for anything in a healthy life, but here are some foods that DO NOT promote health and can lead to weight gain:

• Sugar In any form, sugar wreaks havoc on your health and metabolism. Two keys to protecting yourself from sugar damage are quantity and timing. Do not eat too much sugar at once (stick to small desserts) and do not eat sugar very frequently. I try to limit real desserts to once or twice per week (max) and satisfy all other sweets cravings with fruit. Eating whole grains is particularly effective at reducing sugar cravings.
• Refined flour Processed grains (all flour) are almost as bad as sugar in their effect on your metabolism. In fact, your body processes them exactly the same way. Generally look for alternatives to breads, pastas and other foods made with flour. Instead focus on getting carbohydrates from intact whole grains. Try to limit refined flour foods to less than once per day. If you are actively trying to lose weight, I would make an effort to cut these out completely.
• Trans fat Twenty years ago scientists believed they had solved the problem of saturated fat by replacing it with an artificial solid fat made from plants. It turned out these processed fats, trans-fats, are one of the most dangerous foods you can put into your body. Not only do they raise your “bad” LDL cholesterol, they also contribute to lowering your “good” HDL cholesterol–a double whammy for your health. No amount of trans-fat is considered safe in the diet (the data is striking), and you should avoid these processed fats completely. Better to eat foods made with real butter. Better yet, choose healthy fats from vegetable sources like coconut oil, olive oil and canola oil.
• Anything processed It is worth emphasizing that nothing processed has ever proven to be healthier for you than real whole foods–even foods with fantastic health claims on the package. In fact, as Michael Pollan points out in his book In Defense of Food: An Eater’s Manifesto, a health claim on a package is a pretty good sign that a food is bad for you. There are no stickers for “Whole Grain” or “Low Carb” on your vegetables, and those are what you should be eating.
• Red meat As I discussed earlier this week, red meat is probably not good for you. Some people argue that it is really bad for you, and some people think it is not so bad. It appears to not be quite as bad as processed foods, but there are plenty of compelling reasons to limit how much red meat you eat. For myself personally, cancer is a bigger fear than heart disease. But there is also some data that saturated fat plays a role in insulin resistance. I recommend less than one (4 oz) serving of red meat per week. The same can be said about poultry with skin.

I do not recommend completely eliminating foods you love–even if they are bad for you–because this is not something you can maintain forever and it strips some of the joy from life. Instead I suggest trying a few customizable strategies to be sure that the less healthy foods you love bring you happiness, but do not damage your body:

• Reduce, Don’t Eliminate Simply being aware of how often you eat these foods and trying to stick to the guidelines above can drastically improve your healthstyle. If you currently eat a lot of sugar, processed foods or red meat, do not attempt to completely overhaul your diet overnight. Make changes gradually or it will be very difficult to make them permanent.
• Be Picky When you first start to upgrade your healthstyle, identify foods you can do without and those you can’t live without. Some changes will be easier for some people, while others are nearly impossible. Focus on the easier changes and do not beat yourself up over things that are difficult for you. Every little change you make will add up to a healthier you.
• Set Up Simple Rules It is often hard to keep track of everything you do or do not eat. A food journal or Twitter can help with this, but the simpler your healthstyle the better. Setting up simple, easy to remember rules for yourself can help you make healthy changes. The guidelines above are a great place to start. For example, if you decide in advance you can only have one dessert per week, you can be sure that the one you choose is well worth the wait. Use simple rules to both increase your good habits and decrease your bad ones. Experiment to find simple rules that work for you. For example, if you love to eat pizza make a deal with yourself that if you have it you must have a big pile greens on the side–this may also help you eat one less piece.

Please share with us the strategies and rules you use to upgrade your healthstyle!

This is the final post in the series How To Get Started Eating Healthy. Much thanks to those of you have shared your tips and insights in the comments so far. Summer Tomato will continue to build upon these ideas and help make it easier for you to upgrade your healthstyle.

Vegetables

Most scientists agree that diet plays an important role in heart disease, but until now there has been no comprehensive analysis of which dietary factors most strongly affect disease outcome. A new meta-analysis published in the Archives of Internal Medicine reviews six decades of research (1950-2007) to assess how different dietary factors affect heart disease. Vegetables, nuts, “Mediterranean” and high-quality dietary patterns are strongly protective, while trans-fat, foods with high glycemic index or load and a “Western” dietary pattern were shown to be harmful.

The Study

This new study is unique for several reasons. First, the authors were only interested in factors that influenced heart disease directly, not simply heart disease risk factors such as cholesterol levels. Also, emphasis was placed on high-quality studies designed to identify strong dietary associations (cohort studies and randomized controlled trials) with long periods of follow up (at least one year). They asked whether the studies they reviewed were consistent with other data such as epidemiological reports, and sought to establish a causal link between diet and heart disease outcomes. Another important goal of the analysis was to identify factors that lack sufficient evidence to be conclusive and require further research.

Results

In addition to identifying vegetables, nuts, high-quality and Mediterranean dietary patterns as being strongly protective against heart disease, they also found monounsaturated fats (e.g. olive oil), dietary folate (e.g. whole grains, not supplements), dietary vitamins C and E (not supplements), alcohol consumption (in any form) and omega-3 fatty acids from fish (not plants, e.g. flax) to be moderately protective.

Factors that were not associated with heart disease in this study were dietary supplements (e.g. vitamins C and E), total fat, saturated fats, polyunsaturated fats (from plants), meat, eggs and milk. It is important to note, however, that negative findings in this analysis are not necessarily indicative of a lack of causality. Rather, it may indicate insufficient data to observe a significant positive association.

Dietary Patterns

The authors point out that “only overall healthy dietary patterns are significantly associated with coronary heart disease” in the controlled trials, while “evidence for most individual nutrients or foods is too modest to be conclusive.” They suggest that the reason an association exists for dietary patterns and not individual nutrients is that patterns “have the advantage of taking into account the complex interactions and cumulative effects of multiple nutrients within the entire diet.” The authors recommend future trials test various dietary patterns for disease outcome, including cardiovascular disease and cancer.

Taking this further, most dietary factors that were shown to be protective when consumed as part of a healthy diet were not protective when taken in supplement form. This finding bolsters the argument that overall diet rather than individual foods or nutrients are the best strategy for protecting against heart disease. The authors conclude that their findings suggest “investigating dietary patterns in cohort studies and randomized controlled trials for common and complex chronic diseases such as coronary heart disease.”

Based on their analysis, the dietary pattern that best protects against heart disease is rich in vegetables, nuts, fish, healthy fats, whole grains, and fruit. Likewise, the worst dietary pattern consists of refined carbohydrates and artificial trans-fats. The lesson: the best diet consists of plants, fish and whole foods, while processed foods contribute to heart disease.

What about red meat and saturated fats?

Interestingly, there was insufficient data to conclude that red meat or saturated fats are harmful for the heart. This is not terribly surprising, since the data has always been inconsistent. However, I would point out that many studies have looked at the role of red meat and saturated fat in coronary risk and the outcome always shows either harm or no result. And as explained above, no result can be indicative of a lack of statistical power rather than lack of causation. Importantly however, I cannot recall a single study suggesting that red meat and saturated fat is actually good for you.

From this the best we can conclude is that red meat or saturated fat may be involved in promoting heart disease, but if they are the effect is likely to be less harmful than a diet of processed foods. Practically this means small doses of saturated fat may not do much harm when eaten as a part of an overall healthy diet. This is a fairly compelling argument for exercising moderation.

Conclusions

Before you run out and order a ribeye, keep in mind that heart disease is not the only debilitating chronic disease that plagues our culture. Red meat is also associated with several kinds of cancer. Likewise, refined carbohydrates are highly correlated with type 2 diabetes. Vegetables and whole grains are protective against these other diseases as well, and fish may play a role in protecting against neurodegenerative diseases.

The take home lesson is that both diet and disease are complex systems that involve innumerable factors in several different regions of the body. When choosing what to eat it is important that you consider the context of your overall diet and do not get caught up is single foods or a single disease threat.
